PATENTAMT.PATENT OFFICE.
LJm das Abfallen der Elektrodenmasse aus den Bleigittern und die hierdurch entstehenden Nachtheile zu verhüten, sind poröse Scheidewände bezw. Schutzhüllen verwendet worden, die aus den verschiedensten Stoffen bestehen. Von faserigen Stoffen wurde im Besonderen Torfmoos allein oder auch mit einem Bindemittel, z. B. Gips, benutzt. Das Torfmoos besitzt aber nicht die Fähigkeit, den Einwirkungen des Elektrolyten auf die Dauer zu widerstehen, und verwandelt sich in ziemlich kurzer Zeit zu schlammiger, nicht poröser Masse, durch welche die sich bildenden Gase nicht unbehindert entweichen, bezw. der Elektrolyt zwischen den Elektroden nicht kreisen kann. Wenn auch einerseits der zu dem Torfmoos als Bindemittel zugesetzte Gips die Schlammbildung etwas verzögert, so geht doch andererseits dieser mit dem Elektrolyten schädliche Verbindungen ein, wodurch die Scheidewände an einzelnen Stellen zerstört werden können, so dafs an diesen durch Abfallen von Körnern oder Bildung pulverförmiger Verästelungen der wirksamen Masse Kurzschlufs im Sammler entstehen kann.LJm the fall of the electrode mass from the lead grids and the resulting To prevent disadvantages, porous partitions are resp. Protective covers have been used, which consist of a wide variety of materials. Of fibrous fabrics in particular Peat moss alone or with a binder, e.g. B. plaster is used. That owns peat moss but not the ability to withstand the effects of the electrolyte in the long term, and turns into a muddy, non-porous mass through which the gases formed do not escape unhindered, respectively. the electrolyte between the Electrodes cannot rotate. Even if on the one hand that of the peat moss as a binding agent added gypsum delays the sludge formation, but on the other hand it goes with it the electrolyte builds up harmful compounds, causing the septum in individual places can be destroyed, so that on them by falling off grains or formation powdery ramifications of the effective mass short circuit can arise in the collector.
Im Gegensatz hierzu besitzt eine geprefste Schutzhülle aus Torffaserkohle den Vortheil, dafs sie den Einwirkungen des Elektrolyten in viel höherem Mafse widersteht und infolge ihrer Struktur, die bei dem Torfmoos sehr bald verloren geht, weder den Umlauf des Elektrolyten noch das Entweichen der Gase behindert. Ferner besitzt sie eine genügende Elasticität, um den Ausdehnungen und Zusammenziehungen der wirksamen Elektrodenmasse zu folgen und so im steten Zusammenhang mit dieser zu bleiben.In contrast to this, a pressed protective cover made of peat fiber charcoal has the advantage that it withstands the action of the electrolyte to a much greater extent, and consequently its structure, which is very soon lost in the peat moss, neither the circulation of the Electrolytes still prevent the gases from escaping. Furthermore, she has a sufficient Elasticity to accommodate the expansions and contractions of the effective electrode mass to follow and to stay in constant connection with it.
Die zu verwendende Torffaser wird zunächst verkohlt, und zwar wird dies bis zu einem bestimmten Grade zweckmäfsig mit verdünnter Schwefelsäure bewirkt. Es ist zwar bekannt, Torffaser mit Schwefelsäure zu behandeln. Jedoch hatte dies, bisher lediglich den Zweck, feinere Fasern zu erzielen und diese spinnfähig zu machen, bezw. das später nachfolgende Bleichen einzuleiten. Dieses wird im vorliegenden Falle nicht beabsichtigt.The peat fiber to be used is first charred, and indeed this will be up to a certain point Effectively effected with dilute sulfuric acid. It is known to treat peat fiber with sulfuric acid. However, up to now this has only had the purpose of achieving finer fibers and making them spinnable to make, respectively. initiate subsequent bleaching. This is in the present Trap not intended.
Zur Herstellung der geprefsten Schutzhüllen oder Platten aus Torffaserkohle wird zunächst die Torffaser zu lockerer Wolle verarbeitet, wobei etwa darin enthaltene Torfmoosstücke oder körnige Fremdkörper entfernt werden. Hierauf wird die möglichst staubfreie. Torffaserwolle einer unvollständigen Verkohlung, zweckmäfsig mit 40 procentiger Schwefelsäure unterworfen, jedoch nur so lange, dafs die Struktur der Faser erhalten bleibt. Nach Beendigung dieses Prozesses wird die so gewonnene Faserkohle tüchtig mit Wasser ausgewaschen, getrocknet, gewalkt und dann während längerer Zeit (etwa 10 Stunden) unter hohem Druck (etwa 500 Atm.) zwischen beheizten Platten geprefst.For the production of the pressed protective covers or plates from peat fiber charcoal, first the peat fiber is processed into loose wool, with pieces of peat moss contained in it or granular foreign bodies are removed. This will be as dust-free as possible. Peat fiber wool incomplete charring, expediently with 40 percent sulfuric acid subject, but only so long that the structure of the fiber is retained. After completion During this process, the carbon fiber obtained in this way is thoroughly washed out with water, dried, drummed and then under for a long time (about 10 hours) high pressure (about 500 atm.) pressed between heated plates.
Da diese gepreisten Platten von ziemlicher Härte sind, werden sie, bevor sie als Schutzhülle Verwendung finden, in Schwefelsäure aufgeweicht, wodurch die Platten aufquellen und elastisch werden. Es entstehen ferner zwischen den vorher fest zusammengeprefsten FasernSince these praised panels are quite hard, they are used as a protective cover before being used Find use, softened in sulfuric acid, causing the plates to swell and become elastic. It also occurs between the previously firmly compressed fibers
geeignete Zwischenräume, durch welche der Elektrolyt unbehindert kreisen, bezw. die Gase nach aufsen gelangen können.suitable spaces through which the electrolyte circulates freely, respectively. the gases can reach the outside.
