Description

Quick Details CAS No.: ******7 MF: CaC2 Place of Origin: Inner Mongolia China (Mainland) Grade Standard: Industrial Grade Purity: *8% Appearance: grey,purple Brand Name: Jinyuan Colour: grey,purple Calcium carbide;Gas yield:**5L/kg min In *0/**0/**0/**0kg drum Size:**3,**4,**7,***5,****5,****0,****0,*****0,*****0,******0mm 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 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.
