use
Heavy calcium carbonate is usually used as filler, and also widely used in artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other daily chemical industries. As a filler, it can increase the product volume and reduce the production cost. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role and adjust the hardness of rubber.
The function of heavy calcium powder in arrangement;
1. Heavy calcium powder for rubber industry
Rubber-Heavy calcium carbonate powder for rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%) Calcium carbonate is one of the most widely used fillers in rubber industry. Filling a large amount of calcium carbonate in rubber can increase the volume of its products and save expensive natural rubber, thus greatly reducing the cost. Filling calcium carbonate in rubber can obtain higher tensile strength, tear strength and wear resistance than pure vulcanized rubber.
2. The application value of heavy calcium in plastic industry.
Heavy calcium carbonate powder (heavy calcium carbonate powder) for plastic masterbatch and color masterbatch is 400 mesh, and the whiteness is required to remain unchanged after heating at high temperature. The ore structure is large crystalline calcite with 99% calcium carbonate content and 95% whiteness. Calcium carbonate can play the role of skeleton in plastic products, which has a great effect on the dimensional stability of plastic products, and can also improve the hardness, surface gloss and smoothness of products.
3. Heavy calcium powder for coating industry
Heavy calcium carbonate for coating (heavy calcium powder)-latex paint with 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 96%). The consumption of calcium carbonate in coating industry is also very large, for example, in thick paint, the consumption is above 30%.
4. Heavy calcium powder for waterborne coatings industry
Heavy calcium carbonate (heavy calcium carbonate powder) for water-borne coatings has a mesh size of 800 or 1000, with whiteness of 95% and calcium carbonate of 96%. ) Calcium carbonate is widely used in waterborne coatings industry, which can make coatings have the characteristics of non-sedimentation, easy dispersion and good luster, and its dosage in waterborne coatings is 20-60%.
5. Heavy calcium powder for paper industry
Heavy calcium carbonate for papermaking: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98%. Calcium carbonate plays an important role in paper industry, which can ensure the strength and whiteness of paper and has low cost.
6. The construction industry (dry mortar, concrete) with heavy calcium powder
325 mesh heavy calcium carbonate for dry mortar (heavy calcium carbonate powder, whiteness requirement: 95%, calcium carbonate content: 98%) plays an important role in concrete in construction industry, which can not only reduce production costs, but also increase the toughness and strength of products.
7. Heavy calcium powder for fire ceiling industry
Heavy calcium carbonate (heavy calcium carbonate powder) for fireproof ceiling: 600 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%) Calcium carbonate is needed in the production process of fireproof ceiling, which can improve the whiteness and brightness of products and improve the fireproof performance.
8. Heavy calcium powder for artificial marble industry
Heavy calcium carbonate for artificial marble (heavy calcium carbonate powder): 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, pure and free of impurities) Calcium carbonate has been widely used in artificial marble production at present.
9. Heavy calcium powder for drilling platform industry
Heavy calcium carbonate for floor tiles (heavy calcium carbonate powder): 400 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, pure and free of impurities) Calcium carbonate can be used in floor drilling industry to increase the whiteness and tension of products, improve the toughness of products and reduce production costs.
