硬脂酸钠/Al复合粒子的改性研究
Modification Research of Sodium Stearate/Al Composite Powder
摘要
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(AI) 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 micro-capsule structure, and its anti-corrosion is insignificantly improved than raw Al powder.关键词
