Abstract

Demountable, remountable thermal insulation is intended esp. for nuclear plants and comprises panels or 'cushions' which can be fitted edge to edge to cover a pipe, vessel or the like. The rear face of the cushion adjacent to the plant component is faced with a foil impermeable to dust. This foil is of an elastic, tear-resistant, corrosion-resistant plastics material insensitive to humidity, and is pref. reinforced. The reinforcement may comprise mutually crossing filaments, or a metal or glass, knitted, woven or non-woven fabric or fleece. Filaments may include radiation-resistant plastics filaments, or metal wires. This rear facing foil may optionally also have a further foil laminated onto it, esp. a metal foil. Preferred material for the rear face foil is PTFE. A very thin but nevertheless dustproof rear foil is obtained which does not suffer difficulties in handling and excessively high thermal conductivity.

Description

Die Erfindung bezieht sich auf eine de- und remontierbareThe invention relates to a removable and remountable

Wärmedämmung, insbesondere für nukleare Anlagen, bestehend aus mit ihren Seitenwänden zur Wärmedämmung zusammenbaubaren Kassetten, die an ihrer im Einbauzustand der zu dämmenden Objektwand zugewandten Seite ein mit Wärmedämm-Material gefülltes kissenartiges Gebilde aufweisen, dessen Umhüllung aus einer staubdichten Folie gebildet ist.Thermal insulation, in particular for nuclear installations, consisting of with their side walls for thermal insulation assemblable cassettes, which are attached to their im Installation state of the side facing the object wall to be insulated with thermal insulation material have filled pillow-like structure, the envelope of which is made of a dust-proof Foil is formed.

Eine solche de- und remontierbare Wärmedämmung ist aus der DE-OS 26 23 565 bekannt geworden.Such removable and remountable thermal insulation is from DE-OS 26 23 565 became known.

Bei den dort beschriebenen Kassetten besteht die Umhüllung aus einer Metallfolie. Die Kassetten selbst übernehmen eine ausreichende Abdichtung an den Seitenwänden und gewährleisten außerdem, daß das in der Umhüllung eingeschlossene Wärmedänim-Material beim Einsatz einer solchen Wärmedämmung in nuklearen Anlagen nicht nur nicht verseucht werden kann, sondern auch seinerseits nicht zu weiterer Staubbildung in der die entsprechende Anlage umgebenden Atmosphäre beiträgt.In the case of the cassettes described there, the casing consists of one Metal foil. The cassettes themselves provide a sufficient seal on the Sidewalls and also ensure that what is enclosed in the enclosure Thermal insulation material when using such thermal insulation in nuclear facilities not only cannot be contaminated, but also in turn not to further Contributes to the formation of dust in the atmosphere surrounding the relevant system.

Die Verwendung von Metallfolien als Material für die Umhüllung hat sich durchaus bewährt. Jedoch ist Metall ein guter Wärmeleiter. Diese Eigenschaft von Metall zwingt dazu, die Folien möglichst dünn auszubilden, damit nicht längs der StoD-stellen zwischen den Kassetten ein unerwünscht hoher Wärmedurchgang erfolgt. Der Reduzierung der Dicke der Metallfolien sind jedoch Grenzen gesetzt. Die Herstellung sehr dünner und doch noch ausreichend gegen mechanische Beanspruchungen widerstandsfähige Metallfolien ist möglich, jedoch sehr kostenintensiv. Ferner lassen sich derart dünne Metallfolien nur unter großen Schwierigkeiten verarbeiten. Sie lassen sich z. B. nur schwer miteinander verbinden, z. B. verschweißen.The use of metal foils as the material for the cladding has has proven itself quite well. However, metal is a good conductor of heat. This attribute of metal forces you to make the foils as thin as possible, so not lengthways an undesirably high heat transfer occurs at the butt joints between the cassettes. However, there are limits to the reduction in the thickness of the metal foils. The production very thinner and yet sufficiently resistant to mechanical stresses Metal foils are possible, but very costly. Furthermore, in such a way Process thin metal foils only with great difficulty. You let yourself z. B. difficult to connect with each other, z. B. weld.

