铝合金锡盐体系电解着色液稳定剂的研究

A Study of the Stabilizer in Tin Based Electrolytic Colouring Bath for Anodized Aluminium Alloys

探讨了稳定铝合金锡盐体系电解着色槽液的几种方法.试验证明,某些酚类、胺类化合物对防止Sn^(2+)氧化,阻止Sn^(2+)和Sn^(4+)水解,维持槽液长期稳定,不变浑浊,效果良好.

Several methods to stabilize tin based electrolytic colouring bath were described. It was proved through experiment `s that some phenolic and amine compounds have better effeets on inhibiting oxidation and hydrolysis of Sn^(2+), keeping the solution clear for a longer period.
