Calcium carbonate
Calcium carbonate always means Heavy Calcium Carbonate, simply called Heavy Calcium, is a white powder made of fine calcite.Its chief composition is CaCO3. It displays such properties as whiteness, purity, soft color and stability in chemical composition. Therefore it is a very good filling widely used in industry.

Application :
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 and 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
● 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 Feeding:
Used in pharmaceutical industry, making calcium additives, replace the original shell powder to reduce costs.
