The price of 400-mesh heavy calcium carbonate powder is also quite different according to the cost of materials in different regions and production costs, as well as the whiteness of heavy calcium carbonate powder. Heavy calcium carbonate powder 400 mesh is usually used as filler, and is also widely used in artificial floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other daily chemical industries , as a filler to increase the volume of the product and reduce production costs. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role, and adjust the hardness of rubber.
Application functions of heavy calcium carbonate powder 400 mesh in various industries:
1. Use in the coal-fired power plant industry
Limestone flue gas desulfurization is to synthesize calcium sulfite with calcium carbonate and sulfur dioxide produced in the process of coal combustion, and then contact with air to oxidize into gypsum (calcium sulfate), which can effectively reduce the emission of sulfur dioxide from coal-fired power plants by up to 90%. The desulfurized gypsum produced can be directly sold to cement factories or gypsum board factories. The amount of calcium carbonate desulfurization powder is related to the sulfur content in coal, usually 300,000 kilowatts of coal-fired power plants need 40,000 tons of desulfurization powder per year.
2. Use in putty coatings
Heavy calcium powder is mainly used in putty coatings to reduce cost and improve hardness. It is used as the main filler. Generally, heavy calcium powder is required to be about 400 to 325 mesh, and the whiteness is not less than 80%.
3. Use in feed industry
The heavy calcium powder used in the feed industry requires that the fineness of the heavy calcium powder be 325 mesh, the whiteness requirement: 95%, and the calcium carbonate content: 99%, pure and free of impurities. Calcium carbonate can increase the calcium content in the feed and improve the quality of the feed.
4. Use in the floor tile industry
Heavy calcium carbonate (heavy calcium powder) for floor tiles: 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, (pure and no impurities) calcium carbonate can be used in the floor tile industry to increase the whiteness of the product. degree and tensile force, improve the toughness of the product and reduce the production cost.
5. Use in the paper industry
Heavy calcium carbonate (heavy calcium powder) for papermaking requires that the fineness of heavy calcium powder is not less than 325 mesh, the whiteness requirement: 95%, and the content of calcium carbonate: 98%. Calcium carbonate plays an important role in the paper industry. It can ensure the strength and whiteness of the paper, and the cost is low.
6. Use in the paper industry
Heavy calcium carbonate (heavy calcium powder) for papermaking: 325 mesh, whiteness requirement: 95%. Calcium carbonate content: 98%. Calcium carbonate plays an important role in the paper industry, which can ensure the strength and whiteness of the paper, and the cost is low.
7. Use in the rubber industry
Heavy calcium carbonate powder for rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%, calcium carbonate is one of the most used fillers in the rubber industry. A large amount of calcium carbonate is filled in rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing costs. Calcium carbonate is filled into rubber to obtain higher tensile strength, tear strength and abrasion resistance than pure rubber vulcanizates.
8. Use in artificial marble industry
Heavy calcium carbonate (heavy calcium powder) for artificial marble: the fine base of heavy calcium powder is required to be 325 mesh to 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, (pure and no impurities) calcium carbonate has been widely used. Used in the production of artificial marble.
