- Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car
- 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 hot blast stoves.
- Q:High alumina brick 80 with which high aluminum cement?
- Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
- Q:What materials are used for roof insulation?
- There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
- Q:How are the grades of high alumina bricks differentiated?
- If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not exactly the sameFor example, European countries limit the content of Al2O3 for high alumina refractory materials at 42%.
- Q:Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
- Q:The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is fired at 1300 - 1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q:Is glass wool inorganic thermal insulation material?
- The use of glass wool, glass wool is usually used as raw materials of various types of insulation materials, such as glass wool board, glass wool, glass wool, glass wool pipe, can be used in the following areas:1) roof insulation, cold protection, sound-absorbing materials; 2) building exterior wall insulation and cold protection; 3) entertainment places, theaters, television stations, radio stations, laboratories, sound absorption treatment.
- Q:What are the common thermal insulation materials for thermal conductivity?
- The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.
- Q:What causes breakage of refractory bricks?
- Refractory brick is a non metal mineral products can be used in the high temperature of 1550 DEG C under belongs to a class of inorganic, used in high-temperature furnace lining materials as protection kiln, which causes damage, usually have these points.Furnace temperature is not clear, there is no corresponding choice of refractory bricks.Physical impact, abrasion and erosion cause damageChemical factors, especially chemical industry, should be made of refractory bricks, which should be resistant to penetration and erosionIV: products from the factory when the factory did not pass the quality inspection standards
- Q:What are the specific raw materials for plastic pallets?
- There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
