High Strength Calcium Silicate Board

Calcium silicate board, also known as gypsum composite board, is a multi-component material, generally composed of natural gypsum powder, white cement, glue and glass fiber. The 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 properly adjust the indoor dryness, humidity and comfort. ....

The 1100C grade calcium silicate board is made of silica fume, quartz and lime as raw materials. It is dynamically hydrothermally synthesized and strengthened with glass fiber and pulp. The addition of amorphous silica fume fills the between the xonotlite particles. The gaps increase the refractory temperature and are mainly used for thermal insulation of industrial furnaces.
