Problems needing attention in the safe use of electrostatic spraying equipment

Electrostatic spraying equipment as a common coating equipment, it brings a lot of convenience for our work, but any mechanical operation has a certain potential danger in which, even the best coating equipment electrostatic spraying machine operators also have negligence, so how to correctly use the relevant knowledge of this equipment is very important, let me know Let's find out what problems we should pay attention to!

1. First of all, according to the size of the work object, gun heads with different diameters can be used. Generally speaking, gun heads with diameters of 5-6 mm can be used for small area spraying, and gun heads with diameters of 6 mm or more can be used for large area spraying. Due to the different types of paint, its proportion is also different. If the proportion is significant, the wind pressure can be increased, but the wind pressure must not exceed the strength of the electromagnetic field. Electrostatic generator can not only be used for painting, but also can replace high-frequency spark detector to solve the construction problems such as plastic lining. It can also be used for spraying cement and plastic.

2. In 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 smaller the distance between the workpiece and the workpiece is, the better. 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 the two spray guns are not working on the same plane, the distance between them can be closer.

3. In addition, as the DC voltage of the electrostatic spraying equipment is as high as 100000 V, accidents will occur if it is not careful. Therefore, attention must be paid to the safety of operation. Operators should wear electrified shoes (leather soled shoes have electrified property). It is necessary to clean the soles before operating the safety measures of electrostatic spraying machine. At the same time, the conductive objects in the coating room of the electrostatic spraying machine of the coating equipment must be grounded.

The above are the matters needing attention when operating the electrostatic automatic spraying equipment. Experts say that in order to improve the efficiency of electrostatic spraying, 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 film quality, the distance between the two spray guns is at least 1m. It needs to be reminded that safety is very important. No matter what kind of operator you are, please know that careful operation of electrostatic spraying machine of coating equipment is the premise to prevent some hazards.
