摘要:
An electrostatic atomizing device includes a discharge section capable of retaining a liquid, a voltage applying section for applying a voltage to the discharge section, and a control section for setting the voltage applied by the voltage applying section to a given voltage at which a charged particulate water can be produced in an amount equal to or greater than a given amount. The control section is configured to set the voltage applied by the voltage applying section to a voltage lower than the given voltage at an operation start, and then to change the lower voltage to the given voltage. The electrostatic atomizing device can shorten a time needed before the electrostatic atomizing phenomenon occurs.

A control unit (146) determines an atomization state of an atomization electrode (135) and controls a voltage application unit (202) and a heating unit (154) according to the determination, thereby controlling dew point - atomization electrode temperature at a value suitable for atomization.

A method of stripping, prepping and coating a surface comprises first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging coating particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to thereby coat the surface. The particles form both mechanical and electronic bonds with the surface.

摘要:
An electrostatic coating apparatus (1) includes: a spray gun (2) configured to spray a coating material onto a coating object (CD); a voltage application device (4) configured to apply a high voltage to the spray gun (2); and a current measurement device (5) configured to measure electric current flowing through the spray gun (2). When the spray gun (2), which is in a state of not spraying the coating material onto the coating object (CD) and is under application of the high voltage from the voltage application device (4), is located at a distance from the coating object (CD), the electric current flowing through the spray gun (2) is measured by the current measurement device (5). A grounded state of the coating object (CD) is checked, based on the measured electric current. This shortens the time required for checking the grounded state, while allowing for downsizing and simplified configuration of production equipment and reduction of equipment cost.
