摘　　要：以淄博某地煤系硬质高岭土为试样,进行矿物成分和含量的分析,研究了煅烧过程中煅烧温度、入料粒度、保温时间、添加剂用量以及成球直径对白度的影响,探讨了添加剂的增白机理,分析了煅烧产品的结构、性能。在1025℃煅烧2 h并添加2wt%的NaCl作为氯化剂氯化增白煅烧高岭土,试样煅烧白度达到了90%以上,满足橡胶填料、涂料的需要,为淄博某地区煤系硬质高岭土的开发利用提供了依据。Making a coal measure hard kaolin which is in Zibo as samples, and analysis of the mineral composition and content, calcinations temperature calcinations process, the feeding size, holding time, the amount of additives as well as into a ball diameter of whiteness in to explore the additive whitening mechanism to analyze the structure of the calcined product performance. Taking 2wt% of NaCl in 1025 ℃ calcined 2 h and add chloride whitening calcined kaolin as the chlorinating agent, the specimen calcined whiteness reached above 90% , to meet the needs of the rubber filler, coating, for a region in Zibo coal measure hard kaolin the development and utilization of the basis.
