根据振动混沌控制和应力释放原理,首次提出了一种制备纳米片状锌粉的新设备和新方法。试验研究证明,经过1 h振动加工后,150g中值粒度为1 0mm的球状雾化锌粉基本上都成了薄片状,薄片的厚度在10～15μm之间,直径方向尺度分布在20～100nm之间,这一转变过程的电力消耗只有0.12kW·h。延长研磨时间可使厚度继续减小,直径-厚度比继续增大,并使颗粒形状更加规则化和均匀化。
According to the principle of vibration chaos control and stress release, a new equipment and a new method for preparing nanosheet zinc powder are proposed for the first time. Experimental studies have shown that after 1 h of vibration processing, 150g of spherical powder atomized zinc powder having a median particle size of 10 mm basically becomes flaky, the thickness of the flakes is between 10 and 15 μm, and the diameter direction is distributed between 20 and 100 nm The power consumption in this transition is only 0.12 kW · h. Prolonging the grinding time can continue to reduce the thickness, diameter - thickness ratio continues to increase, and make the particle shape more regular and uniform.
