PRODUCT DESCRIPTION

Heavy calcium carbonate, referred to as heavy calcium, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler with high chemical purity, high inertness, not easy to react chemically, good thermal stability, no decomposition below 400°C, high whiteness, low oil absorption, low refractive index, soft, dry, no crystal water, low hardness, low wear value, non-toxic, tasteless, odorless, good dispersibility and other advantages.

PRODUCT USE

1. Rubber Industry

Rubber-Heavy calcium carbonate powder for rubber: 400 mesh, whiteness: 93%, calcium carbonate: 96%) Calcium carbonate is one of the largest fillers used in the rubber industry.

2. Plastic industry

Plastic-Heavy calcium carbonate powder (heavy calcium powder) 400 mesh for plastic masterbatch and masterbatch, requiring whiteness to remain unchanged after high temperature heating, ore structure is large crystal calcite, calcium carbonate content: 99%, whiteness: 95%), calcium carbonate can play a skeleton role in plastic products, 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 smoothness of products. Since the whiteness of calcium carbonate is above 90, it can also replace expensive white pigments.

3. Paint industry

Paint-Heavy calcium carbonate (heavy calcium powder) 800 mesh or 1000 mesh for latex paint.

4. Water-based paint industry

Heavy calcium carbonate (heavy calcium powder) for water-based paint is 800 mesh or 1000 mesh. Calcium carbonate is more widely used in the water-based paint industry. It can make the paint not settle, easy to disperse, and have good gloss.

5. Papermaking industry

Heavy calcium carbonate (heavy calcium powder) for papermaking: 325 mesh, whiteness requirement: 95%, calcium carbonate content: 98% Calcium carbonate plays an important role in the papermaking industry. It can ensure the strength and whiteness of paper, and the cost is relatively low.
