Fundamentals electrostatic painting electrostatic painting is being painted as a positive electrode, grounded in everyday situations; paint atomizer spray equipment for the negative electrode, then the power of negative pressure, so that the poles would lead to a high voltage electrostatic field. Since the cathode produce a corona discharge spraying plant, you can spray the coating medium charged, and further atomization. In accordance with the role of 'sex repulsion, opposites attract' principle, have been charged coating medium by the electric force (F = twist), the paint was painted to form embracing effect, flows along the power line oriented positively charged coated appearance is, piled into one average, attached to a solid film. Electrostatic painting technique can also be used positive polarity corona discharge, but negative corona discharge threshold voltage lower than the positive polarity corona discharge, and more stable, easy to produce sparks. Under normal scenario will be painted as a positive ground. Electrostatic painting the history of France in 1876 found that static electricity to make liquid particles of action, in 1903 the United States issued a patent by electrostatic atomization, 1944 French Cup has laid the foundation electrostatic spraying. In 1956 the United States is eligible for electrostatic coating apparatus patent, and later the United States, France, Britain, Switzerland, many Japanese companies have been the emergence of various electrostatic painting equipment. 50 years of the introduction of a spinning cup electrostatic spraying equipment, 70 years the introduction of Ω type (ie Park Disc) electrostatic spraying equipment.
