(1) Brief description of electrostatic coating equipment: Electrostatic atomization has developed for more than half a century since the beginning of the last century. With the progress of science, its own equipment has been continuously innovated, becoming more and more advanced and perfect. Today, electrostatic coating has become the fastest and most common coating method in industrial coating technology. Electrostatic coating equipment is generally equipped with electric spray guns, high-voltage DC electrostatic generators, coating machines and control systems.

(2) Main advantages: Due to the special technological process and high degree of computer control of electrostatic coating, it is widely used in a variety of mixed-flow coating, and in terms of appearance, it is obviously better than manual spraying. In addition, energy saving is its brightest advantage. Usually, the spray booth using electrostatic painting will save about 30% of the space. Due to its own cleanliness, it also reduces the heavy cleaning. The exhaust air volume can also be reduced by nearly half, and the electrostatic coating process is very green and environmentally friendly, and will not pollute the workers and affect their health. It is an excellent coating method.

(3) Current situation in my country: In fact, the electrostatic coating method has been successfully developed in my country for a long time, but the tools have always been lagging behind in Europe and the United States, resulting in more reliance on imports of consumables for such coatings, and the level of workmanship in my country needs to be improved. The spray quality is usually not ideal.

Therefore, in order to use this coating method on a large scale, researchers should be encouraged to continuously develop suitable advanced coating equipment and supply more high-quality workers. To sum up, it is not difficult to see that these excellent The Chuzhuang technology is all attached to the background of high-tech, and generally goes deeper into the material

Small level, not the kind of drastic spraying, this kind of spraying at the ion level is usually more delicate and uniform, ensuring the quality of the coating, but the two types of coating equipment and processes are currently at best. One of the points, and the requirement of "green environmental protection" is still not up to standard. So we should still continue to explore.
