Description

Verfahren zur Herstellung von Filtern oder Filtertüchern in Form von Geweben, Geflechten oder Filzen aus Kautschukfäden oder -streifen Es ist bekannt, Fäden und Streifen aus Kautschuk, der weich vulkanisiert ist, zu Geweben, Geflechte oder Filzen zu verarbeiten.Process for the production of filters or filter cloths in the form of Woven fabrics, braids or felts made from rubber threads or strips It is known Threads and strips of rubber that is softly vulcanized into fabrics, braids or felting.

Insbesondere ist schon vorgeschlagen worden, derartige Gewebe, Geflechte oder Filze als Diaphragmen, Filter und Filtertücher, insbesondere für Drebfilter, zu verwenden, da ich, im Gegensatz zu beispielsweise Tonfilterplatten, Geflechte aus Kautschukfäden in größeren Bahnen herstellen und bequemer auf len Trommelumfang aufbringen und befestigen lassen.In particular, it has already been proposed to use such fabrics, braids or felts as diaphragms, filters and filter cloths, especially for Dreb filters, to use because, in contrast to, for example, clay filter plates, I use braids Manufacture from rubber threads in larger lengths and more conveniently on the drum circumference apply and attach.

Gegenstand der Erfindung sind Filter in Form von aus Kautschukfäden oder -streifen gebilfleten Geweben, Geflechten oder Filzen, die hart vulkanisiert sind. Durch die Hartvullianisation des Kautschuks wird eine bedeutend höhere Viderstandsfäligkeit solcher Filter gegen den Angriff starker Säuren, Alkalien und anderen Chemikalien erreicht. The invention relates to filters in the form of rubber threads or strips of formed fabric, braid or felt that are hard vulcanized are. The hard vulcanization of the rubber results in a significantly higher resistance such filter against the attack of strong acids, alkalis and other chemicals achieved.

Gemäß der Erfindung werden solche Filter dadurch hergestellt, daß die: aus einer zur Erzeugtung von Hartgummi geeigneten Gummimischung gespritzten Fäden zunächst vorvulkanisiert werden, so daß sie formbeständig, aber noch elastisch und biegsam sind. In die Gummifäden können natürlich auch Metalldrähte oder Textilfäden eingelegt sein. According to the invention, such filters are produced in that die: injected from a rubber compound suitable for producing hard rubber Threads are first pre-vulcanized so that they retain their shape but are still elastic and are flexible. Of course, metal wires or textile threads can also be used in the rubber threads be inserted.

Darauf werden die Filter aus den vorvulkanisierten Fäden gewebt, geflochten oder gewirkt. Handelt es sich um Gummifäden ohne Einlagen, so muß bei der Herstellung der Filter Sorge getragen werden, daß die Fäden sich nicht spannen, da die fertigen Gewebe sich sonst zusammenziehen; man kann dies dadurch erreichen, daß die Gummifäden unter Beilage nicht elastischer Fäden verflochten, gewebt oder gewirkt werden, wobei die nicht elastischen Fäden später wieder entfernt werden können.The filters are then woven and braided from the pre-vulcanized threads or wrought. In the case of rubber threads without deposits, it must be used during manufacture the filter care must be taken that the threads do not stretch because the finished Otherwise tissue will contract; this can be achieved by using the rubber threads are interwoven, woven or knitted with the addition of non-elastic threads, whereby the non-elastic threads can be removed again later.

Nach der Bildung der Filtergewebe usw. werden diese z. B. unter Anwendung von Wärme und Druck ausvulkanisiert; damit nehmen sie eine starre Form (Hartgummi) an und werden gegen chemische Einwirkungen in hohem Maße unempfindlich. After the formation of the filter fabric, etc., these z. B. using vulcanized by heat and pressure; so they take a rigid form (hard rubber) and become highly insensitive to chemical effects.
