As we all know, in the production process of using bright acid copper additives, the content of chlorine ions in the plating solution is too high or too low will affect the quality of the plated layer. So how do we determine the content of chloride ions in the plating solution during production?
1. When the brightness of the plating layer is poor, in the replenishment of mixed brightening agent or distribution of brightening agent components after replenishment of the brightness of the plating layer does not significantly improve, and the plating layer of the phenomenon of high-current area of the blossom, low-current area of the foggy deposition, the plating solution may be less than the content of chloride ions 30mg / L, can be replenished with 0.1ml / L of hydrochloric acid. When the bright and smooth performance of the plated layer is significantly improved after the addition, it means that the content of chloride ion is too low, and it is necessary to analyze the amount of hydrochloric acid after the addition of the appropriate amount.
2. When the plating layer in the high current area of the bright leveling performance is good, while the low current area is very poor, the content of sulfuric acid is normal, in the adjustment of the brightening agent and replenishment of the opening agent and filler after the effect is not obvious, it may be the plating solution in the chlorine ions are too much, then can be appropriate to replenish the zinc powder of 0.5 ~ 1.0g / L in order to remove excess chlorine ions in the plating solution.
