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.

Industrial aluminum profile manufacturers can not stretch aluminum profiles until they are cooled to below 50 degrees.

I believe everyone is familiar with this product of industrial aluminum profile! Industrial aluminum profile is a kind of material that many enterprises often use in the production and processing process. The reason why industrial aluminum profile is favored in many enterprises is not only because of its beautiful appearance, but also because of its excellent electrical conductivity. On the basis of the same weight, the electrical conductivity of industrial aluminum profile is twice that of copper material! But this is under the condition that the processing technology of industrial aluminum profiles is good, especially the stretching technology of industrial aluminum profiles should be done well.

1. The aluminum alloy profile must be cooled to below 50℃ before it can be moved to the stretching frame for stretching operation. If the temperature is too high, stretching will not only burn the human body and the tops, but also present twists and turns, twisting, dysfunction and other waste products before and after aging because it cannot eliminate the internal stress of the aluminum alloy profile. The brand aluminum of aluminum profile is highly recyclable, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.

2. The stretching amount is controlled at about 1%, and it should be noted that if the stretching amount is too high, there will be head-to-tail scale errors, water-like twist (fish scale) marks on the surface, low elongation, high hardness and brittleness (low plasticity). Too low stretching will make the compressive strength and hardness of the profile low, and even aging (quenching can not improve the hardness, and the profile is easy to bend (commonly known as broadsword bending).

3. In order to control the tensile deformation and well control the dimensional change of the whole profile, appropriate special clamps and appropriate methods should be selected. The brand aluminum of aluminum profile is highly recyclable, and the characteristics of recycled aluminum are almost the same as those of primary aluminum. Especially for opening material, circular arc material, cantilever material and zigzag profile, we should pay more attention to the reasonable and useful use of tensile clamping pad.

4. Pay attention to the stress conditions of feet, thin teeth, long legs, circular surfaces, inclined surfaces, openings, viewpoints, etc. of profiles with high width-to-thickness ratio, long overhanging walls, large radians, different wall thicknesses, and strange shapes, so as to avoid the defects such as deformation, twisting, and spiral of some or point-like dimensions of profiles.

5. Because the tops have the effect of preventing heat from emitting, the aluminum profiles with high requirements for decoration accessories must be turned up and down, back and forth, so as to facilitate uniform heat dissipation and reduce the transverse bright spots caused by uneven heat dissipation and different crystallinity, especially for aluminum profiles with large width and thick walls.

6. Do not touch, pull, stack, jam or entangle with each other during picking, moving and stretching, and keep a certain interval between them. The brand aluminum of aluminum profile is highly recyclable, and the characteristics of recycled aluminum are almost the same as those of primary aluminum. The aluminum alloy profiles with easy twists and turns and long discharge length should be disposed of in time, and they should be maintained and disposed of when necessary.
