Oxidation treatment is a particularly important part of industrial aluminum processing procedures. In the oxidation process, the details are slightly missed, but the result is far away. This is also the reason why many aluminum profile companies have stricter recruitment requirements. After communicating with several experienced people in the industry, I summarized the points that should be paid attention to after the oxidation treatment of industrial aluminum materials: (1) Especially important hot water washing. For the process of hot water washing, the temperature and time of the hot water must be strictly controlled. If the water temperature is too high or too low, the film will be thinned and the gloss will be dim. The same problem occurs in the time of the same
industrial aluminum profile. The unwritten standard time in the industry is 40℃~50℃, and the time is 0.5~1MIN. (2) After the hot water is rinsed, it is of course dry. There are many ways to dry, generally air-drying is used, which is the most natural and effective. The color of the film layer processed according to the drying method is not affected, and is the most natural. (3 Aging. After following the first two steps, the next step is aging. Same as drying, the natural aging effect is the best, but it depends on the weather. It can be placed in the sun under the sun to accelerate the aging. Process; it can be baked in an oven on cloudy or rainy days. Generally, the temperature of the oven is kept between 40℃~50℃, and the time is 10~15min. (4) Rework. Unqualified industrial aluminum materials should be dried and aged It is selected before the process, because the film formed in these two processes is more difficult to retreat, which consumes extra manpower and material resources. A better way is to place the unqualified industrial aluminum material that jumps out for aluminum anodizing. On the fixture, anodize aluminum in a sulfuric acid solution for 2 to 3 minutes. After the film is soft and fall off, it can be re-conducted anodizing after being cleaned with lye and nitric acid is emitted. 'Strictly follow the above steps' If the details are implemented in the post-oxidation process of industrial aluminum, high-quality industrial aluminum profile can be manufactured.————The article comes from the Internet.
