4 Points to pay attention to in the Post-Oxidation Treatment Process of Aluminum Product

YONGU Group

There are many manufacturers of aluminum products in today's era. The most important thing about aluminum products is that they can be oxidized to have a beautiful appearance.

But many manufacturers have encountered many problems after oxidation because they did not pay attention to the following 4 points. Next, our Professional Aluminum Case Company will tell you what to pay attention to after oxidation.

·Rinse with hot water. The purpose of hot water washing is to age the film. However, the water temperature and time should be strictly controlled. If the water temperature is too high, the film layer will be thinned and the color will become lighter.

If the processing time of industrial aluminum profiles is too long, the above-mentioned similar problems will occur. Suitable temperature: 40~50℃， Time: 0.5~1min

·Drying. It is better to dry naturally. The workpieces washed with hot water and highland barley are hung on the shelf obliquely, so that the free water on the working surface flows down in a straight direction.

The water droplets that flow to the lower corners are absorbed with a towel, and the color of the film layer dried by this method will not be affected, and it will appear natural.

·Aging. The aging method of aluminum profiles can be determined according to climatic conditions. In summer, it can be exposed to sunlight, and in rainy days or winter, it can be baked in an oven.

The process conditions are: temperature 40-50 ℃ for 10-15 minutes.

·Repair of unqualified parts. Unqualified conductive oxide film parts should be picked out before the drying and aging process, because the film layer is difficult to remove after drying and aging and will affect the roughness of the workpiece surface.

The author has carried out some explorations in the process of this problem. After a variety of methods, it is found that the following methods are effective and simple, and do not affect the surface quality of the workpiece;

Conclusion:

First, clamp the unqualified workpiece on the fixture for aluminum anodizing;

Then carry out anodic treatment according to the method of anodic oxidation of aluminum in sulfuric acid solution for 2 to 3 minutes. After the film layer is soft and falls off, it can be re-conductive anodic oxidation after a little cleaning with alkaline solution and light emission with nitric acid.

Finally, YONGU case has been cultivating deeply in this industry for 17 years know how to deal aluminum case problem, if you have other similar anodization problems, welcome to contact us. We will answer your question ASAP. Our website:https://yongucase.com/
