Description

Kontaktreinigungsverfahren Die vorliegende Erfindung betrifft ein Kontaktreinigungsverfahren zum Reinigen von Silber in alkalischen Lösungen mittels Aluminiumkontaktes.Contact cleaning method The present invention relates to a Contact cleaning process for cleaning silver in alkaline solutions using Aluminum contact.

Derartige Kontaktreinigungsverfahren mittels Aluminiumkontaktes sind an sich bekannt. Man hat bei diesen Verfahren meist alkalische Lösungen, z. B. Natriumbicarbonat enthaltende Lösungen, mit oder ohne Zusatz von Seifenlösungen verwendet.Such contact cleaning processes by means of aluminum contact are known per se. In this process, mostly alkaline solutions are used, e.g. B. Sodium bicarbonate containing solutions, with or without the addition of soap solutions.

Den Gegenstand der vorliegenden Erfindung bildet nun eine Verbesserung derartiger Natriumbicarbonat und Seife enthaltender Lösungen durch Zusatz von Aldehydzucker. Dieser Zusatz bewirkt eine schnellere und gründlichere Reinigung der Silbergeräte und verzögert weiter auch das Wiederanlaufen dieser Gegenstände. B:eispie1 r o g :eines Gemisches, bestehend aus 92,5 0/0 Na H C 0s, 5 % gepulv. med. Seife, 2i/2 % Traubenzucker, werden in i 1 Wasser in einem Aluminiumgefäß gelöst und die Gegenstände eingelegt.The subject of the present invention is now an improvement such solutions containing sodium bicarbonate and soap by adding aldehyde sugar. This addition causes a faster and more thorough cleaning of the silver devices and further delays the restart of these items. B: eispie1 r o g : a mixture consisting of 92.5 0/0 Na H C 0s, 5% powdered. med. Soap, 2i / 2 % Grape sugar, are dissolved in i 1 water in an aluminum vessel and the objects inserted.
