What special treatments do the aluminum plates of RT open stacking aluminum boxes need to undergo to improve their durability?

The special treatment process that the aluminum plates of RT open stacking aluminum boxes undergo plays a vital role in making them stand out from many similar products. Anodizing is an electrochemical process that applies voltage to make the aluminum plate an anode, and an oxidation reaction occurs in a specific electrolyte, thereby generating a layer of aluminum oxide film with uniform thickness and dense structure on the surface of the aluminum plate. This film not only has high hardness and good wear resistance, but also has good insulation and corrosion resistance.
The anodized film can effectively block the intrusion of external corrosive substances (such as water, acid, alkali, etc.) and protect the aluminum plate substrate from erosion. At the same time, its hardness and wear resistance also greatly improve the impact and scratch resistance of the aluminum box during transportation and stacking. By adjusting the oxidation conditions and subsequent coloring treatment, the surface of the aluminum box can be given rich colors and gloss, enhancing the visual appeal of the product.
Coating treatment includes but is not limited to powder spraying, electrophoretic paint, fluorocarbon paint, etc. These coating materials have good adhesion and weather resistance, and can maintain the beauty and integrity of the aluminum box surface for a long time. High-quality coatings can form a protective barrier that effectively resists the erosion of harsh environments such as ultraviolet rays, moisture, and salt spray, while reducing wear caused by friction and extending the service life of the aluminum box. The coating treatment provides a wide range of color options, allowing RT open stacking aluminum boxes to meet the specific color and appearance requirements of different industries and customers.
Chemical oxidation is usually used as a pretreatment step for coating treatment. Through a slight oxidation reaction, a thin oxide film is formed on the surface of the aluminum plate to improve the adhesion between the coating and the aluminum plate. Compared with anodizing, chemical oxidation is cheaper and suitable for occasions where corrosion resistance is not particularly high, but it can still provide a certain degree of protection.
Plastic powder is electrostatically sprayed onto the surface of the aluminum plate and then cured at high temperature to form a strong and durable coating. This treatment not only enhances the durability of the aluminum box, but also provides a rich selection of colors and textures. Although not as commonly used as anodizing and coating treatments, in certain cases, electroplating or chemical plating can provide an additional protective layer, such as zinc plating, nickel plating, etc., to enhance the rust resistance and decorative effect of the aluminum box.
