Silica-calcium board, also known as gypsum composite board, is a multi-element material, generally composed of natural gypsum powder, white cement, glue, and glass fiber. Calcium silicate board has the properties of fireproof, moisture-proof, sound insulation and heat insulation. It can attract water molecules in the air when the indoor air is humid. When the air is dry, it can release water molecules, which can appropriately adjust the indoor dryness and humidity to increase comfort.

The calcium silicate board is mainly composed of calcium silicate, with siliceous materials (diatomite, bentonite, quartz powder, etc.), calcareous materials, reinforcing fibers, etc. as the main raw materials, after pulping, blanking, steaming, and surface sanding Lightweight panels made by other processes.

Calcium silicate board has the advantages of light weight, high strength, moisture-proof, anti-corrosion, and fire-proof. Another notable feature is that it is easy to reprocess, unlike gypsum board, which is easy to powder and chip. As a gypsum material, compared with gypsum board, calcium silicate board retains the beauty of gypsum board in appearance; the weight is much lower than gypsum board, and the strength is much higher than that of gypsum board; completely changed The Achilles’ heel of gypsum board deformation due to dampness has prolonged the service life of the material several times; it is also better than gypsum board in terms of sound absorption, heat preservation and heat insulation, but lower than the ceiling made of rock wool.
