What are the industrial applications of calcium carbonate? A calcium carbonate manufacturer is here to introduce them to you!
Release time:
2023-05-13
Calcium carbonate is a valuable resource with a wide range of applications, and limestone is the commercial name for this mineral raw material. Due to its widespread occurrence in nature and ease of extraction, limestone has been extensively utilized throughout the history of human civilization; as an important construction material, it boasts a long mining history. In modern industry, limestone serves as the primary raw material for the production of cement, lime, and calcium carbide, and acts as an indispensable flux in the metallurgical sector. High-quality limestone, after ultrafine grinding, is widely employed in the manufacture of paper, rubber, paints, coatings, pharmaceuticals, cosmetics, animal feed, sealants, adhesives, and polishing agents. According to incomplete statistics, the ratio of limestone consumed in cement production to that used for architectural stone, lime production, metallurgical fluxes, and ultrafine calcium carbonate is 1:3. Limestone is a non-renewable resource. With continuous advances in science and technology and the development of nanotechnology, the application scope of limestone will continue to expand.

1. Applications in plastic production. According to calcium carbonate manufacturers, calcium carbonate is widely used as a filler in resins such as PVC, PE, PP, and ABS. The addition of calcium carbonate can enhance certain properties of plastic products and broaden their range of applications. During plastic processing, it helps reduce resin shrinkage, improve rheological behavior, and control viscosity. It also serves the following functions: (1) enhancing dimensional stability of plastic products; (2) increasing hardness and rigidity; (3) improving processability; (4) enhancing heat resistance; (5) improving light scattering; (6) imparting specific special properties to the product; and (7) reducing the cost of plastic products.
2. Applications in the food industry. It can be used as a food additive. For example, it is suitable for various feed additives, with a calcium content of 55.6% or higher and no harmful impurities, making it an effective calcium supplement with an absorption rate of 39%, second only to calcium citrate. Calcium citrate is soluble in gastric acid and has become the most widely used calcium supplement.
3. Applications in the construction industry. According to calcium carbonate manufacturers, it can be used as a raw material in plastic, rubber, paint, and waterproofing-material factories. It is suitable for both interior and exterior wall coatings and is characterized by high purity, high whiteness, odorlessness, fine particle size, and low hardness. Marble is also an important building material and can be used in construction.
4. Applications in the chemical manufacturing industry. According to calcium carbonate manufacturers, 30–400 mesh grades can be used to produce ceiling tiles, downspouts, and various chemical products, with a whiteness of 93 or higher; 400–600 mesh grades are suitable for toothpaste and soap, boasting a whiteness of 94 or higher. The 80-mesh grade is employed in rubber, cable, and PVC applications, with a whiteness of 94 or higher, and can also serve as a raw material for producing optical neodymium glass and other specialized materials.
5. Nutritional supplements. According to calcium carbonate manufacturers, most calcium tablets on the market have calcium carbonate as their main ingredient. Calcium carbonate should be taken with meals because, as a carbonate, it readily produces carbon dioxide in an acidic environment, making it unsuitable for individuals with insufficient gastric acid secretion or those currently taking proton pump inhibitors.
