摘要
DE-81(3)型碱性镀锌工艺具有单位面积电流密度大、生产效率高,镀液对金属杂质的容忍量大等优点。介绍了该镀锌工艺的生产流程和工艺配方,及其钝化工艺配方;各成分的用量范围及其作用。详细说明了镀液维护的要点。采用DE-81(3)型碱性镀锌工艺大批量处理多品种、尺寸不一、形状各异的零件,经过多年的生产实践和抽样检测结果,镀层外观、附着力、厚度和耐盐雾试验均达到国家标准。
DE-81(3) alkaline zincate electroplating process has the advantages of high current density per unit area, high productivity, high tolerance to metal impurities in plating bath, etc. Procedure and formula of the zinc plating process, and its chromating formula were all introduced. The key points of bath maintenance were described in detail. Mass production for different kinds, size and shape of particles were completed with DE-81(3) alkaline zincate electroplating process. For years of production and sampling determination results, the appearance, adhesion, thickness and salt spray test of the zinc deposit meet all the requirement of Chinese standards.
