Calcium Carbonate

1. Product description:

Calcium carbonate, also known as limestone and stone powder, is a common chemical substance on the earth. It is an inorganic salt mineral. It is alkaline, hardly soluble in water, and easily soluble in acid. It naturally exists in aragonite, calcite, chalk, limestone, and large Chemicalbook. In rocks such as marble and limestone, the insoluble calcium carbonate in the limestone layer and the water with dissolved carbon dioxide can be converted into calcium bicarbonate, and the water with the dissolved calcium bicarbonate can also precipitate calcium carbonate, 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 membranes and capillary permeability. The main component of animal bones or shells is calcium carbonate. Calcium carbonate used in medicinal and edible additives is made of calcite. Because of its calcium supplementation after purification, sterilization, filtration, and refining, it needs to be used in large quantities 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 beverages such as Wahaha, Juneng Calcium, and Jelly Kizhilang as a fortifier to meet the body's calcium demand. According to 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 (abbreviated as light calcium) is to calcinate raw materials such as limestone to produce lime (the main component is calcium oxide) and carbon dioxide, then add water to digest the lime to produce milk of lime (the main component is calcium hydroxide), and then pass it in Carbon dioxide carbonizes the milk of lime to form calcium carbonate precipitation, which is finally obtained by dehydration, drying and pulverization. Or first use sodium carbonate and calcium chloride for metathesis reaction to generate calcium carbonate precipitation, Chemicalbook is then prepared by dehydration, drying and crushing. It is mainly used as a filler in rubber, plastics, papermaking, coatings, inks and other industries, and can be used It can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production. The preparation method of heavy calcium carbonate (heavy calcium for short) is prepared by mechanically directly crushing natural calcite, limestone, chalk, shells, etc., it is an excellent filler and performance modifier, widely used in plastics, rubber, Papermaking, coatings, feed, medicine, daily chemicals, glass, ceramics and other fields. Active calcium carbonate (abbreviated as active calcium) is prepared by surface modification of light calcium or heavy calcium with a surface modifier. The modified calcium carbonate powder forms a special coating on the surface The structure can significantly improve the dispersibility and affinity in the polymer matrix such as polyolefin, and it can produce an interface effect with the polymer matrix, thereby improving the impact strength of the product. It is an incremental type with excellent performance. Filling aids. It reacts with acid to produce gaseous carbon dioxide that makes lime water turbid. This is the easiest way to identify carbonate ions.
