A minute to understand the types and applications of calcium carbonate
Calcium carbonate (CaCO3) is a white inorganic compound found in rocks such as calcite, marble, chalk, aragonite, limestone, etc., as well as a major component of animal bones and shells. Calcium carbonate is an important building material and has a wide range of industrial uses, including paper, rubber, plastics, glass, pharmaceuticals, pigments, alkali and other industries.
1.Heavy Calcium Carbonate
Heavy calcium carbonate is produced from natural calcite or marble by mechanical crushing and grinding.
1.1 Ordinary calcium carbonate
Ordinary calcium carbonate is produced by marble after cleaning, drying, crushing, grinding and other processes, cost-effective, usually used as filler, widely used in artificial floor tiles, rubber, plastic, paper, paint, paint, pigment, cable, building supplies, feed and other industries, as a filler to increase the volume of the product to reduce the role of the production cost.
1.2 Porcelain white calcium carbonate
Porcelain white calcium carbonate is produced by selecting natural calcite, after washing, drying, crushing, grinding and other processes, with high purity, high whiteness, easy to disperse, light transmission, temperature resistance, tear resistance, etc., used in modified plastics, high-transparent shoes, films, light diffusion panels, lampshades, corrugated pipes, MPP tubes, high-white PP household appliances, pigments, food, medicine and other industries.
2.Light Calcium Carbonate
Light calcium carbonate, also known as precipitated calcium carbonate, is produced by chemical processing. Light calcium is mainly used in rubber, plastics, paints, water-based coatings and other industries, filled into the rubber can be obtained than pure rubber vulcanizate higher tensile strength abrasion resistance, tear strength, and in the natural rubber and synthetic rubber has a significant reinforcing effect, and at the same time can be adjusted to the consistency; in plastics, coatings play a role in supporting the backbone, easy to dispersion, good gloss.
3.Ultrafine Functional Calcium Carbonate
NC-40A/60A/90A series products researched and developed by our company have the functions of high impact resistance and high fluidity, which are widely used in modified home appliance materials and automobile materials. Compared with ordinary calcium carbonate, ultrafine functional calcium carbonate has an increase of up to 94.4% in impact resistance, and an increase of more than 22.5% in fluidity performance.
