Rotary atomizing electrostatic coating apparatus and method

摘要

A rotary atomizing electrostatic coating apparatus includes a plurality of shaping air nozzles for expelling shaping air having a pressure of about 80-250 kPa at an exit of each shaping air nozzle 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 is determined so that a summation of diameters of all shaping air nozzles is equal to between about +E,fra 1/6+EE -+E,fra 1/4+EE times an entire circumferential length of a greatest outside diameter of the atomizing head.
