How to Remove Salt Corrosion from Aluminum
Aluminum have the advantages of high specific strength, corrosion resistance, and economical processing, making them one of the most widely used metal materials today. Although the oxide layer on the surface of aluminum alloy can prevent further oxidation of the metal within the layer, the corrosion problem will still produce many limitations on the application of aluminum alloy. Let me introduce today about the way to remove aluminum corrosion.
1. Cleaning and surface treatment.
First, you need to remove corrosion products and dirt from the aluminum surface. You can use cleaner or soapy water (no strong acid or alkali type cleaners). Or use a soft sponge for wiping. If the corrosion is deeper, you can use sandpaper or sanding machine to remove the corrosion layer.
2. Coating Protection
After cleaning and repairing the corrosion, you need to protect the surface of the aluminum. This is because the surface will corrode again after some time if it is not coated. We can use paints, varnishes, organic coatings, etc. to protect the aluminum.
3. Polishing
After corrosion, the aluminum may be corroded so that the surface protection layer will lose its effect. Therefore, we can choose to use polishing machines to re-polish the surface. This can make the aluminum surface to regain the gloss and remove the corrosion material. It is important to note that after polishing, the aluminum needs to be coated with a protective agent, so that the aluminum can be protected from corrosion for a long time.
4. Replacement of aluminum
Severe corrosion of aluminum can not be repaired by physical and chemical agents. Therefore, the aluminum should be replaced in time after judging the serious corrosion. Avoid it to cause unnecessary safety impact, through the detection of corrosion area and depth we can know whether the aluminum needs to be replaced. In our daily life, we should stay away from the serious corrosion of aluminum buildings, because it will have safety hazards.
Conclusion
Methods of removing aluminum corrosion include: cleaning and surface treatment, replacing the aluminum, polishing and coating. While these methods can lead to the repair of corroded aluminum, consumers need to be more careful to buy aluminum after surface treatment. This will enable you to avoid the problem of aluminum corrosion.
