Calcite powder
Heavy calcium carbonate, referred to as heavy calcium, is a white powder processed with high-quality calcite as its raw material. Its main component is CaCO3, heavy calcium has high whiteness, good purity, soft hue and stable chemical composition. Therefore, heavy calcium is a good filler commonly used in industry. Heavy calcium is generally used as a filler, and is also widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. To increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of rubber.
The role of heavy calcium powder in various industries:
1. Heavy calcium powder for rubber industry
Heavy calcium carbonate powder for rubber 400 mesh, whiteness: 93%, calcium carbonate: 96%, calcium carbonate is one of the fillers used in the rubber industry. A large amount of calcium carbonate is filled in the rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing costs. Calcium carbonate is filled into the rubber, which can obtain higher tensile strength, tear strength and wear resistance than pure rubber sulfide.
2. Heavy calcium powder for plastic industry
Heavy-duty calcium carbonate powder (heavy calcium powder) for plastic masterbatch and color masterbatch is required to be 400 meshes. The whiteness is unchanged after high temperature heating. The ore structure is large crystalline calcite, calcium carbonate content: 99%, whiteness: 95% Calcium carbonate can play a skeleton role in plastic products, which has a great effect on the dimensional stability of plastic products. It can also increase the hardness of products, and improve the surface gloss and surface smoothness of products. Because calcium carbonate has a whiteness above 90, it can also replace expensive white pigments.
3. Heavy calcium powder for paint industry
Heavy calcium carbonate (heavy calcium powder) 800 mesh or 1000 mesh for paint and latex paint, whiteness: 95%, calcium carbonate: 96%, the amount of calcium carbonate in the paint industry is also large, such as the amount of thick paint More than 30%.
4. Heavy calcium powder for water-based paint industry
Heavy-duty calcium carbonate (heavy calcium powder) for water-based coatings is 800 or 1000 mesh, whiteness: 95%, calcium carbonate: 96%, calcium carbonate is more widely used in water-based coatings industry, can make the coating not settle, easy to disperse, Good gloss and other characteristics, the amount of water-based paint is 20-60%.
5. Heavy calcium powder for the paper industry
Papermaking heavy calcium carbonate (heavy calcium powder) 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98% Calcium carbonate plays an important role in the paper industry. Can guarantee the strength and whiteness of the paper, and the cost is low.
6. Heavy calcium powder for the construction industry (dry powder mortar, concrete)
Heavy calcium carbonate (heavy calcium powder) 325 mesh for dry powder mortar, whiteness requirement: 95%, calcium carbonate content: 98%, calcium carbonate plays an important role in concrete in the construction industry. Not only can the production cost be reduced, but also the toughness and strength of the product can be increased.
7. Heavy calcium powder for fireproof ceiling industry
Fireproof ceiling with heavy calcium carbonate (heavy calcium powder) 600 mesh, whiteness requirement: 95%, calcium carbonate content: 98.5%, calcium carbonate needs to be used in the production process of fireproof ceiling, can improve the whiteness and brightness of the product And the fire resistance will also increase.
8. Heavy calcium powder for artificial marble industry
325 mesh of heavy calcium carbonate (heavy calcium powder) for artificial marble, whiteness requirement: 95%, calcium carbonate content: 98.5%, pure and free of impurities. Calcium carbonate has been widely used in artificial marble production.
9. Heavy calcium powder for floor tile industry
Floor tiles with heavy calcium carbonate (heavy calcium powder) 400 mesh, whiteness requirements: 95%, calcium carbonate content: 98.5%, pure and free of impurities, calcium carbonate can be used in the floor tile industry to increase the whiteness and Tension, improve the toughness of products and reduce production costs.
10. Heavy calcium powder for feed industry
The feed industry uses heavy calcium carbonate (heavy calcium powder) 325 mesh, whiteness requirement: 95%, calcium carbonate content: 99%, pure and free of impurities. Calcium carbonate can increase the calcium content in feed and improve feed quality.
