ELECTROSTATIC COATER AND ELECTROSTATIC COATING METHOD |
摘要 |
A charge remaining in an electrostatic coater when power supply to the electrostatic coater is stopped is neutralized at an early stage. A rotary atomizing head 102 receives a high voltage of negative polarity from a cascade 104. An electrostatic coater 100 further includes a second high-voltage generator 110 that generates a high voltage of positive polarity. The second high-voltage generator 110 is composed of a Cockcroft-Walton circuit. The Cockcroft-Walton circuit is composed of diodes and capacitors. A high voltage of the electrostatic coater 100 is controlled by a controller 10. Immediately after running of the electrostatic coater 100 is stopped by stopping power supply to the cascade 104, power is supplied to the second high-voltage generator 110. The high voltage of positive polarity generated by the second high-voltage generator 110 is supplied to the rotary atomizing head 102 for a predetermined time period. |
