1) We supply the calcium carbide (cac2) with the following specifications:
Calcium carbide Gas Yield: 285L/kg, 295L/kg, 305L/kg.
2) Calcium carbide Package: New iron drum with 50kg/drum, 100kg/drum, 200kg/drum.
3) Calcium carbide Size: 0-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-120mm, 120-200mm
4) Grey or black solid with a garlic-like odour, the higher purity will be purple
Melting point: 447centigrade
Boiling point: 2300centigrade
The product can absorb water in the air and conduct electricity. They higher its purity is, the easier it conducts, it dissolves in water, turns into acetylene and calcium hydroxide and release heat.
5) Trade conditions:
Payment: 30% T/T as deposit, 70% balance against the B/L COPY
Delivery Time: 15days.
Trade Term: FOB Qingdao or CIF.
Production Capacity: 20, 000T/year.
|Gas yield||≥ 295 L/KG||300|
|Lump size||50-80mm|| 50-80|
|H2S||≤ 0.10 (V/V)||0.05|Usage
Calcium carbide is one of the basic raw material of organic synthesis industry. It is also an importat raw material of acetylene industry.
(1) The reaction of calcium carbide with water, producing acetylene and calcium hydroxide.[CaC2 + 2 H2O → C2H2 + Ca(OH)2].
This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide. eg.synthetize rubber,synthetic resin,acetone,ketene and carbon blace. Meanwhile oxygen-acetylene flame is widely used in metal welding and cutting.
(2) Heating powdered calcium carbide and nitrogen to producing calcium cyanamide,which can react with sodium chloride producing black cyanide. Black cyanide is used in gold mining and non-ferrous metal industry.
(3) Steelmaking: as a powerful deoxidizer at ladle treatment facilities.
(4) Calcium carbide is used in carbide lamps, in which water drips on the carbide and the acetylene formed is ignited.
(5) In the ripening of fruit, calcium carbide is sometimes used as source of acetylene gas, which is a ripening agent similar to ethylene.pictures of products:
