Calcium carbonate (CaCO₃) is a common chemical compound found globally as rocks like limestone and chalk, as well as in eggshells and pearls. It serves two primary roles: as an oral dietary supplement for bone health, and as a widely used over-the-counter antacid to neutralize stomach acid.

Feature

Heavy and light calcium carbonate can be added into detergent, toothpaste, mainly as a soft abradant to play the role of soft friction. Products include specific calcium for detergent, toothpaste grade light calcium carbonate and 1500mesh special purposed calcium; The average diameter of particles is 57μm, Whiteness≥ 95, pH value is about 9, can meet the national standard of toothpaste grade calcium carbonate (GB/T2317-97).

Uses

(1) Coating 
Calcium carbonate can be used as paint filler, with concentrated distribution of particles, high Whiteness; 
It can be used as a body filler in the coating to increase its dispersion or from the skeleton in the products, it is a good filler and white pigment. 
In oil paint, it can enhance the deposition and permeability on the primary surface of primer. Calcium carbonate can improve product performance, reduce product costs and improve processing performance, Heavy calcium carbonate is one kind of micro-fine calcium carbonate made of high pure and white Calcite in wet grinding method. 

(2). Papermaking 
Calcium carbonate can widely be used in the paper industry, offer filling and coating effects in the paper, with an excellent dispersion, and can increase the fill volume, improve product performance and processing and mechanical properties, etc. It can significantly reduce paper costs, increase the whiteness of paper, improve printing performance and optical properties of paper, so that it decrease the cost of products. 
Calcium carbonates one kind of micro-fine calcium carbonate made of high pure and white Calcite in wet grinding method. 

(3). Sealant 
Calcium carbonate is widely used as the filler in adhesives and sealants. Wet grinding calcium carbonate has good fluidity and dispersion for it is processed by special coupler: Can improve product performance, reduce product costs and improve processing performance. Coupler processed calcium carbonate has better dispersion, thus it can be dispersed in adhesive evenly and improve the quality of products.
