Used in the production of acetylene gas, polyvinyl chloride, lime nitrogen, dicyandiamide, iron and steel desulfurizer, etc., used in electronics industry, teaching reagents. Calcium carbide is used for chemical production accounts for about 60%, and the remaining 40% is used for metal welding and cutting. Using calcium carbide as raw material can produce a series of chemical products, such as PVC resin, polyvinyl alcohol, vinyl acetate, neoprene rubber, butanol, octanol, tricyanoethylene, tetracyanoethylene, acetaldehyde, acetylene carbon black, lime nitrogen, etc.

1. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire. 4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

Calcium chloride is an inorganic salt, which exists as solid or liquid. solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. with different crystallized water contents, it can be dehydrate or anhydrous. liquid calcium chloride is a colorless, clear solution. as calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature, it is widely used in snow & ice melting, dust control, oil & gas drilling, moisture-absorbing According to the content of crystal water in calcium chloride: (1). Calcium chloride dehydrate a. Calcium chloride flake dehydrate 74%min; 77%min; b. Calcium chloride granule/pellet dehydrate 74%min; 77%min (2). Calcium chloride anhydrous a. Calcium chloride powder anhydrous 94% min b. Calcium chloride pellets anhydrous 94%-97% min according to grade: (1). Calcium chloride industrial grade (2). Calcium chloride food grade
