Description

Scheider für Bleisammler und elektrolytische Zellen. . Es wurde mehrfach vorgeschlagen, Scheider für Bleisammler in der Weise herzustellen, daß poröse Stoffe mit organischen im plastischen oder flüssigen Zustand befindlichen Bindemitteln gemischt werden, worauf die Mischung einem dem Bindemittel entsprechenden Härtevorgang unterworfen wird. Dieses Herstellungsverfahren hat den Nachteil, daß beim Mischen die porösen Körper von der plastischen oder flüssigen Masse mit einem Häutchen überzogen oder durchtränkt werden, so daß die Porosität der Scheider stark vermindert oder sogar aufgehoben wird. Die Erfindung bezweckt, obigen Nachteil zu vermeiden. Nach derselben werden zerkleinerte poröse Stoffe, wie Holz; Sägespäne, Bimstein, gebrannter Ton mit- einem pulverförmigen organischen Bindemittel, wie Parasit, natürliches oder künstliches Harz, Asphalt, vulkanisierter Gummi, gemischt und erhöhtem Druck oder erhöhter Temperatur oder beiden, gegebenenfalls unter Zufügung geeigneter Stoffe, unterworfen, wodurch das Bindemittel zu einem festen Körper zusammenbackt; in welchem die porösen Stoffe eingebettet sind. Hierbei ist die Temperatur und der Druck stets dem verwendeten Bindemittel anzupassen, damit letzteres nicht entweder durch zu große Dünnflüssigkeit oder durch zu hohem Druck in die porösen Körper eindringt.Separator for lead collectors and electrolytic cells. . It was repeated several times proposed separating lead collectors in such a way that porous materials with organic binders in a plastic or liquid state are mixed, whereupon the mixture a hardening process corresponding to the binder is subjected. This manufacturing method has the disadvantage that when mixing the porous bodies are covered with a membrane by the plastic or liquid mass or soaked, so that the porosity of the separator is greatly reduced or is even canceled. The invention aims to avoid the above disadvantage. To these become crushed porous substances, such as wood; Sawdust, pumice, burnt Clay with a powdered organic binder such as parasite, natural or artificial resin, asphalt, vulcanized rubber, mixed and increased pressure or elevated temperature or both, if necessary with the addition of suitable substances, subjected, whereby the binder cakes together into a solid body; in which the porous substances are embedded. Here the temperature and the pressure are always to adapt to the binder used, so that the latter does not either through large thin liquid or too high pressure penetrates into the porous body.

Es ist bekannt, Scheider aus pulverförmigen Stoffen durch Erhitzung unter Vermeidung des Zusammenschmelzens herzustellen. Doch wurden hierzu nur anorganische (sogenannte keramische) Stoffe und Bindemittel verwendet und die Erhitzung auf mehr als i ooo° getrieben, wobei alles Organische verbrannt wäre.It is known to divider from powdered substances by heating while avoiding melting together. But only inorganic ones were used for this purpose (so-called ceramic) fabrics and binders are used and heating to more drifted as i ooo °, whereby everything organic would be burned up.

Beispiel. ioo Teile pulverisierter vulkanisierter Kautschuk, io Teile pulverisierter Sch-,vefel, 55o Teile Holzmehl werden innig miteinander vermischt, so daß ein gleichförmiges Pulver entsteht. Dieses Pulver wird einer Temperatur von i2o bis 16o° C ausgesetzt und unter einem Druck von ioo Atm. etwa zwei Stunden gehalten.Example. 100 parts powdered vulcanized rubber, 10 parts pulverized sheep, vefel, 55o parts wood flour are intimately mixed together, so that a uniform powder is produced. This powder is a temperature of Exposed to i2o to 16o ° C and under a pressure of 100 atmospheres. held for about two hours.

Werden andere pulverförmige Bindemittel verwendet, so richtet sich selbstverständlich die Temperatur und der Druck nach ihren Eigenschaften. Man kann selbstverständlich den porösen Körpern und dem Bindemittel noch wasser- oder säurelösliche Stoffe zusetzen, die nach der Härtung wieder herausgelöst werden, wodurch die Porosität des Scheiders noch weiter erhöht wird.If other pulverulent binders are used, this is determined of course the temperature and the pressure according to their properties. One can Of course, the porous bodies and the binding agent are still water- or acid-soluble Add substances that are released again after hardening, which reduces the porosity of the separator is increased even further.
