采用干法研磨方法对钨粉粉末进行预处理,操作时间30min。该方法细化效果明显,粒度曲线分布收窄。但是进一步观察发现,粉末团聚现象加剧。
The dry grinding method is used to pretreat the tungsten powder powder, and the operation time is 30 minutes. The refining effect of this method is obvious, and the distribution of the particle size curve is narrowed. However, further observation revealed that the powder agglomeration phenomenon has increased.
