Description

Gegenstand eines älteren Patents ist ein Verfahren zur Herstellung von mattiertem Zinnblech durch galvanisches Verzinnen von Stahlblech und kathodische Nachbehandlung des Zinnüberzuges in einer wäßrigen Alkalimetalidichromatlösung, das dadurch gekennzeichnet ist, daß vor der kathodischen Nachbehandlung das Blech kurz auf eine Temperatur unterhalb des Schmelzpunktes von Zinn erwärmt und unmittelbar anschließend abgeschreckt wird. Ein in dieser Weise behandeltes Zinnblech dunkelt nicht nach, wenn es beispielsweise zum Einbrennen eines Lacküberzuges erwärmt wird.The subject of an earlier patent is a process for the production of matt tinplate by electroplating Tinning of sheet steel and cathodic aftertreatment of the tin coating in an aqueous one Alkali metal dichromate solution, which is characterized in that before the cathodic aftertreatment the sheet is briefly heated to a temperature below the melting point of tin and is quenched immediately afterwards. Tinplate treated in this way does not darken after, for example, when it is heated to bake a varnish coating.

Es hat sich nun herausgestellt, daß das Blech mindestens auf eine Temperatur von über 130° C erwärmt werden muß. Dadurch wird nämlich gewährleistet, daß sich auf der Oberfläche des Zinnüberzuges eine aus kristallinem Zinnoxid bestehende Oberflächenschicht bildet, die ein späteres Nachdunkeln verhindert. Bei Temperaturen unter 130° C bildet sich lediglich eine aus amorphem Zinnoxid bestehende Oberflächenschicht, die jedoch nachIt has now been found that the sheet metal has at least a temperature of over 130.degree must be heated. This ensures that it is on the surface of the tin coating a surface layer consisting of crystalline tin oxide forms, which later darkens prevented. At temperatures below 130 ° C, only one of amorphous tin oxide is formed existing surface layer, which however after

dunkelt. Falls die Wärmebehandlung, bei fortlaufend bewegtem Blech durchgeführt wird, muß das Blech mindestens auf eine Temperatur von 204° C erwärmt werden.darkens. If the heat treatment, at continuous moved sheet metal is carried out, the sheet metal must be heated to a temperature of at least 204 ° C will.
