Superfine calcium carbonate activity

　　Calcium carbonate is an important inorganic chemical product, and is widely used as a filler for rubber, plastic, paper, paint, toothpaste, etc. due to its low price, wide raw materials and non-toxicity. The amount of calcium carbonate in paper is about 11 million tons per year in the world, accounting for more than 60% of the total amount of fillers, and about 1.5 million tons of plastics. Recently, scientists have found that ultra-fine calcium carbonate has a reinforcing effect and can be used as a coating for anti-sanding of automobile chassis. Japan, the United States and the United Kingdom are international leaders in the development, production and application of ultra-fine calcium carbonate. China has been conducting research on ultra-fine calcium carbonate since the 1980s, and there is still a big gap with the world's advanced level. According to the data in recent years, due to the extremely wide range of applications of ultra-fine heavy calcium, the demand in the market is also growing. In view of the technological development of various industries, higher requirements are imposed on calcium carbonate production, and micro and super have appeared successively. A new variety of fine, active and high-purity light calcium carbonate. In particular, as the paper industry grows at an annual rate of around 8%, the demand for light calcium carbonate increases at a rate of 15% per year.

　　Based on the above situation, it is expected that the demand of the world calcium carbonate market will continue to grow, the sales of low-end products will be smooth, the demand for high-end products will be strong, and the international market price will remain at the current price level. If Chinese manufacturers can self-discipline, prevent a large number of low-priced competitive sales. For the added value of low-end products, it is expected that the world market price of calcium carbonate should be further improved due to the increase in energy prices and transportation costs.
