Description
Wärmeisolierung, insbesondere für Rohrleitung Die Erfindung bezieht sich auf wenigstens zum Teil aus Fasermaterial bestehende Wärmeisolierungen, insbesondere für Rohrleitungen, die honen Temperaturen standhalten können.Thermal insulation, particularly for piping The invention relates based on at least partially made of fiber material thermal insulation, in particular for pipelines that can withstand honing temperatures.
Um eine wirksame Wärmeisolation zu erzielen, muß die Dichte- der Isolierhülle in einem bestimmten Verhältnis zur Temperatur stehen, d. h. je höher die Temperatur ist, desto größer muß die Dichte der Isolierung sein. Eine Erhöhung der Dichte bedingt aber gewölinli@ch und unvermeidlich die Verwendung von kurzfaserigem oder nichtfaserigem Material, ,velches sich genügend dicht schichten läßt. Eine ganz aus solchem Material hergestellte Isolierhülle ist daher nicht nur schwer, sondern auch sehr brüchig. Die Erfindung hat den Zweck, eine Isolierhülle für hohe Temperaturen zu schaffen, die .diese Nachteile nicht besitzt.In order to achieve effective thermal insulation, the density of the insulating cover are related to the temperature, d. H. the higher the temperature the greater the density of the insulation must be. Requires an increase in density but wölinli @ ch and inevitably the use of short fiber or non-fiber Material,, velches can be layered sufficiently densely. One made entirely of such material The insulating sheath produced is therefore not only heavy, but also very brittle. The invention has the purpose of creating an insulating cover for high temperatures, which does not have these disadvantages.
Die Erfindung besteht dm wesentlichen darin, daß die Isolierung im Querschnitt verschiedene Dichten aufweist, indem sie aus einem inneren Teil großer Dichte aus kurzen Fasern oder nichtfaserigem Material und einem äußeren Teil geringer Dichte aus längeren Fasern hergestellt .ist.The invention consists essentially in the fact that the insulation in Cross-section has different densities by being made up of an inner part large Density of short fibers or non-fibrous material and an outer part lower Density is made from longer fibers.
Eine solche gegen hohe Temperaturen beständige Isolierung für Rohrleitungen läßt sich auf verschiedene Weise herstellen. Gemäß einerA.usführungwird Mineralwolle oder ein Material, wie aufgespaltener Glimmer, m,it einem hitzebeständigen Bindemittel, wie Natriumsilikat oder Kalkkitt, in dünnen Lagen um einen Kern gelegt, bis eine Masse solcher Stärke und Dichte entsteht, @daß für durchtretende Wärme das gewünschte Temperaturgefälle eintritt. Um diese Schicht wird eine äußere, nicht brüchige Masse aus Glasfasern geeigneter Länge, die,durch Stärke gebunden sind, in geeigneter Dicke angebracht. Die Stärke der inneren Masse wird derart bemessen, daß die durch sie hindurchtretende Wärme keinen schädlichen Einfluß auf den Zusammenhalt der äußeren Masse 'hat. Nach Fertigstellung -der so gebildeten Isolierhülle wird diese in gewünschte Teile aufgeteilt, um sie auf Rohren anbringen zu können.Such a high temperature resistant insulation for pipelines can be made in different ways. According to one embodiment, mineral wool is used or a material such as split mica, with a heat-resistant binder, like sodium silicate or lime putty, in thin layers around a core laid until a mass of such strength and density arises, @ that for penetrating Heat the desired temperature gradient occurs. Around this layer is an outer, non-fragile mass of glass fibers of suitable length bound by starch are attached in a suitable thickness. The strength of the internal mass is measured in such a way that that the heat passing through them has no detrimental effect on cohesion of the external mass'. After completion - the insulating cover formed in this way is these divided into desired parts in order to be able to attach them to pipes.
Nach einer anderen A usfüh.rung kann auch die Masse zusammenhaftender Glasfasern um einen Kern gewickelt «-erden, der einen größeren Durchmesser als,der im ersten Beispiel benutzte hat. Die auf diesem Kern gehi:ldete Hülle wird dann in zwei oder mehr Teile aufgeschlitzt. Auf die Innenseite dieser Teile wird als,dannidas andere Material durch Aufspritzen oder sonst-wie aufgebracht. So lange dieses Material noch formbar ist, werden die Teile auf einen Kern vom Durchmesser .des zu isolierenden Rohres aufgesetzt und auf diesem gelassen, bis auch die so gebildete Innenschicht sich verfestigt hat.According to another embodiment, the mass can also be more cohesive Glass fibers wrapped around a core, which is larger in diameter than that used in the first example. The shell held on this core then becomes slit in two or more parts. The inside of these parts is called, dannidas other material applied by spraying or otherwise. As long as this material is still malleable, the parts are placed on a core with the diameter of the .des to be isolated Put the tube on and leave it on until the inner layer formed in this way has solidified.
