Corona Charging Method-How It Works
In corona charging, a high voltage potential is developed at an electrode located in or near the powder stream. With most corona guns this occurs as the powder exits the gun. (See diagram #l.) An ion field is generated between the electrode and the grounded product. Powder particles passing through this field are bombarded with ions, become charged, and are attracted to the grounded product. The charged powder particles accumulate on the grounded product and are electrostatically retained long enoughRead More …
