Product name: Calcium carbide
CAS No.: 75-20-7
Molecular Weight: 64.10
Molecular Formula: CaC2
Gas yeild: 285-305l/kg
Appearance: Grey, black solid, purple when its purity is more than 90%.
Packing: 50 or 100kg/ iron drum diameter: 560*670
Pail pack colour: Black gray green
It is grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18°C), melting point is 2300°C, 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 releases heat.
Calcium carbide Production process:
The production methods of aerobic hot and heating method. General electric heating method is used more production calcium carbide, namely the quick lime and carbon materials (coke, anthracite or petroleum coke) in calcium carbide furnace, rely on the arc high temperature melting reaction and generate calcium carbide
Calcium carbide reaction with water generated acetylene can be synthesized many organic compounds, such as synthetic rubber, synthetic resin, acetone, ketene, such as carbon black, Meanwhile acetylene a widely used in metal oxygen flame welding and cutting.
The powdery calcium carbide heating with nitrogen, reaction products. It cyanogen ammoniation, namely lime nitrogen, calcium lime n and salt reaction heat generated cyanogen melt used for mining gold and non-ferrous metal industry.
Calcium carbide itself can be used in the steel industry desulfurizer.
produced gas encounters fire after burn, can lighting.
To synthesize polyvinyl chloride(PVC).
TIANJINSHI JINHONGWEIBANG CHEMICAL Co., Ltd is located near Tianjin New Port.
It covers an area of 15000 square kilometers. My company has my own factory, which has taken up chemical business for 15 years. So we have many customers in domestic markets and international markets. Our main customers spread in west-Africa, MID- East, south America, south-east Asia etc. And my factory won good reputation. Our principle is: Quality first, Prestige first. My trade marks: JINHONG.
Besides, we have independent import& exp rights. And we can transact a series of process of export including danger packaging, Dangerous careful card, Performance certificate, CO ( certificate of origin ) etc
1 we are direct manufacturer, not trader, so the price is much competitive and delivery time is assured.
2 we are near to Tianjin port and have own transportation, which decrease cost, it make us be superior to other supplier.
3 we have crush machine which is used to crush big size into small size as customer required, so the size is assured.
4 packing: Calcium carbide packed with thick PVC bag, then packed into new steel drum, the drum is sealed well to protect calcium carbide.
5 We have good sales of calcium carbide for a long time, the customer from Ukrain, Pakistan, Malaysia, Nigeria, Lebanon, India, Venezuela, Ecuador, Ivory Coast, Sri Lanka and so on, all of them order second time again.
