Description

Verfahren zur Herstellung von Kupferoxydplatten für galvanische Elemente Es sind Verfahren zur Herstellung von Kupferoxydplatten für galvanische Elemente bekannt, bei denen die'Festigkeitder Platten dadurch erzielt wird, daß durch chemische Einflüsse mit oder ohne Wärmezufuhr eine partielle Reduktion von Kupferoxyd vorgenommen wird. Diese Verfahren haben entweder in der Art ihrer Ausführung oder in der Ausnutzbarkeit der aktiven Masse Nachteile.Process for the production of copper oxide plates for galvanic elements There are processes for the production of copper oxide plates for galvanic elements known, in which die'Festigkeit the plates is achieved by chemical Influences with or without the supply of heat, a partial reduction of copper oxide is carried out will. These procedures have either in the way they are carried out or in the usability the active mass disadvantages.

Gemäß der Erfindung wird :ein selbsttätiges Erhärten der Kupferoxydplatten dadurch erreicht,' daß bei :der Herstellung der Platten Magnesiazemente als Bindemittel benutzt werden. Zu diesem Zweck kann man dem Kupferoxyd Magnesiumoxyd zusetzen. Nach Zugabe von Chlormagnesiumlösung ist die Masse schmier- bzw. preßbar und kann in diesem Zustand in bequemer Weise in Kupferrahmen oder sonstige Masseträger ein.- oder aufgeschmiert oder :ein- oder aufgepreßt werden. Durch Bildung von Magnesiazement erhärten diese Platten nach einiger Zeit.According to the invention: an automatic hardening of the copper oxide plates achieved by 'that in: the production of the panels, magnesia cements as binders to be used. For this purpose, magnesium oxide can be added to the copper oxide. After adding magnesium chlorine solution, the mass can be lubricated or pressed in this state in a convenient way in copper frames or other mass carriers. or smeared on or: be pressed in or on. Through the formation of magnesia cement these plates harden after a while.

Bekannt ist, bei der Herstellung von Kupferexydplatten für galvanische Elemente dem Kupferoxyd keramische Bindemittel, wie Ton, Schamotte o. dgl., beizumischen, doch müssen diese Massen zur Erhärtung gebrannt werden. Bei Benutzung von Ma;gnesiazement als Bindemittel .erübrigt sich dieses Brennen.It is known in the production of copper oxide plates for electroplating Elements of the copper oxide ceramic binders, such as clay, chamotte or the like, to be added, but these masses have to be fired to harden. When using magnesia cement as a binding agent, this burning is unnecessary.

Um die Platte zur Erreichungtinerbesseren Regenerierbarkeit porös zu gestalten und um bei Verwendung geringster Mengen Magnesiazementes die fertige Mischung plastisch zu bekommen, können .entsprechende Mengen in Wasser nicht löslicher Flüssigkeiten (beispielsweise Xylol) oder Emulsionen in angepaßter Menge zugesetzt werden.To achieve better regenerability, the plate is porous and to create the finished product when using the smallest amounts of magnesia cement To get the mixture plastic, corresponding amounts cannot be more soluble in water Liquids (for example xylene) or emulsions added in an appropriate amount will.
