The full name of calcium silicate board is fiber reinforced calcium silicate board. It is made of siliceous material (diatomite, bentonite, quartz powder, etc.), calcareous material, reinforced fiber, etc. as the main raw materials, it is made of light board through pulping, green forming, steam curing, surface sanding and other processes. Calcium silicate board has the advantages of light weight, high strength, moisture resistance, corrosion prevention and fire prevention. Another remarkable feature is that it is easy to be reprocessed. Unlike gypsum board, it is easy to be broken into powder and mineral wool board can not be reprocessed. Mineral wool board is composed of mineral wool, adhesive, pulp and perlite by slag rotating at high temperature, high pressure and high speed, removing impurities and washing. Mineral wool board has similar characteristics of calcium silicate board, but its sound insulation performance is worse than gypsum board and calcium silicate board. It can not be waterproof, easy to deform and turn yellow with time. The mineral wool dust particles of mineral wool board are easy to inhale into human body and are highly carcinogenic. To sum up, the high strength waterproof calcium silicate board is a new type of waterproof board. It changes the defects of gypsum board, which is not waterproof, moldy and easy to deform. It has the advantages of sound absorption, fire prevention, waterproof, mildew proof, heat insulation and light weight. It is not warped and deformed in the air relative humidity of 90%. It is widely used in hotels, shopping malls and offices Building, conference center, hospital and other large-scale cultural places are excellent. Smallpox is made of silicon calcium board ceiling, which is different from mineral wool board, and has no dust particles. The gypsum vapor permeability and pH value of calcium silicate board are also known as "near skin" building materials, similar to the chemical physical properties of human skin. Gypsum is also a cosmetic facial mask material. There will be no water and damp in the ceiling, so molds can not grow. The results show that: the pure gypsum in the western medicine Pharmacopoeia as a pharmaceutical base material, in traditional Chinese medicine is a good medicine to clear fire. "Shennong materia medica classic" and "Kaibao Materia Medica" record: gypsum, spicy, sweet, cold, return to the lung and stomach meridian, can nourish yin, clear heat, eliminate vexation and thirst, activate blood circulation to relieve pain, astringent and generate muscle. This fully shows that gypsum containing building materials are hygienic, but also a very comprehensive green building materials, fully in line with the policy of sustainable development. Because of this, the application of calcium silicate board extends from southeast coast to inland, from big cities to small and medium-sized cities.

It can be predicted that calcium silicate board will become a well-known environmental protection building decoration board in China in the next few years.
