Low-Ash Calcium Carbide 6-20mm for Acetylene Black Production, Carbon Reinforcement Applications

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.

Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm is 295L/KG. The relationshipbetweenthe gasyieldandcalcium carbideis as following. CaC2(%) 63.14 68.52 72.54 73.89 75.2 76.57 77.91 80.6 Gas Yield(L/Kg) 235 255 270 275 280 285 290 300

It is usually within 20 days after receiving the deposit or original L/C.

It is the main raw material for producing acetylene gas, used for cutting and welding metal, synthesizing PVC, as a fruit catalyst, and as a desulfurizer in the steel industry.

We offer 50KG and 100KG drums. Options include packaging with pallets or without pallets, with specific weight and volume configurations for 20ft containers.
