Aluminum oxidation dyeing process is one of the surface treatment methods for aluminum profiles, which is a new type of gold imitation process of oxidation by dyeing. Aluminum alloy material has a wide range of application fields because of its unique advantages, which is mainly due to the characteristics of aluminum material such as strong plasticity and high temperature resistance. At the same time, aluminum surface treatment technology such as hard oxidation coloring processing technology has been further developed, making the application range of aluminum alloy further expanded.

  Aluminum hard oxidation within a certain limit, the current density rises, the film growth rate rises, the oxidation time shortens, the generated film has more pores, easy to color, and the hardness and wear resistance rise; the current density is too high, it will make the surface of the parts overheat and the local solution temperature rise due to the influence of Joule heat, the dissolution speed of the film rises, and there is a possibility of burning the parts; the current density is too low, the film growth rate is slow, but the generated film is denser and the hardness and wear resistance is reduced.

  In aluminum anodize processing, in the industrial processing, we are also using such a principle to carry out certain technical attacks, in some of the main aluminum surface treatment, we are using some new treatment and processing methods. 21st century is the century of environmental protection, environmental issues are becoming increasingly important, resources and energy more tight, the construction of a circular economy, take the road of sustainable development has become the focus of global attention and The urgent task, and become the development of all walks of life and human activities guidelines.
