The field of application of electrostatic spraying, which already proved a good result in American enameling shops, has been restricted only for articles of flat shape, such as a range top plate, and the authors, in an attempt to extend this field of application to the domestic wares of more complicated form, made some investigations for the purpose of obtaining some basic data. The general idea based on was that we could use the electrostatic field most efficiently and hence secure the most uniform coating if it could be possible to suspend still the enamel particles in air by compensating the gravity force with the upward current of air produced by the mechanical draught in a spray booth.From the lower end of the spray booth, composed of a vertical cylinder of 180cm long and 50cm in diameter, slip was injected upwards, and the air current in the booth was regulated to be about 100cm per second, which is necessary for keeping the particle at rest at the middle, by exhausting with a fan equipped at the top of the booth. Four square steel pieces having 2cm brim and 10 square cm base were stringed successively along a vertical line at the center of the booth with copper wires of 5cm long. A cylindrical cage of very large mesh composed of thin copper wires and 130cm in length and 30cm diameter, was supported by insulators to serve as a negative electrode, whose nearest distance from samples was about 10cm so that a static voltage of 28 kilo-volt can be applied without sparking over.The authors confirmed that the uniformity of thickness of the coating can be appreciably improved by the existence of electrostatic field, for example, the thickness of the coating at the vertical surfaces increased from 8-17% to 29-102% of the horizontal, only on which the particles may deposit by usual mechanical methods, Further it was confirmed that, by applying the field, the efficiency was increased as much as two times of the usual method.
