[Packing]:
It's packing with metal pail.Net weight per bucket is 100kg±1kg or 200kg±2kg
[Reserve and transportation]:
The Calcium carbide bucket should be airproofand reserve in the specail warehouse where is ventilative、dry、shady and cool. When transported with trains,trucks and ships, should have strictly waterproof measures ,and be insulated with other combustible or explosive goods.
[Safety items]:
When fire happened,be sure that using dry fire extinguisher but not water or bubble ones.
[pplication]:
It is a important elementary material of organic compound industry.With material of calcium carbide and acetylene, ethene、neoprene、acetic acid、aldehyde、acetic ethene、acetic cyanide、 C2H4N4 、acetone etc. can be manufactured. It is alse used for cut and jointing of metal. Recentlyin domestic PVC is the main consumption domain of calcium carbide.
