研究了真空蒸发冷凝制备超细锌粉的规律，提出了一种经济合理的激冷机制．实验证明，通过真空蒸发冷凝制备超细锌粉，可以降低蒸发温度、节约能源，所得锌粉为六方晶形，形状规则，粒度小于１μｍ，且较为均匀，金属锌的挥发速率受蒸发温度与真空度的影响较大，而且在真空条件下具有提纯物料的作用，超细锌粉的粒度受控于真空度、温度、冷凝器滚筒的转速三个主要因素
The law of ultra-fine zinc powder prepared by vacuum evaporation and condensation was studied, and an economical and effective chilling mechanism was proposed. Experiments show that the ultrafine zinc powder can be prepared by vacuum evaporation and condensation, which can reduce the evaporation temperature and save energy. The obtained zinc powder has a hexagonal crystal shape and has a regular shape with a particle size of less than 1 μm and is uniform. The volatilization rate of zinc metal is affected by the evaporation temperature and the degree of vacuum Of the larger, but also under the vacuum conditions with the role of purification of the material, the size of ultrafine zinc powder controlled by the vacuum, temperature, condenser drum speed of three major factors
