Acetylene Stone Calcium Carbide Cac2, Grey Color, 20mm Cas No: 75-20-7

The product uses high-quality gas-solid calcium carbide, not coke. In special heat treatment, the porosity is very small, the outflow rate is low, and long service life. Coffee machines are easy to operate. The production process of acetylene stone is from the gasification of waste gas from iron and steel processing factories. It can be made by compressed air carbon powder method and spray methods. Calcium carbide is made of stone, generally grey in color, with high hardness and good toughness. The high temperature of this product can create acetylene gas with relatively high efficiency by decomposing water. Different types of calcium carbide are widely used in the petroleum industry, chemical industry, steel and non-ferrous metal industry, electric power industry, and the manufacture of high-aluminum ceramics, etc.
