3.Application of calcium carbide manufacturer
Calcium carbide is one of the basic raw material of organic synthesis industry.It is also an important 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.

FAQ
Q: Where is your plant located? Could we visit your plant?
A: Our carbide process & crush plant is located in Inner Mongolia, which is near carbide raw material place. We welcome all the valuable & precious customers visit us from all over the world.
Q: How can you guarantee the quality?
A: 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.
Q: What is the gas yield?
A: Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm is 295L/KG.
