Brief introduction 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.
Main Advantage
Due to the special process flow and a 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 heavy cleaning and the exhaust air volume can also be reduced by nearly 30%. half. Moreover, the electrostatic coating process is very green and environmentally friendly, and will not cause pollution to workers and affect their health. It is an excellent coating method.

Our country’s status quo
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 this type of coating. Moreover, the technical level of workers in our country needs to be improved, and the spraying 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 coating technologies are all attached to the background of high-tech, and generally go deeper into the finer level of matter, rather than the kind of drastic spraying. The spraying at the ionic level is usually more fine and uniform, ensuring the quality of the coating. However, these two types of coating equipment and processes have only achieved one of the three points at best, and the requirement of "green environmental protection" is still not up to standard. So we should still continue to explore.
