    The surface treatment methods of the shelves include anodizing, electrophoretic coating, powder electrostatic spraying, etc., each of which has its own advantages and occupies a considerable market share. The combination of electrostatic spraying racks and thermal insulation bridges makes it more fashionable and makes powder electrostatic spraying racks have more development space, which is irreplaceable by other processing methods.

    The surface treatment methods of the shelves include anodizing, electrophoretic coating, powder electrostatic spraying, etc., each of which has its own advantages and occupies a considerable market share. The combination of electrostatic spraying racks and thermal insulation bridges makes it more fashionable and makes powder electrostatic spraying racks have more development space, which is irreplaceable by other processing methods. Among them, powder electrostatic spraying has the following significant advantages: 1. The process is very simple. Mainly due to the improvement of the automation precision of the main equipment in the production process. The main technical parameters can be controlled by microcomputer, which can effectively reduce the difficulty of process operation and reduce auxiliary equipment. 2. High yield Generally speaking, if the measures are appropriate, the production of substandard products can be controlled to the greatest extent. 3. Energy consumption is significantly reduced In the production process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process. The output current of the rectifier can reach between 8000~11000A, and the voltage is between 15~17.5V. In addition to the heat consumption of the machine itself, it is necessary to continuously use circulating water to cool down, and the power consumption per ton is often around 1000 degrees. At the same time, the reduction of auxiliary facilities can also reduce some power consumption. 4. Reduce water and air pollution Do not use liquid organic solvents such as tablet alkali and sulfuric acid, which can reduce water and air pollution, effectively improve the competitiveness of shelves and plastic steel shelves as environmentally friendly products, thereby reducing some production costs. 5. The labor intensity of workers is greatly reduced. Due to the automatic operation of electrostatic spraying, the feeding method and the use method of the fixture are greatly simplified, the production efficiency is improved, and the labor intensity is reduced. 6. The standard of shelf surface quality requirements has been significantly reduced. Powder electrostatic coating can cover the extrusion line on the shelf surface to the greatest extent, cover up some defects on the shelf surface, and improve the surface quality of shelf products. 7. Compared with other surface treatment films, some physical indicators of the coating have been significantly improved, and the hardness and wear resistance can effectively prolong the service life of the shelf. Powder coating uses powder coatings, and electrostatic spraying is used in this process. Under the action of the accelerated wind, the powder particles generate positive charges when they are ejected from the gun body and come into contact with the negative charge distribution to generate electrostatic adsorption. After curing at high temperature, the adsorption strength of the coating is improved and the coating is prevented from falling off.
