High temperature resistant calcium silicate board is an inorganic insulation material mainly composed of silicon and calcium materials, made through high-temperature and high-pressure processes. It has the characteristics of high temperature resistance, non flammability, and high compressive strength, and is widely used in industrial equipment, construction and other fields. Using quartz sand, diatomaceous earth (siliceous material), cement, and lime (calcareous material) as raw materials, reinforcing fibers (such as cellulose fibers or mineral fibers) are added, and after pulping and molding, they are cured in high temperature and high pressure steam to form calcium silicate cementitious material.
