Regarding galvanizing, new technologies such as hot-dip galvanizing and alloy galvanizing can significantly improve the adhesion and corrosion resistance of the zinc coating. Hot-dip galvanizing involves immersing the metal mesh in molten zinc, which firmly adheres to the surface and forms a dense protective film. Alloy galvanizing involves adding other alloying elements, such as aluminum and magnesium, to the zinc solution to further enhance the corrosion and oxidation resistance of the zinc coating. In the marine engineering field, hot-dip galvanized and alloy-galvanized metal mesh is widely used in offshore platform protective fencing, piers, and other facilities, effectively resisting corrosion from seawater and wind, extending the service life of the facilities.
The powder coating process improves the uniformity and durability of the coating by improving the powder coating formula and spraying technology. The new powder coating has improved adhesion, wear resistance, and weather resistance, forming a strong and beautiful coating on the surface of the metal mesh. In outdoor furniture and landscaping, powder-coated metal mesh, with its rich colors and excellent weather resistance, adds aesthetic value and practical value. For example, park benches and flower bed fences are made of powder-coated metal mesh, which not only looks beautiful but also withstands the test of sun and rain, maintaining good performance for long-term use.
Passivation treatment enhances the quality of the passivation film on the metal mesh surface by optimizing the composition of the treatment solution and the treatment process, improving its corrosion resistance. In the protection of electronic equipment and precision instruments, passivated metal mesh effectively prevents oxidation and corrosion on the metal surface, protecting internal components from environmental influences. For example, within a computer chassis, passivated metal mesh serves as an electromagnetic shield, effectively shielding against electromagnetic interference and preventing rust, thereby ensuring the normal operation and lifespan of the computer.
