Introduction of Calcium Carbide:
Calcium carbide is inorganic compounds, white crystal, industrial products are gray black blobs. Its cross section are often purple or gray. When meet water ,it will react violently, generate acetylene, and gives off heat. Calcium carbide is an important basic chemical raw materials, mainly used for producing acetylene gas.Also used in organic synthesis, oxyacetylene welding and so on.
Calcium Carbide Stone Applications:
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%).
Packing: in 50kgs/100kgs iron drum.
General Specification
Specification | Superfine Grade | First Grade | Second Grade |
Gas yield(L/kg)(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 |
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.
Quality Control
