Calcium silicate board and gypsum board are two completely different materials, but because their usages are similar, they are often got confused.
Gypsum plaster board mainly use plaster as the main raw material. The surface is a special paper for protection. After processing, the plaster board has characteristics of light weight, high-strength, thermal insulation, simple construction and so on.
Calcium silicate board is mainly made of siliceous materials and calcium materials through a variety of production process systems. It has good characteristics of fire proof, waterproof, lightweight, longer life, thermal insulation, and high density. The fireproof and waterproof performances of gypsum board are relatively low, so it is being replaced by calcium silicate board. Calcium Silicate Board is one of the most important products in the future development of light weighted high strength wall partition system.
Calcium silicate board as a new environmental friendly building materials, beside containing all the functions of the traditional gypsum board, it also has superior performances in fire proof and resistance to moisture environment. In addition, it has the advantage of longer usage life. As a result, a large number of industrial and commercial projects use calcium silicate board for the construction of ceiling and partition, advertisement billboard, ship’s compartment board, the roof of warehouse, tunnels and other indoor projects of the wall.
Calcium silicate board is made of siliceous materials (mainly composed of SiO2, such as quartz powder, coal ash, diatomite, etc.), calcium materials (mainly CaO, such as lime, calcium carbide mud, cement, etc.), reinforcied fibers, and other additives. According to a certain proportion of various compounds, use advanced producing technology of molding, pressure, high-temperature steaming and other special technical processing to made calcium silicate board.
Thus, compared to gypsum board, calcium silicate board has a larger advantage of waterproof, fireproof, thermal insulation, sound insulation, higher strength, resistance of corrosion and longer usage life. Along with the technical progress in many countries, and the development of home decoration material, calcium silicate board has replaced gypsum board in many areas.
