1. Mechanical refurbishment method:
After long-term use, the surface of aluminum plates may show phenomena such as oxidation and corrosion, and they need to be refurbished. Mechanical refurbishment can be adopted. Professional polishing machines are used to grind the surface of the aluminum plate to remove the surface oxide layer, dirt and corrosion products, restoring the original luster of the aluminum plate.
2. Chemical refurbishment method
Apart from mechanical refurbishment, chemical refurbishment is also a commonly used method. By using specific chemical agents, such as special cleaning agents for aluminum products, stains and oxide layers on the surface of aluminum plates can be removed. After cleaning, the surface of the aluminum plate will become smoother. Then, necessary protective treatments are carried out to enhance the corrosion resistance and oxidation resistance of the aluminum plate.
3. Repainting or coating:
Refurbished aluminum plates can be repainted or coated as required. First, ensure that the surface of the aluminum plate is clean, dry and free of oil stains. Then, follow the correct painting technique and select the appropriate coating for spraying. This not only repairs the aluminum plate but also changes its color, enhancing its aesthetic appeal.
