What is the industrial use of calcium carbonate? Calcium carbonate manufacturers for you!
Release time:
2023-05-13
Calcium carbonate is a valuable resource with a wide range of uses, and limestone is the trade name of mineral raw materials. Limestone has been widely used in the history of human civilization because of its wide distribution in nature and easy access. As an important building material, limestone has a long history of mining. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide, and is an indispensable flux limestone in the metallurgical industry. After superfine grinding, high-quality limestone is widely used in the manufacture of paper, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products. According to incomplete statistics, the ratio of limestone consumed in cement production to limestone consumed in building stone, lime production, metallurgical flux and ultrafine calcium carbonate is 1:3, and limestone is a non-renewable resource. With the continuous progress of science and technology and the development of nanotechnology, the application field of limestone will be further expanded.

1. Application in the production of plastics. Calcium carbonate manufacturers, calcium carbonate is widely used to fill PVC, PE, PP, ABS and other resins. The addition of calcium carbonate can improve some properties of plastic products and expand its application range. In plastics processing, they can reduce resin shrinkage, improve rheological properties and control viscosity. It can also play the following roles:(1) improve the dimensional stability of plastic products;(2) improve the hardness and rigidity of plastic products;(3) improve the processing performance of plastic;(4) improve the heat resistance of plastic products;(5) improve the astigmatism of plastic;(6) make the product have some special properties;(7) reduce the cost of plastic products.
2. Application in the food industry. It can be used as an additive in the food industry. Such as can be used for a variety of feed additives, calcium content of more than 55.6%, no harmful ingredients, can be used as a calcium supplement, absorption rate of 39%, second only to calcium citrate, calcium citrate soluble in gastric acid, has become the most widely used calcium supplement.
3. Application in the construction industry. Calcium carbonate manufacturers, can be used as a plastic factory, rubber factory, paint factory, waterproof material factory raw materials, can be used to paint the interior and exterior walls, with high purity, high whiteness, tasteless, fineness and low hardness characteristics, marble is also an important building material, can be used for construction.
4. Application in chemical manufacturing. According to calcium carbonate manufacturers, 30-400 mesh can be used to make gussets, downpipes and chemicals, with whiteness above 93 degrees, and 400 mesh to 600 mesh can be used for toothpaste and soap. Whiteness above 94 degrees. 80 mesh can be used for rubber, cable, pvc, whiteness above 94 degrees, and can also be used as raw materials for manufacturing optical neodymium glass.
5. Nutritional supplements. According to the manufacturer of calcium carbonate, the main component of most calcium tablets on the market is calcium carbonate. Calcium carbonate needs to be taken with meals. Because calcium carbonate contains carbonic acid, it is easy to produce carbon dioxide in an acidic environment. It is not suitable for people who have poor gastric acid secretion or are using gastric acid inhibitors.
