Description

Nach der im Patent 895 146 beschriebenen Erfindung wird' eine poröse Platte aus thermoplastischem Kunststoff in der Weise hergestellt, daß zwei oder mehr Lagen von Geweben aus dem thermoplastischen Kunststoff, wie sie z. B. als Filtertücher im Verkehr sind, aufeinandergelegt und unter oberflächlicher Erweichung des Kunststoffs mittels erhöhter Temperatur oder eines Lösungsmittels in flüssiger oder Dampfform zusammengepreßt werden.According to the invention described in patent 895 146, a porous sheet made of thermoplastic Plastic produced in such a way that two or more layers of fabrics made of the thermoplastic material, as z. B. as filter cloths are in traffic, placed on top of each other and with superficial softening of the plastic by means of elevated temperature or a solvent in liquid or vapor form will.

Nun hat sich überraschenderweise gezeigt, daß nach dem gleichen Verfahren, unter Anwendung der gleichen technischen Mittel, also unter Erweichung mittels erhöhter Temperatur oder eines Lösungsmittels in flüssiger oder in Dampfform, auch eine einzelne Lage eines Gewebes aus thermoplastischem Kunststoff durch Preßdruck in eine dünne poröse Platte verwandelt werden kann.Now, surprisingly, it has been shown that the same procedure, using the same technical means, i.e. with softening by means of increased temperature or one Solvent in liquid or vapor form, even a single layer of a fabric made of thermoplastic material by pressing into a thin porous plate can be transformed.

Eine so hergestellte poröse Platte hat ein ganz anderes Gefüge als das Gewebe, aus dem sie her-A porous plate produced in this way has a completely different structure than the fabric from which it is made.

gestellt ist. Sie ist nicht weich und schmiegsam wie dieses, sondern steif und fest, aber sehr biegsam und elastisch, sehr zähe und reißfest und nahezu unzerbrechlich.is posed. It is not soft and pliable like this one, but stiff and firm, but very flexible and elastic, very tough and tear-resistant and almost unbreakable.

Unter Anwendung des erfindungsgemäßen Verfahrens lassen sich so aus einer einzigen Gewebelage besonders dünne feinporige Platten von großer Festigkeit herstellen, die als Filter und als Diaphragmen sehr vorteilhaft zu verwenden sind. Wird eine solche dünne poröse Platte erwärmt gebogen, so behält sie, abgekühlt, ihre Form.Using the method according to the invention, a single fabric layer Manufacture particularly thin, fine-pored plates of great strength that can be used as filters and diaphragms are very beneficial to use. If such a thin porous plate is bent when heated, this is how it keeps its shape when cooled.
