ROTARY ATOMIZING ELECTROSTATIC COATING APPARATUS

摘要

A rotary atomizing electrostatic coating apparatus includes a plurality of shaping air nozzles disposed in a first circle having its center on an axis of rotation of an atomizing head, a plurality of pattern control air nozzles disposed in a second concentric circle having a larger diameter than the first circle. The pattern control air nozzles are located about 3-100 mm behind the shaping air nozzles and inside a circle having a diameter not more than three times a diameter of the atomizing head. An air passage may be formed radially between the shaping air nozzles and the pattern control air nozzles, The advantage is a rotary atomizing electrostatic coating apparatus that virtually eliminates vortices and turbulence in the paint control air flow, so that paint adherence to the coating apparatus is minimized and dripping is eliminated, resulting in a better paint finish.
