Calcium powder Calcium powder is commonly known as: limestone and stone powder. It is a compound with the chemical formula CaCO3. It is alkaline, basically insoluble in water and soluble in acid. It is a common substance on the earth and is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of animal bones or shells.
Classification of calcium powder
Calcium powder can be divided into: heavy calcium powder, light calcium powder, gray calcium powder, active calcium powder, etc.
Calcium Uses of powder
The role of calcium powder in various industries:
1. Calcium powder for rubber industry
Rubber - Calcium powder for rubber: 400 mesh, Whiteness: 93, calcium content: 96) Calcium powder is one of the most widely used fillers in the rubber industry. Calcium powder is filled in large amounts in rubber, which can increase the volume of its products and save expensive natural rubber, thus greatly reducing costs. Filling calcium powder into rubber can obtain higher tensile strength and tear resistance than pure rubber vulcanization. cracking strength and wear resistance.
2. Value of calcium powder used in the plastics industry
Plastics - 400 mesh calcium powder for plastic masterbatch and color masterbatch requires that the whiteness remains unchanged after high-temperature heating and the ore structure is large. Crystalline calcite calcium powder content: 99, whiteness: 95). Calcium powder can play a skeleton role in plastic products, which has a great effect on the dimensional stability of plastic products. It can also improve the hardness of the products and improve the quality of the products. Excellent surface gloss and surface smoothness. Since the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments.
3. Calcium powder for paint industry
Paint-calcium powder for latex paint 800 mesh or 1000 mesh, whiteness: 95, calcium carbonate: 96) Calcium powder in the paint industry The dosage is also larger, for example, the dosage in thick paint is more than 30.
4. Calcium powder for water-based coatings industry
Calcium powder for water-based coatings 800 mesh or 1000 mesh, whiteness: 95, calcium powder: 96,) Calcium powder for water-based coatings industry It has a wider range of uses. It can make the coating non-settling, easy to disperse, and has good gloss. The dosage in water-based coatings is 20-60.
5. Calcium powder for papermaking industry
Heavy calcium powder for papermaking 325 mesh, whiteness requirement: 95, calcium powder content: 98 Calcium powder plays an important role in the papermaking industry. It can ensure the strength and whiteness of the paper, and the cost is low.
6. Calcium powder for the construction industry (dry mortar, concrete)
Calcium powder for dry mortar is 325 mesh, whiteness requirement: 95, calcium powder content: 98) Calcium powder is used in concrete in the construction industry Important role. It can not only reduce production costs, but also increase the toughness and strength of products.
7. Calcium powder for fire-resistant ceiling industry
Calcium powder for fire-resistant ceilings 600 mesh, whiteness requirements : 95, calcium powder content: 98.5) Calcium powder is needed in the production process of fireproof ceilings, which can improve the whiteness and brightness of the product, and the fireproof performance will also be increased.
8. Used in the artificial marble industry Calcium powder
Calcium powder for artificial marble is 325 mesh, whiteness requirement: 95, calcium powder content: 98.5, pure and without impurities) Calcium carbonate has been widely used in artificial marble production
9. Calcium powder for floor drilling industry
Calcium powder for floor drilling industry is 400 mesh, whiteness requirement: 95, calcium powder content: 98.5, pure and without impurities) Calcium powder can be used in floor drilling industry. Increase the whiteness and tensile strength of the product, improve the toughness of the product, and reduce production costs.
