Calcium silicate board (English: calcium silicate) as a new type of green environmental protection building materials,
besides has the function of the traditional plasterboard, has more superior fire resistance and resistant to moisture,
the advantages of long service life, a lot of application in the engineering construction industry ceiling smallpox and partition,
liner, billboards in home decoration, furniture plate, ship plate of storehouse, warehouse shed board, network and tunnel
engineering indoor floor wall plate.
Calcium silicate board is composed of siliceous materials (mainly composition is SiO2, such as quartz powder, fly ash, diatomite, etc.),
calcium material (ingredient is CaO, such as lime, calcium carbide, cement, etc.) mud, enhance fiber, additives according to certain proportion coordination,
the copy or moulding, autoclaved curing processes such as made of a new type of inorganic building materials.Because of its high strength, light weight,
and has a good performance can be processed and incombustible, so widely used in Marine bulkhead, ceiling, and construction of nonbearing wall,
there is a requirement for fire prevention and other places.Calcium silicate board insulation with calcium silicate board and decorate with calcium silicate board.
- Q: What are the production methods of calcium silicate board material?
- Calcium silicate (microporous calcium silicate) material and calcium silicate board are produced by static steaming method, dynamic hydrothermal synthesis method and two reaction method.
- Q: What is the maximum temperature at which the glass is cured?
- Glass is softened at a temperature of 600 degrees. When making glass, but ordinary alcohol lamp is enough to soften it. Glass is not crystal. The softening point of lead glass is 500 degrees. The main component of ordinary glass is CaO: Na2O: 6SiO2, which can be softened by fire. In addition to the ordinary glass, glass wire, alcohol burner 1000 degree glass has no definite melting point and freezing point, in softening products can be made into any shape, so there is no fixed melting point, clarification, fluoride special glass based raw materials, slightly higher than 1200 DEG C melting, but the softening point, as well as borate, limestone, mixed melt in glass kiln.
- Q: What's the difference between white carbon and carbon black? Can they be replaced?
- White carbon black in color rubber products instead of carbon black reinforcing, meet the needs of the white or translucent product. Anti aging performance of silica with strong adhesion force, tearing resistance and heat, so the black rubber products can replace part of the carbon black, in order to obtain high quality rubber products, such as off-road tires, engineering tire, radial tire.
- Q: What are the high temperature resistant insulation materials at 400?
- According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.
- Q: What are the three major effects of fly ash in concrete?
- Fly ash "micro aggregate effect" in the fly ash particle size is very small beads and debris in cement can be the equivalent of unhydrated cement grains, tiny beads equivalent to nano material and lively, can significantly improve and enhance the structural strength of concrete and improve the homogeneity of products, and compactness.
- 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 is the best price for the use of calcium silicate ceiling?
- The price of each place and labor costs are not the same, here in Heilongjiang labor costs about 18---20 yuan per square meter, plus keel, hanger, calcium silicate board of about 45----50 yuan per square meter.
- Q: What is the main role of fly ash added in concrete products?
- The rational use of fly ash in concrete, not only can replace part of cement, reduce the construction cost, but also because of its unique properties can be effectively used for the various requirements of the use of concrete, improve and enhance the performance of concrete.
- Q: Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it
- The market is generally understood, but in fact, Eterpan belongs to Guangzhou eternit limited production of the 100 year history of eternit brand board, because the cement product is Belgium hetet group invention.
- 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.
