水解用活性铝粉的制备工艺研究
Research on the Process of Preparing Activated Aluminum Powder for Hydrolyzation
【摘要】 金属铝粉活性是制约单质铝发生水解反应的关键因素。对活化过程中影响活化铝粉性能尤其是粒度性能的各种因素如雾化气体压力、转盘转速、金属熔体过热度等进行了实验研究。实验发现,雾化气体压力对雾化粉体粒度的影响呈倒抛物线关系,存在一个临界压力,当压力接近此值时雾化粉体达到最细;转盘转速越高,金属熔体过热度越大,活化粉体粒径越细。
【Abstract】 The key factor that controls aluminum hydrolyzing is activity of the aluminum powder. The pivotal factors,pressure of atomization gas,rotation speed of turnplate and degree of superheat of the melted aluminium,are analysed in detail. The experiment results show that pressure and particle size have a reverse parabola relationship. There is acritical pressure, when pressure is near this value, the particle size distributing is finest. The higher the rotation speed of the turnplate and the degree of superheat, the more finer the particle size.
