Calcium Carbide 75-20-7

Product Description

1. It is called calcium carbide( CaC2).  It is a hard lump and the cross section is dark grey or brown.

2. It  is lumpy substance, its surface is a little deep gray, has slight nasty smell.

3. It can produce acetylene gas when met water, it can burn when meets fire.

4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is      2.3% - 81%).

FAQ

Q: How can you guarantee the quality  

A: We will take a lot of sampling testing second time during carbide processing to ensure products with good gas yield. 

We often do air pressure testing to drums, ensure carbide drums seals tight and safety.

Different sizes stored separately to avoid size mixing.

We will take sampling test again before goods loading, ensures loaded goods with correct weight, sizes, gas yield and quantity.

Our carbide Production is based on Chinese National Standard: GB10665-2004.


Q: What is the gas yield

A: Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm  is 295L/KG.

The relationship between the gas yield and calcium carbide is as following.
