摘　　要：本文对石英型尾矿的预处理进行了研究 ,通过对改性尾矿和石蜡混合体系的粘度测定 ,得到了表面改性剂不同添加量对粉体表面状态影响曲线 ,确定了表面改性剂的最佳用量 ,另外 ,还对表面改性产品的性能进行了测定 ,最后还做了将改性尾矿用于聚乙烯塑料制品中的应用实验。According to the principles of surface chemistry,surface modification of quartz tailings powder and it's application in plastics are studied. The curve of viscosity against the additive amount are obtained,and the product properties also are examined.The modified product is applied in plastics of PE as additives. From the fact it is concluded that modification agent not only can reduce the surface energy of tailings powder but also can increase the tensile strength of plastics.
