In modern home life, small appliances are loved by consumers for their convenience and practicality. In the design of small appliances, stainless steel decorative shells are widely used for their elegant texture and good durability. However, although stainless steel is called "stainless", it may still rust under certain conditions, such as humidity, high temperature or contact with corrosive substances. Therefore, it is particularly important to rust-proof the stainless steel decorative shells of small appliances. This article will explore several advanced technologies for rust prevention of stainless steel decorative shells of small appliances.First of all, coating rust prevention is a common and effective means. By applying a layer of polymer coating or stainless steel rust prevention oil on the surface of the stainless steel decorative shell, a dense protective film can be formed to isolate air and moisture, thereby achieving the purpose of rust prevention. The advantages of this method are simple operation, low cost, and can give the decorative shell rich colors and textures. However, the disadvantage of coating rust prevention is that the maintenance cost is high, and regular inspection and re-coating are required to maintain the rust prevention effect.Secondly, electroplating anti-rust treatment technology is also one of the important means of rust prevention for small household appliances stainless steel decoration shell. Electroplating is the process of plating a layer of other metals or alloys on the metal surface through the principle of electrolysis. Electroplating a layer of metal with better rust resistance, such as chromium, nickel, etc., on the small household appliances stainless steel decoration shell can significantly improve its rust resistance. The electroplating layer is not only beautiful and generous, but also increases the added value of the product. However, the disadvantages of electroplating anti-rust treatment technology are high equipment requirements, high difficulty in operation, and the wastewater and waste gas generated during the electroplating process need to be properly treated to avoid pollution to the environment.In recent years, passivation anti-rust treatment technology has emerged in the rust prevention treatment of small household appliances stainless steel decoration shell. Passivation is to form a dense passivation film on the metal surface through chemical reaction, thereby preventing the metal from directly contacting oxygen and water vapor in the air to achieve the purpose of rust prevention. The advantages of passivation anti-rust treatment technology are simple operation, low cost, and the formed passivation film has good adhesion and corrosion resistance. At the same time, the passivation anti-rust treatment technology can also improve the surface hardness and wear resistance of the stainless steel shell of small household appliances and extend its service life.In addition to the above three anti-rust treatment technologies, there are some other methods that are also widely used in the anti-rust treatment of stainless steel shell of small household appliances. For example, physical polishing technology can remove tiny bumps and depressions on the metal surface to make the surface smoother and flatter, thereby reducing the contact area with corrosive substances and achieving the purpose of rust prevention. In addition, heat treatment technology can also be used to change the internal structure of stainless steel and improve its corrosion resistance.In summary, there are many anti-rust treatment technologies for stainless steel shell of small household appliances, and each technology has its unique advantages and scope of application. In practical applications, the appropriate anti-rust treatment technology should be selected according to the specific use environment and requirements of small household appliances to ensure product quality and user satisfaction.
