Introduction of Calcium Carbide:
Calcium carbide is a chemical compound with the chemical formula of CaC2. The material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its main use industrially is in the production of acetylene and calcium cyanamide.
Usage:
Calcium carbide is an important basic material in organic synthesis industry, Acetylene obtanied from calcium carbide is raw material to make ethylene, chloroprene rubber, calcium cyanamide, acetic acd, acetaldehydr, ethylacetate, cyanide acetate, dicyandiamide, acetone, octanol, trichloride ethylene etc. Also used as desulfurizer and dehydrant of steel and for cutting and welding metals.

Cautions during transportion:
The packing must be kept in good condition and the goods should be stored in a dry, cool and ventilated place.
It should be separate from the cargo can burn and acid.
It should avoid meeting water and moisture.
It should give off the acetylene in iron drum before storing in warehouse.
Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
