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: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 difference between calcium silicate board and cement fiber board?
Fiber cement pressure plate is cement, fiber and other raw materials, after pulping, molding, thousands of tons of press. Calcium silicate board is made of silica and calcium plus fibrous material after pulping and formed by chemical reaction in high temperature environment. Therefore, the difference between the two is very large, mainly in the following aspects:1, from raw materials, calcium silicate board and fiber cement pressure plate difference is mainly calcium silicate board cement content is little, with sand and fly ash instead of cement.2, fiber cement pressure plate is a physical product, calcium silicate board is a chemical product.3, fiber cement pressure plate has press, calcium silicate board has no press; calcium silicate board has autoclaved Fu, fiber cement pressure plate no..4. The density of the fiber cement pressure plate is higher than that of the calcium silicate board, the density of the fiber cement pressure plate is above 1.5g/cm3, and the density of the calcium silicate board is about 1.2g/cm3.5, fiber cement pressure plate thickness can do 2.5-100mm, calcium silicate board can not do less than 4mm of ultra-thin plates and more than 30mm super thick plate, general calcium silicate board manufacturers can only do 6-12mm thickness.6, the normal production of fiber cement pressure plate color is cement color, calcium silicate board color is white.
Q:What's the difference between white cement and ordinary 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:Calcium silicate board for house ceiling, 6mm or 8mm?
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. Its surface has the effect of knurling and relief, such as star, caterpillar, cross flower, central flower, walnut line, stripe and so on. Mineral wool board can sound and heat insulation, fire prevention, any products do not contain asbestos, harmless to the human body, and has anti sag function.
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:How to make building glue?
Universal type building adhesive and preparation method thereof, which is characterized in that the main components of the building glue: TDI, polyether, polyester, multiple resin, natural plant resin, polystyrene thin ester, solvent oil and ultraviolet resistant, anti-aging agent, component ratio (by weight) of:TDI2%--7%, 3%--8%, polyester polyether 1%--6%, multi resin 6%--15%, natural plant resin 6%--15%, polyphenyl ester 14%--25%, savanna solvent oil 10%--20%, anti UV, anti ageing agent 1%--4%.
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:What is the best price for the use of calcium silicate ceiling?
Water will melt or become yellow, mildew. So if you choose their ceiling, you must first deal with the roof leak. Calcium silicate board with artificial and material prices of about 22 square meters, mainly for office space, and residential corridors and other public places decoration. Integrated ceiling is not afraid of water.
Q:What are the main use of lime?
A rigid inorganic cementitious material consisting mainly of calcium oxide. Lime is made from limestone, dolomite, chalk and shell with high content of calcium carbonate and calcined at 900~1100 DEG C. Lime is one of the earliest cementitious materials used in human life. Lime is widely used in civil engineering and can be used in medicine in our country.
