Characteristics of high-density calcium silicate board：
The density of high-density calcium silicate board is between 350 and 400kg/m³. Compared with ordinary calcium silicate boards, high-density calcium silicate boards have higher strength, better insulation performance and longer service life. Due to their excellent properties, high-density calcium silicate boards are widely used in industries such as cement, metallurgy, petrochemicals, power and ceramics.

Advantages of high-density calcium silicate board：
- High-density calcium silicate board has higher density and greater strength, which is convenient for cutting during construction, reducing the loss of construction and saving costs.
- High-density calcium silicate boards have high strength, higher heat resistance and a longer service life.
- High-density calcium silicate board has a higher flexural strength, does not deform under long-term heating, and supports and protects the stability of the refractory furnace.
Production process of high-density calcium silicate board manufacturers：
The main raw materials of high-density calcium silicate board are calcium oxide and quartz sand. After being ground into powder, impurities are filtered to ensure the composition. Then, reinforcing fibers are added. After successful reaction in the reactor, it is injected into the mold and pressed into shape. Finally, it is dried in a tunnel cellar to ensure strength and toughness.
