Appication of the powder paint
– For paint placement, a coating gun in electrostatic field, a powdering/recovering cabinet, a reticulation furnace are necessary
– It is the most used method ;it is based on the partial powder covering by a high voltage performed by the gun cascade
– This method is based on the particle charging by friction to get the same effect as Corona gun, but without generating an electrostatic field.
– The powder particles are charged here by pushing them towards a surface specailly shaped for this purpose
– It is used especially for the parts with a geometrical complex surface (deep spaces)
‘Fluidized bed’ method
– This method is based on the direct immersion of the warmed parts in the fluidized bed and it is used only for specialized industries.
