Function:
Rubber industry plastics industry paint industry
waterborne coatings industry
In addition, calcium carbonate plays an important role in
the paper industry to ensure the strength, whiteness and low cost
of paper.In the cable industry can play a certain role in
insulation.It can also be used as a friction agent for
toothpaste.
Advantages:
1)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
2)Chemical manufacturing materials: it is heat-proof, chemical corrosion-proof,cold-proof, anti-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)Plastic : it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products.
