Description
Verfahren zur Herstellung von Elektroden für alkalische Sammler mittels einer Strangpresse Die Elektroden für alkalische Sammler stellt man in der Weise her, daß man Metall-bzw. Metalloxydpulver mit entsprechenden Zusätzen mischt, sie dann in geeigneten Formen zu Pastillen preßt, in Taschen einfalzt und diese zu Platten verarbeitet; oder man stopft mit einer komplizierten Einfüllmaschine mit Dosiervorrichtungen abwechselnd Nickelhydroxydmasse und Nickelflitterchen in perforierte, vernickelte Stahlblechröhren ein und setzt .diese ebenfalls zu Platten zusammen.Process for the production of electrodes for alkaline collectors by means of an extrusion press The electrodes for alkaline collectors are placed in this way ago that one metal or. Mixing metal oxide powder with appropriate additives, they then pressed into pastilles in suitable molds, folded into pockets and these into plates processed; or you stuff with a complicated filling machine with dosing devices alternating nickel hydroxide mass and nickel tinsel in perforated, nickel-plated Sheet steel tubes and put them together to form plates.
Nach dem im Patent 123 5I2 beschriebenen Verfahren kann man zur Herstellung von Elektroden für Bleisammler die aktive Masse, wie z. B. Bleioxyd, Bleisuperoxyd, um einen Bleikern herumpressen. Durch Abbinden der aktiven Masse erhält dann die Elektrode ihre Festigkeit. Zur Herstellung von Elektroden für alkalische Sammler läßt sich dieses Verfahren nicht anwenden, da den aktiven Massen keine Stoffe zugesetzt werden, die ein nachheriges Abbinden und Festwerden der gepreßten Formkörper bedingen. Dementsprechend entsteht beim Verpressen von alkalischen Massen selbst bei hohem Druck nicht ein -gutgeformter Körper bzw. ein Band, Strang usw., sondern eine Masse von nicht genügendem Zusammenhalt. Es `wurde nun gefunden, daß man Elektroden für alkalische Sammler herstellen kann, wenn man die mittels der Strangpresse hergestellten Stränge, Bänder usw. aus alkalischen aktiven Massen direkt ohne Anwendung einer besonderen Preßvorrichtung vermittels des beim Austritt aus der Matrize noch vorhandenen Drucks in die Röhrchen oder Taschen einpreßt. Es ist dazu eine entsprechende Haltevorrichtung für die Aufnahme de(r Röhrchen und Taschen. anzubringen.The process described in patent 123 5I2 can be used to produce of electrodes for lead collectors the active mass, such. B. lead oxide, lead peroxide, press around a lead core. By setting the active material, the Electrode their strength. For the production of electrodes for alkaline collectors This method cannot be used because no substances have been added to the active masses which cause a subsequent setting and solidification of the pressed moldings. Correspondingly, when compressing alkaline masses, even high Pressure is not a well-formed body or a band, strand, etc., but a mass of insufficient cohesion. It has now been found that electrodes can be used for Can produce alkaline collectors if you use the extrusion press Strands, ribbons, etc. of alkaline active masses directly without the application of any special pressing device by means of what is still present at the exit from the die Pressure into the tubes or pockets. There is a corresponding holding device for this to hold the tubes and bags.
Bei der Herstellung von Röhrchenelektroden besteht z. B die Haltevorrichtung aus einer drehbaren Trommel, deren Achse parallel zur Preßrichtung verläuft und in welche Löcher in kreisförmiger Anordnung eingebracht sind zur Aufnahme der Röhrchen, in die die aktive Masse eingepreßt wird. Die Trommel sitzt unmittelbar vor der Matrize. Nachdem ein Röhrchen gefüllt ist, dreht sich die Trommel ruckweise weiter, so daß das nächste Röhrchen vor die Matrizenöffnung kommt usw.In the manufacture of tube electrodes, for. B the holding device from a rotatable drum, the axis of which is parallel to the pressing direction and in which holes are made in a circular arrangement to accommodate the tubes, into which the active mass is pressed. The drum sits directly in front of the die. After a tube is filled, the drum continues to rotate in jerks, so that the next tube comes in front of the die opening, etc.
Als Strangpressen kommen sowohl Schnekkenstrangpressen als auch Kolbenstrangpressen in Frage. Im ersten Falle kann das Pulver kontinuierlich am hinteren Teile der Schnecke eingefüllt werden. Im zweiten Falle werden die aktiven Massen zweckmäßig zu Pulver- Briketten vorgepreßt. Die so dargestellten Materialien=haben den Vorteil großer Gleichmäßigkeit; Homogenität und dementsprechend größerer Leistungsfähigkeit.Both screw extrusions and piston extrusions can be used as extrusions in question. In the first case, the powder can be continuous at the rear of the screw be filled. In the second case, the active masses are expediently converted into powder Briquettes pre-pressed. The materials represented in this way = have the advantage of great uniformity; Homogeneity and, accordingly, greater efficiency.
