化学镀镍反应中止问题原因分析

Analysis of the Causes for Interruption in Electroless Nickel Plating Reactions

针对化学镀镍过程中反应中止的问题,进行了生产过程中各个因素的分析排查,对可能造成反应中止的因素进行了机理分析,确定了问题产生的原因并对故障进行了复现,制定了控制措施。结合现场生产情况,建立故障树,逐一分析、排查,对可能造成问题的底事件进行机理分析。通过对故障现象的复现,验证问题定位的正确性。针对问题原因,完成措施的制定。对问题的分析过程,给化学镀镍工程实践过程中的故障分析提供了明晰、快捷的解决方法。

In addressing the issue of reaction interruption during electroless nickel plating,a comprehensive analysis of various factors during production were conducted.Mechanisms potentially leading to the reaction interruption were scrutinized.The cause of the problem was identified and the fault was replicated.Control measures were subsequently established.Combined with the on-site production situation,a fault tree had been established to analyze and troubleshoot one by one,and to analyze the mechanism of the bottom event that may cause problems.Through the reproduction of the fault phenomenon,verify the correctness of the problem location.According to the cause of the problem,complete the formulation of measures.The analysis process of the problem provides a clear and fast solution to the fault analysis method in the practice of electroless nickel plating engineering.
