Anodic oxidation and electroplating of aluminum profiles

Update time : 2022-11-18 18:09:44

1. Anodic oxidation.

Anodic oxidation is a process of aluminum surface treatment, which makes the surface of the product have a layer of chemical conversion film of about 0.5um. This layer of film is golden yellow and placed at the bottom of the coating. It has a strong electrical conductivity and has a wide range of applications in mobile phone batteries and magnetoelectric equipment. This kind of chemical film can be applied to all kinds of aluminum profiles, but it is not wear-resistant, so it also has certain shortcomings. The process requires the grinding layer to be very meticulous, the color is uniform, can not have any bruises, people can not use their hands to touch, can not scratch it.

At the same time, because this product has good wear resistance, it can be widely used in aerospace products and so on. Anodic oxidation process usually has the natural color of wire drawing fog surface, which can be used for polishing and sandblasting, etc. If the surface appears spots, it is due to its poor metal treatment, which needs to be re-heated; If the surface appears rainbow color, it is due to the poor electrical conductivity of the product; If the surface is bruised, it belongs to the problem in the process of transportation, and can be polished again; When white spots appear on the surface of the product, there are oil and other impurities in the water due to the operation.

Two, electroplating process.

Of course, in the modern process, electroplating can solve its shortcomings such as not easy to weld and not wear resistant, and it can be easier to improve its reflection rate, modify its size and so on. At the same time, the electroplating process is not complicated and is widely used in modern aluminum products.

Electroplating process requires the appearance of the product without pinhole burr, etc. In special environment, corresponding changes can be made, but also to prevent power failure in the middle, and in the process of washing, it is necessary to clean all kinds of materials.

How to do a good job of cleaning industrial aluminum profiles?

Jul .17.2023

Spraying cleaning method of industrial aluminum profiles is widely used, because of complex equipment, high process requirements, poor cleaning effect, then how to better do spray cleaning of industrial aluminum profiles?

Aluminum extrusion profile six places are required during the stretching process

Jul .07.2023

The aluminum extrusion profile must be cooled to below 50 degrees before stretching. If the temperature is too high, stretching will not only burn the human body, the hair belt, but also expose absolute waste products such as bending, twisting, and poor performance before and after aging, because the stress in the aluminum alloy profile can not be completely eliminated.

Curtain wall aluminum profile purchase mainly see where?

Jul .06.2023

Appearance quality of curtain wall aluminum profile: the surface of anodic oxide film is not allowed to have electrical burns, oxide film falling off and other defects; Electrophoretic, powder, fluorocarbon profile paint film should be uniform, neat, smooth, do not allow wrinkles, cracks, bubbles, flow signs, inclusions and paint film fall off and other defects, but allow local film within 80 mm at the end of the profile.
