Description
Verfahren zum Dichtmachen von porösen Elektrodenkörpern. Die vorliegende Erfindung betrifft ein Ver- fahren zum Dichtmachen der porösen Elektrodenkörper gewisser Elementtypen, ebenso wie die gewisser Elektrolysierapparate gegen Flüssigkeiten, um diesen Körpern ihre Eigenschaft der Gasionendurchlässigkeit oder der Absorption dieser Gase zu erhalten und ihnen eine gute elektrische Leitfähigkeit zu geben oder zu bewahren.Method for sealing porous electrode bodies. The present invention relates to a procedural for proofing the porous electrode body of certain item types, as well as certain Elektrolysierapparate against liquids to these bodies their property of the gas ion permeability or absorption to obtain these gases and to give them a good electrical conductivity, or to preserve.
Das Verfahren wird hauptsächlich gekennzeichnet durch eine Umhüllung des porösen Körpers mit einer Metallseife, sei es ein metallisches Oleomargarat (z. B. Zink-Oleomargarat) mit der Eigenschaft, auf dem porösen Körper eine kolloidale, pektisierte Haut zu bilden, die vom elektrischen Strom nicht zerstört wird, die Elektriziten gut leitet, dicht ist gegen Flüssigkeiten und durchlässig für Gasionen.The process is mainly characterized by an envelope the porous body with a metal soap, be it a metallic Oleomargarat (e.g. zinc oleomargarate) with the property of forming a colloidal, to form pectized skin that is not destroyed by the electric current Conducts electricity well, is impermeable to liquids and permeable to gas ions.
Die Metallseife kann z. B. wie folgt erhalten werden In x Liter Wasser, besonders in kochendem, löst man ioo Gramm Marseiller Seife, mischt dann diese Lösung in der Kälte mit einer etwa 4o°-Be-haltigen Zinkchloridlösung. Man erhält so eine Fällung von Zink-Oleomargarat oder Zinkseife.The metal soap can, for. B. obtained as follows In x liters of water, especially when it is boiling, dissolve 100 grams of Marseille soap and mix this solution in the cold with a 40 ° Be-containing zinc chloride solution. You get one like that Precipitation of zinc oleomargarate or zinc soap.
Die durch Abfiltrieren wiedergewonnene Fällung wird z. B. mit einem Spatel auf dem porösen Körper ausgebreitet und bildet so auf dem letzteren eine kolloidale, pektisierte Haut, die als Schutzüberzug wirkt, der zugleich unlöslich in Wasser, dicht gegen Flüssigkeiten, gasionendurchlässig, unzerstörbar durch den elektrischen Strom und guter Leiter der Elektrizität ist.The precipitate recovered by filtration is z. B. with a Spatula spread on the porous body, thus forming one on the latter colloidal, pecticized skin that acts as a protective coating that is also insoluble in water, impermeable to liquids, gas ion-permeable, indestructible due to the electric current and good conductor of electricity.
Dieser Überzug, der besonders für die poröse depolarisierende Kohle der positiven Elektrode gewisser Arten von Elementen verwendbar ist, schützt die poröse Kohle gegen Zutritt von Wasser des Elektrolyten und bewahrt dabei dem Element einen inneren Widerstand, der so klein wie möglich ist auf Grund der ungewöhnlich geringen Dicke dieser kolloidalen, pektisierten Haut und ihrer elektrischen Leitfähigkeit.This coating, which is specially made for the porous depolarizing charcoal the positive electrode of certain types of elements protects the porous carbon against ingress of water of the electrolyte and thereby preserves the element an internal resistance that is as small as possible due to the unusual small thickness of this colloidal, pecticized skin and its electrical conductivity.
Das pektisierte Kolloid von metallischem Oleomargarat kann sich auch durch Eintauchen des Körpers unter folgenden Bedingungen bilden.The pectized colloid of metallic oleomargarate can also form by immersing the body under the following conditions.
Der poröse Körper wird zuerst in eine Lösung Marseiller Seife getaucht, besonders in kochende; dieses Eintauchen muß so schnell ausgeführt werden, daß die Feuchtigkeit nicht Zeit hat, in die Masse einzudringen. Nach dem Eintauchen läßt man den Körper einige Augenblicke trocken und taucht ihn dann in die Lösung des Metallsalzes, z. B. Zinkchlorid.The porous body is first immersed in a solution of Marseille soap, especially in boiling; this immersion must be carried out so quickly that the Moisture does not have time to penetrate the mass. After dipping leaves dry the body for a few moments and then immerse it in the solution of the Metal salt, e.g. B. zinc chloride.
Durch Reaktion des Zinkchlorids mit der Seife bildet sich in den Poren der Außenteile des porösen Körpers Zink-Oleomargarat oder Zinkseife.The reaction of the zinc chloride with the soap forms in the pores of the outer parts of the porous body, zinc oleomargarate or zinc soap.
