Heavy calcium powder for rubber industry Heavy calcium carbonate powder for rubber-rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%) Calcium carbonate is one of the largest fillers used in the rubber industry. A large amount of calcium carbonate is filled in rubber, which can increase the volume of its products and save expensive natural rubber, thereby greatly reducing the cost. When calcium carbonate is filled in rubber, it can obtain higher tensile strength, tear resistance than pure rubber sulfide. Crack strength and wear resistance.
Heavy calcium powder plastic for plastic industry - heavy calcium carbonate powder (heavy calcium powder) for plastic masterbatch and color masterbatch is 400 mesh, the whiteness is required to remain unchanged after high temperature heating, the ore structure is large crystal 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, and can also improve the hardness of products, and improve the surface gloss and surface of products. Flatness. Because the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments.
Heavy calcium powder paint for paint industry - heavy calcium carbonate for latex paint (heavy calcium powder) 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 96%) The amount of calcium carbonate in the paint industry is also large, For example, the dosage in thick paint is more than 30%.
Heavy calcium powder for water-based coatings industry Heavy calcium carbonate for water-based coatings (heavy calcium powder) 800 mesh or 1000 mesh, whiteness: 95%, calcium carbonate: 96%,) calcium carbonate is more widely used in the water-based coating industry, It can make the coating not settle, easy to disperse, good gloss and other characteristics. The dosage in water-based coating is 20-60%.
Heavy calcium powder for papermaking industry Heavy calcium carbonate for papermaking (heavy calcium powder): 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98% Calcium carbonate plays an important role in the paper industry. It can ensure the strength and whiteness of the paper degree and low cost.
