What must be done after anodizing of industrial aluminum profiles

Update time : 2022-09-19 20:47:19

Industrial aluminum profiles are usually not put into use directly after being produced through various processes. In order to improve the corrosion resistance and surface hardness of industrial aluminum profiles, anodizing treatment is generally required. Anodizing treatment is to energize both ends of the aluminum profile as two poles, and form a dense artificial oxide film on the surface of the aluminum profile through electrolysis. This oxide film is transparent and hard, which can greatly improve the service life of industrial aluminum profiles.

However, after the anodization is finished, some treatment is required to achieve the icing on the cake.

1. Hot water rinse:

The purpose of hot water rinsing is to age the film. However, the water temperature and rinsing time must be well controlled. Too high water temperature or too long time will also cause the oxide film to become thinner. If there is a colored oxide film, it will also cause the color to fade. The water temperature should be controlled at 40-50 degrees celsius, and the time should be controlled between 30-60 seconds.

2. Drying:

The industrial aluminum profiles that have been washed with hot water are hung obliquely on the shelf so that water can flow out of the cavity naturally. The glossiness of the oxide film of the aluminum profiles that have been dried naturally is not affected and is more natural.

3. Aging:

The aging method can be determined according to the climatic conditions. In summer, it can be exposed to sunlight, and aluminum oxide can be baked in an oven in rainy days or in winter. The process conditions are: the temperature is 40~50℃, and the time is 10~15 minutes.
