Light Calcium Carbonate

Light Calcium Carbonate also named precipitated calcium carbonate. The manufactured process of light calcium carbonate is achieved by chemical synthesis. Because its settlement volume (2.4-2.8mL/g) is larger than that of the heavy calcium carbonate produced by mechanical method (1.1-1.9mL/g), it is called light calcium carbonate.

Light Active Calcium Carbonate Characteristics

* The particle size is smaller than that of heavy calcium carbonate; Better fineness.

* Better whiteness.

* Less impurities; high purity.

* The appearance is mainly spindle or spherical shape.

* Good dispersion

Light Calcium Carbonate Main Applications

Light calcium carbonate has a wide range of functions and can be used in the following industries:

1)The rubber industry: calcium carbonate is one of the earliest largest filling agents used in the rubber industry.

2)Plastics industry: calcium carbonate play a great role in the stability of plastic products, improve the hardness of the products, and improve the surface gloss and surface smoothness of the products.

3)Paint industry

4)Water-based coatings industry

For the special cement products, Oreworld trade (Tangshan) co., Ltd. includes calcium aluminate cements (CA cement) and calcium sulfoaluminate cements (CSA cement/CSA binder). The CSA cement is more and more imported by GRC manufacturers and dry mix mortars manufactures because of its higher performance compare to the Portland cement such as fast setting time, rapid hardening and high strength in 3 days. It is also widely used in bridge building the highway building and cold weather concreting.
