Description
Matratzen bzw. Matten oder Filze aus synthetischen oder Naturfasern Die Erfindung bezieht sich auf Matratzen bzw. Matten oder Filze, die sich durch besonders gute wärmeisolierende Eigenschaften auszeichnen. Sie schafft solche Matratzen bzw. Matten oder Filze, die in besonders vorteilhafter Weise zur thermischen Isolation von mit hohen Temperaturen arbeitenden Öfen oder Motoren, insbesondere von Flugzeugmotoren od. dgl., geeignet sind.Mattresses or mats or felts made of synthetic or natural fibers The invention relates to mattresses or mats or felts, which are through particularly good heat-insulating properties. She creates such mattresses or mats or felts, which are particularly advantageous for thermal insulation of ovens or engines operating at high temperatures, especially aircraft engines or the like, are suitable.
Für solche Verhältnisse eignen sich die üblichen aus Fasern hergestellten Matten nicht, weil bei Temperaturen von einigen hundert Graden die Wirkung des Phänomens des Wärmeaustausches durch Konvektion gegenüber der des Wärmeaustausches durch Strahlung in vernaehlässigbarer Weise zurücktritt.The usual ones made from fibers are suitable for such conditions Mats do not, because at temperatures of a few hundred degrees the effect of the phenomenon heat exchange through convection versus heat exchange through radiation resigns in a negligible manner.
Unter solchen Voraussetzungen können sich deshalb die Fasern selbst erhitzen, worauf sie die von ihnen aufgenommene Wärmestrahlung ihrerseits ausstrahlen. Gewisse der für Wärmeisolierungen verwendeten Fasern, wie Asbestfasern, Glasfasern und Quarzglasfasern, besitzen insbesondere den Nachteil, daß ihr Absorptionsfaktor und ihre ausstrahlende Wirkung bei Temperaturen von 100 bis 1000° C erheblich (von 0,9 auf 0,5) ansteigt, wodurch die Erhitzung und die Wiederausstrahlung der Wärme von der heißen Wand nach der kalten Wand hin noch mehr begünstigt wird.Under such conditions, the fibers can therefore themselves heat, whereupon they in turn radiate the thermal radiation they have absorbed. Certain of the fibers used for thermal insulation, such as asbestos fibers, glass fibers and quartz glass fibers, in particular, have the disadvantage that their absorption factor and their radiating effect at temperatures of 100 to 1000 ° C is considerable (from 0.9 to 0.5) increases, causing heating and re-radiation of heat is even more favored from the hot wall to the cold wall.
Diese Nachteile der bekannten wärmeisolierenden Matten bzw. Matratzen oder Filze aus Kunststoff oder Naturfasern werden gemäß der Erfindung dadurch vermieden, daß die Fasern, aus welche die Matten bzw. Matratzen oder Filze bestehen, mit einer Metallschicht von geringer Absorptionsfähigkeit und geringer Wärmeausstrahlfähigkeit überzogen sind.These disadvantages of the known heat-insulating mats or mattresses or felts made of plastic or natural fibers are avoided according to the invention, that the fibers from which the mats or mattresses or felts are made with a Metal layer of low absorption capacity and low heat radiation capacity are coated.
Die Verwendung von mit einem solchen Metallüberzug bekleideten Fasern für die Herstellung der Matten oder Filze hat die Wirkung, daß einerseits die durch die heiße Wand ausgesandte Wärmeausstrahlung nach dieser hin zurückreflektiert wird und außerdem eine wesentlich geringere Erhöhung der Temperatur der Fasern erfolgt und daß diese ihrerseits, weil sie mit dem Metallüberzug von geringer Ausstrahlfähigkeit versehen sind, nur wenig Wärmeenergie nach der kalten Wand hin abgeben.The use of fibers clad with such a metal coating for the production of mats or felts has the effect that on the one hand the through the heat radiation emitted by the hot wall is reflected back towards it and there is also a much smaller increase in the temperature of the fibers and that for their part, because they are coated with metal and have a poor emissivity are provided, only give off a little heat energy towards the cold wall.
Unter den Metallen, welche zur Herstellung der Überzüge auf den Fasern geeignet sind, sind - ohne daß aber die Erfindung auf die Verwendung dieser Metalle beschränkt wäre - Gold, Silber, Platin und Aluminium zu nennen. Das Metallisieren der Fasern kann durch Aufdampfen des Metalls unter Vakuum oder durch Aufsprühen desselben ebenfalls unter Vakuum sowie schließlich, insbesondere im Falle von Silber, Gold und Platin, auf chemischem Wege durch Auffällen eines aus diesen Metallen bestehenden Niederschlages durch Zersetzung eines Salzes der betroffenen Metalle erfolgen.Among the metals used to make the coatings on the fibers are suitable - but the invention does not apply to the use of these metals would be limited - to name gold, silver, platinum and aluminum. The metallizing the fibers can be produced by vapor deposition of the metal under vacuum or by spraying the same also under vacuum and finally, especially in the case of silver, Gold and platinum, chemically by precipitation of one of these metals Precipitation take place by decomposition of a salt of the affected metals.
