Calcium Carbide Testing
4 year ago
Calcium Carbide is lumpy substance,Cemented Carbide ,Pvc Resin , Carbide Calcium surface is a little deep gray, Minerals & Metallurgy. has slight nasty smell. Calcium Carbide 50-80mm can produce acetylene gas when met water Boric Acid Flakes , Carbide Calcium can burn when meets fire Titanium Dioxide. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).
