The main use of calcium carbonate products
Rubber industry: Calcium carbonate is used in rubber industry the largest one big filler. Among a large number of calcium carbonate filled in the rubber, increase the volume of its products, and save expensive natural rubber, thereby greatly reducing costs. Calcium carbonate filled rubber, sulfide rubber, can be higher than that of pure tensile strength, tear strength and wear resistance.
Plastics industry: calcium carbonate in the plastic products can play a role in skeleton, the size of the plastic products have a significant role in stability, but also improve the hardness of products and improve product surface gloss and surface smoothness. As the calcium carbonate in more than 90% brightness, but also to replace expensive white pigment.
Paint industry: calcium carbonate content in the paint industry is also large, is as thick paint in the amount of 30%.
Waterborne Coatings Industry: calcium carbonate in the water-based paint industry used more widely, can paint no settlement, dispersion, and good gloss characteristics, water-based paint in the amount of 20-60%.
In addition, calcium carbonate, an important role in the paper industry, can guarantee the strength and whiteness of paper, and lower costs. In the cable industry products, insulation can play a role.
Market prospects of calcium carbonate
According to the data analysis, by 2010, China's market demand for calcium carbonate:
Plastics industry: demand for heavy calcium carbonate is expected to reach 220,000 tons.
Paper industry: the need for ultra-fine heavy calcium carbonate is about 600 thousand tons.
Rubber industry: the total demand will reach 20 million tons.
Paint: superfine heavy calcium carbonate needs about 60,000 tons.
Adhesives and Sealants: will consume about 550,000 tons of calcium carbonate, heavy calcium carbonate superfine amount of activity will reach 11 million tons.
