Abstract
Bei einem Verfahren zur Behandlung von Eisen- oder
Stahloberflächen mit Hilfe fester Strahlmittel setzt man
zwecks Verbesserung des Korrosionsverhaltens und der
Haftung eines ggf. aufgebrachten Lackes mindestens in der
Endphase der Behandlung Strahlmittel ein, die mit einer
Phosphationen und Imin- bzw. Imidverbindung enthaltenden
wäßrigen Lösung versetzt sind.
Besonders geeignete Imin- bzw. Imidverbindungen sind
Aminoguanidin, Auramin, Kreatin, Dicyandiamid, Phthalimid,
Pyrrol, Pyrrolin, Pyrrolidin, Rosindulin und/oder
Triphenylguanidin, vorzugsweise Guanidin.
Gemäß einer besonders vorteilhaften Ausgestaltung versetzt
man das Strahlmittel mit einer durch Zugabe von
Phosphorsäure und Guanidincarbonat im Gewichtsverhältnis
(0,3 bis 3) : l, vorzugsweise (0,5 bis 0,75) : l,
erhaltenen Lösung und stellt die Guanidinzugabe auf 0,2
bis 4,5 g/l, vorzugsweise l,5 bis 2,5 g/l (ber. als
Guanidincarbonat), ein.
