Advantage of Oxidation Stage Anodic Film

In our building with aluminum windows and doors, curtain walls, the thickness of the level of the general requirements is anodized aluminum grade AA10, AA15 level, however, in some areas due to the relatively harsh climate, AA10 and AA15 grade level anodic oxide film can not be guarantee aluminum doors and windows, walls of life, and therefore, the film thickness of the anodized film directed AA25 grade level development trend. Exterior envelope of modern architecture tends uses AA25 grade anodized aluminum film or decorative plates trend.

 

AA25 grade anodized film has the following advantages:

 

1. Good corrosion resistance

 

Due to the impact of industrial pollution, and the environmental impact of bad weather, exacerbated aluminum windows and doors, curtain wall anodic oxide film on the corrosion, shortening the aluminum doors and windows, walls of life. The AA25 grade anodized film when the film is high, good corrosion resistance, suitable for use in harsh environments.

 

2. Good acid resistance

 

Due to environmental pollution reasons, in many places it will appear under the acid rain phenomenon, leading to aluminum windows and doors, curtain wall surface treatment film discoloration, loss of light and other defects, thereby reducing the aluminum doors and windows, walls of life. The AA25 grade anodized film has good acid resistance, can withstand acid rain, erosion, and ensure the aluminum doors and windows, walls of life.

 

3. High oxidation film surface hardness, wear resistance

 

AA25 grade anodized film formed on the surface of the aluminum oxide film thick and dense, increase the aluminum surface hardness, good abrasion resistance, can withstand wind and sand erosion over many years to live, and as aluminum doors and windows, walls of regular maintenance wash time.
