Microporous Calcium Silicate Insulation Material

-
图片
Calcium silicate, also known as microporous calcium silicate, refers to a porous thermal insulation material made from the CaO-SiO2-H2O ternary system. It is a new type of thermal insulation material. In the CaO-SiO2-H2O system, there are currently 22 known minerals. However, there are only two types of thermal insulation materials widely used in industry, namely Xonotlite and Tobermorite. The chemical formula of the former is close to 6CaO·6SiO₂·HO. The chemical composition of its actual product is as follows: SiO2 46.3%, Al2O3 0.3%, CaO 43.3%, MgO 0.7%, Fe2O3 2.5%, and ignition loss 5.9%. The maximum operating temperature of this product is 1000℃. The chemical formula of Tobermorite is close to 5CaO·6SO₂·5H2O. The chemical composition of an actual product is as follows: SiO2 44.4%, Al2O3 3.7%, CaO 4.7%, MgO 0.6%, Fe2O3 1.8%, and ignition loss 13.8%. Tobermorite has a layered structure, and the interlayer distance of 11.3A is called 11ÁTobermorite, and the interlayer distance of 14Á i...

High-Temperature and Explosion-Proof Corundum High-Strength and Wear-Resistant Castable for Kiln Lining

-
图片
Corundum high-strength wear-resistant refractory castable is a wear-resistant refractory castable formed by high-strength and low-cement combination materials cemented with corundum, silicon carbide and other substances. Corundum is a trigonal crystal mineral with a melting point as high as 2050°C and a thermal expansion coefficient of 8.6*10-6K-1. It is a material with moderate to low thermal shock resistance. The hardness of corundum is 9, which is only lower than diamond and a few synthetic high-hardness minerals. Corundum products have high strength. For example, the compressive strength of alumina ceramics can reach 2000MPa, the flexural strength can reach more than 250MPa, and the hot flexural strength at 1000°C is 150MPa. Therefore, the corundum in the corundum high-strength wear-resistant refractory castable has strong resistance to wear. Corundum high-strength wear-resistant refractory castable Corundum high-strength and wear-resistant refractory castables are mainly used at ...
