Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Verfahren zum Verbessern der Temperaturbeständigkeit von Filtergewebe aus Glasfasern' Es ist bekannt, Glasfasern gegen thermische Beständigkeit zu verbessern.'' Process for improving the temperature resistance of filter fabric from glass fibers' It is known to improve glass fibers against thermal resistance.

Hierzu werden z. B. Säurewaschungen durchgeführt und anschließende Temperungen zur Veredelung angesetzt.For this purpose z. B. acid washes carried out and subsequent Tempering for finishing is set.

Weiterhin ist bekannt, nach der Säurewaschung zur Verbesserung der mechanischen Eigenschaften der Glasfaser Chromverbindungen anzulagern und zwar durch Behandlung der Fasern oder des Gewebes mit Metallhydrooxiden und anschließender Erhitzung z. B. auf 800 - 900 00.It is also known after the acid wash to improve the to deposit mechanical properties of the glass fiber chromium compounds through Treatment of the fibers or the fabric with metal hydroxides and then Heating z. B. to 800 - 900 00.

Diese Vergütungen reichen jedoch nicht aus, um z. B.However, this remuneration is not sufficient to, for. B.

eine Glasfaser so mechanisch zu verfestigen, das sie als Heißgasfilter z. B. in der Entstaubungstechnik eingesetzt werden können.to mechanically strengthen a glass fiber in such a way that it acts as a hot gas filter z. B. can be used in dedusting technology.

Die obig beschriebenen Ausbildungsformen haben bisher lediglich ausgereicht, um die Gewebe mit den bekannten Vergütungsmethoden zur Abschirmung von heißen Strahlen und Arbeitsvorgängen einzusetzen.The forms of training described above have so far only been sufficient around the fabric with the well-known compensation methods for shielding against hot rays and implement work processes.

Um die bekannten Glasfasergewebe für die Heißgasfilterung nützen zu können, wird erfindungsgemäß folgende Veredlungstechnologie vorgeschlagen: Der Glasfaserfaden oder das Filtergewebe werden durch eine Spezial-Säurewaschung unter Zusatz von flüssiger Kieselsäure mit großer spezifischer Oberfläche und/oder heißen Säurebad extrahiert und in einer weiteren erfindungsgemäßen Behandlungsstufe wird das Gewebe mit Netallkompleilösungen des Aluminiums, Titans, Zirkons, Chroms, Nickels, und/oder Kobalt durch Intensivtränkung erfindungdgemäß weiter vergütet, vorzugsweise unter Druck, so daß eine intensive Metallanlagerung auch bis zum Kern der Faser gewährleistet ist.To use the well-known glass fiber fabric for hot gas filtering the following finishing technology is proposed according to the invention: The glass fiber thread or the filter fabric is cleaned by a special acid wash with the addition of liquid Extracted silica with a large specific surface and / or hot acid bath and in a further treatment step according to the invention, the tissue is treated with complete metal solutions of aluminum, titanium, zirconium, chrome, nickel and / or cobalt through intensive impregnation According to the invention further remunerated, preferably under pressure, so that an intensive Metal deposition is also guaranteed up to the core of the fiber.

Als Koiplexbildner sollten erfindungsgemäß organische Kompleibildner, wie vorzugsweise Glyzin (Glykokoll), Anwendung finden.According to the invention, organic complexing agents should be used as complexing agents, such as preferably glycine (glycocolla) are used.

In einer weiteren Vergütungsstufe wird das Material auf 600 - 1000 00 Je nach Materialbeschaffenheit erhitzt, so daß durch diese erfindungsgemäße Behandlung das Glas und/oder Keramikfasergewebe gleichmäßig bzw. intensiver veredelt wird, als es bei den bekannten Verfahren bisher möglich war.In a further remuneration level, the material is set to 600 - 1000 00 Heated depending on the nature of the material, so that this treatment according to the invention the glass and / or ceramic fiber fabric is refined evenly or more intensively, than was previously possible with the known methods.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, Jedoch ohne von dem Grundgedanken abzuweichen, eine mehrstufige vorzugsweise 3-stufige Veredlung zur Verbesserung von Glasfasern entsprechend obiger Beschreibung durchzuführen.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, but without deviating from the basic idea, a multi-level preferably 3-stage refinement to improve glass fibers according to the description above perform.
