The surface of industrial aluminum products can significantly improve the physical or chemical properties of the surface after plating various metals. When the industrial aluminum profile is used as a conductor, the electroplating of silver on the surface can improve the conductivity of the surface or electrical contact parts. To make aluminum easy to weld, its surface is electroplated with copper, nickel or tin; In order to improve its wear resistance, thick electroplating on its surface. In decorative aspects, in fact, most of the electroplating crusher.
The surface electroplating of industrial aluminum profile has been tried and used in actual production for a long time. However, there are oxides between industrial aluminum profiles and coatings, the thermal expansion coefficient of industrial aluminum profiles and metal coatings are different, and the coatings have pinholes and residual electroplating solutions, resulting in poor adhesion of coatings, and long-term use will flake off even immediately after plating. In the field of surface treatment, the electroplating process of industrial aluminum profiles is still in the exploratory stage, and there is no substantial breakthrough for a long time. So far has not formed a perfect, mature technology.
The electroplating quality and the qualified rate of industrial aluminum profile are still the bottleneck of the industry. Conventional industrial aluminum profile electroplating process: industrial aluminum profile electroplating process is composed of three parts: plating pretreatment, electroplating and plating post-processing. Pretreatment of electroplating is the most critical process related to the quality of electroplating products.
