formula : C2CaMW : 64.10CAS, introductory-20-7
Acetylene stonesnature : industrial gray, tan or black solid, with a higher calcium carbide was purple. Calcium carbide fracture surfaces of a new luster, exposed in the air by absorbing moisture was dull gray. General industrial products containing calcium carbide 80%. Melting point 2300 ° C and relative density (18 / 4 ° C) 2.22. Can conductive, the higher the purity, the better conductivity. The chemical nature very lively and heated with water decomposition of acetylene gas, and calcium hydroxide, and release a lot of heat. With chlorine, hydrogen chloride, sulfur, phosphorus and ethanol at high temperature can occur intense chemical reactions. Preparation : EAF reduction is the production of calcium carbide industry the only way. This method back in 1895 the United States to achieve industrialized production and production of high-temperature operation, more dust, power consumption, technology improvement of operating conditions will improve, reduce heat loss and improve the recovery efficiency of carbon monoxide, more closed and larger carbide furnace. Will Coke and lime crushed by mixing ratio of homogeneous to join closed carbide furnace, ohmic heating, in 2000-2200 ° Cfor reduction reaction, generating molten calcium carbide, electricity flows from the furnace cooling stone, broken packaging. Kg / ton coke (fixed carbon 84%) 550 Limestone (CaO92%) 840 30 -- PASTE 3200 (degrees / ton) purposes : calcium carbide for chemical production accounted for about 60% and the remaining 40% for metal welding and cutting. Calcium carbide can produce raw materials for a series of chemical products such as PVC resin, polyvinyl alcohol, vinyl acetate, chloroprene rubber, butyl alcohol, octanol, 3 cyanide ethylene, ethylene four cyanide, acetaldehyde, acetylene black, lime nitrogen. While the amount is the largest production of PVC resin, chemical or stone electricity consumption by 60%. Calcium carbide powder is irritating, can damage the skin and the respiratory system.
