gas yield:280-290l/kg,295l/kg,305l/k

packing:in 100kg or 50kg new iron drum and sealed with Nitrogen gas.

Property:   

Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18), melting point is 2300, the product can absorb water in the air and conduct electricity. They higher its purity is, the easier it conducts, it dissolves in water, turns into acetylene and calcium hydroxide and release heat.

Process:

The production methods of aerobic hot and heating method. General electric heating method is used more production calcium carbide, namely the quick lime and carbon materials (coke, anthracite or petroleum coke) in calcium carbide furnace, rely on the arc high temperature melting reaction and generate calcium carbide.

Package:in 50kg,100kg or 200kg net new iron drum and sealed with Nitrogen gas ,one container can load 22.5 tons

Specification:

Application:  

1 )The main raw material for producing acetylene gas.

2) Cutting and welding for metal material.

3) To synthesize polyvinyl chloride(PVC).

4) Fruit catalyst.
