Aluminum is widely used in various fields due to its excellent corrosion resistance and lightweight characteristics. However, when plating aluminum workpieces, we often need to do zinc deposition treatment first, and the quality of the zinc layer in this process directly affects the performance of the final product. Sometimes we may encounter problems of rough zinc layer, spots and uneven color, these faults not only affect the appearance of the product, but also may affect its corrosion resistance. So, how to solve these problems?
First of all, we need to understand the reasons for these problems. The oxide film and impurities on the aluminum surface itself are the main factors affecting the quality of the zinc deposition layer. Traditional acidic and alkaline cleaning methods can remove some of the contaminants, but they cannot clean the oxide layer on the surface of the aluminum, so that the zinc layer is prone to roughness and spots in the subsequent zinc deposition process.
Secondly, improper control of process parameters is also an important reason for the poor quality of the zinc layer. In particular, the control of time and temperature both directly affect the uniformity and denseness of the zinc layer. If not operated properly, both can lead to rough zinc layer and uneven deposition.
In response to these problems, the BC-22 zinc sinking water developed by Bigely Technology provides us with an effective solution. Bigely BC-22 zinc sinking water is characterized by a wide range of control of operating parameters and easy maintenance of the bath, which is especially suitable for products with high surface quality requirements. After using BC-22 zinc water, the zinc layer is uniform, thin and dense, which can effectively reduce the failure rate in production.
In conclusion, the problems of rough zinc layer, speckles and uneven color in aluminum electroplating zinc sinking process mainly come from improper treatment of aluminum surface and improper control of process parameters. By using Bigely BC-22 zinc sinking water and optimizing the process, we can effectively improve the quality of the zinc layer and meet the performance requirements of the plated products.
