Physical Properties of Heavy Calcium Carbonate
( Standards HG/T3249-2001):
Composition | CaCO3 | Density(g/cm3) | Hardness | Whiteness | PH | Moisture content |
Content% | 70-98 | 2.7-4.5 | 2.5-3.5 | 84-97 | 8-9 | < 0.5 |
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, 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
In plastic, it can increase the volume of plastics, reduce the costs, improve the size, stability, hardness and tenacity of plastic products. It can also improve the processing properties and heat resistance and astigmatism.
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 .
Using in coal-fired power plant desulfurization
Limestone flue gas desulfurization is calcium carbonate and sulfur dioxide synthesis of calcium sulfite during Coal-fired process and then Combined with oxygen air oxidation gypsum (calcium sulfide),Which can be reduced 90%
Sulfur dioxide produced by coal-fired plants, Produce gypsum for cement and Gypsum plant
In Feed, pharmaceutical industry, making calcium additives, replace the original shell powder to reduce costs.
In 25kg or 50kg bags.
