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%).

Cautions during transportation: 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. 50kgs or 100kgs per iron drum
