Metal products are prone to react with oxygen and water in the air, leading to the formation of rust on the metal surface. Rust not only damages the appearance of metals, but also further accelerates the corrosion process of metals. To prevent this situation, spraying paint on metal surfaces is an effective protective measure. Spray painting can form a protective film on the metal surface, which can effectively isolate the metal from contact with air and water, thereby slowing down the oxidation process of the metal and achieving the purpose of rust prevention
In addition, spray painting not only protects the metal, but also enhances its aesthetic appeal. By painting, the color and appearance of metal can be changed according to design requirements, making it more beautiful.
The types of spray painting include electrostatic powder spraying and traditional paint spraying. The former disperses powdered coating into powder mist particles and adsorbs them on the metal surface through high-voltage electrostatic action, while the latter disperses liquid coating into paint mist particles and adheres them to the metal surface through compressed air. Both methods can form a uniform and solid coating on the metal surface, providing good protection and decorative effects.
