Washing goldsmith’s grout cutter taps is the most vivid problem in preparation for subsequent electrodeposition, galvanization, varnishing, PVD or vacuum vacuuming.
The action of ultrasounds in an aqueous detergent reaches the innermost parts, just where the paste is thickened, literally exploding the fat that is seized and esterified in the detergent body.
Even the abrasives, released from the fat that held them glued to the surface of the pieces, are removed from the piece and plummet to the bottom of the bathtub.
IN WASHING OREFICERIA POWDER SUPERIORITY TAPWARE OF WATER DETERGENT RESPONSIBLE TO ORGANIC SOLVENTS
Especially for washing orifice faucet utensils, the use of an aqueous detergent is much more efficient and economical and preferable 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 washing plants there is continuous cycle distillation with enormous energy consumption problems.
But even more serious environmental pollution problems.
Not to mention disposal issues.
Also at the end of solvent washing, typical dusts on the surface of the treated part are the inorganic abrasives (alumina, corundum, etc.).
Because they are inorganic, they are not dissolved in the solvent and are present on the surface of the part, requiring subsequent manual removal (tamping).
