Electroplating production line manufacturers of electroplating equipment passivation in the large area of the lower edge of the workpiece to see a light "sauce trace", this phenomenon is mainly caused by the following two reasons:

First, after the passivation of the workpiece is not clean, the surface water film contains passivation solution;

Second, the drying method is defective! Can be used natural drying method, the workpiece surface containing the passivation solution of the water film gradually flow to the edge of the aggregation, to be gathered in the evaporation of water

After leaving the salt color of soy sauce.

There is the film adhesion is poor, which is mainly passivation film caused by the aging process, the process of a greater impact on the quality of the film!

Electroplating production line manufacturers experience, passivation film after 40 ~ 45 ℃ aging and no aging treatment compared to the aging treatment after the protective performance and wear resistance are significantly improvedhigh.

Electroplating production line manufacturers also found that the aging process before the surface of the workpiece if the water droplets, then after aging treatment, the passivation film in all aspects of performance will be far below its

His position, this is because in high temperature conditions, this area of acid droplets will break under the film, for this, before the aging of the workpiece surface must first absorb the water, And then aging!
