Abstract
Description
Formheständiges Preßband Für Einsätze mit hohen Hitzeeinwirkungen z.B. bei der Herstellung von Tischlerplatten, Spanplatten, Fournituren u.ä. Arbeitsgängen unter hohem Prcßdruck werden an die Stütz- und Förderbänder außergewöhnliche mechnische und thermische Ansprüche gestellt. Shape-retaining press belt For applications with high effects of heat e.g. in the production of blockboard, chipboard, fittings, etc. Operations Under high pressure, the support and conveyor belts are subjected to exceptional mechanical engineering and thermal demands.
Dic hohen Temperaturen in Verbindung mit hohen Preßdrücken verlangen für die Zusamniensetzung der Preßbänder besondere Voraussetzungen, wobei aucll noch eine genügende Flexibilität für die Umleitung um relativ kleine Umlenkaggregate verlangt werden muß.They require high temperatures in connection with high pressing pressures for the composition of the press belts special requirements, whereby aucll still sufficient flexibility for the diversion around relatively small deflection units must be requested.
Es hat sich gezeigt, daß Bänder mit durchgehenden Deckschichten diese Bedingungen nur mangelhaft erfüllen können, weil die Deckauflagen die vielseitigen Krafteinwirkungen von Druck und Zug besonders unter den großen Temperaturdifferenzen von Raumtemperatur bis über 200 ° C, die im Verlauf vieler industrieller Herstellungsvcrfahren in kurzzeitigen Folgen entstehen können, auf längere Dauer nicht ohne Sch;idigung verkraften können. Auflagen von Dickendimensionen von ausreichender Stabilität wirken sich auf die Flexibilität des Tuches sehr ungünstig aus, so daß auch in dieser Hinsich sehr enge Grenzen gesetzt sind.It has been shown that tapes with continuous cover layers this Conditions can only inadequately meet because the top layers are versatile Force effects of pressure and tension, especially under the large temperature differences from room temperature to over 200 ° C, which is common in many industrial manufacturing processes can arise in short-term consequences, in the longer term not without damage can cope with. Requirements of thickness dimensions of sufficient stability act has a very unfavorable effect on the flexibility of the cloth, so that in this respect too very narrow limits are set.
Es ist nun gefunden worden, daß diese Mängel weitgehend beseitigt werden1 wenn anstelle einer festen, mehr oder weniger dicken Deckschicht Kunstharpartikel in das Garn- oder Gewebegefüge eingelagert und durch eine kunststoffgerechte Nachbehandlung wie Fixieren oder Sintern verfestigt werden. Diese Einlagerungen können durch ein- oder mehrmaliges Tränken der spannungslos durch eine Lösung oder Dispersion geführten Garne (vor dem Verweben) oder der fertigen Gewebe (als Rohgewebe) erreicht werden. Durch diese Einlagerungen wird nicht nur eine erhöhte Stabilität der Gewebe erreicht, es wird vielmehr auch eine bedeutende Verbesserung der Haltbarkeit gegen die beschriebenen Beanspruchungen erreicht, ohne die Flexibilität ungünstig zu beeinflussen. Ein leichtes Kalandern nach dem ersten Tränkvorgang kann den Einlagerungseffekt günstig beeinflussen.It has now been found that these deficiencies are largely eliminated are1 if instead of a solid, more or less thick top layer synthetic resin particles embedded in the yarn or fabric structure and through a post-treatment suitable for plastics such as fixing or sintering are solidified. These storages can be or repeated impregnation of the tension-free guided through a solution or dispersion Yarns (before weaving) or the finished fabric (as raw fabric) can be achieved. These deposits not only increase the stability of the tissue, rather, it will also be a significant improvement in durability over those described Stresses achieved without adversely affecting flexibility. A simple Calendering after the first impregnation process can have a beneficial effect on the storage effect.
Derartige Einlagerungen müssen in Relation zur Gewebedicke und zum Garntiter gehalten werden. rm allgeicinen sollten 40 - 100 g je m2 Gewebefläche nicht überschritten werden. Bcsonders geeignet für derartige Behandlungen sind aufgrund der hohen Hitzebeständig keit die Fluorverbindungen wie Polytetrafluorethylen oder die Polyimide, die in geeigneten Dispersionen oder Lösungen im llandel erhältlich sind.Such deposits must be in relation to the tissue thickness and to the Yarn titers are kept. rm allgeicinen should be 40 - 100 g per m2 of fabric surface not be exceeded. Particularly suitable for such treatments are due to the high heat resistance the fluorine compounds such as polytetrafluoroethylene or the polyimides, which are available in suitable dispersions or solutions in llandel are.
Ein wesentlicher Vorteil dieses Verfahrens besteht auch darin, daß hierdurch eine nachträgliche einseitige oder heidseitie Beschichtung zur Erzielung einer bestimmten Oberflächenstruktur nicht ausgeschlossen wird.A major advantage of this method is that as a result, a subsequent one-sided or two-sided coating to achieve this a certain surface structure is not excluded.
