About Product - Calcium Carbonate Industry

Editing calcium carbonate is an inorganic compound and the main component of limestone, with the molecular formula CaCO3.

Relative molecular massCalcium oxide (CaO) accounts for 56.03% of 100.09%.

Carbon dioxide（CO2）accounts for 43.97%.

Industrial calcium carbonate, edible calcium carbonate, pharmaceutical calcium carbonate. Types of industrial calcium carbonate: heavy calcium carbonate (heavy calcium).

Activated calcium carbonateActive calcium, light calcium

Nano calcium carbonateNanocalcium

Heavy Calcium CarbonateThe meaning of 的: Heavy calcium carbonate, also known as ground calcium carbonate (GCC), is produced by directly crushing natural materials such as calcite, limestone, chalk, and shells using mechanical methods. Its sedimentation volume (1.1-1.9mL/g) is higher than that produced by chemical methods.

Light Calcium CarbonateVolume of settlement (2.4-2.8mL/g) is small, hence it is called heavy calcium carbonate.

Activated calcium carbonateThe modified calcium carbonate is obtained by modifying ordinary calcium carbonate, so as to achieve the dual purposes of filling and modifying in composite material products. These modifications include modifications to the crystalline form, particle size, particle size distribution, and surface properties of calcium carbonate to improve its overall performance.

Light Calcium CarbonateLight calcium carbonate is also known as.

Precipitated calcium carbonate(PCC), abbreviated as PCC, is produced by chemical processing methods. Due to its sedimentation volume (2.4-2.8mL/g) being higher than that produced by mechanical methods.

Heavy calcium carbonateThe volume of settlement (1.1-1.9mL/g) is large, so it is called light calcium carbonate.

Nanometer calcium carbonateNanometer calcium carbonate is an important new inorganic salt product prepared by using non-metallic mineral limestone as raw material and synthesizing nano-powder technology by precipitation method, with a particle size of 10-100nm. Due to its small particle size and good activity, it is a new type of inorganic material.

Calcium carbonate is one of the most widely used fillers in the rubber industry. Large amounts of calcium carbonate filled in rubber can increase the volume of its products and save on expensive.

Natural rubberBy filling rubber with calcium carbonate, the tensile strength, tear strength, and wear resistance can be significantly increased.

Plastic Industry: Calcium carbonate can play a role as a skeleton in plastic products, which has a great impact on the dimensional stability of plastic products, can also improve the hardness of products, and enhance the surface gloss and smoothness of products. Due to the whiteness of calcium carbonate being above 90%, it can also replace expensive white pigments.

The paint industry: Calcium carbonate is also widely used in the paint industry, with a dosage of more than 30% in thick paint.

Water-based paintIndustry: Calcium carbonate is more widely used in the water-based paint industry, it can prevent paint from settling, easy to disperse, good gloss and other characteristics, the dosage in water-based paint is 20-60%.

In addition, calcium carbonate plays an important role in the paper industry, ensuring the strength and whiteness of paper at a low cost. In the products of the cable industry, it can provide a certain level of insulation.
