Nano calcium carbonate is an important inorganic chemical products, compared to ordinary calcium carbonate fine particles, large surface area, surface activation rate, higher whiteness, etc., in many application areas can play enhanced by tough role, to improve product usability and appearance, and it can partially replace the expensive, such as silica and other raw materials, the product cost reductions, quality greatly, so calcium carbonate appeared, showed a wide range of applicability and strong market demand, in paint, plastics, rubber, adhesives, paper, ink, paint, cosmetics and pharmaceutical and food industries have a wide range of uses.
At present, about 30% of nano calcium carbonate for rubber products, plastic products for 30%, 20% for paper, 20% for coatings and other products. As the production falls short of a year had to import large quantities of imported about 10 million tonnes (including nano-, sub-nanometer products calcium carbonate products). In recent years, as China's rapid economic development, especially in coatings, plastics and other industrial products of the upgrading, the nano-level will continue to increase demand for calcium carbonate, the same time, the paper industry production Gongyi the Buduan progress will also promote our nano the development of calcium carbonate. Estimated that by 2008, China's demand for the nano calcium carbonate will reach about 400,000 tons, when the time is still unable to meet the actual production output requirements, still need to import large quantities.
In recent years, although China's Nanometer calcium carbonate production capacity increased rapidly, but due to my nano calcium carbonate product of the unitary and functional deficiencies, poor marketing, many enterprises, the actual output is not large, the actual production can not meet the domestic demand exacerbated the growing import market in China, resulting in imports are high value products, prices high, while exports are mostly low-value products, the situation, which explains my nano calcium carbonate products are still high-end market better prospects. It should be noted, with the number of continuous production plant put into operation, increasing market competition will. Therefore, Our country existing production enterprises to expand production capacity and should constantly improve technology advances, pay attention to continuously improve product quality, reduce production costs; active and relevant industry research organization, Jinkuai develop and produce Shige Gezhongyongtu of domestic series of nano calcium carbonate needed to increase our production level of calcium carbonate, solve the problem of imports; enhance product promotion efforts, improve product competitiveness; use of Chinese enterprises in the technology and cost advantages in expanding the domestic market At the same time, actively explore the international market, so that the technological advantages of China's nano calcium carbonate into economic benefits for the industry to create more space for development. In addition, foreign manufacturers should be concerned about the new production process at any time in research and development trends of new technology to speed up the development of nano calcium carbonate so as to ensure that our steady and orderly development of the health industry.
