Description

Diaphragma aus Papier o. dgl. für Primär- und Sekundärelemente und elektrolytische Zellen. Gegenstand der Erfindung ist ein Diaphragma für Primär- und Sekundärelemente und elektrolytische Zellen, welches geringen elektrischen Widerstand, gute Trennfähigkeit der Flüssigkeiten bzw. sichere Verhinderung des Kurzschlusses und genügende mechanische Festigkeit und Haltbarkeit besitzt. Es besteht aus einer dünnen feinporigen Schicht, wie z: B. Pergamentpapier, Fließpapier, Baumwollgewebe, welche beiderseits von einem Gitter oder einer gelochten Platte aus Hartgummi, Zelluloid o. dgl. eng umschlossen ist. Die mittlere Schicht übt die eigentliche Diaphragmenwirkung aus, das Gitter oder die gelochte Platte dient zur Versteifung und zum mechanischen Schutz der dünnen und empfindlichen Diaphragma--schicht. Die Gitter oder Platten können noch mit Rippen versehen sein, um die Elektroden in passendem Abstand voneinander zu halten. Es ist auch angängig, dem ganzen Diaphragma zu demselben Zweck Wellenform zu geben. Falls die innere Schicht voraussichtlich eine kürzere Lebensdauer haben wird als die Gitter oder Platten, empfiehlt es sich, sie leicht auswechselbar anzuordnen.Diaphragm made of paper or the like for primary and secondary elements and electrolytic cells. The invention relates to a diaphragm for primary and secondary elements and electrolytic cells, which have low electrical resistance, good separability of liquids and reliable prevention of short circuits and has sufficient mechanical strength and durability. It consists of one thin, fine-pored layer, such as parchment paper, blotting paper, cotton fabric, which on both sides of a grid or a perforated plate made of hard rubber, celluloid or the like is tightly enclosed. The middle layer exercises the actual diaphragm effect off, the grille or the perforated plate is used for stiffening and mechanical Protection of the thin and sensitive diaphragm layer. The grids or panels can also be provided with ribs to keep the electrodes at a suitable distance from each other to keep. It is also common to waveform the whole diaphragm for the same purpose admit. In case the inner layer is likely to have a shorter lifespan when used as the grids or panels, it is best to arrange them easily interchangeably.
