One of the most important problems in every galvanic treatment is the extreme cleaning of surfaces from greases, oils, dusts, abrasives, all components that would prevent the metal grips from being perfectly adhered to, resulting in slicing.
At the terminal stage, the surfaces of the parts to be treated must be polished almost to the mirror.
This is then done with the plating, that is, the surfaces are brushed with impregnated felt of vegetable or animal fat and abrasives (e.g. corundum, alumina, Tripoli powder, etc.).
Cleansing pastes washing
At the end of this operation on all the pieces, in each grease, the grease is absorbed and hiding with its dusts, which must be completely removed but which is difficult to be eliminated with the only electrolytic degreasing (cathode or anodic).
At this point, the ultrasounds have proved to be the irreplaceable and cheaper solution for the washing of the floating pastes
In the bathroom are installed IMMERSIBLE TRANSMITTERS, which carry the action of the ultrasound directly in close proximity to the details and inexorably remove all that present of dirt and in a short time.
Different types of transducers
I agree with the ultrasound, but for the cleaning of the pasting cake as liquid?
ORGANIC WATERS OR SOLVENTS
Chamfering pastilles washing is the most vivid problem in preparation for subsequent electrodeposition, galvanostegia, varnishing, PVD metallization or under vacuum.
The action of ultrasounds in an aqueous detergent reaches the innermost parts, just where the paste is thicker, by literally exploding the fat that is seized and esterified.
Also the abrasives (alumina, Tripoli powder, corundum, etc.), released from the fat that kept them glued, are removed from the surface of the piece and precipitate on the bottom of the tub.
SUPERIORITY OF WATER DETERGENTS RESPONSIBLE TO ORGANIC SOLVENTS
When washing cake pastes, the use of an aqueous detergent is much more efficient and economical and more preferred than degreasing with organic solvents.
In fact, the solvent dilutes the fat of the batter but does not remove it and as long as the solvent is clean the result may be acceptable, but as the solvent becomes fatigued the result worsens.
In order to maintain an acceptable result, then in the solvent plants a continuous cycle distillation with significant energy consumption problems is carried out.
But even more serious is the problem of environmental pollution.
Not to mention the exhaustion of the spent solvent.
Additionally at the end of solvent washing, typical dusts on the surface of the treated part are no more than inorganic abrasives.
Because they are inorganic, they are not dissolved in the organic solvent and are present on the surface of the part, requiring subsequent manual removal (tamping).
