Calcium silica board introduction
Calcium silicate board is take high grade siliceous and calcareous materials, reinforcing fiber as the main raw materials, by a certain percentage mixing, made through a series of processes. Calcium silicate board is an asbestos-free thermal insulation product, which is fireproof, thermal insulation, mothproof and preventing mildew.
Calcium silica board features
The product with good toughness and strength appears flattening and the ceramic material distributes uniformity, it also has excellent thermal insulation performance.
Heating is not inflated, light, construction convenient, free shear and bending, is the ideal energy-efficient insulation materials of a furnace, piping and other equipment
