CAS : 75-20-7 HS Code : 2849100000 Packing : Grey/Black/Green/Blue/Yellow Iron Drums 305/ 295 /285L/Kg Application Other name: calcium acetylide, acetylene calcium carbide, GA Shape: white crystal, industrial products for black lumps, purple or grey section Partical size avaliable: 2-4mm, 4-7mm,7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-120mm Gas yield: 210L/KG,230L/KG,260L/KG, 295L/KG according different partical size Physical and chemical characteristics: the ore is a solid brown or black solid, pure white crystal products(including CaC2 is purple).Density of 2.22g/cubic centimeter,melting point of 2300 degrees C(with CaC2 content),in case of water immediately produce a violent reaction, the formation of acetylene, and the release of heat, calcium carbide content of different melting point will also change. Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.
Used in the production of acetylene gas, polyvinyl chloride, lime nitrogen, dicyandiamide, iron and steel desulfurizer, etc., used in electronics industry, teaching reagents. Calcium carbide is used for chemical production accounts for about 60%, and the remaining 40% is used for metal welding and cutting. Using calcium carbide as raw material can produce a series of chemical products, such as PVC resin, polyvinyl alcohol, vinyl acetate, neoprene rubber, butanol, octanol, tricyanoethylene, tetracyanoethylene, acetaldehyde, acetylene carbon black, lime nitrogen, etc.
