Anhui Qingyang builds a cluster of non-metallic new materials of heavy calcium, Anhui Qingyang builds a cluster of non-metallic new materials of heavy calcium, Anhui Province, February 25, 2005 recently, Qingyang County, Anhui Province, based on the local resources, location and other basic advantages that even a few socks can't be cut with sharp scissors, is striving to build China (Qingyang) industrial cluster base of non-metallic new materials of heavy calcium

the leading products of the industrial cluster base of non-metallic new materials of heavy calcium carbonate are heavy calcium carbonate powder and its downstream extension products. Jianshan, Dongshan and LAILONGSHAN, located in Nanyang Township, Qingyang County, are rich in heavy calcium carbonate resources, with reserves of 300 million tons. They are the first in Anhui Province, with good whiteness (generally greater than 93 degrees), high grade (calcium carbonate content of more than 99%), and extremely low impurity content. They are high-quality raw materials for processing ultra-fine heavy calcium powder for paper, high-grade plastics and coatings

at present, there are two main processing methods of ultra-fine heavy calcium carbonate in the world, namely, dry production process and wet production process. The dry production process has low cost and simple process flow. When the first phase of the project is put into operation, it is generally used to produce products below 3000 tons; The process flow of wet production is complex, and the products produced are generally products below 2 microns or up to nano scale. There are enterprises settled in Qingyang heavy calcium non-metallic new material base that adopt two process and technology schemes. Through investment promotion, the county has successfully introduced more than 40 heavy calcium powder processing enterprises, planned and designed to produce heavy calcium powder new materials with a total scale of about 3million tons, and a total planned investment of about 2.5 billion yuan
