The surface treatment of the distribution cabinet sheet metal shell is an important step to ensure that the distribution cabinet has a beautiful appearance, corrosion resistance and proper protection. Common distribution cabinet sheet metal shell surface treatment methods mainly include the following:
Spraying treatment:
Spraying treatment is a common method for the surface treatment of the distribution cabinet sheet metal shell. Spraying can be divided into two types: painting and powder spraying. After pretreatment, the paint or powder is sprayed on the surface of the sheet metal workpiece using a spray gun and gas to form a uniform coating. This method can make the sheet metal surface smooth, delicate, not easy to rust, and the color is uniform and beautiful. When spraying, it is necessary to pay attention to the pre-treatment steps, such as removing dust and oil on the surface of the workpiece to ensure the quality of spraying.
Electroplating treatment:
Electroplating is an oxidation-reduction process. By using the metal workpiece as the cathode and the plated metal as the anode, immersing it in an electrolyte with a coating component and passing direct current, a metal coating is formed on the surface of the sheet metal shell. Electroplating includes zinc plating (such as colored zinc, white zinc, blue zinc, black zinc), nickel plating, chrome plating, etc. The electroplating layer can provide good corrosion resistance and decorative properties.
Anodizing:
Anodizing is a surface treatment method that forms an oxide film on the metal surface, which is often used for sheet metal shells of metals such as aluminum alloys. This method can improve the corrosion resistance, wear resistance and hardness of the metal while increasing the aesthetics.
Passivation:
Passivation is the process of forming a protective film on the surface of the sheet metal. The surface oxide layer is usually removed by pickling, and then a dense passivation film is formed to increase the corrosion resistance of the surface.
Other treatment methods:
In addition to the above common surface treatment methods, there are also wire drawing, sandblasting, oxidation and other treatment methods. These methods can be selected according to specific needs and application scenarios to achieve the desired surface effect and performance.
When choosing the surface treatment method for the distribution cabinet sheet metal shell, factors such as the use environment, protection level, appearance requirements and cost of the distribution cabinet need to be considered. Different surface treatment methods have different advantages, disadvantages and applicable scopes, so it is necessary to comprehensively weigh various factors and select the most suitable surface treatment method.
