Industrial Calcium Carbide CaC2

Details:

1.Gas yield 285,295,305kg/L

2.Size:0-2mm,2-4mm,4-7mm,7-15mm etc

3.Calcium carbide grey or black solid

4.carbideindustrial grade

5.calciumacetylide285,295,305kg/L

Character:

Industrial products is gray, snuff color or black solid, contain higher of calcium carbide is purple. New fracture of calcium carbide has luster, reveal in the air to lose lustre show offwhite because of the calcium carbide imbibe moisture. Relative density 2.22 (18 centigrade). Industrial product calcium carbide content 80%. Melting point 2300 centigrade. Can conduct electricity, the higher purity, the higher conduct electricity. Chemical property is very lively, at the appropriate temperature can reaction with a lot of gas, solution. Touch with water drastic decompound and bring acetylene and calcium hydroxide, disengaging large numbers of heat. Has drastic chemical reaction with chlorine, hydrogen chloride, sulfur, phosphorus, alcohol etc. At high temperature.

Application:

1)Calcium Carbide is used to produce acetylene gas. calcium carbide and water reaction generated acetylene can synthesis of many organic compounds. such as: synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; At the same time acetylene oxygen flame is widely used in metal welding and cutting.

2) When heating powdered calcium carbide and nitrogen, it produce calcium cyanamide, namely lime nitrogen.heating lime nitrogen and salt generated cyanide solution used in gold mining and nonferrous metal industry.

3)Calcium carbide can be used as desulfurization agent in the Iron and Steel Industry.

4) Manufacture polyvinyl chloride (PVC),
