Calcium silicate Insulation board is a new type of board made of siliceous and calcareous materials with a composition content of >90%, through the pulping, moulding, steam-raising, drying, sanding and post-processing, etc., which is a kind of asbestos-free high-performance thermal insulating material with low weight, high strength, low thermal conductivity, high-temperature, corrosion-resistant, cuttable, turntable, etc., being Widely used in electric power, metallurgy, petrochemical, construction, shipbuilding, cement and other industries, boilers, industrial kilns, heat insulation.
In addition to ordinary calcium silicate insulation boards, we also supply high-density calcium silicate boards:
There are generally two common types of high-density calcium silicate boards: glass fiber calcium silicate board (common type) and carbon fiber calcium silicate board (high temperature type), both of which have high compressive strength and a density above 800, but the specific The density can be customized according to customer requirements. N-14 is a glass fiber high-density calcium silicate board, and N-17 is a carbon fiber high-density calcium silicate board. The glass fiber high-density calcium silicate board is the common type in the high-density calcium silicate board, and the carbon fiber is the high-temperature type, which has better thermal shock resistance.
