Specific use of heavy calcium carbonate is as follows: Generally used as a filler, but also widely used man-made floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, building supplies, food, pharmaceutical, textile, feed, toothpaste and other household chemical industry, as a filler serve to increase the volume of products, reduce production costs. For rubber, rubber to increase the volume and improve the processing of rubber, from the semi-reinforcing or reinforcing effect, and can adjust the hardness of the rubber 1. rubber industries with heavy calcium rubber - rubber with heavy calcium carbonate powder: 400 mesh, whiteness: 93%, calcium carbonate: 96%) of calcium carbonate is one of the largest amount of large filler used in the rubber industry. Among a large number of calcium carbonate filler in the rubber, can increase the volume of their products, and saving expensive natural rubber, thus greatly reducing costs. Calcium carbonate filled rubber, can be higher than that of pure rubber vulcanizate tensile strength, tear tear strength and abrasion resistance. 2. plastics industries with heavy calcium plastic - plastic masterbatch, masterbatch with heavy calcium carbonate (heavy calcium) 400 mesh, require high temperature heating whiteness unchanged ore structure for large crystal calcite, calcium carbonate content : 99%, Whiteness: 95%), calcium carbonate plastic skeleton can play a role in the stability of plastic the size of a large role, but also improve the hardness of products and increase surface gloss products and surface smoothness. Because whiteness of calcium carbonate in 90 or more, you can also replace expensive white pigment. 3. The paint industry with heavy calcium paint - paint with heavy calcium carbonate (heavy calcium) or 1000 800 mesh mesh, whiteness: 95% calcium carbonate: 96%) the amount of calcium carbonate in the paint industry are more large, for example in an amount of thick paint more than 30%. 4. waterborne coatings industries with heavy calcium carbonate aqueous coating heavy (heavy calcium) or 1000 800 mesh mesh, whiteness: 95% calcium carbonate: 96%) of calcium carbonate in aqueous coatings industry uses more extensive make no settlement paint, easily dispersed, good gloss and other characteristics, in the amount of 20-60% water-based paint and paper industries with heavy calcium 5. papermaking heavy calcium carbonate (heavy calcium): 325 mesh, white Degree Requirements: 95%, calcium carbonate content: 98% calcium carbonate important role in the paper industry to ensure the strength and whiteness of the paper, and low cost 6. construction industry (dry mortar, concrete) with heavy calcium powder. Mortar with heavy calcium carbonate (heavy calcium) 325 mesh, whiteness requirements: 95%, calcium carbonate content: 98%) of calcium carbonate in the concrete in the construction industry plays an important role not only reduce production costs, but also increase. 7. toughness and strength fireproof ceiling industry heavy calcium carbonate heavy fireproof ceiling (heavy calcium): 600 mesh, whiteness requirements: 95%, calcium carbonate content: 98.5%) of calcium carbonate in the production of fireproof ceiling process needs to be used, can improve product whiteness and brightness, but also increase the fire resistance 8. artificial marble artificial marble industries with heavy calcium carbonate with a heavy (heavy calcium): 325 mesh, whiteness request : 95%, calcium carbonate content: 98.5% pure and free of impurities) calcium carbonate has been widely used in the production of artificial marble flooring 9. drilling industries with heavy drill floor with heavy calcium carbonate (heavy calcium): 400 mesh, Whiteness requirements: 95%, calcium carbonate content: 98.5% pure and free of impurities) of calcium carbonate can be used in the drill floor industry, to increase the product's whiteness and tension, improve the toughness of products, reduce production costs.
