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.Silicon plasterboard is building gypsum as
main raw materials made of a material.It is a kind of light weight, high strength, thickness thin, easy processing and sound insulation better
building materials, thermal insulation and fire prevention performance is one of the current focus on development of new light plate.
Plasterboard has been widely used in homes, offices, shops, hotels and industrial buildings and other structures within the partition wall,
wall cladding panels (instead of wall plaster layer), ceiling, sound-absorbing board, ground base plate and all kinds of decorative plate.Plasterboard plasterboard plasterboard of face (divided into general (common),
fiber plasterboard, gypsum decorative explain) it with gypsum as main material, add fiber, bonding agent, modification agent, by mixing pressing and
drying.Have fire prevention, sound insulation, heat insulation, light weight, high strength, low shrinkage rate, etc and good stability, not aging, insect-resistant eat by moth, nail, saw, planer, available methods of construction.Acid calcium thermal insulation board points with calcium silicate board and decorate with calcium silicate board.
- Q:Calcium silicate board white ICI belongs to wood surface paint?
- No, it isn't。Calcium silicate board material properties should be comparable with cement products, usually referred to as cement board is actually calcium silicate board.
- 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:What is the maximum temperature at which the glass is cured?
- The softening point of quartz glass is 1600 degrees, it is sodium phosphate and phosphate. Gas burner 1300 degrees, after homogenization processing, after annealing treatment of glass products.
- Q:Eterpan and yinte in what is the difference?
- Calcium silicate board:Calcium silicate board is mainly inorganic mineral fiber or cellulose fiber and other loose short fiber materials with siliceous and calcareous materials as the main cementing material, pulping, molding, in high temperature and high pressure saturated steam curing acceleration, sheet formation of calcium silicate gel made.Calcium silicate board is a new type of building and industrial plate with excellent properties. Its products are fireproof, moisture-proof, soundproof, moth resistant and durable. It is an ideal decorative board for ceiling and partition. Excellent waterproof performance, just can prevent the home improvement for a long time damp deformation, especially in the bathroom for a long time in a humid environment, the use of calcium silicate board ceiling is the best choice.
- Q:What are the raw materials of cement products? What's the function?
- Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.
- Q:What are the production methods of calcium silicate board material?
- The synthesis process of dynamic method is carried out under stirring, the synthesis temperature is higher than the static process, and under the compression condition. The dynamic method is simple, no gel chemical order, products made of small capacity, good performance, can obtain high temperature (1000 degrees Celsius) of xonotlite products and ultra light products, but the need for high pressure vessel with stirring device, equipment and process condition requires high energy consumption and investment are higher. At present, this method is adopted abroad.
- 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:What is dew point of thermal insulation material?
- The heat insulation lining has the characteristics of low thermal conductivity, small density, high flexibility, fire prevention, waterproof, etc..Light weight, 10 96kg/m3, 20kg/m3 following mat, 24 48kg/m3 as in hard, 48 96kg/m3 as core, which 48kg/m can fand a softening point of the ceiling, 500 degrees C, 300 degrees C insulation, the larger the amount, k=0.9.Calcium silicate insulation product was successfully developed in 70s. It has the characteristics of high compressive strength, small thermal conductivity, convenient construction and repeated use. It has been widely used in power systems.Most of the domestic universal small workshop production, have been imported from the United States after the four production lines, advanced technology, instant rejection speed fiber, dry needle felt, stable quality, high temperature 800 to 1250 DEG C.Features: acidity derivative of more than 2, high temperature resistant, general chemical pipe 1000 degrees C more, must use this material. The temperature is about 2000 C.
- 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 heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!
- Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.
