Product Description

Calcium Carbide

Standard:GB10665-1997

Specification:

use:

(1) Acetylene formed by the reaction of calcium carbide with water can synthesize many organic compounds. For example: synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; acetylene-oxygen flame is widely used in the welding and cutting of metals.

(2) When the powdered calcium carbide and nitrogen are heated, the reaction forms calcium cyanamide, that is, lime nitrogen, and the cyanide melt formed by reacting the heated lime nitrogen with the salt is used in the gold mining and non-ferrous metal industries.

(3) The calcium carbide itself can be used as a desulfurizing agent for the steel industry.

(4) Production of polyvinyl chloride (PVC), calcium carbide production of polyvinyl chloride using calcium carbide (calcium carbide CaC2), water formation of acetylene (C2H2), synthesis of acetylene and hydrogen chloride (HCl) to produce vinyl chloride monomer (CH2CHCl) And a chemical reaction method for producing vinyl chloride-[CH CHCI]n by vinyl chloride by polymerization.
