The advantages of electrostatic spraying are more

Spraying machine brings a lot of convenience to our work. It is very important to know how to use this equipment correctly. Let us find out what problems should be noticed!

    1. According to the size of the work object, the gun heads with different calibers can be used. Generally speaking, the spray head with a diameter of 5~6 mm can be sprayed in a small area, and the nozzle head with a diameter of 6 mm or more can be used for a large area. The type of paint is different, and its specific gravity is also different. If the ratio is large, the wind pressure can be increased, but the wind pressure must not exceed the strength of the electromagnetic field. The electrostatic generator can be used not only for painting, but also for high-frequency spark testers to solve construction problems such as plastic linings, as well as for spraying cement and spraying plastics.

    2. When performing electrostatic spraying, it should also be noted that the distance between the suspended workpiece and the ground must be more than 1 meter, and the distance between the workpiece and the workpiece does not collide with each other, and the smaller the distance, the better. The rotation of the spray gun is also very important. Generally, the cyclone spray gun speed is 800 rpm, and the rotary cup spray gun speed must be greater than 1000 rpm. If the two guns are not working in the same plane, they can be closer together.

    3. In addition, because the DC voltage used for electrostatic spraying is as high as 100,000 volts, accidents will occur if there is a slight inadvertentness. Therefore, it is necessary to pay attention to operational safety.

    Experts say that in order to improve the efficiency of electrostatic spraying, two or more spray guns are often used simultaneously for spraying. At this time, the paint mists with the same electric charge mutually repel each other and affect the quality of the coating film. Therefore, the distance between the two spray guns is at least 1 meter.
