Description

Vorrichtung zur Herstellung von porösen Separatoren, Filtern, Diaphragmen u. dgl. Es ist bekannt, poröse Separatoren, Filter, Diaphragmen u. dgl. aus porösem oder porösem und nichtporösem Weich- bis Hartkautschuk mittels Doppelfolienformen, inwelchendas eingestreute Pulver vulkanisiert wird, herzustellen. Um eine besonders gleichmäßige und widerstandsfähige poröse K.autschukmass.e zu erhalten, ist bereits vorgeschlagen worden, die teilweise vulkanisierten Weichbis Hartkautschukpartikelchen durch Rühren bei erhöhter Temperatur, etwa 4o his 8o"; unter Vermeidung von Feuchtigkeit in feiner Verteilung zu. erhalten und in diesem Zustande in die Formen fließen zu lassen. Zum Zwecke der Vulkanisation wurden ein oder zwei Doppelfolienformen zwischen Paarenvon Blei-Antimon-Platten aufgehängt, welche mit in gewissen Abständen eingeschalteten H,ei.zpl,atten .eine Vulkanisationspresse bildeten, die in einen Doppelvulkanisator eingeführt wurde.Device for the production of porous separators, filters, diaphragms It is known to make porous separators, filters, diaphragms and the like made of porous or porous and non-porous soft to hard rubber by means of double-film molding, in which the sprinkled powder is vulcanized. To one special Obtaining uniform and resistant porous rubber compounds is already a thing of the past has been proposed, the partially vulcanized soft to hard rubber particles by stirring at an elevated temperature, about 4o to 8o "; avoiding moisture in fine distribution too. and in this state flow into the forms permit. For the purpose of vulcanization, one or two double sheet molds were placed between Pairs of lead-antimony plates are suspended, which are switched on at certain intervals H, ei.zpl, atten. Formed a vulcanization press, which in a double vulcanizer was introduced.

Die Erfindung betrifft eine Vorrichtung, durch welche die bisherige Arbeitsweise viel wirtschaftlicher .durchgeführt werden kann. Erfindungsgemäß werden die nicht zusammengepreßten unverbundenen Doppelfolienformen in einem Kasten stapelförmig aufeinandergelegt, wobei der Deckel des Kastens nach unten gepreßt wird, bis sämtliche Doppelfolien gleichmäßig auf das gewünschte Volumen zusammengepreßt sind. Zweckmäßig werden im Kasten verstellbare Anschlagstücke für den Deckel vorgesehen, wodurch der Druck in einfacher und einwandfreier Weise eingestellt werden kann. Der Kasten kann entweder in einen Vulkanisator eingefahren oder selbst als Vulkanisationspresse mit Heizplatten ausgebildet werden. Es ist unter diesen Umständen vorteilhaft, zwischen den Folien oder einer Anzahl derselben zwecks Erhaltung ihrer Form Metallplatten vorzusehen.The invention relates to a device through which the previous Way of working can be carried out much more economically. Be according to the invention the uncompressed, unconnected double-sheet forms in a box in a stack placed on top of each other, the lid of the box is pressed down until all Double foils are evenly compressed to the desired volume. Appropriate adjustable stop pieces for the lid are provided in the box, whereby the pressure can be adjusted in a simple and flawless manner. The box can either be run into a vulcanizer or as a vulcanization press itself be formed with heating plates. In these circumstances it is advantageous to choose between the foils or a number of the same are metal plates in order to maintain their shape to be provided.

Durch die beschriebene Vorrichtung kann eine drei- bis viermal so große Anzahl von Doppelfolien in demselben Raum des Vulkanisators. als früher vulkanisiert werden, wodurch eine Ersparnis an Arbeit und an Dampf erzielt wird.» Zugleich wird aber auch ein anderer Vorteil erreicht, der sich daraus ergibt, daß nur dünne Metallfolien zu vulkanisieren sind, deren Gesamtdicke nur einen kleinen Teil der früh-er verwendeten Blei-Antimon-Platten ausmacht. Man kann nämlich starke Separatoren durch einfache Vulkanisation der Doppelfolien in der heißen Luft des Doppelvulkanisators erzielen.The device described can do this three to four times large number of double foils in the same space of the vulcanizer. than previously vulcanized which saves work and steam. " At the same time will but also achieved another advantage, which results from the fact that only thin metal foils are to be vulcanized, the total thickness of which is only a small part of that used earlier Lead-antimony plates. You can namely use strong separators by simply vulcanizing the double foils in the hot air of the double vulcanizer achieve.
