How does the quality of grounding affect the quality of powder coating?
• The 100 KV discharge at the gun tip creates a corona effect between the gun tip and the object (to be coated). The positive ions are drawn back towards the gun tip. The negative ions search the closest grounded object and are attracted to it immediately. The powder collects the charge on the way to the object and sticks to it. If the grounding is not up to the mark, all the ions will not be attracted to the object and a smaller quantity of powder gets deposited. • Besides this if the grounding is not of good quality it can cause shocks to the operator as well as create sparks. The sparks are very likely to cause fire. It is absolutely necessary to have an efficient grounding. The efficiency meter helps you maintain excellent grounding consistently.
