Sheet metal chassis and cabinets are widely used in various fields. Sheet metal chassis and cabinets are made of metal materials and used in a wide range of fields. Because of the metal properties of sheet metal chassis and cabinets, they are also widely used outdoors. The first challenge for outdoor use is the harsh outdoor environment. Therefore, the manufacturer has strict requirements for sheet metal chassis and cabinets.
For the sheet metal chassis and cabinets used outdoors, the workmanship is required to be fine, and the metal materials are also selected in terms of materials. Because good performance can have strong corrosion resistance, customers should understand the materials when selecting sheet metal chassis and cabinets. The sheet metal chassis cabinet also needs to be treated with electrostatic plastic spraying, which can strengthen the external corrosion resistance, reduce the water absorption and air permeability, and have excellent mechanical properties, especially the performance.
The harsh environmental conditions during storage, transportation and use shall be considered for the paint coating of sheet metal chassis and cabinet. In addition to good mechanical properties, the paint coating shall also have good water resistance, chemical corrosion resistance, light resistance and mold resistance.
The chassis and cabinet are processed and produced with metal materials. In the process of metal materials, attention should be paid to the metal thickness, which should be higher than the thickness of formed products after processing. However, since metal materials are mass produced by manufacturers, it is inevitable to encounter oxidized materials. What should we do with such materials
Some materials are treated by cutting boards, binding edges, welding or manual fire baking and heating, resulting in black oxide scale. This kind of oxide skin is relatively strong. In the past, people usually used nitric acid and hydrofluoric acid for strong corrosion to remove it. However, this method does great harm, especially to people's body and surrounding environment. Its corrosivity is also large and its cost is high. Now it has been eliminated by sheet metal processing.
There are different treatment methods for oxidation on the surface of chassis and cabinet. One is sand blasting, which uses the method of spraying micro glass beads to remove the black oxide skin on the surface. Another method is to soak and wash the pickling passivation paste and the cleaning solution with inorganic additives at room temperature.
If a layer of black oxide is always attached to the surface of the chassis and cabinet, it is easy to leave a bad impression on the customer. In order to avoid this situation, there should be a good solution in dealing with oxidation. At this stage, the development of China's hardware industry is not standardized, and there is no core development direction. The scale of most hardware industries is relatively small, and the products produced are relatively low-end. In such a competitive social environment, the development of hardware industry is relatively humble and difficult. In order to get good development, we should rely on the professional processing technology of sheet metal processing to continuously improve the use value of products.
For sheet metal processing industry, its development is still immature, and there are many places to be improved. Continuously strengthen and innovation to improve the service performance of processed products. In addition, we should often learn from some well-known researchers and train them to promote the continuous progress of their own processing technology. Only by first raising the processing technology can we produce high-quality products and get the recognition of consumers. In addition, if the sheet metal processing industry wants to be bigger and stronger, it should also start its own response and create its own. If you want to be known by many people, it is very important to do a good job of publicity. With the help of advertising platforms such as the Internet and newspapers, we have been constantly launched. In addition, we should also realize the diversification of business methods. We can not only set up physical stores such as hardware stores and flagship stores, but also sell online to continuously expand the business scope.
