The difference between the light calcium carbonate and calcium carbonate

                         The difference between the light calcium carbonate and calcium carbonate

A, referred to as "coarse whiting, heavy calcium carbonate is made of high quality calcite as raw material processed white powder, it is the main component of CaCO3, insoluble in water and ethanol, with high whiteness, purity, hue and soft and stable chemical composition, etc, is the industry most inorganic fillers.

Coarse whiting is usually used as a filler, but also widely used in artificial floor tile, rubber, plastic, papermaking, coating, paint, printing ink, cable, construction supplies, food, medicine, daily chemical industry such as textile, feed, toothpaste, as a filling agent rise to increase the volume of products, reduce the production cost.

Used in rubber, can increase the volume of the rubber, to improve the rubber processability, half reinforcing or reinforcing effect, and can adjust the hardness of rubber. Used in chemical building materials with heat resistance, chemical corrosion resistant, cold resistant, sound insulation, shockproof and easy processing features, can do door, ceiling, wall panel, fluctuation, stair handrail, floor and wires, etc., in oil paint, coarse whiting as filler, can play a role skeleton.

In the plastic, can increase the volume of plastic, reduce product cost, improve the dimension stability of plastic and plastic hardness and rigidity, and improve the processing properties of plastics, improve the heat resistance of plastics, improve plastic astigmatism. Do the pulp material, make full use of coarse whiting high whiteness and good hydrophilicity, high impact strength, etc.

Heavy calcium carbonate can be heat resistance, resistance to chemical corrosion, hardy, sound insulation, shockproof and easy processing features, such as used in the chemical building materials, building ceramics and floor tile, doors, ceilings, walls and fluctuation water irrigation, stair handrail, floor and wires, etc. Can also be used in papermaking, coating, paint, PVC, artificial leather, PVC gusset plate, medicine, food, cosmetics, printing ink, etc.

2, light calcium carbonate in limestone as raw materials, mainly used in rubber, plastics, paper and coating, ink and other industries as a filling agent, and can be used for tooth powder, toothpaste, cosmetics and other daily chemical products, can also be used for organic synthesis, metallurgy, glass, and in the production of asbestos.

Coarse whiting in natural mineral water, grinding to paint with white and fine degrees.

After light calcium is a caco3 calcine, soluble in water, post-processing, caco3.

Third, on the coating application

1, coarse whiting relatively safe, dry covering power is not high. Is not as good as light calcium whiteness, but the price is cheap.

2, light calcium if careless use, when using very easy cause serious thickening, after coating is the most serious agglomeration. Oil absorption proportion of calcium big many, has a high alkaline.
