Selection of plating solution for electric heating tubes

The selection of plating solution and process parameters is a necessary work before electroplating the product. The plating solution and the process conditions used must be determined by the requirements of the product. At present, there are many processes that can be used, and different formulas and process conditions can be easily found. The first step in selecting the formula and supporting process of the plating solution is to meet the quality requirements of the product in a targeted manner, and secondly, to consider the possible implementation environment and conditions.

Products require electroplating, usually for decorative protection or to enhance their functionality. Regardless of the purpose, the plating layer must be a uniform and complete covering, which is the most basic requirement. If the shape of the plated part is complex, or has small inner holes, depressions, or blind holes, or the material and surface are very special, the electroplating process must be carefully studied and analyzed before determining to meet these special conditions. It is clearly necessary to consider whether the plating solution can have sufficient macroscopic and microscopic dispersion capabilities.

The formulas for electroplating solutions can generally be divided into two categories. According to the morphology of ion exchange on the electrode, simple hydrated ions and more complex ions generated after the addition of complexing or chelating agents. There are significant differences in dispersion ability, electroplating speed, crystal structure and characteristics of the coating. If the shape of the part is not particularly complex and the coating can meet the requirements, it is advisable to choose a simpler plating solution formula as much as possible. This not only has low cost, is easy to control and manage, but more importantly, sewage is also easier to treat.

For a practical electroplating solution, the following items must be carefully considered.
