Analyze what causes industrial aluminum profiles to turn black.

Industrial aluminum profile is an alloy material with aluminum as the main component. Aluminum materials with different cross-sectional shapes can be obtained by hot melting and extrusion of aluminum bars. However, the mechanical properties and application fields of industrial aluminum profiles are different with different proportions of added alloys.

In the current house construction, industrial aluminum profiles are indispensable. Industrial aluminum profiles can be used for all aluminum profiles except those used for building doors and windows, curtain walls, indoor and outdoor decoration and building structures.

After oxidation, the appearance of industrial aluminum profile is very beautiful. When assembled into products, aluminum profile fittings are used, which is more environmentally friendly and convenient to install, disassemble, carry and move. It is widely used in automatic machinery and equipment, sealing frame, assembly line conveyor belt, elevator, glue dispenser, testing equipment and so on.

The following aluminum profile manufacturers have summarized several reasons for easy blackening:

1, external factors, because aluminum is an active metal, under certain humidity and temperature conditions, it is easy to be oxidized to black or moldy.

2. Because the cleaning agent is highly corrosive, if it is used improperly, it will cause corrosion and oxidation to aluminum profiles.

3. Improper treatment of aluminum alloy materials after cleaning or pressure inspection creates conditions for mildew and accelerates the generation of mildew.

4. Many manufacturers do not do any cleaning after the processing procedure, or the cleaning is not thorough, which will leave some corrosive substances on the surface, which will accelerate the mildew of aluminum profiles.

5, warehouse storage height is different, also can cause oxidation mildew phenomenon.

What is the processing technology of industrial aluminum profiles?

Industrial aluminum profile is an alloy material with aluminum as the main component. Aluminum bars can be obtained with different cross-sectional shapes by hot melting and extrusion. However, the mechanical properties and application fields of industrial aluminum profiles are different with different proportions of added alloys.

What is the processing technology of industrial aluminum profiles in the following small series?

1. The preliminary process of deep processing of industrial aluminum profiles includes rolling, extrusion, stretching, forging and other steps. In these steps, aluminum rods are extruded into industrial aluminum profiles with different sections.

2. Extruded industrial aluminum profiles need cutting, stretch bending, stamping, surface treatment and other processes. These processes can form an oxide film on the surface of industrial aluminum profiles, which can improve the chemical and mechanical properties of industrial aluminum profiles.

3. After surface treatment, the industrial aluminum profile needs a series of precision machining by CNC or special machine tools, welding and other equipment.

4. After all the above steps are completed, an anodized industrial aluminum profile with a length of 6m/piece can generally be obtained. At this time, the industrial aluminum profile can be further processed according to the user's own needs. Such as customized length, corner cutting, punching and tapping, assembling equipment aluminum profile frame hood, etc.

5. The principle of deep processing of industrial aluminum profiles is: the more accurate the better. The saw blade in deep processing needs to be grinded, and after cutting, the aluminium scrap generated during processing needs to be cleaned.
