Calcium Carbide packed in 50kg drums and 100kg drums or as customer's requirement.
And 22.5 tons per 1x20'fcl without pallet for Calcium carbide stone price for calcium carbide per ton in china
1).The main raw material for producing acetylene gas.
2).Cutting and welding for metal material.
3).To synthesize polyvinyl chloride(PVC).
4).Fruit catalyst.
5).The basic material for organic: verdana,geneva;
6). Reacting with nitrogen to product lime nitrogen.
7).The desulfurizer in steel industry.
The packing must be kept in good condition and the goods should be stored in a dry,cool and ventilated place.It should be separate from the cargo can burn and acid.It should avoid meeting water and moisture.It should give off the acetylene in iron drum before storing in warehouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
Q1:Are you a factory or trader?
A1:We are directly factory combined production and export and one of the biggest factory in China.
