The anodizing process has been an indispensable processing part for aluminum plates in many fields. 5005 Anodized aluminum sheet has a higher abrasion resistance, corrosion resistance, light resistance and weather resistance. It can be also colored with different colors, making its application value greatly improved.
The aluminum sheet is the main structural materials for doors, windows and curtain walls today. Without surface treatment, the aluminum plate has a single appearance and is easily corroded in a humid atmosphere, making it difficult to meet the high decorative and weather-resistant requirements of building materials.
In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, the aluminum plate is generally subjected to surface treatment.
The temperature has a significant effect on the performance of the anodic oxide film. If the temperature is too high, the wear resistance and corrosion resistance of the oxide film are reduced, and film formation is difficult; if it is too low, the transparency of the film is reduced, the coloring performance is poor, the brittleness is enhanced, and it is easy to crack.
In the electrolytic coloring production process of anodized aluminum sheet, if we want to achieve uniform coloring and keep the color difference within a certain range to reduce the occurrence of coloring defects, we need to pay attention to the control of the anodizing process.
In addition, the workers should find the cause of poor dying effect in time and properly resolve to ensure product quality. Haomei Aluminum, as a big anodized aluminum sheet suppliers, always deal with the coloring defect in time to ensure it meet the requirements of customers.
