The modified calcium carbonate (active calcium carbonate) market is highly competitive and my country has raw material advantages

Modified calcium carbonate, also known as activated calcium carbonate, refers to calcium carbonate obtained by activating the surface of heavy calcium carbonate, light calcium carbonate or nano calcium carbonate. Modified calcium carbonate appears as white powder with no special odor. It has the advantages of good chemical stability, non-toxicity, large specific surface area, and easy coloring. It is widely used in food processing, synthetic rubber, synthetic plastics, construction engineering, medicine and other fields.

Modified calcium carbonate is mostly made of heavy calcium carbonate, light calcium carbonate or nano calcium carbonate as the base material. my country is a major producer and consumer of calcium carbonate, and its output has maintained a long-term growth trend. In 2022, my country’s heavy calcium carbonate output will reach 32.167 million tons, light calcium carbonate output will reach 6.126 million tons, and nano calcium carbonate output will reach 1.816 million tons. At present, heavy calcium carbonate is widely used in the production process of modified calcium carbonate in my country, and the advantages of raw materials have laid a good foundation for the development of the industry.

The main preparation methods of modified calcium carbonate include high-energy surface modification, mechanochemical modification, inorganic surface treatment, polymer surface modification, and organic surface modification. The mechanochemical modification method has the advantages of easy parameter control and simple production process, and is suitable for large-scale production; the organic surface modification method is the mainstream preparation method of modified calcium carbonate, which uses quaternary ammonium salts, fatty acids and phosphates. Surface modifier is used to modify the surface of calcium carbonate to produce finished products. It has the advantages of mild reaction conditions and good finished product quality.

According to the “2023-2028 China Modified Calcium Carbonate (Activated Calcium Carbonate) Industry Market In-depth Research and Development Prospects Forecast Report》shows that modified calcium carbonate is usually used in food processing, synthetic rubber, synthetic plastics, construction engineering, medicine and other fields. In the field of food processing, modified calcium carbonate can be used as a food additive to improve the taste of food; in the field of synthetic rubber, modified calcium carbonate can be used as a rubber filler to improve the wear resistance and tensile properties of rubber; in synthetic plastics In the field of plastics, modified calcium carbonate can be used as a filler for plastics such as low-density polyethylene, high-density polyethylene, polypropylene, and polyvinyl chloride.

There are many modified calcium carbonate manufacturers in my country, and the market competition is fierce. Zhejiang Calcium, Zhechuang Chemical, Zhaojun Chemical, Changhong Hi-Tech, Orchid Nano, Tianci Calcium, Tianshi Nano, etc. are the main manufacturers of modified calcium carbonate in my country. Changhong Hi-Tech is my country’s leading enterprise in modified calcium carbonate and is currently actively promoting the construction of a high-end modified calcium carbonate project with an annual output of 1 million tons.

Industry analysts said that thanks to the sufficient supply of raw materials and the improvement of technological maturity, the output and quality of modified calcium carbonate in my country have continued to improve. The development trend of the industry continues to improve. Benefiting from the accelerated development of downstream industries such as food processing and synthetic plastics, my country’s modified calcium carbonate market demand is increasingly strong. At present, there are many players in my country’s modified calcium carbonate market, and companies with high-end modified calcium carbonate production capabilities will gain more market share in the future.
