Electrostatic spraying has been widely used since the development in the 1950s. It combines the advantages of various spraying processes into a new spraying method. When a DC high voltage is applied between the grounded workpiece and the spray gun, an electrostatic field is generated.
Spraying machine brings a lot of convenience to our work. It is very important to know how to use this equipment correctly. Let us find out what problems should be noticed! 1. According to the size of the work object, the gun heads with different calibers can be used. Generally speaking, the spra
(1) high quality cold rolled sheet with thickness less than 1mmNo pinholes will appear after painting. If there is a crack, because there is air in the crack, coating solidification may cause coating interruption and discontinuity, that is, large pores;A porosity is caused by rust or dirt on the sur
The reason for the pinhole in the spray is related to the following points:1. The workpiece has a small amount of water or oil on the surface before spraying. When the temperature is solidified, the oil or water evaporates and vaporizes, leaving pinholes on the workpiece.2. If the pinholes are one p
1. Complete solve the problem of workpiece powder grooves on the dead angle, groove with powder.
2. Ensure that products without off color, don't fall off.
3. Ensure no powder spillover, fast color change.
