Calcium Silicate Board

Calcium Silicate Board

Short Description:

Calcium silicate board, also called asbestos-free calcium silicate board, is a white, hard thermal insulation material.

The raw materials of calcium silicate board are siliceous materials (quartz powder, diatomaceous earth, etc.), calcareous materials (cement, lime, etc.), and reinforcing fibers, which are made through processes such as pulping, blanking, steaming and curing, and surface sanding of lightweight panels.

    Description


    Calcium silicate board, also called asbestos-free calcium silicate board, is a white, hard thermal insulation material.

    The raw materials of calcium silicate board are siliceous materials (quartz powder, diatomaceous earth, etc.), calcareous materials (cement, lime, etc.), and reinforcing fibers, which are made through processes such as pulping, blanking, steaming and curing, and surface sanding of lightweight panels.

    Features

    1. Fire performance

    It is a non-combustible material. In the event of a fire, the board will not burn or produce toxic smoke.

    2. Waterproof performance

    It has good waterproof performance. It can still maintain stable performance in places with high humidity such as toilets and bathrooms without swelling or deformation.

    3. High strength

    It has high strength, and the strength of 6mm thick board greatly exceeds that of 9.5mm thick ordinary gypsum board. The calcium silicate board wall is solid and reliable, not easy to be damaged or broken.

    4. Dimensionally stable

    It is under strict quality control, and the wet expansion and dry shrinkage rate of the board are controlled within the range.

    5. Heat and sound insulation

    It has good thermal insulation performance. The thermal insulation performance of 10mm thick partition wall is obviously better than that of ordinary brick wall, and it also has good sound insulation effect.

    Application
