Product Description:
Calcium carbonate is also known as limestone, stone powder, is a common chemical substance on the earth, belongs to inorganic salt minerals, is alkaline, insoluble in water, easy to dissolve in acid, naturally exists in aragonite, calcite, chalk, limestone, marble, limestone and other rocks, limestone rock insoluble calcium carbonate and dissolved carbon dioxide water can be converted into calcium bicarbonate. Calcium carbonate can also be precipitated from water dissolved with calcium bicarbonate, which is the reason for the formation of karst caves.

Calcium is necessary to maintain the normal function of human nerves, muscles, skeletal system, cell membrane and capillary permeability, and the main component of animal bones or shells is calcium carbonate. Calcium carbonate used in medicinal and edible additives is made from calcite. Due to its calcium supplement effect after purification, sterilization, filtration and refining, it needs to be used in the process of preparing penicillin, streptomycin and oxytetracycline. It is used as an additive in food to ensure the calcium intake necessary for the human body, such as chewing gum, chocolate and wahaha, giant calcium, jelly and other drinks as a fortifying agent to meet the needs of the human body for calcium.
According to the different production methods, calcium carbonate can be divided into light calcium carbonate, heavy calcium carbonate and active calcium carbonate.
The preparation method of light calcium carbonate (referred to as light calcium) is to calcination of limestone and other raw materials to produce lime (mainly calcium oxide) and carbon dioxide, and then add water to digest lime to produce lime milk (mainly calcium hydroxide), and then pass carbon dioxide carbonized lime milk to produce calcium carbonate precipitation, and finally by dehydration, drying and crushing. Or first with sodium carbonate and calcium chloride for double decomposition reaction to produce calcium carbonate precipitation, and then by dehydration, drying and grinding to produce, mainly used in rubber, plastics, paper and paint, ink and other industries as fillers, and can be used in tooth powder, toothpaste, cosmetics and other daily chemical products, can also be used in organic synthesis, metallurgy, glass and asbestos production.

The preparation method of heavy calcium carbonate (referred to as heavy calcium) is to directly crush natural calcite, limestone, chalk, shell, etc. It is an excellent filler and performance modifier, widely used in plastics, rubber, paper making, coatings, feed, medicine, daily chemical industry, glass, ceramics and other fields.
The preparation method of active calcium carbonate (referred to as live calcium) is to make light or heavy calcium by surface modification agent. The modified calcium carbonate powder forms a special coating structure on the surface, which can significantly improve the dispersibility and affinity in polyolefin and other polymer substrates, and can produce interface interaction with the polymer substrate. Thus improve the impact strength of the product, is a good performance of incremental filling additives.

Application: 

Calcium carbonate has a variety of applications. In the construction industry, it's used as a building material, adding strength to concrete and mortar. In the paper industry, it serves as a filler, improving paper brightness and opacity. In the food and supplement sector, it's a common calcium source, enhancing nutrition. In plastics and rubber manufacturing, it helps adjust hardness and durability. It's also used in toothpaste to aid in abrasion and cleaning.
