1, production progressCalcium silicate, 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 a new thermal insulation material 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.2.
