Some Types of Tool Boxes for Storing and Transporting Your Tools

wrenches, screwdrivers, pliers, cutters, hammer, axe, drill machines, and other hardware tools.

Whether you are a fan of do-it-yourself home and vehicle repairs and maintenance or not, it goes without saying that every adult possesses at least some basic tools and related equipment. On the other hand, workers like electricians, plumbers, and carpenters own a much more elaborate and extensive collection as their trade requires them to be well-prepared for fixing a number of things.

If you are looking for the different types of toolboxes that you can use to house and organize your hardware equipment then take a look at the following article.
Because they can be constructed in various ways and are available in countless styles, it is almost impossible to cover all the types of aluminum storage cases in one go. The article highlights the most popular ones according to use and also discusses the basic types of tool boxes classified according to their material.
While the earliest tool boxes, date as far back as the beginning of the 19th Century, were carved out of wood, today you will hardly find any toolbox constructed from the same material. Instead, modern toolboxes are mostly made of materials such as steel and aluminum because compared to wood, they stronger yet lightweight at the same time.

According to the choice of material, the following are the different types of aluminum carry cases available in the market.
Aluminum is employed in the construction of tool boxes for the same reason that it is used in making all modern airplanes – it is strong and lightweight.
These toolboxes are made from aluminum sheets of sufficient thickness. The sheets usually feature a rugged texture or a rugged diamond plate pattern that is commonly used for various aluminum surfaces which can otherwise be too smooth and slippery for certain uses.
Besides being a sturdy and durable material, aluminum is often preferred for making various types of tool boxes because it does not corrode and therefore will not deteriorate for a significantly large time period. These toolboxes are also used in trucks because they prevent the tools from moisture and rust. In such aluminum carry case, they mostly come with gas struts which help to keep the lid open and upright, making it feasible for the workers to easily access the items inside.

The durability and strength of aluminum tool boxes are further increased by covering their inner and outer walls with a special powder. This powder coat makes them more resilient to rust and corrosion. Steel tool boxes provide exceptional strength and are easy to clean and care for.
Despite the higher price, you can find the toolboxes in residential as well as commercial garages and even in race environments because they have the longest life, are resilient to chipping, dents and bumps, plus they are super easy to clean and maintain.

As a professional aluminum boxes manufacturer with many years of experience, we have a complete industrial chain, superior product quality and thoughtful service.

Types of Hourglass

Types of Hourglass
Before the invention of mechanical clocks, timepieces used the sun’s motion or simple measurement devices to track time. The sundial may be the best known ancient keeper of time, and it is still manufactured as a popular garden accessory—but for its visual interest, not for practical time measurement. Stonehenge, the giant monument built of upright stones on the Salisbury Plain of Wiltshire, England, may have been used as a sundial and for other time and calendar purposes. Sundials have obvious disadvantages; they can’t be used indoors, at night, or on cloudy days.
Other simple measurement devices were used to mark the duration of time. Four basic types could be used indoors and regardless of the weather or time of day. The candle clock is a candle with lines drawn around it to mark units of time, usually hours. By observing how much of the length of a candle burned in one hour, a candle made of the same material was marked with lines showing one-hour intervals. An eight-hour candle showed that four hours had passed when it had burned down beyond four marks. The clock candle had the disadvantages that any changes in the wick or wax would alter burning properties, and it was highly subject to drafts. The Chinese also used a kind of candle clock with threads used to mark the time intervals. As the candle burned, the threads with metal balls on their ends fell so those in the room could hear the passage of the hours as the balls pinged on the tray holding the candle.
The oil lamp clock that was used through the eighteenth century was a variation and improvement on the candle clock. The oil lamp clock had divisions marked on a metal mount that encircled the glass reservoir containing the oil. As the level of oil fell in the reservoir, the passage of time was read from the markings on the mount. Like the candle clock, the oil lamp clock also provided light, but it was less prone to inaccuracies in materials or those caused by drafty rooms.
Water clocks were also used to mark the passage of time by allowing water to drip from one container into another. The marks of the sun’s motion were made on the first container, and, as water dripped out of it and into another basin, the drop in water level showed the passage of the hours. The second container was not always used to collect and recycle the water; some water clocks simply allowed the water to drip on the ground. When the eight-hour water clock was empty, eight hours had passed. The water clock is also known as the clepsydra.
Sand timer hourglass (also called sand glasses and sand clocks) may have been used by the ancient Greeks and Romans, but history can only document the fact that both cultures had the technology to make the glass. The first claims to sand glasses are credited to the Greeks in the third century B.C. History also suggests sand clocks were used in the Senate of ancient Rome to time speeches, and the hourglasses got smaller and smaller, possibly as an indication of the quality of the political speeches.
The hourglass first appeared in Europe in the eighth century, and may have been made by Luitprand, a monk at the cathedral in Chartres, France. By the early fourteenth century, the sand glass was used commonly in Italy. It appears to have been widely used throughout Western Europe from that time through 1500. The hourglass or sand clock follows exactly the same principle as the clepsydra. Two globes (also called phials or ampules) of glass are connected by a narrow throat so that sand (with relatively uniform grain size) flows from the upper globe to the lower. Hourglasses were made in different sizes based on pre-tested measurements of sand flow in different sizes of globes. A housing or frame that enclosed the globes could be fitted to the two globes to form a top and bottom for the metal sand timer and was used to invert the hourglass and start the flow of sand again. Some hourglasses or sets of hourglasses were set in a pivoted mount so they could be turned easily.
The earliest writings referring to sand glasses are from 1345 when Thomas de Stetsham, a clerk on a ship called La George in the service of King Edward III (1312-1377) of England, ordered 16 hourglasses. In 1380, following the death of King Charles V (1337-1380) of France, an inventory of his possessions included a “large sea clock … in a large wooden brass-bound case.”

