Abstract
A painting target surface of a resin bumper is painted by discharging a paint mist from a spray gun toward the painting target surface with a charged conductor arranged in contact with an opposite side to the painting target surface. The paint mist is uncharged or is charged with electric charges having an opposite polarity to that of the conductor and at a potential having a lower absolute value than that of the conductor.
Claims17
A painting method for an insulator, the painting method comprising painting a painting target surface of the insulator by discharging, toward the painting target surface of the insulator with a charged conductor arranged in contact with or proximity to an opposite side to the painting target surface of the insulator, a paint mist that is uncharged or is charged with electric charges having an opposite polarity to a polarity of electric charges of the conductor and at a potential having a lower absolute value than an absolute value of a potential of the conductor.
A painting apparatus for an insulator, the painting apparatus comprising:
- a conductor configured to come into contact with or proximity to a surface opposite to a painting target surface of the insulator;
- a charging unit configured to charge the conductor;
- and
- a discharge apparatus configured to discharge, toward the painting target surface of the insulator, a paint mist that is uncharged or is charged with electric charges having an opposite polarity to a polarity of electric charges of the conductor and at a potential having a lower absolute value than an absolute value of a potential of the conductor.
