1. Chemical name: calcium carbonate
2. Molecular formula: CaCO3
3. Molecular weight: 100.09
4. CAS: 471-341-1
5. Properties: White solid, tasteless and odorless. Insoluble in water and alcohol. Reacts with dilute acid and releases carbon dioxide at the same time, showing an exothermic reaction. Also soluble in ammonium chloride solution. Almost insoluble in water. Decomposes at 825~896.6ºC. Melting point 1339ºC. It is stable in the air and has slight moisture absorption ability.
6. Usage: It can be used as filler in rubber, plastics, papermaking, paint and ink industries. It is widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a seeding agent for industrial wastewater, an antacid for gastric and duodenal ulcers, an antidote for acidosis, an SO2 eliminator in SO2-containing waste gas, a dairy feed additive, and an anti-sticking agent for linoleum felts. . It can also be used as raw material for tooth powder, toothpaste and other cosmetics.
7. Packaging: lined with polyethylene plastic bag, outer plastic woven bag, 25Kg per bag.
8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse, handled with care, to prevent moisture and heat. During transportation, it should be protected from rain and moisture, and should be isolated and stacked away from toxic substances.
