The calcium carbonate powder factory believes that heavy calcium carbonate has characteristics such as a wide range of raw material sources, high whiteness, low oil absorption value, good applicability, and low price. It can save resin in the fields of plastics, rubber, and adhesives, and save pulp in the paper industry, increasing the opacity and ink absorption of paper. With these characteristics, heavy calcium carbonate has become a rapidly developing inorganic non-metallic mineral powder material in the past 20 years.
The calcium carbonate powder factory believes that with the development and changes in demand in related application fields or downstream industries, China's heavy calcium carbonate has developed from fine powder to ultrafine powder and ultrafine active powder. As the market demand for ultrafine powders increases and quality requirements rise, the proportion of ultrafine heavy calcium carbonate in total output is continuously increasing, currently reaching about 40% of the total output of heavy calcium carbonate.

On the other hand, due to the increasing requirements for the filling performance and filling amount of heavy calcium carbonate fillers in polymer-based composite materials such as plastics, rubber, adhesives, and artificial stone, the proportion of surface-modified or active heavy calcium carbonate products is increasing rapidly year by year.

The calcium carbonate powder factory believes that after years of development, heavy calcium carbonate has been widely used in fields such as artificial boards, rubber, plastics, papermaking, coatings, inks, cables, building materials, food, medicine, textiles, feed, and toothpaste.

The calcium carbonate powder factory believes that compared to leading foreign enterprises, domestic heavy calcium carbonate companies in China are generally smaller in scale and have weaker competitiveness. However, in recent years, the overall competitive strength of domestic enterprises has been continuously improving, and a number of strong local enterprises have emerged. The market for mid-to-low-end products is almost occupied by domestic enterprises, and the product market is gradually breaking the monopoly of foreign enterprises or their companies in China.

However, overall, the current application of heavy calcium carbonate in China is mainly focused on primary products, with an oversupply of ordinary products and few high value-added products, which cannot meet the demands of the world market and the Chinese market, leading to a high price of imported ultrafine heavy calcium carbonate products. The real application value of heavy calcium carbonate lies in its deep-processed products.

The calcium carbonate powder factory believes that calcium carbonate is divided into light calcium carbonate and heavy calcium carbonate. The characteristics of calcium carbonate, such as color, particle size, surface properties, dispersibility, rheology, thixotropy, and crystal form, can be manually controlled. Calcium carbonate has high chemical purity, strong chemical inertness, and good thermal stability, and it does not decompose below 400 degrees. In addition, calcium carbonate also has advantages such as low oil absorption rate, low hardness, small wear value, non-toxic, odorless, and good dispersibility.

The calcium carbonate powder factory believes that due to these special properties, the application of calcium carbonate has developed rapidly and has been widely used in industrial and agricultural fields, such as rubber, plastics, papermaking, coatings, paints, inks, cables, medicine, fertilizers, feed, food, sugar production, textiles, glass, ceramics, sanitary products, sealants, adhesives, pesticides and pesticide carriers, flue gas desulfurization, water treatment, and other environmental protection aspects. The uses and weight of light calcium carbonate are mainly used in fields such as papermaking, plastics, synthetic rubber, food, food coloring, medicine, adhesives, and sanitary products. In recent years, light calcium carbonate has been widely used because it can enhance the performance of certain materials.
