Aluminum alloy materials because of their unique advantages make the material has a wide range of applications, which is mainly due to the strong plasticity of aluminum materials, high temperature resistance and other characteristics. At the same time, aluminum surface treatment technology such aluminium edge trim as aluminum oxidation processing technology has been further developed, which has further expanded the application range of aluminum alloys.
At present, the market demand for coloring using aluminum oxidation processing is increasing. Relevant experts pointed out that in this process, there are many places that are worth noting: First, when using aluminum oxidation processing technology to color, you need to pay attention to time, which is mainly because the length of the coloring time not only affects the quality of coloring, but also has a great impact on color resistance. Improper handling will cause abnormal color.
Second, in the process of coloring, the voltage must be controlled, and the level of the voltage will have a great impact on the color speed and color changes.
Third, thorough oil removal work must be carried out before coloring, otherwise obvious spots will appear in the film layer. In addition, it is very aluminum tile trim important that the temperature of the coloring must be appropriate, otherwise the color film will fog.
The coloring of alumina products can make the aluminum alloy cloaked in a colorful coat, which has played an excellent decorative effect. According to the method classification, it can be divided into spontaneous coloring, adsorption coloring, and electrolytic coloring. Most of the decolorization problems occur aluminum tile edge trim in adsorption coloring. Since the dye is adsorbed on the surface of the aluminum oxide film pores, decolorization is inevitable. However, if the hole can be sealed, the decolorization of the aluminum oxide film can be eliminated. Among the many sealing processes, the simplest is hot water sealing, which is low cost but poor effect. Steam sealing is very expensive, and its sealing effect is the most obvious.
