Product Description

Factory supply CaCO3 ground or heavy calcium carbonate 
1.Product description of calcium carbonate
 
Feature :White fine powder without smell and taste. Its relative density is 2.5-2.7, hardly insoluble in water and enthanol, but soluble in lower density acid.(acetic acid, lower density hydrochloric acid and nitric acid).It is difficult to solubilize in lower density vitriol.
Application:

(1)Rubber industry:
Calcium carbonate was the earliest filler used in the rubber industry. It can enlarge the capacity in the rubber products,for saving the cost. It also enhance the tensile strength, abrasion and tearing strength.

(2)Plasticindustrial :
In plastic products, keeping stablity of theproducts, strengthen the products,
keeing surface smoothly

(3)Painting:
PCC is innocuous, white color, and has good stability, as the filler in paints, avoid the paint settlement, easy get dispersed,make good glossiness

(4)Papermaking:
Whitening the paper, and as the fller, can reducing the pulp for saving the cost.
