gas welding carbide stone welding calcium carbide rate per kg
Calcium carbide. It is prepared by mixing quicklime with coke and calcination. It reacts with water to produce acetylene gas, which can be used for lighting, welding and metal cutting.
Product name: Calcium carbide
Other name: calcium acetylide, acetylene calcium carbide, GA
Shape: white crystal, industrial products for black lumps, purple or grey section
Partical size avaliable: 1-4mm, 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.
Application: Mainly used to produce acetylene gas. It is also used for organic synthesis, oxyacetylene welding etc...Acetylene produced by the reaction of calcium carbide with water can be used to synthesize many organic compounds, such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc...Heating the powdered calcium carbide and nitrogen, the reaction of calcium cyanamide, namely lime nitrogen, cyanide salt and lime nitrogen heating melt reaction for mining gold and nonferrous metal industry. Calcium carbide itself can be used in the iron and steel industry desulfurizer. Production of polyvinyl choride(PVC).
Packing: Packed in 50kg iron drums or 100kg iron drums,22.5MT per 20’fcl.
