Characteristic and superiority
Calcium carbide,Also called calcium carbide, acetylene calcium, quarry stone, is an inorganic compound, white crystals, industrial products for the gray-black lumps, cross-section for the purple or gray. Instantaneous reaction with water, the formation of acetylene, and release heat. Calcium carbide is an important basic chemical raw materials, mainly used to produce acetylene gas. Also used for organic synthesis, oxygen and other welding
Application
(1) acetylene and water generated by the reaction of acetylene can be synthesized many organic compounds such as: synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc .; at the same time acetylene flame is widely used in metal welding and cutting.
(2) heating powdered calcium carbide and nitrogen, the reaction to produce calcium cyanamide, that is, lime nitrogen:
Lime nitrogen is an important raw material for the preparation of cyanamide. Heating lime nitrogen and salt reaction generated by the melt used in gold and nonferrous metals industry.
(3) calcium carbide itself can be used in the iron and steel industry desulfurization agent.
(4) the production of polyvinyl chloride (PVC),
(5) the old miners under the mine, the calcium carbide into the tin cans generated by the use of acetylene (C2H2) made of calcium carbide lamp.
