Perforated calcium silicate board, as a popular star in the construction engineering industry, is made of siliceous raw materials (such as calcium ash, coal ash, attapulgite, etc.), calcium raw materials (such as lime powder, Calcium carbide mud, concrete, etc.) as the basic raw materials, wood pulp chemical fiber as the reinforcement fiber, and through a series of technological processes such as a certain proportion of mediation, papermaking, vacuum molding, etc. It has the characteristics of high strength, light weight, fire safety, flame retardancy, and durability.
In terms of industry standards, there is no requirement for a fire resistance rating of perforated calcium silicate board, only one fire resistance is implemented according to the standard. In other words, industry standards require that the fire resistance of calcium silicate board be met. Because most of the raw materials used for perforated calcium silicate boards are inorganic materials, most of the products meet the standards. With the continuous improvement of fire protection requirements of Modern architecture, some large engineering buildings have stronger regulations on the raw materials used than industry standards. Baolin board calcium silicate board produced by our company is a high-quality decorative building material that has been tested for more than 4 hours or more than 2 hours according to industry standards. This also depends on the differences in requirements made by the construction engineering design based on the different main uses of wood.
