Coated & un coated calcium carbonate:1.purity :98%.
2.Whiteness:98.
3.have self export authority
?
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.

? 1)In rubber , it can reduce the amount of expensive natural rubber, increase its volume , reduce costs, After addingcalcium carbonate then can be obtain higher strength tensile ,tear strength and abrasion resistance than the pure Rubber vulcanizate
?
2) 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 motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electric wire,etc.
3)In painting, coating ,it is as the filling and as the framework,Latexpaintmore 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
4)In plastic, it can increase the volume of plastics,reduce the costs,improve the size, stability, hardness and tencity of plastic products.It can also improve the processing properties and heat resistance and astigmatism.
5).As paperpulp material,it can fully make use of its high whiteness, affinity to water and shock intensity.and it is low cost widely using .
