本文介绍三种季铵化芳香醛化合物的合成途径,并应用它们为无氰碱性镀锌的添加剂。镀液的阴极极化曲线与锌镀层的扫描电子显微图均表明:这些化合物对获得光亮均匀锌镀层起很好的作用.镀液中加入适量优洛托平,可扩大电镀电流密度范围。
This article describes the synthesis of three quaternary aromatic aldehyde compounds, and apply them as cyanide-free alkaline zinc additives. The cathodic polarization curve of the bath and the scanning electron micrograph of the zinc coating both show that these compounds play a very good role in obtaining a bright and uniform zinc coating.