John Harrison and his brother James were introduced to clock repair by their father, Henry. At the time, clock making, or horology, was undergoing a developmental revolution. Mechanical clocks had existed since the fourteenth century, but had remained rather primitive in their operation until Christiaan Huygens invented the weight-and-pendulum clock in 1656. One limitation was that they were totally dependent upon the earth’s gravity for their operation. This meant that they could not keep accurate time at sea, and could not be adapted for portability. Even moving them across a room would require adjustment.
The Harrison brothers set to work on developing a marine chronometer in 1728. The motivating factor was money. In 1714, the English Admiralty set up an award of £20,000 for anyone who could provide mariners with a reliable clock that, when used with celestial sightings, could keep them informed of their longitude at sea. Mariners had to rely heavily on dead reckoning to find their way, often leading to tragic results.
The Harrison strategy was to design an instrument that was not only internally accurate but also externally stable. The Harrisons made several models of marine chronometers. The fourth model proved to be the most successful. On a nine-week voyage from England to Jamaica in 1761, the device had only a five-second error.
The Board of Longitude, apparently miffed that a common artisan had achieved the coveted goal, reluctantly gave up only half of the prize. John, minus his brother, refused to accept only half of the reward and persisted until the other half was relinquished.
The Board subjected his invention to undue scrutiny and required him to design a fifth model. This time, Harrison outdid himself by designing a compact timepiece that resembled a modern day pocket watch. It was far more convenient than the previous models, which were heavy and bulky. The Board still refused to capitulate. Finally, only a personal appeal to King George III and the King’s intervention could set things right, and Harrison received the full reward in 1773 at age seventy-nine. Harrison lived only three more years.

These two early associations of sand clocks with the sea show how navigation had become a time-dependent science. Compasses and charts, developed in the eleventh and twelfth centuries, helped navigators determine bearings and direction, but time measurement was essential to estimating distance traveled. The sand glass may have been invented —or perfected—for use at sea where equal units of time were measured to estimate distance; by contrast, on land, unequal time measurements were more important because activities depended on the length of day.
The great advances in maritime science occurred in the twelfth century with the development of the magnetic compass in Amalfi, Italy. Other Italian port cities like Genoa and Venice contributed to the astronomical advances in navigation, and, by coincidence, Venice was the world’s greatest glass-blowing center. Furthermore, the fine marble dust from the quarries at Carrara was perfect for use as sand in navigational sand clocks. As well as measuring time as distance at sea, hourglasses were used by the navies of several nations to “keep the watch” or measure the time the crew worked. The ship’s boy was in charge of turning the hourglass; to get off work early, he would “swallow the sand” or turn the glass before it was empty.
The most extraordinary hourglasses were made as gifts for royalty. Charlemagne (742-814) of France possessed a 12-hour hourglass. In the sixteenth century, Holbein (1497-1543) the artist made spectacular hourglasses for Henry VIII (1491-1547) of England. Other sand glasses contained multiple instruments. For example, a sand glass made in Italy in the seventeenth century contained four glasses. One had one-quarter hour of sand; the second, a half-hour of sand; the third, three-quarters of an hour of sand; and the fourth contained the full hour’s measure of sand. Some glasses also had dials with pointers, so, with each turning of the glass, the number of turns could be shown with the pointer to mark the cumulative passage of time.
The upper and lower globes of each glass were blown separately with open apertures or throats. To join them so that sand could flow from the upper globe to the lower, the two halves of the glass were bound together with cord that was then coated with wax. The two-coned glass phial could not be blown as one piece until about 1800.
In about 1500, the first clocks began to appear with the invention of the coiled spring or mainspring. Some weight-powered clocks had been made before 1500, but their size limited their practicality. As the mainspring was improved, smaller, tabletop clocks were manufactured and the first watches were made. Mainspring-driven clocks made curiosities out of clepsydras and sand glasses, but, interestingly, the most beautiful hourglasses were made after 1500 as decorative pieces. There are many types of hourglasses, such as metal hourglass,wood hourglass and so on.
By the 1400s, many private homes had sand clocks for household and kitchen use. Sermonglasses were used in churches to track the length of the minister’s sermon. Hourglasses were also routinely used in the lecture halls of Oxford University, craftsmen’s shops (to regulate working hours), and in England’s House of Commons where bells to signal voting and lengths of speeches were timed based on sand clocks. During the height of the sand glass, doctors, apothecaries, and other medical practitioners carried miniature or pocket sand glasses with durations of one-half or one minute to use when timing pulses; the practice of carrying these continued until the nineteenth century. Today, miniature versions containing three minutes worth of sand are sold as egg timers and as travel souvenirs. Larger sand clocks are still made today of ornamental materials and in interesting styles for use as decoration. All of these measuring devices (clock candles, water clocks, and sand clocks) have the disadvantage that they must be watched carefully.
How to use a massage ball
Like a foam roller, a massage ball can also be used to help release tension in our achy muscles after long hours spent in the office or after a workout. One of the differences being that it can get to those hard to reach areas such as the upper back, buttocks and feet. “Knots” or “trigger points” can be massive sources of pain in our bodies and using self-massage techniques can be very satisfying. Before diving in, there are a few important things to know which will help you achieve the best results.
Why a massage ball
Massage balls are affordable and small and therefore they can easily fit into a suitcase or handbag to use wherever you go. They also promote self-sufficiency so there is no need to rely on anyone else. Notwithstanding, it does not always give the same results as a traditional massage delivered by an experienced therapist
Find the right ball
There are many different types of massage balls ranging from very smooth and firm like a lacrosse ball to small and soft like a squash ball. Other balls include a tennis ball and the trusty spikey massage ball. To each his own but if you’re new to using a massage ball, perhaps start with a spikey ball or a tennis ball.

