Product Description

Calcium carbide stone supplier gas yield welding calcium carbide 80-100 mm

Propertics
Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18°C), melting point is 2300°C, 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 releases heat.
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% - 81%).
Specification

Specification	Superfine Grade	First Grade	Second Grade
Gas yield(L/kg)≥	305	295-305	285-295
PH3 content in acetylene (PH3%) ≤	0.06	0.08	0.08
H2S content in acetylene (H2S%) ≤	0.1	0.1	0.1

 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.
Package
1. 50kg packing with new iron drum 
2. 100kg packing with new iron drum 
3. 200kg packing with new iron drum

Cautions During Transportation

The product is transported in containers. The packing must be kept in gonnd condition and 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 meet water and moisture. It should give off the Acetylene in iron drum before storing in waechouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark lead to explosion. The fine expired in 6-12 months.
