1.Calcium Carbonate Description:

Calcium carbonate is an inorganic compound, commonly known as limestone, Greystone, stone powder, marble, calcite, alkaline, soluble in acid, Basically insoluble in water.

Heavy calcium carbonate, simply called heavy calcium, is a white powder made of fine calcite.lts chief composition is CaCO3. It displays such properties as whiteness, purity, soft colour and stability in chemical composition. Therefore it is a very good filling widely used in industry.

3.Calcium Carbonate Main Use:

In rubber , 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,waterpipe,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 used 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 .

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