Where and when
Since they are so conveniently easy to use, you can use them almost anywhere for example against a wall, the back of a chair, on the floor or use your hands. Some office workers keep them at their desks as a reminder to use them during the day to help with releasing built-up muscle tension from poor posture or stress.
Start with only a few knots at a time, the most painful area being first. The idea is to trap the knot in the muscle with the ball and apply gently to medium pressure until the painful sensation has faded. Once you have the correct spot (and you will know when), hold it there and try to relax until only about 80% of the ache remains. When pressing too firmly, the sensation can be too painful for you to relax which defeats the purpose of using the massage ball in the first place, it could also potentially irritate the area. You are looking for a “good pain”.Roll the ball around to look for more tender spots or just enjoy gently going back and forth over the tight muscle. If you feel the muscle needs it, you can repeat it twice a day. After releasing the knot, follow it up with gentle stretches to the same muscle. It’s okay to lightly exercise the muscle afterward but avoid fatiguing it for 24 hours.

The gear shift knob in a manual transmission equipped car or light truck is the large knob, usually made of plastic, that attaches to the top of the gear shift lever. Over time the surface of the knob can wear and you might wish to replace it to spruce up the interior of your vehicle. Many aftermarket manufactures offer specialty gear shift knobs. Some of these are made out of exotic materials such as leather or billet aluminum. Some companies offer novelty gear shift knobs for owners who want to personalize the interiors of their vehicles.

Stainless Steel Pipe Types

Stainless Steel Pipe Types
Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Based on the end use of the pipe, stainless pipe is broken down into several categories.
Since the development of stainless steel over hundred years ago, it has become world’s most used and popular material. Since stainless steel has the notable corrosion resistance that helps in increasing features with chromium content. The resistance can be shown in reducing acids as well as against pitting attacks such as in chloride solutions. It requires low maintenance, and is familiar to luster thus making it an ideal and best material for SS pipes.
This versatile material is indispensible in wide industries. This may contain number of application especially for SS pipes that benefit user with positive properties.
Iron-containing alloys made from more than two chemical elements are known as stainless steel. It is widely been used in comprehensive range of applications. Stainless steel alloy is basically steel alloy with iron, nickel, and chromium percentage contents in abundance.
The stainless steel has been in presence for centuries, since it is vulnerable toward corrosion and works better in tough condition. The stainless steel gets recognized late in year 1800’s with a combination of iron-chromium with offered rust resistance. Since, then it is mold into stainless steel pipes so that it gets used for number of industrial applications.
In 1912, a researcher of brown-firth laboratory founded a martensitic SS alloy finally. The new material got labeled as Staybrite. The stainless steel alloy comprises of iron alloy with minimum amount of chromium up to 10.5%. You can see tremendous variety of alloys in the market, the only thing they differ is in chemical composition. The alloying elements are titanium, nickel, carbon, copper, nitrogen that can boost formability, strength, and other SS properties.
The stainless steel pipe is available in different product type such as welded pipes and seamless pipes. The composition may vary and this makes it possible to use it in respective industries. Generic industrial company use stainless steel pipe for regular use.
Different Types of Steel Tubing and Stainless Steel Piping
Pipes and tubes are sometimes difficult to classify, and tend to be distinguished based on function. In addition to these classifications, stainless steel is also distinguished by type and grade.
304 Stainless Steel Pipe
For tubing and piping applications, type 304 stainless steel is a common selection because it is highly chemical- and corrosion-resistant. However, type 304 stainless steel is not compatible with applications where temperatures fall between 800 and 1640 degrees Fahrenheit (F) because it is prone to carbide precipitation, a result of the material’s .08 percent carbon content limit. Stainless steel type 304L circumvents this problem because it has a lower carbon content limit, and therefore can be subjected to welding and higher temperature applications. Other types of stainless steel often possess additives (such as nickel or molybdenum) which strengthen traits that are desirable in particular applications.
Stainless Steel Tubing for General Corrosion-Resistance
Stainless tube general category of steel is appropriate for applications that require corrosion resistance above other traits. Ferritic or martensitic types of steel (those made with the most chromium) are manufactured to be either heat-treated or annealed. Austenitic Stainless steels (those with high chromium and nickel contents) offer even more resistance, and can be used under the same general conditions as ferritic and martensitic types.
Stainless Steel Pressure Pipe
This type of stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe.
Stainless Steel Sanitary Tubing
For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion-resistance, doesn’t tarnish, and is easy to keep clean. For specific applications, different tolerances can be achieved. The grade typically used for these applications is ASTMA270.
Stainless Steel Mechanical Tubing
In applications such as cylinders, bearings, and other hollow formed parts, stainless steel mechanical tubing is typically used. Tubing can manipulated to have a variety of cross-sectional shapes, such as square and rectangular, in addition to the more traditional, round tubing cross-section. Typically, ASTMA 511 and A554 grades are employed for mechanical tubing applications.
Stainless Steel Aircraft Tubing
In highly-specific aircraft applications, chromium and nickel type stainless steel is used because of their heat and corrosion-resistance. Found in applications that require high-strength, stainless steel aircraft tubing can be work-hardened or welded, although work-hardened pieces shouldn’t be used with some kinds of corrosive substances. Low-carbon types of stainless steel are a common choice for welded parts.
For applications that require seamless and welded tubing in larger sizes (1.6 to 125 mm in outside diameter), aircraft structural tubing is used—this type of stainless steel is manufactured according to Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs).
Aircraft Hydraulic-Line Tubing
Another type of aircraft tubing, aircraft hydraulic-line tubing is used in aerospace applications as fuel-injection lines and hydraulic systems, and tends to be small. It is often manufactured from types 304 or 304 L stainless steel because of the steel’s high-strength, corrosion-resistance, and ductility.

