Description

Verfahren zur Darstellung von Akkumulatorenplatten Die Herstellung von Akkumulatorenplatten, die aus einem Bleigerippe und aus deren Zwischenräume ausfüllender poröser Bleimasse bestehen, kann in der Weise erfolgen, daß in das Bleigerippe eine Bleilegierungsmasse eingegossen und dann das Begleitmetall aus der Legierung herausgelöst wird. Dieses Verfahren hat .den großen Nachteil, daß sich die Legierungsmasse beim Eingießen mit dem Bleigerippe legiert, so daß die Legierungsmasse beim Erkalten derartigen Spannungen unterworfen wird, daß in ihr Risse und Sprünge auftreten, so daß die Platten von vornherein unbrauchbar werden. Außerdem wird die Homogenität der Bleilegierungen durch das An- und Weglegieren des Bleigerippes sehr stark gestört, so daß beim Zerlegen der Legierung keine fest zusammenhängenden Massen mehr entstehen können.Process for the production of accumulator plates of accumulator plates, which consist of a lead frame and the spaces between them filling porous lead mass exist, can be done in such a way that in the Lead rib a lead alloy mass poured in and then the accompanying metal out the alloy is dissolved out. This method has the major disadvantage that the alloy mass is alloyed with the lead rib when pouring, so that the Alloy mass is subjected to such stresses when cooling that in her Cracks and fissures occur, so that the plates are unusable from the outset. In addition, the homogeneity of the lead alloys is increased by alloying on and off of the lead ribs very badly disturbed, so that no solid when the alloy is dismantled coherent masses can arise.

Es wurde nun gefunden, daß das Verfahren, Akkumulatorenplatten in der Weise herzustellen, daß man die Bleilegierungsmasse in ein Bleigerippe eingießt, sich vorteilhaft ausführen läßt, wenn man das Bleigerippe vor dem Eingießen der Legierung mit einer Schutzschicht überzieht, die einerseits den Angriff des Bleilegierungsmetalls auf das blanke Bleimetall verhindert und andererseits einen mehr oder minder schlechten Wärmeleiter darstellt, so daß die Abkühlung des höher schmelzenden Bleinatriums, wie es z. B. in diesem Falle angewendet wird, rascher erfolgt, als die Erwärmung des Bleis, wodurch ein Schmelzen des Bleigerippes überhaupt nicht mehr eintritt. Die Schutzschicht kann beispielsweise aus Oxyden oder Salzen bestehen, und zwar nimmt man am zweckmäßigsten die des Bleis selbst. Man verwendet z. B. Bleioxyd-, Bleisuperoxyd-, Bleisulfid-, Bleisulfatverbndungen, die gleichzeitig auch noch den Vorteil haben, daß sie beispielsweise bei Herstellung von Anodenplatten bei der elektrolytischen Formation zu Bleisuperoxyd oxydiert werden und somit kein weiterer Zwischenprozeß zur Entfernung der Schutzschichten notwendig wird. Gleichzeitig wird dadurch eine Hohlraumbildung vermieden. Die weitere Verarbeitung der Platten kann dann in verschiedenster Weise ausgeführt werden.It has now been found that the method, accumulator plates in made by pouring the lead alloy mass into a lead frame, can be carried out advantageously if you remove the lead frame before pouring the Alloy is covered with a protective layer, which on the one hand prevents the lead alloy metal from attacking on the bare lead metal and on the other hand a more or less bad one Represents heat conductor, so that the cooling of the higher melting lead sodium, how it z. B. is used in this case, takes place faster than the heating of the lead, which means that the lead ribs no longer melt at all. The protective layer can consist, for example, of oxides or salts it is best to take that of the lead itself. B. lead oxide, Lead peroxide, lead sulphide, lead sulphate compounds, which at the same time also have the Have the advantage that they are used, for example, in the manufacture of anode plates in the electrolytic formation to be oxidized to lead peroxide and thus no further Intermediate process for removing the protective layers is necessary. At the same time will thereby avoiding the formation of cavities. The further processing of the plates can then be carried out in various ways.
