Calcium carbide, best quality ;Gas yield: **5L/kg min In *0/**0kg drum; Size: **7mm, ***5mm, ****5mm.****0mm, ****0mm, *****0mm Applicantion: This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - *1%).

Packing *0kg or **0kg iron drum Cautions during transportion: The packing must be kept in good condition and the goods should be stored in a dry, cool and ventilated ***** should be separate from the cargo can burn and ***** should avoid meeting water and ***** 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.
