Abstract
Flexibel verformbares VIP aus geschüttetem Kernmaterial, dadurch gekennzeichnet, dass als Filtermaterial ein ein- oder mehrlagiges Vliesmaterial, vorzugsweise aus thermoplastischen Kunststoff verwendet wird.Flexibly deformable VIP made of poured core material, characterized in that a single or multi-layer nonwoven material, preferably made of thermoplastic material is used as the filter material.
Description
Die Erfindung beschreibt flexible, verformbare Vakuumdämmpaneele (auch Vakuumisolationspaneele, nachfolgend „VIP”) aus geschüttetem Kernmaterial.The invention describes flexible, deformable Vakuumdämmpaneele (also vacuum insulation panels, hereinafter "VIP") of poured core material.
Üblicherweise werden VIPs in Plattenform hergestellt. Mit ihnen lassen sich im Vergleich zu konventionellen, nichtevakuierten Dämmstoffen deutlich geringere Wandstärken bei gleichem Dämmwert (U-Wert, Wärmedurchgangskoeffizient) erzielen. Die VIPs finden Anwendung sowohl im Gebäudebereich als auch im industriellen Bereich wie etwa für Behälter für den Transport temperaturkritische Stoffe oder als Isolationsmaterial für Warmwasserbehälter.Usually, VIPs are made in sheet form. With them, significantly lower wall thicknesses can be achieved with the same insulation value (U-value, heat transfer coefficient) compared to conventional, non-evacuated insulation materials. The VIPs are used both in the building sector and in the industrial sector, such as containers for transporting temperature-critical substances or as insulation material for hot water tanks.
Allen bekannten VIPs liegt die Problematik zugrunde, Verschmutzungen im Bereich der Siegelnähte durch Rückstände von pulverförmigen Kernmaterial zu vermeiden.All known VIPs is based on the problem of avoiding soiling in the area of the sealed seams by residues of pulverulent core material.
Das VIP besteht üblicherweise aus einem hochporösen Kernmaterial und einer vakuumdichten Hüllfolie bzw. einem Verbund aus unterschiedlichen Hüllfolieschichten. Als Kernmaterial werden hauptsächlich pulver- bzw. faserförmige schüttfähige Materialien verwendet und zu Platten verpresst. Diese Platten werden mit einem Kunststoffvlies ummantelt, um die Staubentwicklung zu unterbinden, die unter Umständen kritisch für die Weiterverarbeitung ist. So muss etwa eine Verschmutzung der Siegelbereiche der Hüllfolie vermieden werden. Die plattenförmigen VIPs lassen sich nach der Herstellung nur begrenzt und mit großem Aufwand umformen und endkonturgerecht anpassen.The VIP usually consists of a highly porous core material and a vacuum-tight jacket film or a composite of different Hüllfoliesayer. As the core material mainly powdered or fibrous pourable materials are used and pressed into plates. These panels are covered with a plastic fleece to prevent the formation of dust, which may be critical for further processing. For example, soiling of the sealing areas of the enveloping foil must be avoided. The plate-shaped VIPs can be after production only limited and with great effort reshape and customize final contour.
Neben der Folienumhüllung und Versiegelung von gepressten Kernen sind auch VIPs zur Schüttung von pulverförmigem Material in einen einseitig offenen Hüllfolienbeutel bekannt. So beschreibt
Mit der vorliegenden Erfindung lässt sich ein VIP aus geschüttetem Kernmaterial herstellen, ohne aufwändig zu gestaltende Einfüllelemente oder randseitig zu verklebende Filtermaterialien anzuwenden. Ebenso kann durch den Einsatz des losen, pulverförmigen Materials inform eines allseitig geschlossenem Kissens anstelle eines verpressten Kernmaterials ein flexibel verformbares VIP hergestellt werden.With the present invention, it is possible to produce a VIP from poured core material without using filling elements that are complicated to design or filter materials to be glued at the edge. Likewise, by using the loose, powdery material inform a cushion closed on all sides instead of a compressed core material, a flexibly deformable VIP can be produced.
Die Erfindung wird wie folgt ausgeführt:
Es wird ein für Luft durchlässiges, für pulverförmiges Material nicht durchlässiges flächig vorliegendes Filtermaterial (
It is an air-permeable, non-permeable for powdery material surface filter material (
Das Filtermaterial ist derart angeordnet, dass sich durch festes Verbinden einer oder mehrerer Filterlagen ein 3-seitig nach Außen abgeschlossener, füllbarer Hohlraum ergibt.The filter material is arranged such that by firmly connecting one or more filter layers results in a 3-sided closed to the outside, fillable cavity.
Der geschaffene Hohlraum wird der gewünschten Menge an pulverförmigen Material (
Der mit pulverförmigen Material gefüllte Hohlraum wird an der offenen Seite derart fest verschlossen, dass sich ein geschlossene Form (Kissen) ergibt, die ein austreten des pulverförmigen Materials nach außen verhindert.The filled with powdery material cavity is closed at the open side so tight that results in a closed shape (cushion), which prevents leakage of the powdery material to the outside.
Das so geschaffene, mit pulverförmigen Material gefüllte luftdurchlässige Kissen wird in den bereitgestellten Beutel aus Hochbarrierefolie eingebracht und unter im Vergleich zum Umgebungsdruck erheblich reduziertem Druck (Vakuum) gesetzt und entlüftet.The thus created, filled with powdery material air-permeable cushion is placed in the provided bag of high barrier film and placed under compared to the ambient pressure considerably reduced pressure (vacuum) and vented.
Unter fortwährendem Vakuum wird die das gefüllte Kissen umgebende Hochbarrierefolie derart fest verschlossen, dass der Verschluss der Hüllfolie (