AP pipe, or Acid Pickling, uses acidic solutions such as nitric acid and fluorine acid to
Remove the oxide layer of the steel pipe. Cheap and fast, but easy to cause grain boundary corrosion and rough inner and outer surfaces
The roughness is easy to have suspended impurities attached. AP literally means pickling surface, and in the category of clean products, it means pickling surface + oil-free cleaning
MP Tube-Mechanically Polished Pipe
MP tube : Mechanical polishing is often used for the oxide layer on the surface of steel pipes,
The brightness and effect of holes and scratches depend on the type of processing method. In addition, after mechanical polishing
Although it is more beautiful, it will reduce the corrosion resistance, so when used in a corrosive environment, it needs to be passivated.
reason. And there are often polishing material residues on the surface of the steel pipe
BA tube-Bright Annealed Pipe Bright Annealed Pipe BA is the bright annealing Bright Annealing steel pipe in the process of drawing will definitely need grease lubrication and the grain will also be deformed due to processing. In order to avoid this grease remaining in the steel pipe, in addition to cleaning the steel pipe, you can also use high temperature annealing at high temperature to eliminate deformation, using argon as the furnace atmosphere, and further clean the steel pipe by combining argon with the carbon and oxygen on the surface of the steel pipe. The surface has a bright surface effect, so this method of using pure argon annealing to heat and quickly cool to brighten the bright surface is called bright annealing. Although the use of this method to brighten the surface can ensure that the steel pipe is fully clean and free of any external pollution. However, if the brightness of this surface is compared with other polishing methods mechanical, chemical, and electrolytic, it will feel like a matte surface. Of course, the effect is also related to the argon content and the number of heating times.
EP tube ElectroPolished Pipe (EP 0 (Electro Polishing) Electropolishing is the use of anodizing method to appropriately adjust the voltage, current, acid composition, and polishing time through the principle of electrochemistry. Not only can the surface become bright, Smooth and clean effect 0 can also improve the surface corrosion resistance, so it is the best surface brightening method, of course, its cost and technology also increase. However, because electrolytic polishing will highlight the original state of the steel pipe surface, if the steel pipe surface has serious scratches and holes.

How to choose video intercom?
Choosing the video intercom the buyers often do not know a lot about this product. This is not surprising because the video intercom appearedrecently in our lives in comparison with other household utilities (such as TV, telephone, notebook etc). That is why to find more information about a video intercom buyers begin to surf the Internet to find the answer: how to choose video intercom? This article can help you to solve the problem. With our help you will find the real answer.
Color or black-white picture?
First of all you have to answer the question yourself do you need the video intercom with black-white picture or more up-to-date color video intercom? Both these variants should be discussed. The black-white variant fits perfectly for the office. But for the private house it is better to choose one of the color video intercoms to make the atmosphere at home secure and comfortable. The video intercom as any other thing in your house is the interior design item. That is why it should fit in the interior.
As far as we began to talk about the interior we should notice that the manufacturers present their equipment in three color schemes, namely: white, black and grey metallic. Everything depends only from your wishes.
Anyway having chosen do you want a black-white video intercom or the color one we can move along. Farther we will discuss the color video intercom because we should keep up with the times.
Do you need a handset?
As far as the model range is very various it’s time to speak whether you need a device with or without handset. At first let’s discuss the one with a handset. What is the main advantage? It is noteworthy that with a help of handset you can talk with a visitor and others around you won’t hear your conversation what is really necessary sometimes. The video intercom without handset also has own advantages. Firstly, it is very convenient. Secondly, it is up-to-date. The manufacturers expanded the model range without handsets and designed models with touchscreen.
As a result we can say that you have lots of choice. And it would be easily to make up your mind what you like. Someone likes to use the handset whether others want to use up-to-date function ?Hands free?.
Is the CRT size important?
So you choose whether you want the black-white or color video intercom and also make up your mind do you want it with or without handset, than it’s time for you to pay your attention what CRT size you want. The manufacturer Commax Co, Ltd. offers you CRT size 3.5, 5, 7 and 10.2 inches. That is why first of all you should measure the place where you want to install your video intercom. It’s important because sometimes people buy devices and during installation they clear up that there is not enough place for installation. Also you should remember that the devices you’re going to use should be handy for you.
What the diagonal influences on? It influences on the pictures that is why the bigger the image is the more details you can see. If truth to be told, it doesn’t affect anything, but you shouldn’t spare on the outdoor panel. If you choose the video intercom with the diagonal more than 5 inches, you should take the according panel. Selectingthe outdoor panel you should pay your attention on what viewing angle does it have. For example, for the 5-inches video intercoms fit perfectly outdoor panels with viewing angles V 75°, H 55°.This is enough big viewing angle and you will receive quality image. To compare if we choose, for example, the outdoor panel with theviewing angles V 55°, H 40° for the 5-inches intercom you should be ready that the image will be stretched.
So if you choose the intercom with big diagonal you should remember that you need an according panel. For the monitor with smaller diagonal fits the outdoor panel with smaller viewing angles. Whether you want big or small picture – it’s you to choose.
Additional features
Choosing the Tuya video intercom you should remember that it can have additional features. The main function is to monitor the visitors that stand behind your door during the call. If you buy the 4 Wire Analog video intercom only for this reason you can you choose the simplest model. But the manufacturers continue updating the production. For example, you can choose the model with memory it means that if you’re not at home and you have a visitor, the intercom will record the image automatically. Also you can connect additional cameras besides the one which is in an outdoor panel.
Let’s sum up everything. Besides the fact the model range is quite huge, to decide what you want is not so hard thing to do. No one apart from you can decide what do you like most of all.

