Problems needing attention in the safe use of electrostatic plastic spraying equipment

Electrostatic spraying equipment is a common equipment of coating equipment. It brings a lot of convenience to our work. However, any mechanical operation has certain potential hazards. Even the best coating equipment electrostatic spraying machine operator may be negligent. Therefore, the relevant knowledge of how to correctly use this equipment is very important, Now let's find out what problems we should pay attention to!

1. Firstly, gun heads with different sizes and calibres can be used according to the size of the work object. Generally speaking, gun heads with a diameter of 5 ~ 6 mm can be used for spraying small areas, and gun heads with a diameter of more than 6 mm can be used for spraying large areas. Due to different types of paint, its specific gravity is also different. If the ratio is significant, the wind pressure can be increased, but the wind pressure must not exceed the strength of electromagnetic field. The electrostatic generator can not only be used to spray paint, but also replace the high-frequency spark tester to solve the construction problems such as plastic lining, but also can be used to spray cement and plastic.

2. During electrostatic spraying, it should also be noted that the distance between the suspended workpiece and the ground must be more than 1m, and the distance between the workpiece and the workpiece should be as small as possible on the premise of no collision with each other. The rotation 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. If two spray guns are not working on the same plane, they can be close to each other.

3. In addition, because the DC voltage of electrostatic plastic spraying equipment is as high as 100000 volts, accidents will occur if you are careless. Therefore, you must pay attention to operation safety. Operators must wear electrified shoes (leather soled shoes are electrified). Before operating the safety measures of electrostatic spraying machine of coating equipment, it is necessary to fully clean the sole of shoes. At the same time, the conductive objects in the coating room of electrostatic spraying machine of coating equipment must be grounded.

The above are the matters needing attention when operating machinery of electrostatic automatic spraying equipment. In order to improve the efficiency of electrostatic spraying, two or more spray guns are often used at the same time. At this time, the paint mist with the same charge repels each other and affects the film quality. Therefore, the distance between the two spray guns should be 1m.
