Карбида кальция (50-80 мм Размер)

Calcium carbide(Size 50-80mm) Molecular formula: CaC2 Molecular weight: 64.10 ( according to 2001 international relative atomic mass) Gas Yield: 290L/kg, 295L/kg or as customer requirements Package: New iron drum with 50kg/drum, 100kg/drum Size: 7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-120mm, 120-200mm or as customer requirements Properties: This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when met fire. The acetylene gas mix with air will form explosive gas( explosive range of acetylene gas in the air is 2.3%-81%. ) Quality Standard: Product quality should be in accordance with national standard GB10665-2004. Melting point: 1980 C(content 52.5% of CaC2), Specific gravity: 2.32(content 80% of CaC2) PH3 (V/V): 0.08% max H2S (V/V): 0.10 % max Application: Mainly used as materials to produce Acetylene Gas, Chloroprene Rubber, Calcium Cyanamide, Acetate Acid, Trichloroethylene and be as remover of Sulfur in steell industry and metal bonding and cutting, etc. Use: Used as materials of organic synthesis, widely used in metal bonding and cutting Storage and transportation: Calcium carbide pail should be sealed. Stored in dry, cool and draughty place. Should separate from other combustible and explosive material. We can provide Calcium carbide at very competitive price and excellent quality. If you are not satisfied with above specification we can produce according to your requirements.
