China Calcium Carbonate Heavy Calcium Carbonate Light Calcium Carbonate

Heavy calcium is widely used in daily chemical industry as fillings in artificial bricks, rubber, plastic, papermaking, coating, paint, printing ink, electric cable, food, medicine, spinning and weaving ,fodder and tooth paste, etc. lt can help to increase the volume of the products and reduce the costs.

In rubber , it can reduce the amount of expensive natural rubber, increase its volume , reduce costs, After adding calcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate

In chemical manufacturing materials, it is heat-proof, chemical corrosion-proof, cold-proof, noise, shockproof and easy to process. Therefore it can be used to make doors, dry motor ,ceilings, wallboard,Plumbing irrigation,handrail of stairs, floor board and electric wire, etc.

In painting, coating ,it is as the filling and as the framework, Latex paint more than 30% amount are used in thick paint ,26%-60% amount are usedPlastic Machinery in water-based pain , It is not easy to make the coating deposition, easily dispersed ,good gloss

In plastic, it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products. It can also improve the processing properties and heat resistance and astigmatism.

As paper pulp material, it can fully make use of its high whiteness, affinity to water and shock intensity. and it is low cost widely using .

Using in coal-fired power plant desulfurization

Limestone flue gas desulfurization is calcium carbonate and sulfur dioxide synthesis of calcium sulfite during Coal-fired process and then Combined with oxygen air oxidation gypsum (calcium sulfide),Which can be reduced 90%

Sulfur dioxide produced by coal-fired plants, Produce gypsum for cement and Gypsum plant

In Feed, pharmaceutical industry, making calcium additives, replace the original shell powder to reduce costs.

Often used in the construction and paper industries.Less than 200 mesh: can be used for various feed additives, calcium content of more than 55.6, no harmful ingredients.
250 to 300 mesh: used as plastic plant, rubber plant, coating plant, waterproof material and interior and exterior wall painting. Whiteness above 85 degrees.
350 mesh to 400 mesh: used for making buckle plate, falling pipe, chemical industry. Whiteness above 93 degrees.
400 mesh to 600 mesh: can be used toothpaste, paste, soap. Whiteness above 94 degrees
800 mesh: for rubber, plastic, cable, PVC, whiteness above 94 degrees
1250 items: PVC, PE, paint, coating grade products, paper base coating, paper surface coating, white degree above 95 degrees. With high purity, high whiteness, non-toxic, odorless, fine, low oil, low hardness.
Calcium carbonate can be used as calcium supplement: the absorption rate can reach 39%, only next to calcium citrate, soluble iCar Electronics n gastric acid. It has become the most abundant dosage form and the most widely used calcium supplement.
