Production introduction
Non-asbestos micropores Calcium Silicate Board is a new –style white and hard insulated material, which has the characteristics of small bulk density, high strength and low thermal conductivity. It can bear high temperature and corrosion, tools can optional cut them.
The basic material of calcium silicate board is silica and calcium powder, its reforced material is natural woody fibre, then adding a small amount of additives as well as a large amount of water, after reasonable ingredients, heat of mixing rubber, molding steam, curing crystallization and drying processes, then produce the new building material.
Calcium silicate board includes two style, ?high temperature and low temperature . it is used for process equipment , piping and wall because of its thermal insulation and sound-and-fireproof, the fields include electric power, metallurgy, petrification, construction, vessel and etc.
Usage of product:
- Liner heat insulation for preheater, wind pipe, cover of kiln, cooling machine in cement industry.
- Liner heat insulation for electrolyzing cell in nonferrous metal industry.
- Liner heat insulation for heating furnace, soaking pit, annealer, high temperature flue in metallurgy industry.
- Liner heat insulation for heating furnace, ehtylene pyrolyzer, hydrogenation oven and aromatic oven in petroleum industry.
?
Property of product:
- Using temperature is high, whose highest temperature is 1050°C.
- Low heat conductivity , as special microstructure of product, its porosity can reach over 90%, therefore it has excellent property of heat insulation in the whole temperature scope.
- A little unit weight, high specific strength, whose specific strength (compressive strength / unit weight) is the highest in hard thermal insulation product.
- Good durability, after long used, there is no atomization and its heat-insulating property doesn’t lower.
- Easy construction, there is not any harmful materials to people, such as asbesots, sulfur, chlorine and etc.
- Under high temperature, it doesn’t burn, smokeless and tasteless, there is role of corrode retarding to steel.
