<strong>1.</strong>3. Deposits, sintering on spraying devices (deflector plates, nozzles)<br />
Detection Possible causes Remedy<br />
Mechanically damaged or worn parts<br />
Powder in circulation too fine<br />
Metered addition of new powder to<br />
circulation insufficient<br />
Humidity in powder coating material<br />
too high<br />
Feed air pressure too high<br />
Pressure fluctuations in compressed<br />
air system<br />
Clean injectors, deflector plates<br />
and nozzles such that surfaces are<br />
nei<strong>the</strong>r roughened nor get<br />
damaged<br />
Continually meter and add new<br />
powder automatically<br />
Check function of refrigeration<br />
dryer and oil-water separators<br />
Reduce feed air pressure<br />
