稳定剂对锡盐电解着色液性能的影响

Effect of Stabilizing Agents on Properties of Tin Salt Electrolytic Colouring Solution

本文通过对比实验,初步研究了几种常用稳定剂对锡盐电解着色液性能的影响.认为:络合剂影响稳定性的本质是对Sn^(2+)、Sn^(4+)络合平衡的影响,同时通过影响阴极界面反应来实现对分散能力及着色重现性的影响;抗氧化剂遏制Sn^(2+)氧化而稳定槽液,促进阴极还原过程而提高着色重现性,但对分散能力影响不明显.

Effect of several common used stabilizing agents on the properties of tin salt electrolytic colouring solution was investigated preliminary through a lot of contrast experimemts. The experimental results suggest that complexing agents influence the stability of colouring solution through affecting the complexing equilibrium between Sn^(2+) and Sn^(4+), and influence the throwing power and colouring reproducibility by affecting cathode surface reactions. Antioxidants stabilize the colouring solution by preventing Sn^(2+) from oxidation and increase the colouring reproducibility by promoting cathodic reduction processes. Their effect on throwing power is not notable.
