[0002] During the processing of aluminum alloy flanges, lubricants such as engine oil, hydraulic oil, and cooling oil may be produced, and these oil stains may adhere to the surface of the aluminum alloy. In addition, stains such as gold chips may also be produced during the processing. If these oil stains and stains are not cleaned in time, they will affect the subsequent treatment or processing technology and remain on the surface of the aluminum alloy. The purpose of cleaning is to remove the oil stains and stains remaining on the surface of the aluminum alloy during the processing so that the aluminum alloy can be further processed or treated. After cleaning, the surface of the aluminum alloy is smooth and clean, and can be better treated or processed by spraying, electroplating, oxidation and other treatments or processing.

[0003] There are many ways to clean aluminum alloy flanges. The specific method needs to be considered comprehensively based on the pollutants on the aluminum alloy surface, processing technology, equipment and other aspects. The following are some commonly used cleaning methods:

[0005] 2. Alkaline cleaning: Add alkaline substances to clean water, soak the aluminum alloy for several minutes, and then rinse it with clean water. It is suitable for the situation where there is a lot of oil on the surface of the aluminum alloy.

[0006] 3. Pickling: Add acidic substances to clean water, soak the aluminum alloy for several minutes, and then rinse it with clean water. It is suitable for rust and oxidation on the surface of aluminum alloy.

[0007] 4. Chemical cleaning: Use a specific cleaning agent to clean the grease, paint, coating, etc. on the surface of the aluminum alloy. It is suitable for situations where the surface pollutants are serious and difficult to clean.
