Properly increasing the powder coating thickness can effectively reduce the formation of particles, the coating should not be too thick, generally too thick affect the size of the coated workpiece, impact, flexibility, adhesion and other performance decline, the general coating thickness control in 60-80um is normal.
For powder spraying industry, the thickness of the coating can be controlled by the following methods:
A: the number and arrangement of the spray guns in the powder coating booth.
B: the amount of powder and air pressure (powder, atomization, fluidization parameter) of the powder coating gun.
C: the speed of conveyor chain, that is, powder coating conveyor chain speed;
D: the way and arrangement of the coated workpiece.
