摘　　要：探讨了用间隔取液法延长化学镀镍液使用寿命。通过分析ρ(亚磷酸钠)和沉积速率随每周期取出部分溶液的关系得出结论,当取液量大于化学镀镍溶液15%时,化学镀镍溶液中的有害离子均不超过其临界质量浓度,化学镀镍溶液可以连续工作并能维持较高的镀速。A method of extracting bath out periodically for extending the life of electroless nickel plating bath was discussed.Relationships between phosphite accumulation,deposition rate and amount of the bath extracted out periodically were analyzed.Results showed that when extracting amount of the bath was greater than 15%,harmful ions would not exceed their critical concentration and the bath could work continuously with high deposition rate.
