Q:What are the high temperature resistant insulation materials at 400?
Thermal insulation materials for thermal equipment and pipes are mostly inorganic insulation materials. This kind of material has the characteristics of no decay, no burning, high temperature resistance and so on. For example: asbestos, diatomite, perlite, glass fiber, foam glass concrete, calcium silicate and so on.
Q:What are the production methods of calcium silicate board material?
The two reaction method (also called combined method) is the most complete and easy to obtain process of high temperature, light weight and high strength calcium silicate products and calcium silicate boards, but its disadvantages are long process, high energy consumption and large investment.
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: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: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 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 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 is a building energy-saving materials?
Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.
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:Cement is not silicate products
Usually refers to silicate products with lime (calcium containing materials) and sand, fly ash, slag (siliceous materials), then add a small amount of gypsum, the steam steam curing or steam curing, building products quickly generate Tobey mullite, calcium silicate, hydrated calcium aluminate sulfate and hydrated calcium aluminate such as cementitious materials and production. Such as: autoclaved fly ash (sand), autoclaved aerated concrete, autoclaved fly ash brick, autoclaved sand lime bricks.