Chapter One – What are Alumina Ceramics?
Alumina Ceramic Liner is an industrial ceramic that has high hardness, is long wearing, and can only be formed by diamond grinding. It is manufactured from bauxite and can be shaped using injection molding, die pressing, isostatic pressing, slip casting, and extrusion.
Products made from alumina, some of which are shown in the image below, are wear, chemical, erosion, corrosion, and high temperature resistant and bioinert, making them perfect for medical implants.
Alumina ceramics are a technical ceramic due to their properties and price to performance ratio. The classification of alumina ceramics is based on their alumina content, which can vary from 70% to 99.9%. The higher the purity of alumina, the stronger is its wear and corrosion resistance.
Chapter Two – Properties of Alumina Ceramics
Alumina ceramics are made from a white granular material that is similar to table salt or a very fine silky dense powder. The three general types of alumina are hydrated, calcined, and tabular. Each type has a variety of grades.
The types of alumina vary according to the amount of soda (Na2O), iron (Fe2O3) and silica (SiO2) they contain as well as their chemical purity and the properties of the powder used in the production process.
To produce calcined alumina, aluminum oxide is heated to 1050° C or 1900° F. The super heating removes all chemicals and water creating a very pure, 99.99% pure, with a 9 on the Mohs hardness scale, which is just below a diamond’s Mohs rating of 10.
Alumina hydrate, or alumina hydroxide, is used as a glaze because of its ability to stay in suspension in glaze slurries and adhesive qualities.
Tabular alumina is produced by heating aluminum oxide to 1650° C or 3000° F. It has a high heat capacity, excellent thermal temperature, strength, and volume stability. It is formed from sintering balls of calcined alumina, which are crushed to form a powder. Tabular alumina has high refractory properties, mechanical strength, wear resistance, chemical purity, dielectric properties, and corrosion resistance in acids and alkaline.
Properties of Alumina
High Temperature Ability
Alumina is used in oxidizing and reducing atmospheres up to 1650°C or 2900°F as well as vacuum environments of 2000°C or 3600°F. At 1000° C, it keeps 50% of the tensile strength it has at room temperature. While metals are weakened by high temperatures, alumina ceramics retain their strength when they return to normal temperatures and are unchanged.
Abrasion Resistant
Abrasion wears down a material by rubbing it away by friction. The resistance to abrasion means a material will maintain its original structure even after mechanical wear. Alumina ceramics are high in abrasion resistance due its hardness.
Chemical Resistance
Alumina is resistant to acids and alkalis at high temperatures because it is inert, not chemically reactive, which makes it resistant to the effects of chemicals such as solvents and salt solutions.
The density of a material is its mass divided by its volume, which is read as grams per cubic centimeter (g/cm3) where grams is mass and cubic centimeters is volume. As the volume increases, the density of the material increases. Alumina ceramics are made from fine particles that do not allow for voids in the material. The fewer voids means the material has high volume and density. The density of alumina ceramics varies according to the temperature. At 25° C, its density is 3.965 g/m3 at standard atmospheric pressure.
The mechanical properties of a material is determined by its strength, which is the amount of stress and strain it can endure. Alumina has superior strength and hardness that improves with the purity of the different grades.
Alumina has high resistivity and reduces thermal shock. The increased purity of alumina increases its resistivity.
Alumina ceramics make a perfect insulation material because of its dielectric equality, the inability of an electric current to pass through them.
Hardness tells the ability of a material to be able to endure mechanical wear and abrasion. Alumina ceramics are harder than steel and tungsten carbide tools. They are harder than sapphire and are excellent for mill linings and bearings. According to Rockwell hardness, alumina ceramics are at HRA80-90, second only to diamonds and above stainless steel.

ZTA ceramic liner is zirconia toughenedalumina ceramic liner ,belonging to inorganic non-metallic materials, is a good wear-resistant materials. Zirconia toughening alumina ceramic is added pure 99 Zr02 zirconia, the particles form ZrO2 toughened alumina ceramic. Alumina toughness can be significantly improved when zirconia is added as appropriate. It can be said that the toughening of alumina ceramics is the toughening method most used at present, and about 20% zirconia (ZrO2) is added to toughen the alumina.
ZTA toughening effect mainly comes from the following mechanism:
(1) to make the aluminum oxide grain refinement.
(2) Zirconia phase change toughening.
(3). Micro-crack toughening.
(4). Crack steering and bifurcation. Zirconia toughened alumina mechanical properties: ZTA

1300, fracture toughness 6.0, flexural strength 480MPa, compressive strength 3600MPa, ZTA toughening alumina ceramic liner is added on the basis of alumina zirconia ceramic ingredients, abrasion resistance and toughness between the alumina ceramic and zirconia ceramics, zirconia ceramics because the higher prices, the user once The larger the amount investment, the largest number of manufacturers are mostly European and American companies and BHP Billion and other groups.
What is Concrete Pump Pipe?
Concrete pump pipeline is used with concrete pumps to ensure that the concrete is delivered correctly and safely to where it needs to be. It’s an essential part of truck-mounted concrete pumps, trailer pumps, or placing booms. The concrete pump pipe is the most wearing component on a concrete pump as it has the biggest contact and the most friction with the concrete. The durability of pipes is one of the major factors to the pumping efficiency.

