Ground calcium carbonate, referred to as heavy calcium, is made by grinding natural carbonate minerals such as calcite, marble, limestone. The shape of heavy calcium carbonate is irregular, the particle size difference is large, and the particles have a certain edge, the surface is rough, the particle size distribution is wide, the particle size is large, the average particle size is generally 1~10μm.
1.Heavy calcium powder used in rubber industry is one of the most used fillers in rubber industry.
2.The heavy calcium powder used in the plastic industry can play a skeleton role in the plastic products, which has a great effect on the stability of the size of the plastic products, and can also improve the hardness of the products, and improve the surface luster and surface flatness of the products.
3.The heavy calcium powder used in the paper industry can ensure the strength and whiteness of paper, and the cost is low.
4.Heavy calcium carbonate plays an important role in concrete in the construction industry. It can not only reduce the production cost, but also increase the toughness and strength of the product.
5.Heavy calcium carbonate has been widely used in the production of artificial marble.
6.Heavy calcium carbonate is more widely used in the water-based coating industry, which can make the coating non-settling, easy dispersion, good luster and other characteristics, and the amount of water-based coating is 20-60%.
Qualification Certificate
Choose transport tools that have good tightness and corrosion resistance to avoid scattering of calcium carbonate.
Calcium carbonate packaging should be sealed to ensure integrity, avoid damage to the packaging, and moisture, pollution, and other conditions. Calcium carbonate storage should not allow direct sunlight and a high-temperature environment; the best place is a dry, well-ventilated warehouse.
