摘要
为了充分开发利用各种高岭土资源，将精选、去杂、漂白后的不同产品，根据其性质的差异，采用三种不同的办法进行深加工：（１）将填料级产品进行煅烧，微粉化和表面改性处理，加工成功能性填料；（２）焙烧后的高岭土与盐酸在一定条件下反应，加工成聚合氯化铝和白炭黑；（３）利用不适合作高级造纸涂料的高岭土合成４Ａ沸石。
In order to fully develop and utilize various kaolin resources,three deeper processing methods are adopted according to different characteristics of kaolin products resulted from beneficiation,impurity removal and bleaching.They are:(1) Roasting the fillergrade products followed by micropulverizing and surface improving to produce functional fillers;(2)Carrying out the reaction of roasted kaolin with hydrochloride acid under certain conditions to produce aluminium polychloride and white carbon black;(3)Synthesizing 4A zeolite with kaolin which can not be used as a high-grade paint for paper-making.
