1. Product introduction
Chemical name is called calcium carbide, formula for CaC2, is the basic raw materials, organic synthetic chemistry by using calcium carbide as raw materials can be combined into a series of organic compound,
for industry,agriculture,medicine for raw material.Industrial calcium carbide is the main ingredient calcium carbide,and the rest are free calcium oxide,carbon and silicon,magnesium,iron,aluminum compounds and a small amount of phosphide and sulfide.Industrial calcium carbide is about 70% - 70% purity, impurity CaO accounted for about 24%,carbon,silicon,iron,calcium phosphate and calcium sulfide accounts for about 6%.
The new section of luster, appearance with different content of calcium carbide gray, brown, purple or black solids.With high calcium carbide is purple.Industrial density of 2.22 g/cm3 (18 ºC), melting point 2300 ºC, can conduct electricity, the higher the purity, conducting more easily.

3. Application
(1) the calcium carbide to generate acetylene after reaction with water can synthesis of many organic compounds,such as:synthetic rubber,synthetic resin,acetone,ketene,charcoal BlackAt the same time a oxygen acetylene flame is widely used for metal welding and cutting.
(2) heating powdered calcium carbide with nitrogen gas,reaction calcium cyanamide, namely lime nitrogen, heating lime nitrogen and salt of cyanide is used to melt Mining gold and nonferrous metal industry. 
(3) the desulfurizer calcium carbide itself can be used in the iron and steel industry.

4. storage and transport
(1) calcium carbide,crushing,the electric Chambers (library) and slag pit, should according to the provisions of the TJ31.
(2) calcium carbide should be stored in the ground in dry indoor, the air circulation, do not leak rain, the ground should be higher than that of the road, in order to avoid the water.
(3) the ban on using rolling slip loading and unloading, handling, calcium carbide bucket to avoid calcium carbide and bucket wall collision sparks.
(4) every time after taking calcium carbide, should cover the lid.
(5) ban on calcium carbide acetylene generator room, electric Chambers with the hammer.
(6) powder, particle size too small, calcium carbide slag shall have the specialist is responsible for the batch input pit water thoroughly decomposed to properly handle.
(7) of carbide slag pit should be open, top of the slag pits of mortar and grey water shall not be discharged into sewer.Should be to prevent slag iron tools, impact device
And local spark generation.
(8) calcium carbide and acetylene gas mixture on fire should be adopted when the dry sand, co2 or dry powder fire extinguisher to put out, it is prohibited to use water or foam fire extinguisher and
Carbon tetrachloride fire extinguisher extinguishing.
(9) calcium carbide in ladle can inject a certain amount of nitrogen, so reduce the oxygen content.

5. Process
The production methods of aerobic hot and heating method.General electric heating method is used moreproduction calcium carbide,namely the quick lime and carbon materials (coke,anthracite,petroleum coke) in
calcium carbide furnace,ely on the arc high temperature melting reaction and generate calcium carbide.
