1. Anodizing technology: Enhance corrosion resistance and wear resistance
Anodizing is an important process in the surface treatment of die-cast aluminum alloys. It can not only improve the appearance of the material, but also greatly enhance its corrosion resistance and wear resistance. Through anodizing, a dense oxide film will be formed on the surface of the aluminum alloy. This film has a strong resistance to moisture, salt, acid and alkali substances, thereby effectively preventing corrosion and oxidation on the surface of the aluminum alloy.
In addition, anodizing can also increase the hardness of the aluminum alloy surface, making it more wear-resistant. When rubbed by external substances such as wind, sand and dust, the surface of the aluminum alloy will not be easily damaged, thereby extending the service life of the lamp. In a high-speed working environment, the surface-treated aluminum alloy can withstand greater pressure and impact, ensuring the long-term and stable operation of lighting equipment.
2. Spraying technology: Improve oxidation resistance and UV resistance
In addition to anodizing, spraying technology is also an effective way to improve the durability of Die Cast Aluminum Alloy Lighting Parts. During the spraying process, a special spray coating is evenly sprayed onto the surface of the aluminum alloy to form a protective layer. This protective film can effectively prevent the external environment from damaging the aluminum alloy. The choice of spray coating can be customized according to the use environment of the lamp. Usually, coatings with strong antioxidant and UV resistance are selected to meet the use requirements of outdoor lighting equipment in high temperature, strong light and other environments.
The sprayed surface can not only enhance the corrosion resistance of the aluminum alloy, but also effectively resist ultraviolet radiation, avoiding fading or aging of the material surface due to long-term sunlight. In some high temperature and strong ultraviolet environments, the protective effect of the spray coating is particularly important. It can effectively reduce the damage to the appearance of the lamp and maintain the beauty and performance of the lamp.
3. Powder coating technology: Enhance weather resistance and scratch resistance
Powder coating technology is another common surface treatment method, especially suitable for lighting equipment that requires strong weather resistance and scratch resistance. Under the coating of powder coating, a layer of coating with strong adhesion is formed on the surface of the aluminum alloy, which can effectively improve the lamp's resistance to wind and sand, UV and chemical corrosion.
Powder coating technology can not only improve the corrosion resistance of aluminum alloy surface, but also effectively enhance its scratch resistance. In particular, during long-term use, lamps may rub against the surrounding environment, and the surface is prone to scratches or other physical damage. The coating of powder coating has strong scratch resistance, which can effectively protect the surface of the lamp and ensure its stability and appearance durability in harsh environments.
4. Surface treatment improves the heat dissipation performance of lamps
Die-cast aluminum alloy itself has good thermal conductivity, which can efficiently dissipate the heat generated by LED lighting fixtures to avoid damage to LED chips due to overheating. The heat dissipation effect of aluminum alloy after surface treatment is more significant. Surface treatment processes such as anodizing, spraying and powder coating can not only enhance the corrosion resistance of aluminum alloy, but also improve its heat dissipation performance.
5. Anti-ultraviolet ability: prolong the service life of lamps
Outdoor lighting equipment is often exposed to direct sunlight. Long-term exposure to ultraviolet rays can easily cause the appearance of lamps to age and fade, and even affect their functions. By adopting surface treatment technologies such as anodizing, spraying and powder coating, the anti-ultraviolet ability of aluminum alloy has been greatly improved. The damage of ultraviolet rays to the aluminum alloy surface can be effectively blocked, preventing the aging of the surface coating, thereby ensuring that the appearance of the lamp remains as good as new after long-term use, while improving the durability and stability of the lamp.
