Description

Verfahren zum Vernickeln ohne Nickelanoden Es ist bekannt, bei der Vernickelung Anoden aus Aluminium anzuwenden, die von Diaphragmen aus Stoffgewebe umgeben sind. Jedoch haben sich die Stoffdiaphragmen praktisch nicht bewährt, da sie mechanisch sehr empfindlich sind und die Verunreinigung des Elektrolyts durch die an der Anode entstehenden Produkte nicht mit Sicherheit verhindern.Process for nickel plating without nickel anodes It is known in the Nickel-plating anodes made of aluminum apply to those of diaphragms made of fabric are surrounded. However, the fabric diaphragms have practically not proven themselves because they are mechanically very sensitive and the contamination of the electrolyte by do not prevent with certainty the products created at the anode.

Tondiaphragmen der üblichen Beschaffenheit, deren Anwendung gleichfalls schon bekannt ist, haben sich als bedeutend günstiger erwiesen, bieten aber dem Stromdurchgang einen verhältnismäßig hohen Widerstand. Es hat sich nun gezeigt, daß man Tondiaphragmen erhalten kann, die gut stromdurchlässig, dabei aber mechanisch widerstandsfähig sind, wenn der Ton bei einer Temperatur von etwa zroo° gebrannt wird. Ferner hat es sich als günstig erwiesen, die Tondiaphragmen mit Stoffbeuteln zu umgeben, um bei etwaigem Bruch des Diaphragmas eine Verunreinigung des Elektrolyts zu verhindern.Clay diaphragms of the usual nature, their application as well is already known, have proven to be significantly cheaper, but offer the Current passage has a relatively high resistance. It has now been shown that you can get clay diaphragms that are good current-permeable, but mechanical are resistant when the clay is fired at a temperature of around zroo ° will. It has also proven to be beneficial to use cloth bags for the clay diaphragms to avoid contamination of the electrolyte if the diaphragm breaks to prevent.

Schließlich hat es sich noch gezeigt, daß man die Arbeitsweise -von Nickelbädern mit Aluminiumanoden in den erfindungsgemäßen Diaphragmen noch dadurch verbessern kann, daß man dem Elektrolyt noch Tartrate zusetzt.Finally, it turned out that the working method of Nickel baths with aluminum anodes in the diaphragms according to the invention still thereby can be improved by adding tartrates to the electrolyte.
