Calcium silicate board using silicon and calcium as the main material, with Kun pressure, pressure performance of technology, after autoclaved curing, surface polishing processing, generation dominated the mullite (C5S6H5) crystal structure of silicate calcium board. With high temperature and high pressure steam raising, drying processing production of decorative plate. So it has light weight, high strength, fire, smoke, waterproof, mouldproof, moistureproof, sound insulation, heat insulation, not deformation, do not break down the excellent characteristics, lining board, composite wall panels, insulation materials, roofing laying site for building the wall, wall panels, ceiling panels, curtain wall. Widely used in civil and industrial buildings. Can be used in the construction of floor, wall panels, wall panels, ceiling panels, wall panels, composite wall panels, insulation materials, roofing and other parts of the laying.
