How does the corrosion resistance of aluminum profile come?
December 08, 2020
Good extruded aluminum profiles, the surface corrosion resistance is not strong, must be anodic oxidation surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum, in the aluminum profile oxidation process is also a certain amount of detailed flow, the oxidation steps are mainly:

1, Surface pretreatment;Chemical or physical methods are used to clean the surface of the profile, exposing the pure matrix, in order to obtain a complete, compact artificial oxide film.Mirror or matte (matte) surfaces can also be mechanically obtained.

2, Anodic oxidation;After surface pretreatment, under certain technological conditions, the surface of the matrix is anodized to form a compact, porous, strong adsorption AL203 film.

3, the hole sealing;The pores and pores of the porous oxide film formed by anodic oxidation are closed to enhance the anti-pollution, anti-corrosion and anti-wear properties of the oxide film.The oxide film is colorless and transparent. The strong adsorbability of the oxide film before sealing the hole can be used to adsorb and deposit some metal salts in the hole, which can make the profile appearance show many colors other than the natural color (silver white), such as;Black, bronze, gold and stainless steel, etc.

Industrial aluminum is a kind of widely used metal building materials products, because of its superior soft texture and easy processing performance, as well as its surface noble metal quality, etc., deeply loved by people.Therefore, only by controlling every detail in the production process of aluminum profile, can the quality of aluminum profile be guaranteed.

In fujian, the double constant group, product variety, quality oubiao industrial aluminum and flexible and convenient for fitting, in mechanical manufacturing, factory equipment, industrial production line, factory automation and automated production equipment, and other fields, to bring our customers such as: exhibition frame structure, equipment, machinery casings, machine frame protection device, protective barrier, safety fence, industrial assembly line, aluminum workbench , etc.
