1、镀液组成及操作流程： 

      原料及操作                    范围                     * 

              FH—595开缸盐                   280—330 g/L                  300 g/L 

              FH—595铬盐                     130—170 g/L                  150 g/L 

              FH—595稳定剂                   50—70 ml/L                   65 ml/L 

             FH—595湿润剂                   3—5  ml/L                    4 ml/L 

              FH—595黑铬1#                   10—50 ml/L                   30 ml/L 

              FH—595黑铬3#                   5—15  ml/L                   15 ml/L 

              三价铬                           20—24 g/L                    22 g/L 

              PH                               2.5—3.0                      2.5 

              温度                            30—40℃                      32℃    

              比重                             24—26                         25 

              阴极电流密度                   10—30A/dm²                    15A/dm² 

              阳极电流密度                   3.5—5.5A/dm²                  4.5A/dm² 

              阳极材料                       三价铬专用阳极 

              过滤                           连续过滤 

              搅拌                           中等程度机械式或空气搅拌 

              加热                           采用纯钛加热管 

   2、设备要求： 

        a)镀槽：PVC、PP、ABS、聚烯衬槽 

        b)阳极：采用专用阳极或钛钩 

        C)温度控制：采用钛加热管及钛冷却装置 

        d)整流器：要求配置安培小时积累计 

        e)自动添加器 

        f)阴、阳极导电排使用钛包铜材或包胶 

              3、工艺对色泽的影响：

            开缸盐                             高低对颜色没影响，只提供导电

             铬盐                              高颜色浅

             稳定剂                            高对镀层较光亮，低易发黄

             湿润剂                            高低对颜色没影响

             黑铬1#                            高色泽变深黑，过量走位变差，颜色不均匀

             黑铬3#                            高色泽变黄，走位提高，过量颜色不均匀易变色

             PH值                              低颜色黑 ，高颜色浅

             温度                               高低对色泽没有影响

        4、添加量：1000A/h

           1#:500ml

             3#:250ml
