摘 要:  

采用湿法表面包覆将5种单一表面改性剂按不同的比例包覆于铜锌粉末的表面,测试包覆后铜锌粉末的润湿性、漂浮性以及印刷光泽度,并且分析了改性剂对铜锌粉末润湿性和漂浮性的影响机理。结果表明,经      1%月桂酸钠包覆的铜锌粉末的润湿性降低最多,经2%吐温-80包覆的铜锌粉末的漂浮性升高最多,2%吐温-80对铜锌粉末润湿性的降低和漂浮性的升高都有较大的改善,包覆后的铜锌粉末印刷光泽度由原来的54.4提高到75.5,基本可以满足印刷对铜锌粉末的要求。

Abstract:Five kinds of single surfactant were coated on the surface of bronze powder by wet method in different proportions, the wettability, floating property and gloss of the coated bronze powders were measured, and the influence mechanisms of the surfactants on the wettability and floating property of the bronze powders were analyzed as well. The results show that the wettability of the bronze powders coated by 1% sodium laurate has the largest decrease and the floating property of the bronze powders coated by 2% tween-80 has the largest increase. 2% tween-80 has significant improvement on the decrease of the wettability and the increase of the floating property of bronze powders. The gloss of the coated bronze powders increases from 54.5 to 75.5, thus can meet the printing requirements for bronze powders.
