| 2. | Firstly , the mechanism of the preparation of superfine quartz powder with ball mill is studied in this article , based on nature of quartz material , griffith ' s strength theory and the crush theory of planetary ball mill . the problem of granulation during the process of the preparation of superfine quartz powder is studied minutely . and proposed increasing dispersant and disperser medium to restrain granulation , and dispersing use ultrasonic after milled
首先,本文结合石英材料的基本物性,以格里菲斯强度理论和行星式球磨机的粉碎原理为基础,研究了球磨法制备超细石英粉体的机理,同时对粉石英制备过程中的团聚问题及其控制作了细致的研究,提出粉磨过程中增加分散剂和分散介质来抑制团聚,粉磨后采用超声法进行分散,并确定了最佳分散剂、分散介质的用量和最佳超声分散时间。 |
