【摘要】 兖矿北海高岭土目前生产的产品原始烧成白度为76%～81%。本文中采用的是烧成白度为80.1%的产品为研究对象,通过磁选、酸洗、过筛、还原漂白除铁等方式提高产品的烧成白度,并对不同的试验研究和反应机理进行探讨。除铁增白试验结果表明,高岭土烧成白度可提高4%以上。更多还原

【Abstract】 The original burnt whiteness of Beihai kaoline is 76%~81%,the whiteness of subject investigated is 80.1%.Through the magnetic separation,acidwashing,sieving,reducing bleaching deferrization,the whiteness of product can be improved,and the reaction mechanism and charging system discussed.The experiments made great effect on whiteness,and the whiteness of kaoline add to four percentage points.更多还原
