Calcium carbonate is an inorganic compound, commonly known as limestone, limestone, stone powder, marble, etc. Main ingredients: calcite is a compound, chemical formula is CaCO3, neutral, basically insoluble in water, soluble in hydrochloric acid.
Rubber Industry: calcium carbonate is one of the largest fillers used in rubber industry. Calcium carbonate filled in rubber can increase the volume of its products and save expensive natural rubber, thus greatly reducing the cost. The tensile strength, tear strength and wear resistance of calcium carbonate filled rubber are higher than those of pure rubber sulfide.
Plastic Industry: calcium carbonate can play a skeleton role in plastic products, which has a great effect on the dimensional stability of plastic products, and can also improve the hardness of products, and improve the surface gloss and smoothness of products. Because the whiteness of calcium carbonate is more than 90%, it can also replace the expensive white pigment.
Paint Industry: the amount of calcium carbonate in the paint industry is also large, such as the amount in heavy paint is more than 30%.
Water Based Coating Industry: calcium carbonate is more widely used in the water-based coating industry, which can make the coating not settle, easy to disperse, good gloss and other characteristics. The dosage of calcium carbonate in water-based coating is 20-60%.
In addition, the important role of calcium carbonate in the paper industry can ensure the strength and whiteness of the paper, and the cost is low. In the cable industry products, can play a certain role in insulation.
