The charging characteristic of a powder is directly related to both the physical properties of the material itself and the specific processing conditions.
Factors affecting
charge include:
- Composition
- Particle size
- Substrate type (conductivity)
- Substrate size
- Line speed (time to spray)
- Humidity
- Virgin to reclaim ratio
- Gun flow rates (vol. and speed)
- Gun voltage and current (amount of charge)
- Resin type
- Particle shape
- Substrate shape (flat, frame, recess, etc.)
- Substrate temperature
- Booth airflow
- Gun to substrate distance
- Quality of ground
- Gun tip and deflectors
It is important to examine and find the best process factors
to improve your bottom line, reduce
overall costs, and meet performance requirements with quality and efficiency.
