3 Types of Reasons for Surface Pollution of Patterned Aluminum Plates

Caused by improper use

Improper use can cause pollution to the surface of aluminum plates, especially when patterned aluminum plates are contaminated with alkaline solutions during use, which may cause corrosion to the surface and leave a thin layer of alkaline film, which will affect the visual appearance. To address such pollution, we do not need to worry too much, just use a mild alkaline cleaning agent combined with warm water for cleaning.

Contaminated by acidic substances

Regardless of whether it is alkaline or acidic substances, once they reach a certain concentration, they will cause damage to the surface of patterned aluminum plates. For such pollution sources, we can use brush cleaning to effectively clean them. Generally, residues can be washed with flowing circulating water. For special residues, tools and chemicals need to be used for cleaning.

Long term exposure to air

If patterned aluminum plates are exposed to air for a long time, especially in humid environments, it is easy to cause surface corrosion of patterned aluminum plates. In response to this situation, ordinary patterned aluminum plates need to undergo corrosion resistance treatment on the surface. High quality corrosion-resistant aluminum plates generally form a natural oxide film on the surface of the aluminum plate, and the presence of this film can help us prevent deeper oxidation corrosion. When cleaning, you can choose to brush the surface stains of the board first, and then repeatedly rinse with clean water. The patterned aluminum plate can be washed cleaner using the above methods.
