18 Electrostatic Removal Equipment (Ionizer) Electrostatic removal equipment generate ions by corona discharge to eliminate (neutralize) static electricity. An ionizer is useful under the following conditions:
Grounding is not possible.
Workpiece comprises insulated materials such as rubber.
Humidity levels cannot be controlled.
Conductive materials cannot be applied. Electrostatic removal equipment generate positive or negative ions by utilizing corona discharge etc. Ions sent to the workpiece adjust the ion balance of positively or negatively charged workpieces, making them electrically balanced and eliminating static electricity. Electrostatic removal equipment generate ions. Corona discharge Details Basic mechanism of electrostatic removal using ions (Ion balance) Ionizer Workpiece An ionizer generates ions by applying high voltage to an electrode needle. When a positive voltage is applied, positive ions are generated. When negative voltage is applied, negative ions are generated. q Positive charging w Making up for a deficiency of electrons e Completion of electrostatic removal Molecules return to the atmosphere Negatively ionized molecule Eliminates static electricity by providing ions to a charged workpiece.
