中国地质大学(武汉)研制成超微重晶石粉深加工工艺。用该工艺加工的超微重晶石粉,其硫酸钡含量达到99％,中位粒径<0.7μm,白度>98(R457％),优于ISO(国际标准)3262技术标准的粉体,也优于目前最先进的德国萨其宾公司的产品。该工艺生产的超微重晶石粉具有较好的增白、改性和防腐蚀、防辐射、耐酸碱等功能,是生产高级涂料、塑料、橡胶、造纸、高级玻璃等产品的极好填充料,具有广阔的开发前景。 China University of Geosciences (Wuhan) developed ultra-micro barite powder processing technology. The superfine barite powder processed by the process has the advantages of more than 99% of barium sulfate content, a median grain size of less than 0.7 μm, and a whiteness of more than 98% (R457%), which is better than that of the ISO (International Standard) 3262 technical standard powder, Also superior to the most advanced German Sahibin company’s products. The process produces superfine barite powder has better whitening, modification and anti-corrosion, radiation, acid and other functions, is the production of advanced coatings, plastics, rubber, paper, glass and other products excellent filling Material, with broad development prospects.
