General situation of talcum for interested individual
Talcum is a mineral of hydrous magnesian silicate with a sheet structure. It has relatively high insulation and thermoinsulation properties, high melting point and strong oil-adsorbing performance. It is mainly applied as a filler, coating in papermaking industry and pulp pitch-controlling agent. And then it can be used for filling materials in roofing products (asphalt felt, roofing paper board, asphalt shingle, roofing board). It can also be used for batch material in ceramics, filler in coating (paint) and white pigment, filling material for rubber, electric cable and plastics and insulation material. In addition, it has also wide application in textile, cosmetics, pharmaceutical industries, carving and sculptural arts and so on.
As early as 5,000~6,000 years ago talc had already been used in sculpture in China. The application of talc as a drug can be traced back to more than 2,000 years ago. In 763 A.D. talc was firstly exploited in the Longsheng mine, Guangxi. Since 1890 the recent Chinese talc industry had gone through all kinds of twists and turns. In 1949 the production of talc was only 3,848 tons. Since 1949, the talc industry in China has had a major development. Up to the 1970s three large talc production bases taking Haicheng in Liaoning, Longsheng in Guangxi and Laizhou in Shandong as the centers respectively and a lot of medium-sized and small talc mines have been set up. In 1997 there were 138 talc mining-processing enterprises in the whole country with an annual production of 4.07 million tons of industrial talc raw materials.As the professional manufacturer of complete sets of mining machinery, such as ore processing plant,cement making plant, Henan Hongxing is always doing the best in products and service.limestone rotary kiln:http://www.hxjq-crusher.com/23.html.ore separating line:http://www.hxjqchina.com/.
