Product Description
Product name: calcium carbide and best quality calcium carbideProduct name: Calcium CarbideChemical Formula: CaC2HS code:28491000CAS: 75-20-7Appearance:gray solidGas Yield: 295L/KG minSize: 0.3-1mm, 1-4mm, 4-7mm, 4-15mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, 70-100mm, 80-120mmSpecification:4-7mm Gas Yield≥280L/KG, 0.06%≤PH3 content in acetylene max.,0.1%≤H2S content in acetylene max,7-15mm,Gas Yield≥290L/KG, 0.06%≤PH3 content in acetylene max.0.1%≤H2S content in acetylene max.
15-25mm,Gas Yield≥290L/KG, 0.06%≤PH3 content in acetylene max.0.1%≤H2S content in acetylene max. 25-50mm or 50-80mmGas Yield≥295L/KG, 0.06%≤PH3 content in acetylene max.0.1%≤H2S content in acetylene max.
Applicantion: (1)Reacting with water to bring about ethine.(2) Reacting with nitrogen to product lime nitrogen .(3)The desulfurizer in steel industry.Applicantion: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%). Technical specifications and features

11. Packing 50kg or 100kg 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 should be separate from the cargo can burn and should avoid meeting water and 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.
