During the process of preparing the tin plating solution (containing acid tin plating brightener), why does turbidity occur? In this article, we will analyze it.
Sulfosalicylic acid is insoluble in water
This factor has been discussed in our previous articles. This time, we will provide some additional information. That is, trial mixing should be conducted. Under normal circumstances, the prepared plating solution should be clear. However, sometimes the prepared plating solution appears cloudy. This is caused by the quality issue of sodium sulfite. It could be due to the manufacturing process, or it might be due to the long storage period after leaving the factory.
Therefore, before the electroplating factory prepares the large tank plating solution, as a supplier of acid tin plating brightener , Bigely suggests that a trial run should be conducted in a small tank following the normal preparation procedure. If no abnormalities are observed in the prepared plating solution, then the large tank can be prepared. Otherwise, further tests should be conducted on the quality of the ferrous sulfate tin to determine the possible causes.
Requirements for stirring during the preparation of the plating solution
To ensure that all components in the plating solution are uniform and consistent, thorough stirring should be carried out during the solution preparation process. Do not be negligent.
