Aluminium Construction Profiles Door

In the production process of Industrial aluminum profile, the primary purpose of using chemical or electrochemical polishing is, firstly, to replace mechanical polishing to achieve a smooth and shiny surface on aluminium construction profiles; secondly, it is to perform chemical or electrochemical polishing after mechanical polishing to obtain very high mirror-like reflectivity in aluminum profiles or aluminum components, thus achieving the goal of brightening the surface. After extrusion aluminum profile undergo chemical or electrochemical polishing, although their surfaces can achieve high...

The aluminum extrusion profile used in general engineering applications and aluminium construction profiles can typically enter the anodization production line directly after extrusion. The anodization film obtained exhibits good protective performance in many engineering applications, and the surface basically meets the uniform appearance requirements. If the aluminium profiles are directly subjected to anodization treatment after mechanical polishing, only a smooth anodization film can be obtained, and a highly reflective film layer cannot be achieved. Chemical polishing as a advanced...

It is well known that the fresh surface of aluminum immediately forms a natural oxide film in the atmosphere. Although this oxide film is very thin, it still endows aluminium profile with certain corrosion resistance, making aluminum extrusion profile more corrosion-resistant than steel. With different alloy components and exposure times, the thickness of this film varies, generally within the range of 0.005-0.015um. However, this thickness range is not sufficient to protect aluminium profiles from corrosion. Through proper chemical treatment, the thickness of the anodization film can be...
