Application scenarios

Calcium carbonate is an inorganic compound with the chemical formula CaCO₃. It is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, basically insoluble in water, and easily reacts with acid to release carbon dioxide. It is one of the most common substances on earth, existing in rocks such as aragonite, calcite, chalk, limestone, marble, travertine, etc. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and has a wide range of industrial uses.

1. Used in plastic production
Calcium carbonate is widely used to fill polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. Adding calcium carbonate has a certain effect on improving certain properties of plastic products to expand their application range. In plastic processing, they can reduce resin shrinkage, improve rheology, and control viscosity.

2. Used in the food industry
It can be used as an additive in the food industry. For example, it can be used in various feed additives, with a calcium content of more than 55.6% and no harmful ingredients. It can be used as a calcium supplement, with an absorption rate of up to 39%, second only to calcium tartaric acid. It is soluble in gastric acid and has become the calcium supplement with the most dosage forms and the most applications.

3. Used in the construction industry
It can be used as raw material for plastic factories, rubber factories, paint factories, waterproof material factories and for interior and exterior wall painting. It has the characteristics of high purity, high whiteness, non-toxic, odorless, low fine oil quality and low hardness. Marble is also an important building material that can be used for house construction.

4. Used in chemical manufacturing industry
350 mesh to 400 mesh can be used to make gussets, downpipes, and chemicals. The whiteness is above 93 degrees. 400 mesh to 600 mesh can be used for toothpaste paste and soap. The whiteness is above 94 degrees. 800 mesh can be used for rubber, cables, PVC, and the whiteness is above 94 degrees.

5. Used in fine ceramic materials
Calcium carbonate can be used to prepare high-temperature stable, dielectric, low thermal conductivity, microporous and highly pure ceramic materials. For example, white conductors widely used in spark plug preparation, as well as important fine ceramic materials such as semiconductor materials, alumina and enamel pigments.

6. Use as mineral filler and abrasive
Industrial calcium carbonate can also be used as mineral filler and abrasive. In the production of chemical and building materials, calcium carbonate can replace some expensive materials such as cerussite, talc and talcum powder. In abrasives, the particle surface of calcium carbonate can interact with the abrasive matrix to enhance the wear resistance and grinding efficiency of the abrasive to improve the efficiency and durability of the abrasive.

Environmental hazards
Dispose in accordance with the requirements of relevant national and local laws and regulations. Or contact the manufacturer or manufacturer to determine the disposal method. This substance is basically harmless to the environment. Do not pour it into the water without government permission.
Health hazards
Workers engaged in mining and processing often suffer from upper respiratory tract inflammation and bronchitis, which may be accompanied by emphysema. Lymph node calcification and enhanced lung texture appear on the chest X-ray. Pneumoconiosis in workers is mainly related to the silica impurities contained in this product.
Operation, disposal and storage
Closed operation, pay attention to ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks and chemical safety protective glasses. Avoid dust. Avoid contact with acids. Storage precautions: It should be stored separately from acids.
