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. In a process for the treatment of iron or Steel surfaces are set using solid blasting media in order to improve the corrosion behavior and the Adhesion of any paint applied, at least in the Final phase of treatment with a blasting agent Containing phosphate ions and imine or imide compound aqueous solution are added.

Besonders geeignete Imin- bzw. Imidverbindungen sind Aminoguanidin, Auramin, Kreatin, Dicyandiamid, Phthalimid, Pyrrol, Pyrrolin, Pyrrolidin, Rosindulin und/oder Triphenylguanidin, vorzugsweise Guanidin. Imine or imide compounds are particularly suitable Aminoguanidine, auramine, creatine, dicyandiamide, phthalimide, Pyrrole, pyrroline, pyrrolidine, rosindulin and / or Triphenylguanidine, preferably guanidine.

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. According to a particularly advantageous embodiment the blasting agent with a by adding Phosphoric acid and guanidine carbonate in weight ratio (0.3 to 3): l, preferably (0.5 to 0.75): l, obtained solution and the guanidine addition to 0.2 up to 4.5 g / l, preferably 1.5 to 2.5 g / l (calc. as Guanidine carbonate), a.
