PRODUCT DESCRIPTION

About Calcium carbonate: Calcium carbonate is a white fine crystalline powder, tasteless and odorless. There are two forms, amorphous and crystalline. Crystal type can be divided into rhombic and hexagonal crystal system (anhydrous calcium carbonate is colorless rhombic crystal, hexahydrous calcium carbonate is colorless monoclinic crystal), is columnar or rhomboid, density of 2.93g/cm3. The melting point is 1339℃ (decomposed at 825-896.6℃), and 1289℃ at 10.7MPa. Insoluble in alcohol, soluble in ammonium chloride solution, almost insoluble in water.

Calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystal calcium carbonate according to different production methods. According to the average particle size of calcium carbonate powder, calcium carbonate can be divided into particulate calcium carbonate, micro powder calcium carbonate and superfine calcium carbonate. Calcium carbonate can be divided into crystalline calcium carbonate and amorphous calcium carbonate according to the regular arrangement of atoms and ions that make up calcium carbonate. In addition, there are nano calcium carbonate and so on.

Calcium carbonate Usage:

1. Application in 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 their application range. In plastic processing, they can reduce resin shrinkage, improve flow distortion and control viscosity.

2. Application in food industry: it can be used as additive in food industry. For example, can be used in a variety of feed additives, calcium content of 55.6% or more, no harmful ingredients. Can be used as calcium supplements, absorption rate up to 39%, second only to calcium fruit acid, soluble in gastric acid, has become the most dosage forms, the most used calcium supplements.

3. Application in the construction industry: can be used as raw materials of 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 quality and low hardness. Marble is also an important building material for houses.

4. Application in chemical manufacturing industry: 350 to 400 purposes can be used to manufacture gusset plate, drain pipe, chemical industry. The whiteness is above 93 degrees. 400 mesh to 600 mesh can be used for toothpaste paste, soap. The whiteness is above 94 degrees. 800 mesh can be used for rubber, cable, PVC, whiteness above 94 degrees.

5. It can also be used to manufacture optical neodymium glass materials.
