METHOD OF ELECTROSTATICALLY COATING WITH HIGHLY CONDUCTIVE MATERIALS

摘要

Work is electrostatically coated with highly conductive materials by air or hydrostatic atomizing spray guns. The rate of material application to work for water base material such as porcelain enamel is high being in excess of 3 mils of film thickness in less than 60 seconds to prevent "dry spray." The problem of "dry spray" is further controlled by placing the spray guns very close to the work (less than 12 inches).
