Calcium silicate is a new style thermal insulaiton material with white and smooth surface, it is 100% non-asbestos, non-toxic, non hazardous substances, having excellent fireproof and waterproof performance, and the service life is very long.
With monox (quartz sand, powder, silicon, diatomaceous earth, etc.), calcium oxide (or slaked lime, carbide slag, etc.) and reinforced fiber (mineral wool, glass fiber, etc.) as main raw material, is made through rabbling, heating, gelling, molding,steaming and pressing, and rigidification, and at last drying. It is a light-weight and multiporous thermal insulation material.
Application:
Our products are widely used as furnace backup insulation in steel, petrochemical, ceramic, cement & glass industry or fire protection in building construction.
