1.3. OPERATING PRINCIPLE OF POWDER SPRAY GUN
(refer to Fig.3)
The SRV 028-Twin 60° spray gun operates on the "corona" effect principle. An ionizing electrode [A] located at the end
of the spray gun and is connected to a high negative potential. Air is ionized by the electrode which is surrounded by the
intense electric field.
The emitted ions follow the magnetic field pattern and reach the part being painted. Powder is charged when it passes
through the ionized electric field.
In order to ensure that the powder sticks to the part being painted, the latter must be a good conductor (or semi-conductor)
and properly earthed (the electrical resistance of the part, in relation to the earth must be less than 1 M
Ω
).
The high voltage generator is integral with the spray gun.
