Calcium Powder
Introduction
Calcium powder, commonly known as: limestone and stone powder, is a compound whose main component is CaCO3, which is weakly alkaline and soluble in water and acid.
Classification
Calcium powder can be divided into: heavy calcium powder, light calcium powder, active calcium powder, flue gas desulfurization calcium powder, superfine calcium carbonate, etc.
Applications
1. Calcium powder for rubber industryCalcium powder for rubber-rubber: 400 mesh, whiteness: 93%, calcium content: 96%, calcium powder is one of the largest fillers used in the rubber industry. A large amount of calcium powder is filled in the rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing the cost. Calcium powder is filled into rubber to obtain higher tensile strength, tear strength and abrasion resistance than pure rubber vulcanizates.
2. Calcium powder value for plastic industryPlastic masterbatch and color masterbatch use calcium powder 400 mesh. The whiteness is required to remain unchanged after high temperature heating. The ore structure is large crystal calcite. The content of calcium powder: 99%, the whiteness: 95%. Calcium powder can play a role in plastic products. A skeletal effect has a great effect on the dimensional stability of plastic products, and can also increase the hardness of the products, and improve the surface gloss and surface smoothness of the products. As the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments.3. Calcium powder for paint industryCalcium powder 800 mesh or 1000 mesh for paint and latex paint, whiteness: 95%, calcium carbonate: 96%, the amount of calcium powder in the paint industry is also large, for example, the amount in thick paint is more than 30%.
