As a new ultra-fine solid powder material, nano-calcium carbonate industry has huge development potential

Nano calcium carbonate, also known as ultrafine calcium carbonate and ultrafine calcium carbonate, is a new type of ultrafine solid powder material. Nano-calcium carbonate has the advantages of fine particle size, high whiteness, good compatibility, and good optical properties, and has been widely used in many fields.

my country’s nano calcium carbonate industry started in the 1980s and entered the stage of industrial production in the late 1980s. Non-freezing method, multi-stage spray carbonization method, intermittent carbonization method, hypergravity method, internal circulation carbonization tower preparation method, jet absorption method, etc. are the main preparation methods of nano calcium carbonate in my country. The intermittent carbonization method can be subdivided into two categories: intermittent stirring carbonization method and intermittent bubbling carbonization method. Currently, the intermittent bubble carbonization method is the most widely used preparation method in the world. In recent years, with the efforts of leading companies, some of my country’s nano-calcium carbonate production technologies have reached overseas advanced levels.

The raw material of nano calcium carbonate is limestone. my country is the country with the richest limestone resource reserves in the world, accounting for nearly 70.0% of the world’s total reserves. my country’s limestone resources are concentrated in Shandong, Anhui, Henan, Hebei, Shaanxi, Gansu and other places. According to statistics from the Geological Center of the former National Building Materials Administration, the distribution area of ​​limestone in my country reaches 438,000 square kilometers, accounting for approximately 5.0% of the country’s land area. In recent years, under the influence of national environmental protection policies and deepening supply-side structural reforms, my country’s high-quality limestone production has declined. Insufficient supply of raw materials has caused the price of nano-calcium carbonate to continue to grow.

According to the “2022-2027 China Nano Calcium Carbonate Industry Market In-depth Research and Development Prospects Forecast Report released by Synaptics Industrial Research Center It shows that nano calcium carbonate has a wide range of applications, including paper industry, medical and health care, rubber products, coatings and plastics. Nano-calcium carbonate accounts for a large proportion of the plastic market and can be used as a plastic regulator and enhancer. Nano-calcium carbonate has excellent dispersion, can improve the aging resistance and impact strength of plastics, and is widely used in PVC film materials. Benefiting from strong downstream demand, my country’s nano calcium carbonate market demand continues to grow. In 2021, my country’s nano calcium carbonate market demand will reach 4.928 million tons, a year-on-year increase of 10.2%.

In terms of market competition, the world’s well-known nano-calcium carbonate suppliers include France’s Solvay Group, Pfizer of the United States, British Imperial Chemical Industries Group ICI, Japan’s Maruo Calcium Co., Ltd., etc. All the above companies have achieved large-scale production of nano-calcium carbonate and occupy a dominant position in the global market.

my country’s nano calcium carbonate industry started late, and the production enterprises are small in scale, including Shandong Shanda Technology Co., Ltd., Zhejiang Changshan Jinxiong Co., Ltd., etc. Industry analysts said that at present, overseas brands occupy a monopoly position in my country’s nano calcium carbonate market, and local companies are in urgent need of It is necessary to accelerate the layout of the industrial structure and improve the level of production technology in order to further increase the localization rate of the industry.
