Advantages of powder spray guns
We talk more about the benefits of powder coating, but little about what a powder gun does. So, as one of the components of the powder spraying equipment in the electrostatic powder spraying equipment factory, what are the salient features of the powder spray gun? Today, there are two main types of powder spray guns: friction guns and high pressure guns. Friction guns have their own characteristics due to different charging methods and electric fields from high-voltage guns. They also have their own unique advantages in the electrostatic spraying process. The details are as follows:
1. Safety: The spraying equipment has no high-voltage electrostatic generator. The stimulation of high-voltage electric shock will always make people nervous, and there is no metal electrode in the friction gun, so there will be no spark discharge caused by the short circuit of the electrode during the spraying process to ignite the gas-powder mixture.
2. Convenience: It is very convenient to spray with a friction gun. First, the friction gun is not connected to the high-voltage line, so it is easy to hold; secondly, it is less affected by the spraying distance. The friction gun is getting closer and closer to the workpiece, and the spraying effect is similar.
3. High efficiency: There is no metal electrode in the friction gun, and there will be no electrode powder accumulation phenomenon, so as to avoid the powder accumulation on the electrode from falling off, and to ensure that the surface of the powder layer is smooth and smooth. Using the friction gun, the friction gun can spray thicker coated wires, spray small workpieces or workpieces with complex surface shapes, which is much better than the high pressure gun.
4. Power saving: The electrification of the friction gun powder is caused by the friction between the powder and the gun wall, which determines that the friction gun does not need a high-voltage power supply-electrostatic generator in electrostatic spraying. Thus saving 10-30% of equipment investment, especially for small test equipment, the saving rate is higher.
To do your job well, you first have to sharpen your tools. For the powder coating process, good powder coating equipment is the basis and premise. From small spray guns to large powder spray booths, only by continuous research and development, innovation and improvement of equipment can we produce spray products that meet customer needs in a more efficient, convenient, safe and environmentally friendly way, and can convince and trust customers.
