Description

Verfahren zur Herstellung poröser Platten Zusatz zum Patent 895146 .Gegenstand .der Erfindung isst ,die Anwendung des im Patent 895 146 beschriebenen Verfahrens zum, Herstellen poröser Platten aus thermopfias.tischem Kunststoffen,auf andere Werkstoffe, die unter Anwendung vom Wärme oberflächlich erweicht werden können, wie z. B. Glas und O'uariz.Process for the production of porous plates Addition to the patent 895146. Subject of the invention is the application of the process described in the patent 895 146 for the production of porous plates from thermo-plastic plastics on other materials which can be softened on the surface with the application of heat, such as B. Glas and O'uariz.

Es ist ibekannt, Schichten jdieser Stoffe in Körnerform- unter Anwendung von Wärme ,zu Platten zusammenzusinterm; aber diese Platten lassen sich nur einigermaßen dick z. B. als Filterplatten herstellen, um,d,das Gefüge solcher Platten und ihre Porosität ist im allgemeinen nicht in allen Teilen der Platte gleich,. Diese Nachteule werden bei denn Verfahren nach der Erfindung vermieden. Nach dieser wird Üer Werkstoff Ader genannten Art in der Forme vom Geweben verwendet, die aus Fasern des Werkstoffs hergestellt sind. Diese Gewebe werden awfeinandergelegt und unter Anwendung vom Wärme und Druck zusammengepreßt und so zu einer porösen Platte vereinigt.It is known to use layers of these substances in granular form of warmth, sintered together into plates; but these plates can only be reduced to a certain extent thick z. B. produce as filter plates to, d, the structure of such plates and their Porosity is generally not the same in all parts of the plate. That night owl are avoided in the method according to the invention. After this becomes about material This type of vein is used in the form of woven fabrics, which are made from fibers of the material are made. These tissues are placed together and using the Heat and pressure pressed together and thus combined into a porous plate.

Durch die Anwendung der Gewerbe, ,in denen der Werkstoff in feinfädiger Form gano gleichmäßig über die Fläche des Gewebes verteilt ist, wird eiirre vo,l@lkomm.e,n gleichmäßige Verteilung der Poren über die ganze Fläohe und über ,den Queriscbnli.tt der aus den Geweben hergestellten Platte erreicht.By applying the trades, in which the material in fine thread Form is evenly distributed over the surface of the fabric, eiirre vo, l @ lkomm.e, n even distribution of the pores over the whole area and over , the queriscbnli.tt of the plate made from the tissues reached.

Durch Idas Erwärmen der Ciruwdbe auf eine ausreichend holhe' aber unterhalb Jets Schmelizpunktes des Werkstoffs liegende Temperatur werden die einzelnen Fasern der Gewebelagen oberflächlich so weit erweicht, .daß bei Anwendung eines nach der Art des Werkstoffis zu wählenden ausreichenden Drucks die Fasern der Gewebelagen aneinanderhaften und sich zu einer porösen Platte vereinigen. Niaeh diesem Verfahren gdi:ngt insbesondere idas Hersteillen auch sehr dünner poröser Platten, in .denen ,bei! großem, Porenvolumen @seihr kleine Poren. sehr gleichmäßig über ärie Fläche und über den Querschnitt der Platte verteiil@t ,sind.By Idas warming the Ciruwdbe to a sufficiently holhe 'but The temperature is below jet's melting point of the material Fibers of the fabric layers softened so far on the surface that when using a Depending on the type of material, sufficient pressure to be selected is the fibers of the fabric layers stick together and unite to form a porous plate. Niaeh this procedure In particular, it is necessary to manufacture even very thin porous plates in them ,at! large, pore volume @very small pores. very evenly over the surface and distributed over the cross-section of the plate.
