How To Get The Corrosion Resistance Of Industrial Aluminum Profiles?
Dec 05, 2017

Extruded industrial aluminum, its surface corrosion resistance is not strong, the surface treatment through anodic oxidation to increase the corrosion resistance of aluminum, wear resistance and appearance of the aesthetic, in the industrial aluminum oxidation process is also a certain detail flow, the main oxidation steps are:

1, Surface pretreatment: Using chemical or physical methods to clean the surface of the profile, exposing the pure matrix, in order to facilitate the acquisition of complete, dense artificial oxide film, but also through mechanical means to obtain a mirror or matte (Matt) surface

2, Anodic oxidation: surface pretreatment of the profile, in a certain process conditions, the substrate surface anodic oxidation, a layer of dense, porous, strong adsorption of AL203 film layer.

3, Sealing hole: The anodic oxidation of the porous membrane produced by the pore sealing pores, so that the oxidation film anti-pollution, corrosion and wear-resistant performance enhanced. The oxide film is colorless and transparent, using the strong adsorption of the oxidized film before sealing, and depositing some metal salts in the membrane pores, which can make the appearance of the Profiles (silvery white) Many colors, such as: black, bronze, gold and stainless steel color, etc.

Industrial aluminum is a wide range of applications of metal building materials products, because of its advantages of soft texture and easy processing performance, as well as the surface of the noble metal texture and so on, deeply loved by people. Therefore, only the control of industrial aluminum production process in every detail, in order to ensure the quality of industrial aluminum products.
