Precautions for use of the electrostatic powder coating line

The electrostatic powder coating line, as one of the most common types of coating equipment, brings a lot of convenience to our work, but any mechanical operation has certain potential dangers. The relevant knowledge is very important, let us understand what should be noted below!

1, first of all, according to the size of the work object can use the different caliber of the large and small gun head. Generally speaking, spray a small area can be used 5 ~ 6 mm caliber gun head if a large area can be used with more than a 6 mm caliber gun head. As the type of paint is different, its specific gravity is also different, if the specific gravity can be increased air pressure, but the wind pressure must not exceed the strength of the electromagnetic field. Electrostatic generators can not only be used to spray paint but also to replace high-frequency spark testers, to solve construction problems such as plastic lining, can also be used to spray cement and spray plastic, etc. work.

2, when electrostatic spraying, should also pay attention to the distance between the hanging workpiece and the ground must be more than 1 m, and the distance between the workpiece and the workpiece on the premise of mutual non-collision, the smaller the distance the better. The rotational speed of the gun is also important, generally 800 rpm for a cyclone gun and more than 1000 rpm for a cyclone cup gun. If two spray guns are not working on the same plane, they can be closer together.

 3. Also, since the DC voltage used in the electrostatic powder coating line is up to 100,000 volts, accidents can occur if you are not careful, so you must pay attention to operational safety. Operators are required to wear electrically energized shoes (leather-soled shoes are electrically energized). The soles of the shoes need to be thoroughly cleaned before operating the electrostatic coating machine safety measures of the coating equipment. At the same time, electrically conductive objects in the booths of electrostatic paint sprayers on painting equipment must be securely grounded.

 These are the things that need to be taken into account when operating machinery for electrostatic automatic spraying equipment. Experts say that to improve the efficiency of electrostatic spraying, two or more guns are often used at the same time for spraying. At this time, the paint mist with the same charge repels each other and affects the quality of the coating film, so the distance between the two guns is at least 1 meter. It is important to remember that safety comes first and operation comes second. No matter what kind of operator you are, please be aware that careful handling of electrostatic sprayers for coating equipment is a prerequisite for preventing some hazards.
