Calcium silicate is a type of micro-porous structure rigid insulation materials, uses silicon oxide, calcium oxide, and the reinforcing fibers as its main raw materials, made through mixing, heating, gelling, molding, auto calving and drying processes. It is known as the stability in different temperature, asbestos-free and high thermal insulation properties at 650℃,1050℃.
Characteristic
- High strength: the strongest one among the inorganic thermal insulation materials with the similar density.
- Thermal-resistance: Non-deformation at the temperature used.
- Thermal insulation: lower thermal conductivity than other hard mass thermal insulation material.
- .Asbestos – free.
Applications
Calcium silicate are recommended as thermal insulation in stove, cave dwelling of steel mill, petrochemical, ceramics ,glass, cement industries as well as other various ancillary heating equipment.