O-Ring Types and O-Ring Material Makeup – A Guide

O-Ring Types and O-Ring Material Makeup – A Guide
Rubber O rings are a form of gasket or seal that features a round cross-section. They are commonly used to prevent leaks of either fluids or gases from occurring in products, systems, or machinery and find use across a variety of industries. Because of their low cost, simple production process, ease of installation, and pressure resistance, they have found application in a lot of common products, such as automobiles and engines. The aerospace industry useso-ringsin many types of rockets and aircraft applications.
This article will review information on the types of o-rings and material options available, along with their suitability for different applications.
Selection Factors
The fact that o-rings can function in so many applications is largely attributable to the fact that there is a wide range of materials available from which they may be fabricated.This range of selection allows the designer to consider the properties of the material and select a suitable option based on how well that material performs against the expected operating conditions of the application. The factors that are usually considered when selecting a material for an o-ring include:
The material’s compressibility or hardness (durometer)
The performance against environmental and operational conditions, including:
Corrosive chemicals
The abrasion performance of the material
The permeability of the material (permeation)
The cost of the material
O-rings are usually produced from some form of elastic polymer or elastomer. These polymers are cured, often through vulcanization, resulting in improved strength, durability, and elasticity. Different materials have different properties, though, with some exhibiting greater elasticity and others possessing more tear-resistance.
Temperature range:Between -100 degrees Fahrenheit and 500 degrees Fahrenheit.
Suited forTongueurePTFE O ringsare very rigid and hard to apply, butPTFEencapsulated o-rings handle surface wear well, in addition to exhibiting corrosion and abrasion resistance, non-permeability, chemical inertness, and low absorption.
Avoid:Like silicone,PTFEis rigid and is better suited to static applications.
Applications:Examples of PTFE o-ring uses include automotive steering devices and paint guns.
O-rings Information
Solid O-ring is solid-rubber seals that are shaped like a doughnut. When pressed between two mating surfaces, O-rings block the passage of liquids or gases.
Types of Seals
O-rings can form a static or dynamic seals. A static seal is where the O-ring does not move and is used simply for containing pressure or maintaining a vacuum.Dynamic sealscan be reciprocating (like a piston and cylinder), or rotating (shaft rotating in a housing). Straight threads used with O-rings provide a better seal than tapered threads used alone.
A boss seal is also an O-ring, however it does not fit the standard sizes for an O-ring. A boss is a cylindrical projection on a casting or forging. The end of that projection is machined to provide a flat, smooth surface for sealing.
Application Methods
Axial squeeze and radial squeeze are two methods for applying an O-ring. An axial squeeze is when the ring is compressed parallel to a line drawn through the center or axis of the ring. In a radial squeeze the ring is compressed between the internal diameter (ID) and overall diameter (OD).
Imporant specifications for hollow O-ring include size, material, hardness rating and features.
Rubber X-ring is a torus (donut) shaped seal with a clover shaped cross section. Because of the clover design, the X-ring has a lower coefficient of friction and has multiple sealing surfaces on each side increasing its sealing ability and reduces the amount of force needed to seal and so extends the life of the seal. X-Rings are interchangeable with O-rings especially where lower coefficient of friction values are required.
X-Ring Advantages
The design of an X-Ring eliminates the effect the flash lines has on its sealing ability. In an O-Ring flash lines are on the outer and inner diameter, which are sealing surfaces. Excessive flash can effect the ability of the sealing surface to provide a tight seal. On an X-Ring flash is not an issue.
The grooves on the sides of the X-Ring can retain lubricant, lowering friction and extending the life for the seal. Also, the X-Ring’s clover leaf design provides 2 sealing surfaces per side as opposed to one sealing surface per side on an O- ring. With the multi-sealing seal points on one ring, less compression is needed to obtain an effective seal. Less friction and wear will ultimately increase service life and reduce downtime.

All-rubber V-rings

Rubber V-ring is used for rotating shafts in an extremely wide range of applications. The V-ring can be used alone to protect a wide assortment of bearing types from contaminants while reliably retaining the lubricant. They are also often used as secondary seals to protect primary seals in highly contaminated environments.

V-rings are installed on shafts and their thin, tapered lip seals against a counterface perpendicular to the shaft. V-rings have an interference fit on the shaft, rotate with it and act as flingers. Angular misalignment of the shaft relative to the counterface can be tolerated. V-rings provide reliable sealing even if the shaft is out-of-round or rotates eccentrically. The amount by which the shaft can be displaced axially is governed by the permissible displacement of the V-ring relative to its counterface.
V-rings are made entirely of elastomers without fabric or metal reinforcement and are therefore easy to install. They can be stretched and, depending on size, pushed over other components like flanges, pulleys or even housings. This is a very valuable feature, especially when replacing a seal.

Four Reasons to Use Air Hoses Instead of Hydraulics
In the manufacturing world you might ask when or why should I use air hose instead of hydraulic hose?Pneumatics follow the same power movement principle as hydraulics except it involves the movement of gases instead of fluids.While pneumatics and hydraulics each have their ideal places in a wide range of industrial operations, there are times when it’s beneficial to use air hoses to meet your needs.
Four Reasons to Use Air Hoses
1. Clean power: Pneumatics is cleaner than hydraulics.If there’s a leak, only air isreleased instead of slick fluids which are dangerous and hard to clean.
2. Easy Set-up: It is normally easier to set-up because many industrial facilities already provide compressed air.
3.Long Term Investment: Pneumatic equipment might be more expensive overall than hydraulic equipment, but generally it requires less maintenance and has a longer operating lifespan.
4.Speed:Although air hoses aren’t made for high pressure applications, they provide for rapid movement operations.They are designed with speed in mind, not strength.
The real-world applications for air hoses are seemingly beyond measure as they can be used in all forms of industrial automation.Air hoses can supply power to cylinders and vacuum pumps as well as funnel compressed air to jackhammers, staplers and impact tools.They can even be used to provide vehicle functionality for mobile equipment and can also be used in areas of agriculture, mining and drilling.Having been designed for age, weather, and oil resistance, this type of hose is suitable to transport air in multiple workplace environments and conditions.

