Description

Auskleidungen von Amalgam-Elektrolysezellen Bekanntlich sind bei Einrichtungen zur elektrolytischen Herstellung von Ätzalkalilaugen nach dem Amalgamverfahren die Teile, welche mit den dabei auftretenden=Flüssigkeiten und Gasen in Berührung kommen, mit natürlichem oder synthetischem Gummi ausgekleidet. Vor allem die Hypochlorit, Salzsäure und Chlorat enthaltende Salzlösung sowie die chlorhaltigen Gase greifen den Gummi stark an, so daß die Auskleidungen öfters ausgebessert und erneuert werden müssen. Dies führt zu einer zeitweisen Stilllegung der betreffenden Einrichtungen, so daß die Wirtschaftlichkeit der Laugenherstellung infolge der Instandsetzungskosten und des Erzeugungsausfalles ungünstig beeinflußt wird. Es wurde gefunden, daß dies vermieden werden kann, wenn die Auskleidungen mit mindestens einem festhaftenden Film bedeckt sind, der gegen die mit ihm in Berührung kommenden Flüssigkeiten und Gase beständig ist. Besonders vorteilhaft haben sich für den Film Phenolformaldehydharze bzw. Kitte, Wasserglas und Kitte aus solchen u. dgl. erwiesen. Im einfachsten Ausführungsfalle wird der Film durch das übliche Anstreichen oder Aufspritzen erzeugt. Man kann aber auch dünne Folien aus den genannten widerstandsfähigen Stoffen mit dem Gummi der Auskleidung verbinden, z. B. durch Aufkleben, Rufsintern, Aufschweißen usw. In jedem Fall muß erreicht werden, daß die Folie vollkommen dicht ohne Lufteinschlüsse mit der Gummiunterlage verbunden ist. Es hat sich in der Technik gezeigt, daß die gemäß der Erfindung durch einen Überzug geschützten Auskleidungen um ein Vielfaches länger haltbar sind; es gelingt sogar bei rechtzeitiger Ausbesserung oder Erneuerung des Films eine Zerstörung der Gummierung auf die Dauer praktisch vollkommen zu verhindern.Linings of amalgam electrolytic cells are known to be used in facilities for the electrolytic production of caustic alkali solutions using the amalgam process Parts that come into contact with the liquids and gases that occur in the process, lined with natural or synthetic rubber. Especially the hypochlorite, Salt solution containing hydrochloric acid and chlorate as well as the chlorine-containing gases take effect the rubber strongly, so that the linings are often repaired and renewed have to. This leads to a temporary shutdown of the facilities concerned, so that the economy of the lye production as a result of the repair costs and the generation failure is adversely affected. It has been found that this Can be avoided if the linings with at least one firmly adhering Film are covered against the liquids and in contact with it Is resistant to gases. Phenol-formaldehyde resins have proven particularly advantageous for the film or putty, water glass and putty from such and the like. In the simplest execution case the film is produced by the usual painting or spraying. But you can also thin foils made of the aforementioned resistant materials with the rubber of the Connect lining, e.g. B. by gluing, sintering, welding, etc. In each Case must be achieved that the film completely tight without Air pockets is connected to the rubber pad. It has been shown in technology that the according to the invention by a coating protected linings many times over have a longer shelf life; it even succeeds if it is repaired or renewed in good time of the film to virtually completely prevent destruction of the rubber coating in the long term.
