Description

Sammlerscheider Man hat bereits vorgeschlagen, zwischen den Platten von elektrischen Sammlern Trennplatten oder Scheider aus Glasgespinst ,anzubringen. Diese Platten bestanden aus mehreren Glasgespinstschleiern aus Glasfäden .von praktisch endloser Fadenlänge, wie sie durch Abziehen eines Glasfadens von der schmelzflüssiger Glasmasse und Aufhaspeln .auf einer Trommel gewonnen werden. Die aus mehreren Schichten bestehenden Platten wurden mit .wasserlöslichen Bindemitteln getränkt und dann unter Pressung getrocknet, so daß harte, widerstandsfähige Platten erhalten wurden, die zwischen die Akkumulatorenplatten gebracht wurden. Beim Eintauchen in die Akkumulatorensäure wurden die Klebstoffe aufgelöst, die filzartigen Platten- verloren ihren Halt und konnten auseinanderfallen.Sammlerscheider One has already suggested between the plates of electrical collectors, separating plates or separators made of woven glass to be attached. These panels consisted of several woven glass veils made of glass threads .of practical endless thread length, such as that obtained by pulling a glass thread from the molten Glass mass and rewinder .on a drum are obtained. The one from several layers Existing panels were soaked with .wasser-soluble binders and then under Press dried, so that hard, resistant panels were obtained that were brought between the accumulator plates. When immersed in the accumulator acid the adhesives were dissolved, the felt-like plates lost their hold and could fall apart.

Man hat ferner bereits vorgeschlagen, derartige Platten ,aus Glasgespinst mit einem Durchmesser von weniger als. 0,03 mm herzustellen. Man hat die Platten entweder aus langfaserigem Glasgespinst oder .aus kurzfaserigem, stapelfaserartigein Glasgespinst hergestellt und die Glasfasern durch Bindemittel miteinander verkittet. Auch hat man Scheider aus Glasgespinstgewebe hergestellt, die aus Glasgespinstgarn bestanden.It has also already been proposed that such plates be made of woven glass with a diameter less than. 0.03 mm. You have the plates either made of long-fiber fiberglass or .from short-fiber, staple fiber-like Glass fiber is made and the glass fibers are cemented together with binders. Separators were also made from fiberglass, those from fiberglass yarn passed.

Demgegenüber betrifft die vorliegende Erfindung Sammlerscheider aus Glasgespinst, die sich dadurch auszeichnen, daß Schichten aus stapelfaserartigem Glaswollgespinst von geringem. Durchmesser mit Schichten aus langfaserigem Glasgespinst vereinigt sind. Lediglich bei der Herstellung werden die Glasgespinstschichten durch ein Bindemittel zusammengehalten, das während der -Verwendung des Scheiders durch den Elektrolyten aufgelöst wird. Gegenüber den bisherigen Sammlerplatten .aus Glasgespinst zeigen die Platten nach der vorliegenden Erfindung den Vorteil einer feinen, gleichmäßigen Porung, so daß Sperrholzplatten überflüssig sind. W eiterhin wird trotz der feinen Porung ein verhältnismäßig großer -Gesamtporenquerschnitt erzielt, so daß die lonenwanderung den geringsten Widerstand findet. Obwohl das Bindemittel durch den Elektrolyten aufgelöst wird, haben die Platten infolge der angewendeten langen Glasfaser einen guten Zusammenhalt, so daß bei großer Porenoberfläche ein dichtes Anliegen an die Bleiplatten gewährleistet und das Herabfallen von Bleischlamm und damit ein Kurzschluß vermieden wird.In contrast, the present invention relates to collector separators Glass fiber, which is characterized by the fact that layers of staple fiber Fiberglass spun of little. Diameter with layers of long fiber glass fiber are united. The fiberglass layers only get through during production a binder held together during the use of the separator the electrolyte is dissolved. Compared to the previous collector's plates. Made of woven glass show the plates according to the present invention the advantage of a fine, uniform Pore size so that plywood panels are superfluous. It continues despite the fine Pore a relatively large total pore cross-section achieved, so that the ion migration finds the least resistance. Although the binder through the electrolyte is dissolved, the plates have a due to the long glass fiber used good cohesion, so that with a large pore surface a close fit to the Lead plates guaranteed and the falling of lead sludge and thus a short circuit is avoided.

Zur Herstellung der Trennplatten -nach der vorliegenden Erfindung wird z. B. Glasgespinst von praktisch endloser Fadenlänge zu einem Schleier von gewünschter Stärke zerzupft und darauf eine Schicht von feinfaserigem, stapelfaserartigem Glaswollgespinst ausgebreitet, wie es z. B. durch Zerstäuben eines schmelzflüssigen Glasstrahles mit einer Fadenstärke von etwa o, o i 8 mm und einer Fadenlänge von z. B. 2 cm erhalten wird. Darauf wird wieder eine Schicht von langfaserigem, stärkerem Glasgespinst gebracht. Die Schichten werden mit einem im Elektrolyten löslichen Klebemittel, z. B. einer Dextrin-oder Stärkelösung, getränkt und dann unter schwachem Druck und Erwärmen getrocknet, so daß zusammenhängende, mehr oder weniger hart gepreßte Platten entstehen, die eine hohe Schnittfestigkeit aufweisen, sich also gut in die verlangten Größen schneiden lassen und die eine starke Druckbelastung zulassen.For making the partition plates according to the present invention is z. B. Glass web of practically endless thread length to a Veil of the desired thickness plucked and a layer of fine-grained, Staple fiber-like glass wool web spread out, as it is, for. B. by atomization a molten glass jet with a thread thickness of about o, o i 8 mm and a thread length of z. B. 2 cm is obtained. Then another layer of Brought long-fiber, stronger fiberglass. The layers are marked with an im Electrolyte soluble adhesive, e.g. B. a dextrin or starch solution, soaked and then dried under low pressure and heating, so that coherent, More or less hard-pressed panels are created that have a high cut resistance have, so they can be easily cut into the required sizes and the one allow heavy pressure loads.

Sobald diese Platten in die Akkumulatorensäure getaucht werden, wird der die einzelnen Fasern zusammenhaltende Klebstoff aufgelöst. Hierdurch wird ein außerordentlich porenreicher Körper erhalten, der den Elektrolyten leicht hindurchläßt.As soon as these plates are immersed in the accumulator acid, the adhesive holding the individual fibers together dissolved. This becomes a extremely pore-rich body obtained, which allows the electrolyte to easily pass through.

Durch verschiedenartige Dichte der inneren stapelfaserartigen Glaswollgespinstlagen kann. man den Trennplatten nach der vorliegenden Erfindung jede gewünschte Porosität verleihen. Hierdurch wird weder der Einbau erschwert noch fallen die Platten auseinander, wenn diese ihren Halt verloren haben.Due to the different density of the inner staple fiber-like glass wool fiber layers can. any desired porosity can be given to the partition plates according to the present invention to lend. This neither makes installation difficult nor does the panels fall apart, when these have lost their hold.
