CONVENTIONAL APPLICATION SYSTEM AND THEIR DRAWBACKS
Oiling has been conventionally made by contact system (brushes, rollers, pads) or spraying system (airspray or airless spray).
Contact systems are always affected by the uneven flatness of the surface which causes uneven film thickness or dry stripes.
Spraying systems are always associated with a more or less pronounced overspray which impairs the deposition rate, polluting in the same time the working site.
Moreover the oil deposited by conventional means is free flowing from the sites of coils severely contaminating storage floors.
In both cases oil consumption is well over the theoretical - often even three or four times as much and the uniformity of the coating obtained is very poor.
ELECTROSTATIC APPLICATION PRINCIPLES
We shortly remember the principles of electrostatics for the readers which are not familiar with this type of application.
Electrical charges of the same name repel each other, electrical charges of opposite name attract each other.
Moreover fluid filaments or drops immersed in a strong electric field undergo the electrostatic pressure and break out in ever smaller electrically charged droplets which repel each other creating a finely atomized fluid mist.
This mist when opposed to an earthed surface is attracted and evenly settles and firmly adheres on this same surface.
In practice the fluid mist is negatively charged and the metal surface is kept at ground potential connecting it to the mass, which is very easily done due to the presence of large metals structures in every process line.
The deposited droplets loose immediately their electric charge so that no evidence of the electrostatic deposition process is left on the coated surface.
The function of the ELETTROSPRAY oilers is purely based on our deep knowledge of the electrostatic principle.
As a result a minumum of DOS coating film weight is less up to
*0mg/m2 per side.
