Irregular biting or leakage of aluminum workpieces after micro-etching treatment, as well as the phenomenon of poor bonding after plating, are important problems that plague many plating masters. These problems directly affect the surface quality of the workpiece and plating effect, the reason is mainly due to the surface of the workpiece on the oil and oil film cleaning is not complete.
In the pre-treatment of aluminum alloy plating, the uniformity of the micro-etching process can be seriously hindered if oil or oil film remains on the surface of the workpiece. The cleanliness of the aluminum surface has a decisive influence on the micro-etching effect. Surface contamination can lead to defects in the plating layer. These studies have shown that uneven surface oil contamination and oil film can lead to uneven micro-etching, resulting in subsequent irregular nibbling or leakage of the etching phenomenon, and further affecting the bonding strength after plating.
To overcome this problem, you can use Bigely BC-20 alkaline aluminum micro-etching agent, which uses its own innovative technology with the addition of TBC active ingredient that completely removes oil and grease film from the surface of aluminum workpieces. This ingredient ensures the uniformity of the surface micro-etching and avoids irregular biting and leakage, which in turn improves the bonding of the plating layer.
The uniformity of surface treatment is crucial for the quality of plating layer. And Bigely BC-20 alkaline aluminum micro-etching agent significantly improves the quality of surface treatment of aluminum workpieces by virtue of its good decontamination ability and uniform microetching effect.
Conclusion
The main reason for irregular nibbling or leakage of aluminum workpieces after micro-etching, as well as poor bonding after plating, lies in surface oil and oil film. By virtue of its own innovative technology and TBC active ingredient, Bigely BC-20 alkaline aluminum micro-etching agent is an effective solution to this problem by removing clean surface impurities, ensuring uniform microetching, and improving the bonding of the plated layer.
