With the development of modern industry, aluminum and its alloys are more and more widely used in aviation, automotive, electronics and other industries. However, due to the chemical characteristics of the oxide film and high activity on the surface of aluminum, the electroless nickel plating process commonly used in the industry faces the problem of poor plating bonding when treating aluminum. In order to solve this problem, Bigely Technology has developed an environmentally friendly zinc sinking water BC-22, which effectively improves the bonding strength of the electroless nickel plating layer on aluminum.
Aluminum surface treatment processes usually include zinc dipping and a secondary activation step to improve the surface condition for the adhesion of subsequent plating layers. Some researchers have further pointed out that the quality of the zinc immersion layer directly determines the bonding effect of the subsequent nickel plating. In the conventional zinc immersion process with cyanide, although the bonding of the plated layer is improved, the treatment of the waste liquid is complicated and more harmful to the environment.
In contrast, Bigely environmentally friendly zinc sinking water BC-22 does not contain cyanide, simplifying the process of waste solution disposal. In addition, BC-22 is easy to build and maintain, does not contaminate the bath, and does not shorten the bath life. These features make it environmentally friendly and safe, while ensuring ease of operation.
Importantly, the formation of a homogeneous and dense zinc layer on the surface of the aluminum treated with BC-22 substantially improves the bonding of the plating during the electroless nickel plating process. The optimization of the pre-treatment process is crucial for the densification and bonding of the layer, and BC-22 has a clear advantage in this respect, as it effectively avoids failures such as skinning during the subsequent nickel plating process by generating a dense zinc layer, and improves the quality of the layer.
To sum up, Bigely environmentally friendly zinc sinking water BC-22 not only provides good plating bonding, but also has multiple advantages such as cyanide-free process, simple treatment, environmental protection, etc. It provides a suitable pretreatment solution for the electroless nickel plating process of aluminum, which can help to improve the quality of plating layer on the surface of aluminum.
