摘要
总结了电缆桥架锌铁合金电镀的工艺配方,探讨了镀前镀后处理、主盐和导电盐含量、线槽悬挂方式、阴极电流密度、镀液pH值、添加剂ZF、ZF A、ZF B含量等因素对电缆桥架电镀质量的影响。提出了镀液的维护方法。生产实践证明:当主盐ZnCl2和导电盐KCl的质量浓度分别为55～75g/L和230g/L、阴极电流密度为0 8～1 2A/dm2、镀液的pH值为4～5、添加剂ZF A含量为0 2～0 4kg/t、ZF含量为1 5～2kg/t、ZF B含量为0 7～1kg/t时,采用锌铁合金电镀,不但解决了电缆桥架电镀难的问题,而且其防护性能高于普通镀锌。
The process formula of Zn-Fe alloy plating for cable bridge rack was summerizied. The influences of factors including pretreatment and post-treatment, the concentrations of major salt and conductive salt, the ways of hanging line tank, cathode current density, pH value of bath, additive content of ZF、ZF-A and ZF-B, etc, on the plating quality of cable bridge rack were discussed. The bath maintenance method was presented. The production practice proves that under the condition of 55～75 g/L of ZnCl_2, 230 g/L of KCl, 0.8～1.2 A/dm^2 of cathode current density, 4～5 of pH value, 0.2～0.4 kg/t of ZF-A additive, 1.5～2 kg/t of ZF additive and 0.7～1 kg/t of ZF-B additive, the Zn-Fe alloy plating process can solve the difficult problem of plating cable bridge rack, and the deposits obtained by the process has higher protective ability than the deposits by common zinc plating.
