Usage:   Calcium carbonate is an inorganic compound with the formula CaCO₃, which is the main component of limestone, marble, etc. Calcium carbonate is usually white crystal, odorless, basically insoluble in water, and easy to react with acid to release carbon dioxide. It is one of the common substances on the earth, present in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

Industrial use

Calcium carbonate is a valuable resource for a wide range of uses limestone as a mineral raw material trade name. Limestone has been widely used in the history of human civilization because of its wide distribution and easy access in nature. As an important building material has a long history of mining, in modern industry, limestone is the main raw material for the manufacture of cement, lime, calcium carbide, is an indispensable flux limestone in the metallurgical industry, high-quality limestone after ultrafine grinding, is widely used in paper, rubber, paint, coatings, medicine, cosmetics, feed, sealing, bonding, polishing and other products manufacturing. According to incomplete statistics, the total ratio of limestone and building stone consumed in cement production, lime production, metallurgical flux, and ultra-fine calcium carbonate consumed limestone is 1∶3. Limestone is a non-renewable resource, with the continuous progress of science and technology and the development of nanotechnology, the application of limestone will be further expanded.

For plastic production

Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene copolymer (ABS) and other resins. The addition of calcium carbonate has a certain effect on improving some properties of plastic products to expand its application range. In plastic processing, they can reduce the shrinkage rate of resin, improve the flow transformation and control the viscosity.

Used in food industry

It can be used as an additive in the food industry. For example, can be used in a variety of feed additives, calcium content of more than 55.6%, no harmful ingredients. Can be used as a calcium supplement, the absorption rate can reach 39%, second only to calcium fruit acid, soluble in stomach acid, has become the most dosage form, the most used calcium supplement.

Used in the construction industry

It can be used as raw materials for plastic factory, rubber factory, coating factory, waterproof material factory and interior and exterior wall painting. It has the characteristics of high purity, high whiteness, non-toxic, odorless, low fine oil and low hardness. Marble is also an important building material that can be used in the construction of houses.
