Description
Die Erfindung bezieht sich auf eine Einrichtung zur Vermeidung des Nachkochens elektrischer Sammler mit negativer Kastenplatte mit einer aus leitendem Stoff bestehenden gelochten Abdeckung des mit wirksamer Masse gefüllten Gitters und, einer lösliche Metalle, insbesondere Antimon, enthaltenden positiven Elektrode. Es hat sich nämlich gezeigt, daß, falls die positiven Elektrodenplatten freiliegende Rahmen oder sonstige Trägerteile aus hochprozentigem Hartblei besitzen, eine größere Menge von Antimon während des Betriebes auf die Bleche'niedergeschlagen wird und dadurch das sogenannte Nachkochen der negativen Platten bewirkt. Dieser Nachteil wird nach der Erfindung dadurch vermieden, daß die insbesondere aus Blei oder Bleilegierung bestehende gelochte Abdeckung der negativen Kastenplatte an ihrer gesamten Außenseite unter Freilassung der Löcher mit einem nicht leitenden, festhaftenden, dichten und elektrolytbeständigen Stoff, insbesondere Hart- oder Weichgummi, lückenlos bekleidet ist. Gegenüber solchenThe invention relates to a device for avoiding post-boiling electrical collector with negative box plate with one made of conductive material perforated cover of the grid filled with effective mass and, a soluble one Positive electrode containing metals, in particular antimony. It has been shown that that if the positive electrode plates exposed frames or other support parts made of high-percentage hard lead, a large amount of antimony is deposited on the metal sheets during operation and thereby causes the so-called reboiling of the negative plates. This disadvantage is avoided according to the invention in that the particular from Lead or lead alloy existing perforated cover of the negative box plate its entire outside, leaving the holes free with a non-conductive, firmly adhesive, dense and electrolyte-resistant material, especially hard or soft rubber, is completely covered. Compared to such
25' negativen Platten, deren Abdeckungen aus nicht leitendem Stoff, wie Celluloid, hergestellt sind, wird dabei der Vorteil einer besseren Stromverteilung in der bei der Einrichtung nach der Erfindung benutzten negativen Kastenplatte mit einer aus leitendem Stoff bestehenden gelochten Abdeckung des mit wirksamer Masse gefüllten Gitters beibehalten."25 'negative plates with their covers off Non-conductive fabric, such as celluloid, will have the advantage of being better Current distribution in the negative used in the device according to the invention Box plate with a perforated cover made of conductive material for the effective Maintain the mass of the filled grid. "
Wie Versuche ergeben haben, wird bei der Einrichtung nach der Erfindung ein das Nachkochen bewirkender Niederschlag von aus der positiven Elektrode stammenden oder auf andere Weise in den Elektrolyt gelangten Metallen, insbesondere Antimon, auf den perforierten Bleiblechen der Kastenplattg mit ■ Sicherheit vermieden. Dieser Vorteil ist von größter praktischer Bedeutung insbesondere dann, wenn die positive Elektrode mit Rücksicht auf die erforderliche mechanische Festigkeit verhältnismäßig hohe Prozentsätze, insbesondere von Antimon, enthält. Der Überzug auf der negativen Kastenplatte kann in an sich bekannter Weise, z.B. durch Bestreichen und Bespritzen mittels Gummilösung oder wäßriger Kautschukemulsionen und nachfolgendem Trocknen und gegebenenfalls Vulkanisieren auf die Außenseite der Abdeckung aufgebracht werden. Es kann auch ein volles Bleiblech in beliebiger Weise mit einer Gummischicht bedeckt und dann erst zusammen mit dem überzug fein gelocht werden. Bei der Einrichtung nach der Erfindung ist es wesentlich, daß, im Gegensatz zu den bisher bekannten isolierenden Überzügen, der Überzug vollkommen undurchlässig für den Elektrolyten ist. Ebenso wird die beste Wirkung dann erzielt, wenn man im Gegensatz zu den bisher bekannten isolierenden Überzügen den Überzug bei der Einrichtung nach der Erfindung lückenlos aufbringt.As tests have shown, the device according to the invention is a After boiling-causing precipitate originating from the positive electrode or Metals that got into the electrolyte in other ways, especially antimony, on the perforated ones Lead sheets of the box platg ■ avoided with certainty. This advantage is of of greatest practical importance especially when the positive electrode with consideration relatively high percentages of the required mechanical strength, in particular of antimony. The coating on the negative box plate can be carried out in a manner known per se, for example by painting and spraying by means of rubber solution or aqueous rubber emulsions and subsequent drying and optionally Vulcanizing can be applied to the outside of the cover. It can also use a full lead sheet in any way covered with a rubber layer and only then finely perforated together with the cover. In the device according to the invention, it is essential that, in contrast to the previously known insulating coatings, the coating completely impermeable to the Electrolyte is. Likewise, the best effect is achieved when you contrast to the previously known insulating coatings after the coating at the facility the invention applies seamlessly.