Some packaging types to consider

Remember the feeling when you picked up your first iPhone? Taking off the plastic seal and feeling the sleek white box? By touching the box for the very first time you already felt the importance, quality & significance of this device. This is no coincidence! We meticulously strategized how they were going to package their product to align with their branding of providing top of the line product innovation & consumer experience! 

It is clear that packaging plays a large role in the perceived value of a product and as a whole, the packaging industry really hasn’t changed too much in the past years, compared to the constant innovations made in portable technology. With all the packaging and box choices available in today’s market, it often becomes difficult to select the most appropriate packaging solution for your product. Let’s take a look at some of the different types of packaging options you can use to enhance your product & customer experience!

1. Cardboard boxes
Paperboard is a paper-based material that is lightweight, yet strong. It can be easily cut and manipulated to create custom shapes and structures. These characteristics make it ideal to be used in personalized packaging. It is made by turning fibrous materials that come from wood or from recycled waste paper into pulp, and then bleaching it. Paperboard packaging comes in various grades, each suitable for different packaging requirements.

SBS (or solid bleached sulfate) paperboard can be used for packing cosmetics, medicines, milk and juice, cosmetics, frozen food and more. Choosing kraft, or CUK (coated unbleached kraft) paperboard packaging are for those who prefer the natural and environmentally-friendly look of recycled paper, which can be used for similar packaging applications. Kraft is often seen to be less resistant to moisture, making it less suitable for food-related products, or frozen-goods packaging. With the right combination of design options, paperboard packaging can look high-end, without high-end pricing.

2. Corrugated boxes
Corrugated boxes simply refer to what is commonly known as: Cardboard. Corrugated boxes are the ones many probably consider as ‘cardboard’ as it produces the large shipping, shoe & storage boxes.  What a lot of people do not realize is that corrugated boxes also come in different types depending on the durability and strength of the box. Identifying a certain corrugated material, however, is easy. How do you determine the material? Through its corrugated medium (also known as fluting).  Identifying a corrugated material is easy. It consists of 3 layers of paper, an outside liner, an inside liner and a corrugated medium (also known as fluting). The corrugated medium that gives it strength and rigidity.

3. PVC boxes
Plastic is used in a wide range of products, from spaceships to paper clips. A number of traditional materials, such as wood, leather, glass, ceramic, and so on, have already been replaced by plastic. PVC box packaging has many advantages in which they can be recycled, and generally they are much more durable than paperboard boxes. Airtight plastic packaging containers can help to preserve the quality of food and eliminate any contamination issues. Plastic packaging also does not break easily and can be stored with food under extreme conditions.
Another reason why plastic is a popular choice for packing material is because of its ability to showcase the product at any angle without necessarily opening the packaging. It is also flexible, lightweight and can be applied with films or coating to enhance packaging appearance.
Contrary to popular belief, plastic is in fact recyclable, in the sense that it takes less energy to produce new plastic, compared to glass, and other materials. Best of all, it is very cost effective!

4. Paper tube packaging 
Paper tube packaging is becoming popular globally. It provides a unique packaging alternative. Paper tube packaging is lightweight that makes it easier to transport. They also provide good protection to the packaged product from damage and contamination. It is also eco-friendly and thus contributes to conserving the environment. Paper tube packaging is being widely used in different industries like cosmetics, food products, etc. 
The packaging industry has seen a move towards sustainable packaging. Product packaging that is not eco-friendly creates unnecessary junk that ends up either in landfills or into ocean beds. Such packaging is harmful to the environment. Customers are becoming more aware of the dangers of non-degradable packaging and are preferring products using eco-friendly packaging.
Paper tube packaging is 100% eco-friendly. It is biodegradable and does not leave behind harmful packaging waste. Paper tube packaging can be easily recycled which saves a lot of energy and resources that would have gone into preparing fresh packaging. Using paper tube packaging helps you to position your brand and product as eco-friendly. This will provide you a competitive edge in the market and attract more customers into buying your product.

5. Paper bags
Paper bags have been part of trade and commerce for more than centuries. Traditionally cloth and jute bags were used to pack goods in larger quantities during its transfer from manufacturer or farms to retailers and shopkeepers then used the paper bags to distribute smaller quantity goods to end customers. In fact, paper bags are still used by small food retailers like – sweetshop owners, street food vendors, bakers and by small vegetable sellers.
On the other hand, a waterproof paper gift bag’s structural firmness and surface feature made it ideal to print high-quality images, logo, designs better as compared to a plastic bag, and that made paper bags a hit for fashion, luxury and premium gift packaging industry.
This trend has gained popularity owing to the people and businesses becoming more aware of the ecological surroundings. Also, several individuals want to use paper bags because they are easy to carry, clean and can hold items for a good duration of time.

