Description

Letrifft:Verfahren zur Vorbereitung von Dtahl und Aluminium für eine Lackierung oder Beschichtung mit Kunsatoffen durch eine Nasspolitur, Vor einer Lackierung des Aluminium und d-#s Stahls is.t es üblichgdie Oberflächen entweder mit Deckschichten zu überziehen oder sie aufzurauheneDie beckschichten bestehen häufig aus den Verbindungen der Metalle sowie aus Verbindungen den Chro» und Phosphors* Durch diese Verbindungen werden die Deckzchichten grau bis grün gefärbt*Sie i.,erdz#n aus diesem Grunde nicht mit transparenten Lacken oder Folien überzogen. Durch die Aufrauhung der Oberflächen zum Beispiel mittels Drahtbürsten werden Glanz und Korrosionsbeständigkeit geminderte Die Aufbriftgung von Lacken und Folien aus Kunststoff scheitert meist an der zu7geringen Haft -estig!-.eit.Applies to: Procedure for preparing steel and aluminum for a Painting or coating with plastics by wet polishing, before painting For aluminum and steel, it is common for the surfaces to have either top layers The basin layers often consist of the compounds of metals as well as from compounds of chromium and phosphorus * by these compounds the top layers are colored gray to green * they i., erdz # n for this reason not covered with transparent lacquers or foils. By roughening the surfaces For example, wire brushes reduce the gloss and corrosion resistance The application of varnishes and foils made of plastic usually fails because of the inadequate quality Hold on! -. Eit.

Es wurde nun überraschend gefunden,dass das HaftvermÖgen.der Oberflächen bedeutend verbessert werden kanntwenn sie nasspoliert werden@ Vorteilhaft ist bei dieser Arbeitsweise auchldass die nasspolierten Oberflächen besonders glatt und glänzend sind,sodass bei Aufbringung transparenter Filme eine sehr dekorative Wirkung er-zielt wird* Zweckmässig werden die Metalle zunächst trockenpoliert und danach in zwei Stufen nasspoliert.Bei der zweiten Nasspolitur kann auf die Zugabe von FestkÖrpern verzichtet werdenund mit einer Salziösung zuq Beispiel einer 1-,lagnesiumsulfatlugung gearbeitet werden* It has now been found, surprisingly, that the adhesion of the surfaces can be significantly improved if they are wet-polished @ It is also advantageous in this way of working that the wet-polished surfaces are particularly smooth and shiny, so that a very decorative effect is achieved when transparent films are applied the metals are first dry-polished and then wet-polished in two stages. In the second wet polishing, the addition of solids can be dispensed with and a saline solution can be used for example a 1, magnesium sulfate solution *
