【摘要】 用还原和络合的方法对高岭土进行漂白,有效降低高岭土中铁的含量,并通过综合分析,采用正交实验设计方法优化选择出最佳的漂白工艺条件,为生产白度达85%的高岭土提供一种最简便有效的方法。更多还原

【Abstract】 The Kaolin was bleached with reduction and complexing ways according to its physical and chemical properties. The iron content of Kaolin was reduced effectively for increasing the whiteness. The best bleaching conditions was established by using the orthogonal-mode experimentation.The experimental result provides the most convenient and effective way for producing kaolin with 85% whiteness.更多还原
