Rotary atomizing electrostatic coating apparatus

摘要

A rotary atomizing electrostatic coating apparatus includes a plurality of shaping air nozzles (6) for expelling shaping air having a pressure of about 80 - 250 kPa at an exit of each shaping air nozzle (6) and having an amount of air to be expelled per nozzle of about 10 - 20 Nl/min. Each shaping air nozzle has a diameter of about 0.6 - 1.5 mm. The number of shaping air nozzles (6) is determined so that a summation of diameters of all shaping air nozzles (6) is equal to between about 1/6 - 1/4 times an entire circumferential length of a portion having a greatest outside diameter of the atomizing head (1).
