Heavy calcium carbonate powder 400 mesh is usually used as a filler, and is also widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. , 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 function of heavy calcium carbonate powder 400 mesh in various industries:
1. Application in coal-fired power plant industry
Limestone flue gas desulfurization is to synthesize calcium sulfite from calcium carbonate and sulfur dioxide produced in the process of coal combustion, and then oxidize it into gypsum (calcium sulfate) in contact with air, which can effectively reduce the emission of sulfur dioxide produced by coal-fired power plants by up to 90%. The desulfurized gypsum produced can be sold directly to cement plants or gypsum board plants as products. The amount of calcium carbonate desulfurization powder is related to the sulfur content in coal, usually 40,000 tons/year of desulfurization powder is required for a 300,000-kilowatt coal-fired power plant.
2. Application in putty coating
The use of heavy calcium powder in putty coatings is mainly to reduce costs, increase hardness, and be 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. Application in feed industry
The heavy calcium powder used in the feed industry requires the fineness of the heavy calcium powder to be 325 mesh, the whiteness requirement: 95%, 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. Application in floor tile industry
Ground calcium carbonate (heavy calcium powder) for floor tiles: 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, (pure and free of impurities) calcium carbonate can be used in the floor tile industry to increase the whiteness of the product Degree and tension, improve the toughness of the product, reduce production costs.
5. Coatings used in the paper industry
Heavy calcium carbonate (heavy calcium powder) for papermaking requires that the fineness of the heavy calcium powder is not less than 325 mesh, the whiteness requirement: 95%, and the calcium carbonate content: 98%. Calcium carbonate plays an important role in the paper industry. It can guarantee the strength and whiteness of the paper, and the cost is low.
6. Uses 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 paper, and the cost is low.
7. Application in rubber industry
Ground calcium carbonate powder for rubber: 400 meshes, 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 the rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing the cost. Calcium carbonate is filled into rubber, which can obtain higher tensile strength, tear strength and abrasion resistance than pure rubber vulcanizate.
8. Application in artificial marble industry
Heavy calcium carbonate (heavy calcium powder) for artificial marble: the fine bottom of heavy calcium powder is required to be 325 mesh to 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, (pure and impurity-free) calcium carbonate has been widely used Used in the production of artificial marble.
