Heavy (Ground) Calcium Carbonate is widely utilised as filler and improver.
Purity: ninety eight%min.
Look: white powder.
Large calcium carbonate, also called floor calcium carbonate, is created by natural excellent calcite, which has high purity and whiteness. The measurement ranges from unEPT400 mesh which is called principal products, to 2000 mesh or above, relying on your prerequisite.
Hefty (Floor) Calcium Carbonate is commonly employed as filler and improver in plastic, paint, paper-producing, rubber, pharmacy, feed, everyday chemical, ceramics, adhesives and ink sector.

Calcium carbonate Application:
1)Rubber:
it can minimize the volume of pricey all-natural rubber,improve its quantity ,lessen fees, Following introducing calcium carbonate then can be obtain larger strength tensile ,tear power and abrasion resistance than the pure Rubber vulcanizate
2)Chemical manufacturing resources
it is heat-evidence, chemical corrosion-proof,chilly-proof, anti-noise, shockproof and simple to process. As a result it can be used to make doorways, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,floor board and electrical wire,and so on.
3)Painting amp coating:
it is as the filling and as the framework, LaEPT paint a lot more than 30% sum are used in thick paint ,26%-60% amount are used in drinking water-primarily based discomfort
4)Plastic:
it can improve the volume of plastics, lessen the charges, boost the size, stability, hardness and tenacity of plastic merchandise.
five)Paperpulp substance:
it can completely make use of its substantial whiteness, affinity to water and shock depth, low cost widely making use of .
six) Coal-fired EPT and EPTed sulfurization
7)Feed,pharmaceutical industry
making calcium additives, substitute the original shell powEPTto minimize charges.
