How to clean aluminum products?

With the development of machinery manufacturing industries such as aviation, automobile industry, and electronics, aluminum alloy metal processing has become very common, but in the manufacturing process of aluminum products, it is inevitable that cutting oil and stamping oil will remain on the surface. If the oil removal is not clean, the subsequent processing work will be difficult to carry out.
Generally speaking, the pollutants that need to be removed from the surface of aluminum alloy products include various oil stains, residual polishing paste, handprints, oil seals, surface waxes, etc.
The main methods for cleaning the surface of aluminum alloy are solvent degreasing, chemical degreasing, electrochemical degreasing, etc.

Solvent degreasing is mainly to dissolve the dirt on the surface of aluminum alloy by using aluminum alloy cleaning agent. Generally speaking, water-based cleaning agent is the main method. The solvent has a strong dissolving effect on saponified oil and non-saponified oil. It can remove the residual polishing paste on the surface of the workpiece.

The cleaning methods of aluminum alloy cleaning agents mainly include scrubbing, dipping, spraying, ultrasonic cleaning, etc. Among them, the ultrasonic cleaning method has the characteristics of high efficiency and high cleaning rate, and is suitable for large-scale cleaning, especially for some workpieces with complex shapes, fine holes and blind holes. It is a very practical aluminum alloy workpiece cleaning at present.
