Description

Verwendung von Schaumflocken und/oder Schaumfolien zur Schall-, Wärme- oder elektrischen Isolation Es ist bekannt, Schaumbaustoffe zur elektrischen Isolation sowie zur Schall- und Wärmeisolation zu verwenden. Die bekannten Schaumbaustoffe haben sich im allgemeinen für die genannten Zwecke gut bewährt, besitzen jedoch häufig keine genügende Festigkeit. Außerdem ist es bei den bekannten Schaumbaustoffen nicht möglich, den Luftgehalt beliebig zu steigern.Use of foam flakes and / or foam sheets for sound, heat or electrical insulation. It is known that foam building materials are used for electrical insulation as well as to be used for sound and heat insulation. The well-known foam building materials have generally proven themselves well for the purposes mentioned, but have often insufficient strength. It is also the case with the well-known foam building materials not possible to increase the air content at will.

Zur Erhöhung der Festigkeit und des Luftgehaltes von Schaumbaustoffen wurde vorgeschbagen, den Baustoffen vor ihrer Verfestigung einzelne verfestigte Schaumflocken oder Schaumfolien als Füllmittel zuzusetzen. Es wurde nun gefunden, d:aß die verfestigten einzelnen Schaumflocken bzw. Schaumfolien auch in gasförmigen oder flüssigen Medien verwendet werden können. Zum Beispiel kann der sonst mit einem Schaumbiaustoff oder Kork o& dgl. ausgefüllte Raum von Kühlschränken mit einzelnen Schaumflocken gefüllt werden. Die Anwendung von Schaumfolien hat besonderes Interesse z. B. bei den ölkabeln und dien Kabeln, die zur Fortleitung hochfrequenter Wechselströme dienen. Erfindungsgemäß wird um den Kern eine Schaumfolie gewickelt, die nach dem Einlegen des Kabels in C51 eine ausgezeichnete Isolation. bewirkt. Auch zum Füllen von Vergußmassen für elektrische Maschinen und Apparate können die verfestigten Schaumflocken bzw. Schaumfolien mit Vorteil verwendet werden.To increase the strength and air content of foam building materials It was suggested that the building materials should be solidified before they solidified Add foam flakes or foam sheets as fillers. It has now been found d: ate the solidified individual foam flakes or foam sheets also in gaseous form or liquid media can be used. For example, he can usually talk to you Foam or cork or the like filled space of refrigerators with individual Foam flakes are filled. The use of foam films is of particular interest z. B. in the case of oil cables and cables that carry high-frequency alternating currents to serve. According to the invention, a foam film is wrapped around the core, which after Insertion of the cable in C51 provides excellent insulation. causes. Even to the The solidified can be filled with casting compounds for electrical machines and apparatus Foam flakes or foam sheets can be used with advantage.
