Wholesale calcium whiteness 95% to 98% calcium

It is common on Earth calcium substance found in the aragonite, calcite, chalk, limestone, marble, travertine and other rocks. It is also the main ingredient of animal bones or shells. 2 calcium free calcium can be divided into: remake shape calcium, light calcium, calcium and other active remake of heavy calcium carbonate is irregular, large particle size difference, and the particles a certain angular, rough surface, a wide particle size distribution, the larger particle size, the average particle diameter is generally 1 ~ 10μm. Heavy calcium carbonate in its original average particle diameter (d) is divided into: coarse grinding calcium carbonate (> 3μm), finely ground calcium carbonate (1 ~ 3μm), ultra-fine calcium carbonate (0. 5 ~ 1μm of heavy calcium carbonate . Powder characteristics: a particle of irregular shape; b wide particle size distribution; c larger particle size present, calcium carbonate has been widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants,... household chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, putty, carpet packaging, pharmaceuticals, foods (such as chewing gum, chocolate), feed, and its role are: increased product volume, reduce costs, improve processability (e.g. to adjust the viscosity, rheological properties, curing properties), improved dimensional stability, a reinforcing or semi-reinforcing, improved printing performance, improved physical properties (such as heat resistance, matting property, abrasion resistance, flame retardance , whiteness, gloss), etc. Light Gaifen widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants, household chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax , putty, carpet packaging, pharmaceuticals, foods (such as chewing gum, chocolate), feed, and its role are: increased product volume, reduce costs and improve the processing performance (such as adjusting the viscosity, rheological properties, curing properties), improved dimensional stability sex, reinforcing or semi-reinforcing, improve printing performance, improve the physical properties (such as heat resistance, matting, abrasion resistance, flame resistance, whiteness, gloss) etc. The active calcium calcium. to promote bone and teeth calcification, maintain normal nerve and muscle excitability, reducing capillary permeability due to calcium deficiency for the prevention and treatment of chronic diseases caused by the use of the role of calcium in calcium 3 rows given in: 1 and rubber industries with calcium powder rubber - rubber calcium: (400 mesh, whiteness: 93% calcium content: 96%), calcium is one of the largest large filler used in the rubber industry to fill in a lot of calcium. Among rubber, increase the volume of its products and save expensive natural rubber, thus greatly reducing costs. Gaifen filled rubber, can be higher than that of pure rubber sulfide tensile strength, tear strength and abrasion resistance Sexual 2, the plastics industry with calcium numerical plastic masterbatch, masterbatch with calcium powder 400 mesh, it requires high temperature heating whiteness unchanged structure of large crystalline calcite mineral calcium content: 99%, Whiteness: 95% ), calcium powder in plastic skeleton can play a role in the stability of plastics size plays a significant role, but also improve the hardness of products, and improve the surface gloss and surface smoothness of the article. Since calcium carbonate whiteness above 90, it can also replace expensive white pigment. 3, the paint industry with calcium powder paint, latex paint with calcium powder 800 mesh or 1,000 head, whiteness: 95% calcium carbonate: 96%, the amount of calcium in the paint industry is large, such as the amount in the thick paint 30% or more. 4, waterborne coatings industries with aqueous coating calcium calcium 800 mesh or 1,000 head, whiteness: 95%, calcium: 96% calcium in waterborne coatings industry more versatile, can paint without sedimentation, easy dispersion, good gloss characteristics, in an amount of 20-60% water-based paint. 5, the paper industry with a heavy paper with calcium calcium 325 mesh, whiteness requirements: 95% calcium content: 98%, the important role of calcium in the paper industry, to ensure the strength and whiteness of the paper, and the cost low. 6, the construction industry (dry mortar, concrete) with calcium powder dry mortar with calcium powder 325 mesh, whiteness requirements: 95% calcium content: 98%, calcium concrete construction industry plays an important role. It can not only reduce production costs, but also increase the toughness and strength of the product. 7, fireproof ceiling industry fireproof ceiling calcium calcium 600 mesh, whiteness requirements: 95% calcium content: 98.5%, calcium fireproof ceiling in the production process need to use, you can improve product whiteness and brightness, and fire resistance will increase. 8, artificial marble artificial marble industry with calcium calcium 325 mesh, whiteness requirements: 95% calcium content: 98.5% pure and free of impurities, calcium carbonate has been widely used in the production of artificial marble. 9, floor drilling industry with the drill floor calcium with calcium powder 400 mesh, whiteness requirements: 95% calcium content: 98.5% pure and free of impurities. Calcium can be used in the drill floor industry, to increase the product's whiteness and tension, improve the toughness of products, reduce production costs. Common specifications 4 calcium calcium specifications are: 100 mesh 200 mesh 325 mesh 400 mesh 600 mesh 800 mesh Head 2500 4000 1250 and other projects.
