- Q: What is the heat preservation material used in a laboratory furnace?
- Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
- Q: What are the specific raw materials for plastic pallets?
- With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.
- Q: What is the density of a super high alumina brick and what is the price?
- Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan
- Q: Difference between low creep high alumina brick and ordinary high alumina brick
- The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.
- Q: What are the characteristics of high alumina bricks?
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
- Q: What is the difference between high alumina brick and clay brick?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: What kind of material is the general metal case?
- Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- Q: What is the difference between metal compounds and metal solid solutions?
- Sigma phase belongs to Affirmative system, there are 30 atoms in the unit cell, two element alloy, sigma phase formation is related with the following conditions: (1) the atomic size difference, phase difference between the maximum sigma atomic radius of a tungsten cobalt, the atomic radius difference is 12%. (2) there is a set of cubic lattice elements (coordination number 8), and another component is face centered cubic or dense six square lattice (coordination number is 12). (3) appear in "average number of races" (s+d layer electron number) in the range of 5.7 ~ 7.5. The region of the presence of sigma in the two - element alloy is shown in table 3. In the three element system, the concentration and temperature range of the formation of the sigma phase are affected by the addition of third components. Usually in chromium stainless steel in Fe Cr phase, in Fe - Cr - Mn three yuan, sigma phase iron chromium and chromium can form Mn two element, when the addition of manganese in stainless steel, will promote the formation of sigma phase, and stabilizes the wide temperature range. Many of the Fe Cr alloy elements. The phase temperature range increases. In less than 820C stable Fe Cr phase, silicon promotes the formation of D phase and the stable temperature increased to 900 to 960 DEG C, manganese and molybdenum can improve the temperature stability of sigma phase to 1000 DEG C.
- Q: What are the categories of bricks?
- Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
