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 kind of insulation material can withstand 350-600 degrees of high temperature?
- Suggest that you refer to the above two data to choose from, select only from the temperature, you can use
- 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 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: Asbestos free calcium silicate board there is a crack in the kettle, what is the reason?
- Calcium silicate slab blank (blank off off phenomenon is not forming tube adhesion fingerboard blank above)There are two reasons: one is the blank off the vacuum negative pressure is too large, the blank water is too low, low viscosity; two is felt blocked, the billet made worse.The solution is to reduce the negative pressure, strengthen the cloth washing.
- Q: What are the high temperature resistant insulation materials at 400?
- Foam heat insulation material mainly includes two categories: polymer foam type insulation material and foam asbestos insulation material. Polymer foam heat insulation material has the advantages of small absorption rate, stable heat preservation effect, low thermal conductivity, no dust flying in construction, easy construction, and so on. It is in the period of popularization and application. Foam asbestos thermal insulation material has the characteristics of small density, good thermal insulation and convenient construction, and its popularization and development is relatively stable, and the application effect is better. But at the same time there are some defects: for example, foam cotton is easy to damp, immersed in water easily dissolved, elastic recovery coefficient is small, can not contact the flame and in the wall pipe parts use.
- Q: The ceiling of calcium silicate board and mineral wool board which is good
- Calcium silicate board with fire prevention, moistureproof, sound insulation, thermal insulation, indoor air in wet conditions can attract water molecules in air, air drying, and the release of water molecules, can adjust the indoor humidity, dry, increase comfort.Natural gypsum products and special fireproof material, the flame can produce endothermic reaction, at the same time, the release of water molecules to prevent the fire from spreading, and does not produce any toxic decomposition, corrosive and choking gas, will not produce any smoke or combustibles.Mineral wool board is mineral fiber cotton as raw material, the biggest characteristic is to have good sound absorption and heat insulation effect.
- Q: Cement is not silicate products
- There are different kinds of cement: silicate series, aluminate series, sulphoaluminate series, sulfur ferrite system, etc.
- Q: What's the use of white portland cement?
- All the raw meal with the proper components up to the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material, called white portland cement (the white cement).When grinding cement, allow limestone not to exceed 5% of the cement weight.Note: cement is allowed to be added to the grinding mill without damaging the cement properties. The amount of cement added shall not exceed 1% of the cement weight. The addition of additional substance must be tested and reported to the Ministry of construction materials for approval.
- Q: What are the raw materials of cement products? What's the function?
- Cement has a great influence on the properties of concrete. The kinds and quantities of cement containing minerals and the fineness of cement will affect the quality of cement products. The calcium silicate three in cement is an important factor in the coagulation of cement products. The reaction between three calcium silicate and water leads to the production of hydrated calcium silicate, and the hydrated calcium silicate gel acts as a cementing agent for aggregate and aggregate in concrete.
- Q: What's the difference between white cement and ordinary cement?
- The main chemical composition of Portland cement clinker is calcium oxide, silica, alumina and iron oxide. Calcium oxide mainly derived from calcareous raw materials, such as limestone, chalk, marl; alumina and silica from aluminum silicate containing substances, such as clay, blast furnace slag and fly ash; iron oxide is used in sulfuric acid production of sulfur iron slag. For the content of calcium oxide production of Portland cement lime materials in 52%; silicon oxide content of clay in raw materials up to about 57%, the alumina content is less than 20%. In order to reduce the calcination temperature and to produce part of the melt during calcination, a small amount of iron oxide is often added. Of raw materials but also control the content of alkali and Magnesium Oxide, Magnesium Oxide is content in the cement clinker should be less than 5%, total alkalinity (Na2O+K2O) for general cement should be less than 1.2% of low alkali cement should be less than 0.6%.
