Asbestos-free high temperature resistant calcium silicate products are a kind of high efficiency and energy saving materials, at present, the material has advantages in the application of high temperature field, its excellent thermal insulation, thermal insulation performance has been generally recognized in the industry, it has been widely used in metallurgy, petroleum, light industry, building materials, machinery, electric power and other departments, as tower, tank, furnace, kiln wall insulation, thermal insulation materials. At present, China's mass production of calcium silicate products are tobermolite as the main mineral composition of products, the highest use temperature of 650℃, I call it microporous calcium silicate products. Asbestos-free high temperature resistant calcium silicate products are products composed of hard calcium silicate as the main mineral, and the maximum use temperature is 1050℃. 1050 degree high temperature resistant calcium silicate board has: 1. Good durability, can withstand the continuous heat load within the high temperature limit. 2. Low thermal conductivity and high adiabatic performance throughout the use range. 3. Light weight, high specific strength. 4. Good durability, long-term use without powder phenomenon. 5. Strong construction applicability, with ordinary woodworking tools can be cut products at will. 6. Safe and hygienic use. Free of asbestos, sulfur, chlorine and other toxic substances. 7. Not afraid of wet water, product performance unchanged after drying. 8. Protect high temperature equipment and extend the service life of equipment
