摘要
利用干式高能球磨法制备片状锌粉,采用正交实验法研究不同球磨助剂配方对球磨锌粉中位粒径d50、松装密度和水面遮盖率的影响,确定最佳复合助剂配方。结果表明,在加入硬脂酸、棕榈酸、硬脂酸锌、聚乙二醇的最佳质量分数分别为2.5%、0.3%、0.3%、0.1%的最优复合助剂配方条件下,制得片状锌粉颗粒的中位粒径d50为13.12μm,松装密度为0.934 8 g/cm3,水面遮盖率为2 280.2 cm2/g;过程中没有新相产生,锌粉颗粒得到有效包覆。
The flake zinc powders were prepared by dry high energy ball milling. The orthogonal test was applied to investigate the effect of different additives formula on median particle size d50, apparent density and water surface covering of the milled flake zinc powders. The optimum formula of composite additives was identified. The results show that the best mass fractions of stearic acid, palmitic acid, zinc stearate and poly-ethylene glycol are 2.5%, 0.3%, 0.3% and 0.1%. The median particles size d50, apparent density and water surface covering was 13.12 μm,0.934 8 g/cm3, 2 280.2 cm2/g. There is no new phase generated and the milled flake zinc powders are coated effectively.