This section is based on the material used for each type of partition wall. The durability and cost also vary with each type of wall. Walls made of concrete and reinforced concrete or steel materials are stronger than the walls built by Asbestos and the Plaster of Paris. The attractiveness and beauty of the wall also depend on the type of material used. There are some dividing walls that are not built with individual materials. They are made of composite materials. Using composite materials can add strength, beauty, and durability to walls. [/font]

Fan types and home air purifier

Like many, most individuals could not speak about the differences between ventilation fans and exhaust fans off the top of their head. In fact, many would think they are one in the same. However, that couldn’t be farther from the truth. Each fan serves specific purposes in both commercial and residential spaces that are crucial for supplying high-quality air throughout an area. This blog post will serve the purpose of describing the difference between these two types of intake air fans.
Ventilation Fans
As the name implies, ventilation fans are used to ventilate a residential or commercial space. This  works to bring fresh air from the outside and into the enclosed space. It helps circulate air through the building or home, which prevents individuals from breathing stuffy, less oxygenated air. Without ventilation, you and other individuals will be left breathing air that is not fresh.
Exhaust Fans
When pollutants and contaminants enter the air, exhaust fans remove them in order to provide clean air. Some common contaminants and pollutants include smoke, moisture, dust, and odors. Smoke from cooking and moisture from a hot shower can efficiently be removed from the air by this type of intake fan. If these contaminants are not removed from the air, you will subject your lungs to possibly breathing in harmful particles.
Differences Between These Fans
Both ventilation fans and exhaust fans work to create the freshest, cleanest air possible in the space they are installed. The main difference between the two types of fans is their application. While a ventilation fan works to bring clean air into an enclosed space from an outside source, an exhaust fan removes pollutants from the indoor air in a home or commercial space.
Industrial Fans, or industrial air purifier is perfectly positioned to supply you with the ventilations fans or exhaust fans you need to keep the air in your commercial or residential space fresh and free of contaminants. Each fan has its own unique properties and application, so it is important to place them in the correct space. In addition, selecting a fan with the proper CFM (Cubic Feet per Minute) is crucial to ensuring the fan operates as intended. A CFM that is too low will not be able to provide you with pristine air because it cannot move the air through the space efficiently.

How does Backward Curved Centrifugal Fan work?
The name, ‘Centrifugal Fan’ is derived from the direction of flow and how the air exits the fan impeller radially from the outer circumference of the fan. A Backward curved centrifugal fan is characterised by its cylindrical shape, several large curved blades and a conical inlet nozzle. The optimum operating area for a backward curved centrifugal fan is an area in the middle of its performance characteristic. A backward curved centrifugal fan works best when medium pressures and medium volume flows are required.

Because of the type of construction employed, these fans lend themselves easily to multistaging if higher pressures are required. [/font][/font]

An AC duct booster fan is basically a fan that can be attached to the ductwork in an HVAC system. Designed to increase the airflow to the more distant parts of a home, a duct fan will typically be installed in long sections of ductwork and then hooked up to an electricity supply. Do inline duct booster fans work? Yes! Inline duct fans are built to be installed inside the ductwork itself. Because they can shift large volumes of conditioned air, inline fans are often used in larger properties with extensive networks of air ducts.
Inline booster fans look somewhat like a regular section of ductwork. They are designed to replace a section of regular ductwork, so it is essential to choose one with the same dimensions as your existing ducts.
An inline booster fan will cost somewhere in the region of $30 to $200 (not including installation costs), but once installed, they are cheap to run and do not use much in the way of electricity.

Portable air purifiers
You’ll find several types. Basic mechanical models use a fan to force air through a filter to remove particles. Those with higher-grade HEPA filters are certified to capture the smallest particles, including dust, smoke, pollen and pet dander.
Electronic home air purifiers are designed to create an electric charge so particles stick to metal plates in the machine, which you then carefully wipe off. Other models include a UV light and claim to kill mold and bacteria, but Consumer Reports has not tested those models, and there’s currently no evidence that they do what they claim, Santanachote says.

[font=georgia, “Times New Roman”, serif]Some purifiers include an activated carbon filter to absorb odors and/or remove gases. While thicker, heavy-duty carbon filters are effective, they are ­pricey. Thin mesh ones are a waste of money, Santanachote says.
[font=georgia, “Times New Roman”, serif]Expect to spend at least $200 on a portable unit. Top-rated models that purify large spaces may run up to $700. In addition, replacement filters cost $20 to $200 (a few models come with washable filters), and because experts recommend that you run purifiers 24/7, you’ll have to factor in electricity.[/font]

[font=georgia, “Times New Roman”, serif]Don’t be dazzled by sleek looks or equate higher cost with better performance. Look for models certified by the Association of Home Appliance Manufacturers (AHAM). Then check the Clean Air Delivery Rate (CADR), which describes how well the machine reduces tobacco smoke, pollen and dust. The higher the number, the better. Less than 60 is poor, and more than 240 is excellent, Santanachote says.[/font]

Want to build parent-child relationships between custom post types created with CPT UI

I’ve gone through similar queries from the past but couldn’t find a solution that works for me.

So I created 3 different custom post types with the CPT UI plugin. They are called ‘careers’, ‘vacancies’, ‘our-staff’, respectively.

What I want to achieve is set ‘careers’ as the parent, and both ‘vacancies’ and ‘our-staff’ as children of ‘careers’, so that the breadcrumb lists on the children pages dynamically show as follows:

Home > Careers > Vacancies

Home > Careers > Our Staff

In the CPT UI interface, hierarchical is set to ‘true’ for all 3 custom post types.

For the two intended children pages ‘vacancies’ and ‘our staff’, ‘Parent’ is set as ‘careers’.

However the breadcrumb lists on the intended children pages still show as

Home > Vacancies

Home > Our Staff

i.e. skipping the parent page.

When I try getting the parent page ID of the children pages, it shows as "0" meaning the parent page is not set as intended.

I’ve tried using the Add-Hierarchy-Parent-to-Post plugin, but no luck….

Would be grateful for any tips, including workarounds to get the result I am hoping for.
