Abstract
Disclosed is an ultrasonic spray coating system comprising an ultrasonic spray head with integrated fluid delivery system (IFDS), which consists of an ultrasonic transducer with a spray forming tip, an ultrasonic generator, an external liquid applicator, a precision liquid delivery system and air directors. The coating liquid is delivered to the spray forming tip on the ultrasonic transducer from an external liquid applicator. The liquid is stored in a pressurized reservoir and fed to the liquid applicator by a precision liquid delivery system. The ultrasonic vibrations of the spray forming tip break up the liquid into small droplets and propel them from the tip in the form of a spray. The spray produced with ultrasonic energy alone is a very narrow 'sheet-like' pattern. The width of the spray pattern produced is equal to the width of the spray forming tip (2 mm to 4 mm). Air directors are used to produce air streams to further shape and accelerate the ultrasonically produced spray. Air directors can be used to produce three distinct spray patterns, based upon the nature and placement of the air stream—narrow mode spray pattern; wide mode spray pattern; or side mode spray pattern.