Hier setzt die Erfindung ein, die die Aufgaben löst, bei einer im Oberbegriff des Anspruchs 1 angegebenen Kassette die oben im einzelnen dargelegten Nachteile zu vermeiden.This is where the invention comes in, which solves the tasks of an im The preamble of claim 1 specified cassette those set out in detail above Avoid disadvantages.

Die Lösung dieser Aufgabe geschieht durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1.The solution to this problem occurs through the characteristics of the characteristic Part of claim 1.

Bevorzugte Weiterbildungen sind in den Ansprüchen 2 bis 12 angegeben.Preferred developments are given in claims 2 to 12.

Von besonderem Vorteil ist auch, daß die als Umhüllungsmaterial vorgesehenen Kunststoff-Folien wesentlich leichter als Metall-Folien sind.It is also of particular advantage that the provided as wrapping material Plastic foils are much lighter than metal foils.

Die Zeichnung zeigt in einer einzigen Figur einen Schnitt durch zwei aneinander stoßende Kassetten gemäß der Erfindung.The drawing shows a section through two in a single figure butting cartridges according to the invention.

Die Kassette 1 stößt mit ihrer Seitenwand 2 gegen die Seitenwand 3 der Kassette 4. Die Kassette 4 weist ebenso wie die Kassette 1 ein äußeres metallisches Blech 5 auf, das beim wiedergegebenen Ausführungsbeispiel gebogen ist, weil die Kassette beispielsweise einen rohrförmigen Körper teilweise umschließen soll. Bei 6 ist der die Kassettenfüllung darstellende Dämmstoff, z. B. Glas- oder Gesteinswolle angedeutet.The side wall 2 of the cassette 1 hits the side wall 3 of the cassette 4. The cassette 4, like the cassette 1, has a metallic exterior Sheet 5, which is bent in the illustrated embodiment because the Cassette, for example, is intended to partially enclose a tubular body. at 6 is the insulating material representing the cassette filling, e.g. B. glass or rock wool indicated.

7 bedeutet eine Umhüllung aus einer Kunststoff-Folie, die beispielsweise entsprechend armiert sein kann. Die Kunststoff-Folie ist bei 8 mit Hilfe einer eingefalzten Verbindung mit dem metallischen Blech 5 verbunden. Eine andere Ausführungsform der Verbindung ist bei 9 angedeutet. Bei 10 erkennt man ein Blech, das sich über die Verbindungsstelle legt und damit den Außenumfang der Wärmedämmung an den Stoßstellen zwischen den einzelnen Metall kassetten sauber überdeckt und als eine Art Schiebesitz wirkt. Die Verbindung der Umhüllung 7 mit dem metallischem Blech 5 kann auch durch Kleben oder in anderer Weise erfolgen. Die Kanten bei 11 und längs der Seitenwände 2, 3 lassen sich durch Bildung von Quetschfalten o. dgl. sauber ausbilden, gegebenenfalls aber auch durch Schweißverbindung der Ränder entsprechend zugeschnittener Folienbahnen.7 means an envelope made of a plastic film, for example can be armored accordingly. The plastic film is folded in at 8 with the help of a Connection with the metallic sheet 5 connected. Another embodiment of the Connection is indicated at 9. At 10 you can see a sheet that extends over the Connection point and thus the outer circumference of the thermal insulation at the joints neatly covered between the individual metal cassettes and as a kind of sliding seat works. The connection of the casing 7 to the metallic sheet 5 can also be done by Gluing or otherwise done. The edges at 11 and along the side walls 2, 3 can be neatly designed by forming pinch folds or the like, if necessary but also by welding the edges of appropriately cut sheets of film.
