Calcium silicate board is made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials and silicon-calcium materials as main cementing materials. After pulping, molding and accelerating curing reaction in saturated steam at high temperature and high pressure, calcium silicate gel is formed. It is a new type of building and industrial plate with excellent performance. Its products are fireproof, moisture-proof, sound-proof, moth-proof and durable. It is an ideal decorative board for ceilings and partitions.
At present, there are about 50 calcium silicate board production lines in China, mainly distributed in Guangdong, Hebei, Shandong, Zhejiang, Jiangsu, Jiangxi and other places. At present, there are more than 10 calcium silicate board manufacturers in Guangdong, and the annual growth rate is more than 30%.
