【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。更多还原

【Abstract】 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.更多还原
