| 摘 要： | 用自行设计的限制式雾化喷嘴为核心的雾化装置，研究了在喷嘴关键结构参数（输液管的直径、喷嘴狭缝尺寸、喷射角等）一定的条件下，雾化压力及熔融温度对液锌的雾化效果的影响。结果表明，当雾化介质为Ｎ２，压力为０．４０～０．５０ＭＰａ，液锌温度为６５０℃时，液锌可以获得较好的雾化效果，通过显微镜观察和电镜扫描，发现制备的锌粉大部分为不规则形状。

| Abstract: | On an atomization unit with confined type nozzle,a study on the influence- of gas pressure and molten metal temperature on the atomization of molten zinc was carried out. The results showed that effective atomization occurs if nitrogen is 0. 40-0. 50MPa and molten metal temperature is 650C. Microscopic and SEM observation indicated that zinc powder was mainly irregular in shape- |
