Hefty (Ground) Calcium Carbonate is extensively used as filler and improver.
Purity: 98%min.
Appearance: white powder.
Large calcium carbonate, also called ground calcium carbonate, is produced by normal exceptional calcite, which has higher purity and whiteness. The measurement ranges from unEPT400 mesh which is known as major merchandise, to 2000 mesh or above, dependent on your need.
Weighty (Floor) Calcium Carbonate is extensively utilised as filler and improver in plastic, paint, paper-producing, rubber, pharmacy, feed, day-to-day chemical, ceramics, adhesives and ink market.

Calcium carbonate Software:
one)Rubber:
it can reduce the volume of expensive organic rubber,improve its quantity ,decrease charges, Right after incorporating calcium carbonate then can be acquire larger energy tensile ,tear power and abrasion resistance than the pure Rubber vulcanizate
2)Chemical producing components
it is heat-evidence, chemical corrosion-proof,cold-proof, anti-noise, shockproof and simple to process. Therefore it can be employed to make doors, dry motar ,ceilings, wallboard,waterpipe,handrail of stairs,ground board and electric powered wire,and so forth.
three)Portray amp coating:
it is as the filling and as the framework, LaEPT paint much more than thirty% sum are utilized in thick paint ,26%-60% amount are employed in drinking water-primarily based ache
four)Plastic:
it can enhance the quantity of plastics, minimize the charges, increase the size, stability, hardness and tenacity of plastic merchandise.
five)Paperpulp material:
it can completely make use of its large whiteness, affinity to h2o and shock intensity, minimal price widely employing .
6) Coal-fired EPT and EPTed sulfurization
seven)Feed,pharmaceutical sector
making calcium additives, change the authentic shell powEPTto decrease charges.
