| 摘 要： | 为了防止超细Al粉在空气中腐蚀变质,通过电动搅拌机的机械作用,在球形Al粉表面进行了硬脂酸钠包覆改性.通过正交实验获得了改性工艺的最佳条件：反应16 h,m（C17H35COONa）/m（Al）为3%,Al粉与硬脂酸钠需分别溶于无水乙醇,然后将Al粉溶液加入硬脂酸钠溶液中.采用SEM,IR和XPS对包覆样品进行分析,结果表明：改性后的铝粉形成了稳定的胶囊结构,复合粉体的耐腐蚀性明显提高. |

| Abstract: | To improve superfine aluminum(Al) powders' anti-corrosion in air,the aluminum powders are coated with sodium stearate through mechanical action.The best reaction condition is investigated by orthogonal test: time is 16 h;m(C17H35COONa)/m(Al) is 3%;superfine aluminum and sodium stearate should be dissolved in ethanol respectively,then puts superfine aluminum solution into sodium stearate solution.Encapsulated samples are analyzed and characterized by SEM,IR and XPS.It is found that the composite powder is mi... |
