The manufacturer of Twin Screw Extruders for Powder Coatings tells you that electrostatic equipment brings a lot of convenience to our work. It is very important to know how to use this equipment correctly. Let us understand the problems that should be noticed What are there!

1. Depending on the size of the work object, gun heads with different sizes and calibers can be used. Generally speaking, gun heads with a caliber of 5 to 6 mm can be used for spraying small areas, and gun heads with a caliber of 6 mm or more can be used for large areas. Different types of paint have different specific gravity. If the specific gravity is large, the wind pressure can be increased, but the wind pressure must not exceed the strength of the electromagnetic field. The manufacturer of Twin Screw Extruders for Powder Coatings tells you that electrostatic generators can not only be used for painting, but also replace high-frequency spark detectors to solve construction problems such as plastic linings, and can also be used for spraying cement and plastics.
2. When carrying out 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 must be as small as possible on the premise of not colliding with each other. The rotation speed of the spray gun is also very important. Generally, the rotation speed of the cyclone spray gun is 800 rpm, while the rotation speed of the rotary cup spray gun must be greater than 1000 rpm. The manufacturer of Twin Screw Extruders for Powder Coatings tells you that if the two spray guns are not working on the same plane, the distance between them can be closer.
3. In addition, because the DC voltage used by electrostatic spraying equipment is as high as 100,000 volts, accidents may occur if you are not careful. Therefore, you must pay attention to operating safety.
The manufacturer of Twin Screw Extruders for Powder Coatings tells you that in order to improve the efficiency of electrostatic equipment, two or more spray guns are often used for spraying at the same time. At this time, because the paint mist with the same charge repels each other and affects the quality of the coating film, the distance between the two spray guns should be at least 1 meter.
