Industrial aluminum profile is used by many industries because of its series of properties. Industrial aluminum profile is a kind of alloy material with aluminum as the main component, which is obtained by hot melting and extrusion of aluminum bars with different cross-sectional shapes. After oxidation, the surface of industrial aluminum profile will become very beautiful and easy to clean, which is why major industries choose it! The application fields of industrial aluminum profiles are curtain wall, building doors and windows and some indoor and outdoor decorations, and the types of industrial aluminum profiles applied in these fields are different.

I. Industrial aluminum profiles can be divided into the following categories according to their uses:

1. Aluminum profiles for doors and windows (divided into doors and windows and curtain walls).

2. Special radiator aluminum profile for 2.CPU radiator

3. Aluminum profiles for aluminum alloy shelves are different in cross-sectional shapes, but they are all produced by hot melt extrusion.

Second, according to the alloy classification:

Aluminum profiles can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other brands, of which 6 series are common. The difference between different brands is that the proportion of various metal components is different. Except for commonly used aluminum profiles for doors and windows, such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other building aluminum profiles, industrial aluminum profiles are not clear.

Three, according to the requirements of surface treatment classification:

1. Anodized aluminum

2. Electrophoretic coating of aluminum materials

3. Powder spraying aluminum material

4. Wood grain transfer aluminum

5. Planted aluminum (divided into mechanical planing and chemical polishing, in which chemical polishing is expensive and expensive).

The oxidized aluminum profile is easy to clean even if it is coated with oil.

Aluminum profile is a kind of material often used in many industries now, and it is very good to use it to process various products! Because the industrial aluminum profile itself is very beautiful and generous in appearance, not to mention in quality, it is not only environmentally friendly, but also has a very long service life. However, this is only available after the surface of industrial aluminum profile is oxidized. After oxidation, the surface of industrial aluminum profile is not only resistant to dirt, but also easy to clean even if it is coated with oil. This shows the importance of oxidation treatment of industrial aluminum profiles! So do you know what the oxidation process of industrial aluminum profiles is?

The main process of aluminum profile oxidation is as follows:

(1) Surface pretreatment: the surface of the profile is cleaned by chemical or physical methods to expose the pure matrix, so as to obtain a complete and compact artificial oxide film. Mirror or matt (matt) surface can also be obtained by mechanical means.

(2) Anodizing: Under certain technological conditions, the surface of the profile after surface pretreatment is anodized to form a dense, porous and strong adsorption AL203 film.

(3) Hole sealing: the pores of the porous oxide film generated after anodic oxidation are sealed, so that the anti-pollution, anti-corrosion and wear resistance of the oxide film are enhanced. The oxide film is colorless and transparent. By using the strong adsorption of the oxide film before hole sealing, some metal salts are adsorbed and deposited in the film holes, which can make the appearance of the profile show many colors other than its original color (silvery white), such as black, bronze, golden yellow and stainless steel.
