Powder spraying is the use of corona discharge phenomenon make powder coating adsorption on the
workpiece. Powder spraying gun powder spraying its process is: connect the cathode, workpiece
grounding (positive), Powder for powder by system by compressed air gas into the spray gun, the
gun front with high voltage electrostatic generator to produce high voltage, corona discharge ,
near the charge, powder by the gun nozzle jet, constitute a loop to form coating of charged
particles, it is the role of the electrostatic force, sucked With opposite polarity artifacts,
along with the increase in the number of powder spray, is, the more charge accumulation, when
reaches a certain thickness, due to electrostatic repulsion Role, will not continue to
adsorption, so that the whole artifacts to obtain a certain thickness of powder coating, and
then after heat to make powder melt, flow ping, curing, namely In the hard coating surface
formation.

Powder spraying is indispensable in modern high-speed multi-color offset printing craft
process. Its main role is to prevent the print on the back of the sticky dirty, improve
printing quality and efficiency Powder using pure natural plant as raw materials, refined by
modern science and printing powder spraying is an indispensable tool in offset printing! Its
main role is prevention Check back in the process of printing of printed matters sticky dirty
speed up the drying process.
