China import superfine calcium carbonate and activated calcium carbonate

Light CalciumCarbonate is also called the precipitated calcium carbonate (referred to as PCC). Precipitated calcium carbonate is prepared by chemical processing method. Due to the settling volume (2.4-2.8mL/g) than its production by mechanical methods of heavy calcium carbonate sedimentation volume (1.1-1.9mL/g), and is therefore called the light calcium carbonate.

Light calcium carbonate as raw material in chemical industry, it is not only a good filler, and is an ideal modifier, and is widely used in rubber, plastics industry: industry, papermaking industry, building materials industry etc.. Our existing light calcium carbonate production more than 300 enterprises, of which more than 98% products for large particles, particle size distribution is not uniform in the ordinary calcium carbonate or ordinary calcium carbonate. Superfine calcium carbonate and calcium carbonate as compared with ordinary calcium carbonate in the particle size and surface activity have a large degree of improvement. At the present stage, our country light calcium carbonate, especially high-grade calcium carbonate in short supply, heavy dependence on imports, therefore, has a very broad market development and production of high grade light calcium carbonate and activated calcium carbonate products, has great social benefit and economic benefit.

At present, in the domestic market, light calcium carbonate and the price for 600-700 yuan / ton. Superfine light calcium carbonate demand the light calcium carbonate in the production of light calcium carbonate production accounted for only about 5% of the total. Calcium carbonate superfine light calcium carbonate products accounted for half of all the developed countries in Europe and America's consumption, but also professional rate is high. The average annual demand of light calcium carbonate at home to 15% of the rate of growth, especially of superfine calcium carbonate is mainly from Japan, American to import, the average price of $680 per ton. Active calcium is a kind of excellent material modification agent, the domestic market price in 1000 yuan / tons, have good market prospects.
