Description

Gummimembran als Scheider für Primär- und Sekundärelemente, elektrolytische Zellen, Filter u. dgl. Für die gute Wirksamkeit eines Scheiders ist es notwendig, daß er möglichst feine Poren enthält, damit kleinste Stoffteile am Durchwandern gehindert werden, ferner, daß die Anzahl der in dem Scheider enthaltenen Poren möglichst groß ist, damit sein elektrischer Widerstand gering ist und endlich, daß er gegen chemische und elektrolytische Wirkungen widerstandsfähig ist. Es sind beispielsweise Scheider bekannt, die aus Hartgummi bestehen, deren Fläche durch kurze Baumwollfäden, die der Stromleitung dienen, durchsetzt sind, wobei aber die so gebildeten Poren nicht eng genug sind, um auf die Dauer und mit Sicherheit ein Durchwandern von kleinen Teilen zu verhindern, zumal die Baumwollfäden sich herauslösen. Weiter werden Scheider in Form von Hartgummiröhren mit vielen sehr engen Schlitzen gebaut, die wohl das Durchtreten feiner Masseteile verhindern und gegen elektrolytische Wirkungen widerstandsfähig sind, die aber dem Strom verhältnismäßig hohen Widerstand entgegensetzen. Endlich sind Scheider aus schwammförmigem hollodium vorgeschlagen, die allerdings Poren von höchster Feinheit und größter Zahl besitzen, so daß in der Tat der elektrische Widerstand gering ist und feinste mechanische Teile zurückgehalten werden, die sich aber in ihrem Baustoff nicht als genügend widerstandsfähig erwiesen haben, weil die Zellulose des Scheiders an dessen posi- tiver Seite zersetzt wird. Das gleiche gilt für die als Scheider viel benutzten Holzbrett- chen. Diese Nachteile werden durch den Scheider nach vorliegender Erfindung ver- mieden, indem dafür als Baustoff schwamm- förmiges Gummi verwendet wird, welches durch Gerinnen von Latex oder aus Gummi- lösungen als Gel erzeugt und welches von unendlich vielen und so feinen Poren, daß ihr Durchmesser etwa in dem Gebiete kollo- idaler Größen liegt, durchzogen ist. Gummi- scheider dieser Art halten auch die feinsten Stoffteile zurück, setzen dem elektrischen Strom und dem Flüssigkeitsaustausch nur sehr geringen Widerstand entgegen, sind gegenüber der oxydierenden 'Wirkung des Sauerstoffes sowie gegenüber den meisten chemischen Agenzien von höchster Widerstandsfähigkeit und zeichnen sich zudem durch hohe Elasti- zität und Zerreißfestigkeit aus. Außer als Scheider sind solche Gummi- ' membranen auch als Filter für allgemeine chemische Zwecke gut geeignet. Diese hochporösen Scheider lassen sich auch imprägnieren, derart, daß sich mit ihrem Einbau im Bleisammler gleiche aufbessernde Wirkung, wie sie den Holzbrettchen eigen ist, erzielen läßt; zu diesem Zwecke können die Poren mit Holzextrakt, Phenol o. dgl. ge- tränkt werden. ä Der vorliegende Scheider kann in jeder beliebigen Form in das Element eingebaut werden, derart, daß er die Platte ganz oder teilweise umhüllt.Rubber membrane as a separator for primary and secondary elements, electrolytic cells, filters and the like. For the effectiveness of a separator, it is necessary that it contains the finest possible pores so that the smallest pieces of material are prevented from migrating through Scheider contained pores is as large as possible so that its electrical resistance is low and finite that it is resistant to chemical and electrolytic effects. For example, separators are known which are made of hard rubber, the surface of which is penetrated by short cotton threads that serve to conduct electricity, but the pores thus formed are not narrow enough to prevent small parts from migrating through in the long term and with certainty , especially since the cotton threads are peeling off. Separators are also built in the form of hard rubber tubes with many very narrow slots, which probably prevent the passage of fine mass parts and are resistant to electrolytic effects, but which offer relatively high resistance to the current. Finally, separators made of spongy hollodium have been proposed, which, however, have pores of the greatest fineness and the greatest number, so that the electrical resistance is indeed low and the finest mechanical parts are retained, which, however, have not proven to be sufficiently resistant in their building material because the cellulose of the separator at its positive tiver side is decomposed. The same goes for for the wooden boards, which are often used as separators chen. These disadvantages are caused by the Scheider according to the present invention by using sponge as a building material shaped rubber is used, which by coagulating latex or rubber solutions produced as a gel and which of infinitely many and so fine pores that their diameter roughly in the area of collo- of ideal sizes, is streaked. Rubber- Such separators also keep the finest Pieces of fabric back, put the electric Electricity and fluid exchange just a lot low resistance are opposite the oxidizing effect of oxygen as well as against most chemical Agents of the highest resistance and are also characterized by high elastic strength and tensile strength. Except as separators, such rubber 'membranes also act as filters for general well suited for chemical purposes. These highly porous separators can be also impregnate, in such a way as to deal with her Installation in the lead collector is the same improving Effect that is characteristic of the wooden boards is, can be achieved; for this purpose you can the pores with wood extract, phenol or the like. to be soaked. ä This separator can be used in any any shape can be built into the element in such a way that it completely or partially envelops the plate.
