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 Carbide Stone Applications:
1 )The main raw material for producing acetylene welding gas. 2) Cutting and welding for metal material. 3) To synthesize polyvinyl chloride(PVC). 4) Fruit catalyst.5) Deoxidization and desulphurization. If you have other problems and please contact with us!
