High Alumina Ceramic Rollers

Q: What kind of insulation material can withstand 350-600 degrees of high temperature?: GB 50264-97 code for design of thermal insulation engineering for industrial equipment and pipelines98T901 cold storage Atlas of piping and equipment

Q: Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?: Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.

Q: What are the three major effects of fly ash in concrete?: The "activity effect" of fly ash is also known as the pozzolanic effect because it contains a large amount of active SiO and AI. With Ca (OH) and other basic chemical reactions, C-S-H, hydrated calcium aluminate cementitious material, the fly ash concrete products and can serve to strengthen the role and blockage of capillary tissue in concrete, improve the corrosion resistance of concrete.

Q: What's the use of white portland cement?: The typical feature of white cement is high whiteness, with bright color, generally used for a variety of architectural decoration materials, painting, sculpture, a typical floor, terrazzo, white cement can be used to produce white and colored concrete, is the largest cement production decoration.

Q: What are the raw materials of cement products? What's the function?: Sand。 Gravel occupies a very large volume in concrete production, reaching 70%~80%. The aggregate surface, structure, adsorption and water content of aggregate should be required. The appropriate amount of sand and gravel can save cement, reduce the cost of concrete production, and improve the strength of concrete.

Q: What's the use of low carbon steel insulated nail hooks for power plants?: Low carbon steel nail insulation (aka: insulation pins) material: low carbon steel wire for power plants or stainless steel wire products: insulation nail. Hook nail is a power plant by mechanical processing of special insulation nail models: nail diameter: 3 mm with 3.5mm with 4 mm with 5 mm with 6 mm etc.

Q: How to make building glue?: An adhesive and a preparation method thereof, according to the proportion of the polyether and polyester resin, and multiple natural plant resin, polystyrene resin, solvent oil and ultraviolet resistant, anti-aging agent in the container, evenly stirring at 20 DEG -30 DEG C into TDI, heating up to 70 DEG -100 DEG 2-5 hours of stirring that uniform to room temperature, adding industrial gasoline diluted into oil, the transparent liquid is liquid, of course, according to the need of color, can also add to the metal paste color. The main feature of the invention is to glue sealing watering Ni bare surface, to set free, waterproof, anti cracking and water conservation effect, while the antirust effect is far more than the anti rust paint several times.

Q: What is dew point of thermal insulation material?: 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 is a building energy-saving materials?: Heat insulation materials and insulation materials collectively referred to as thermal insulation materials.The commonly used thermal insulation material: mineral wool, rock wool, glass wool (in rock, slag as the main raw material, by high temperature melting, made by centrifugal methods such as cotton and thermosetting resin binder insulation products. ) foam plastics and porous polymers, expanded perlite and their products, calcium silicate insulation products, all kinds of composite insulation materials.

Q: What are the exterior walls of the building besides the benzene board and the extruded board?: Calcium silicate insulation insulation materials in 1980s has been recognized as the massive rigid insulation materials in one of the best, which is characterized by low density, high heat resistance, low thermal conductivity, flexural strength, high compressive strength, low shrinkage. But after entering 1990s, the promotion of the use of a downturn, the main reason is that many manufacturers to adopt in order to solve the problem of non asbestos fiber pulp, pulp fiber and not due to high temperature, thus affecting the thermal insulation material of high temperature resistance and increase the breaking rate, and not the economy.
