Calcium silicate board is a new type of lightweight multi-purpose board, which is made of silicon materials (diatomite, bentonite, quartz powder, etc.), calcium materials (slaked lime, carbide slag), reinforcing fibers (asbestos, glass fiber), etc. The calcium silicate board is made by pulping, cultivation, steaming, surface sanding, and other processes. It has a wide range of uses and can be used as non-load-bearing partition walls and ceiling boards, and can also be used to make air ducts and lining boards as well as the compartment panels and partition panels of vehicles and ships, and other places with heat insulation requirements.
