Problems and effects of anodizing on industrial aluminum profiles

Update time : 2023-04-04 18:36:00

What is the role of industrial aluminum profiles anodizing?

1. The membrane produced by anodic oxidation has several microns to dozens of microns, and is solid and wear-resistant; The membrane generated by conductive oxidation is only 0.01-0.15 micron, the wear resistance is not very good, but it can conduct electricity and resist atmospheric corrosion, which is its advantage.

2. Oxide film is originally non-conductive, but because the film generated by conductive oxidation is very thin, it is conductive, suitable for some applications in the need of conductive scenes.

With what method can solve the problem that the service life of industrial aluminum profiles is not long after anodizing?

In order to solve the problem that industrial aluminum profiles achieve higher corrosion resistance and wear resistance, industrial aluminum profiles should be anodized after extrusion production. The anodizing of industrial aluminum profiles is to form a hard oxide film on the surface of aluminum profiles soaked in acid and alkali solution through artificial electrification. After the oxide film is formed, some treatment is needed to achieve a more stable effect.

1. Rinse with warm water

Warm water cleaning can make the newly generated film aging, but the cleaning time should not be too long. If the water temperature is too high or the washing time is too long, the oxide film will become thinner. Oxidized tint treatment for light surface color.

2. Air dry

Warm water washing aluminum profile hanging Angle tilt 30 degrees, the residual water in the industrial aluminum profiles smooth outflow, natural dry aluminum profile oxide film gloss more natural. You can also use a blower to help dry, improve efficiency.

3. Aging treatment

Aging is the process of aging the oxide film on the surface of aluminum profiles at high temperatures. Anodized aluminum profiles can be exposed to sunlight in the summer and baked in the oven in the winter or rainy season. The temperature should not be too high (40-50℃), the time should not be too long. Limit it to 10-15 minutes.

After these three steps of treatment, industrial aluminum profiles anodized film more stable, longer life.
