800 mesh weight calcium carbonate Industrial use of light calcium carbonate in Yizhong, Hebei
800 mesh heavy calcium carbonate
It is commonly used powder inorganic filler It has the advantages of high chemical purity, great inertia, difficult chemical reaction, good thermal stability, low oil absorption rate, low refractive index, soft, dry, free of crystal water, harmless, tasteless, odorless, good dispersion, etc.
Heavy calcium carbonate: it is mainly used in papermaking, rubber and plastic industries with large filling volume, mainly as bulk filler, to reduce the manufacturing cost of applied products;
Yizhong Light Calcium Carbonate: It is relatively widely used in plastic, rubber coating , adhesives, cigarette paper, ink, etc., mainly volume filling.

Industrial use of calcium carbonate: 1. Application in plastic production
Calcium carbonate is widely used in filling polychloride ethylene （ PVC ）, polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene copolymer (ABS) and other resins. Adding 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. It can also play the following roles:
(1) Improve the dimensional stability of plastic products;
(2) Improve the hardness and rigidity of plastic products;
(3) Improve the processing properties of plastics;
(4) Improve the heat resistance of plastic products;
(5) Improving the astigmatism of plastics;
(6) It can make products have some special properties;
(7) Reduce the cost of plastic products.
2. Application in food industry
It can be used as an additive in the food industry. For example, it can be used as a variety of 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 39%, second only to calcium citrate, soluble in stomach acid, and has become a calcium supplement with more dosage forms and applications.
3. Application in the construction industry
It can be used as raw material for plastic factory, rubber factory, paint factory, waterproof material factory and internal and external wall painting. It has the characteristics of high purity, high whiteness, harmless, odorless, low quality of fine oil and low hardness. Marble is also an important building material that can be used for building.
4. Application in chemical manufacturing industry
350 mesh to 400 mesh can be used for manufacturing gusset plate, downpipe and chemical industry. 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, cable, pvc, with whiteness above 94 degrees.
