Surface anodizing is a material protection technology that uses anodizing equipment to form an oxide film on the surface of metallic materials. The workpiece is immersed in an electrolyte solution, and an external anode current is applied for this process. After metallic materials or finished products undergo surface anodizing treatment, their corrosion resistance, hardness, wear resistance, electrical insulation and heat resistance are substantially improved. Aluminum is the metal most frequently subjected to anodizing treatment.
The anodizing treatment of aluminum and aluminum alloys refers to the process where aluminum or aluminum alloy workpieces act as the anode. They are placed in an electrolyte solution and energized. Electrolysis forms a thin aluminum oxide film on their surfaces.
Performance Characteristics of Anodizing Equipment
1.High Production Capacity: For the anodizing of aluminum or aluminum alloys, continuous operation is available from workpiece pre-treatment to the anodizing stage.
2.Excellent Weather Resistance: During anodizing, the thickness and density of the oxide film are determined based on different application requirements of products. For instance, anodized aluminum panels keep stable performance indoors over long-term use without discoloration, corrosion, oxidation or rust. Anodized aluminum products with a film thickness greater than 10 μm are suitable for outdoor use and will not discolor under long-term sunlight exposure.
3.Distinct Metallic Texture: Anodized aluminum plates have high surface hardness, good scratch resistance and attractive appearance. They retain the natural metallic luster of aluminum products (color modification available), highlighting a modern metallic aesthetic and raising product grade and added value.
4.High Fire Resistance: These are pure metal products with no paint or chemical substances on the surface. They do not burn at 600°C and release no toxic gases, meeting fire safety and environmental protection requirements.
5.Strong Stain Resistance: Fingerprints are hardly left on the surface. It is easy to clean and free of corrosive spots.
