• DESCRIPTION

Calcium silicate board is made of loose short fiber such as inorganic mineral fiber or cellulose fiber as reinforcement material, silica-calcium material as the main cementing material, through pulping, molding, accelerated curing reaction in high temperature and high pressure saturated steam to form calcium silicate gel and made of board. It is a new type of building and industrial board with excellent performance of fireproof, moisture-proof, sound-proof, moth-proof and durable, and it is an ideal decorative board for ceiling and partition.

• PROPERTIES
