Wholesale Heavy Calcium Carbonate Powder Cheap Price
1,Package
50kg/bag,1-1.2t/bag,PP Bag.
2,Property
High whiteness,purity,soft color,stability in chemical composition
3,Usage and Function
1)In rubber,reduce the amout of expensive natural rubber,increase it's 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 manufactuering materials,it is heat-proof,chemical corrosion-proof,cold-proof,noise,shock proof and easy to process,it can be used to make doors,dry motar,ceilings,wallboard,waterpipe,handrail of stairs,floor board and electric wire.
3)Painting,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.
4)Plastic,increase the volume of plastics,reduce the costs,improve the size ,stability,hardness and tencity of plastic products improve the processing properties and heat resistance and astigmatism
5)Paperpulp material it can fully make use of it's high whiteness,affinity to water and shock intensity,it is low cost widely using.
6)Using in coal-fired power plant desulfurization limestone flue gas desulfurization is calciume carbonate and sulfur dioxide synthesis of calcium sulfite during coal-fired process and then combined with oxygen air oxidation gypsum ,which can be reduced 90% sulful dioxide produced by coal-fired plants,produce gypsum for cement and gypsum plant
7)In feed,pharmaceutical industry,making calcium additives,replace the original shell powder to reduce costs.
