Description

  

  Verfahren zur Herstellung von Gebilden, die wenigstens zum Teil  aus     Isolations-Werkstoff    bestehen.    Zur elektrischen     Isolierung    und zur  Wärmeisolierung ist Glimmer als Werkstoff  sehr geschätzt. Es hat jedoch nicht an Ver  suchen gefehlt, den Glimmer für Isolations  zwecke durch andere Werkstoffe zu ersetzen.  Auch hat man bereits gelernt, Erzeugnisse  aus     Glimmerabfällen,    wie beispielsweise     Mi-          kanit,        herzustellen.     



  Nun wurde auch schon versucht, an  Stelle von Glimmer Glas zu verwenden, das  jedoch wegen seiner     Sprödigkeit    und Zer  brechlichkeit, wegen der schlechten     Bearbeit-          barkeit    und anderer Nachteile nur in Aus  nahmefällen als Isoliermaterial Verwendung  finden konnte.  



       Inzwischen    hat man     gelernt,    aus Glas  allerfeinste Fäden     herzustellen    und aus die  sen feinsten Glasfäden Glasgewebe     und    auch  filzartige Gebilde     herzustellen.     



  Es wurde     nun    gefunden, dass die Glas  gewebe oder Glasfilze dadurch wesentlich  verbessert werden können, dass sie vor ihrer    Verwendung imprägniert und unter Druck       verpresst    werden. Die Imprägnierung kann  unter Anwendung von     Wärme        und    mit den     i     verschiedensten Stoffen erfolgen, zum Bei  spiel     mit    Kunstharz, Wasserglas,     Borag-          ,lösungen    und     dergl.        Werden,

      die so     imprä-          gniexten    Glasgewebe oder     Glasfilze        daraufhin     einem hohen Druck ausgesetzt,     gegebenen-          fälle    unter     Erwärmung,    so werden feste     Iso-          lierkörper    mit vorzüglichen Eigenschaften  erhalten. Es gelingt auf diese Weise, Plat  ten, Stäbe, Rohre und Profilstücke der ver  schiedensten Art     herzustellen.    Solche Profil- ;  stücke können zum Beispiel als isolie  rende     gommutatorsegmente    verwendet wer  den.

   Platten aus diesem Isoliermaterial las  sen sich beispielsweise auch stanzen.  



  Ferner wurde gefunden, dass in die gemäss,  vorstehendem hergestellten Isoliermassen mit  Vorteil     Heizdrähte        eingebettet    werden kön  nen. Dazu     finden        insbesondere    solche Mas  sen     Verwendung,    bei denen das Glasgewebe      oder der Glasfilz mit einem anorganischen  Mittel imprägniert wurde.  



  Derartige, Heizdrähte enthaltende Isola  tionen können unter anderem als Heizkörper  für Bügeleisen, als Wärmeplatten, als. heiz  bare Decken- und Wandplatten, für heizbare  Schalen, als     Wärmesteine    und     dergl.    Ver  wendung finden.



  Process for the production of structures which at least partly consist of insulation material. Mica is highly valued as a material for electrical and thermal insulation. However, there has been no lack of attempts to replace the mica with other materials for insulation purposes. One has also already learned to manufacture products from mica waste, such as mikanite.



  Attempts have now been made to use glass instead of mica, but this could only be used as an insulating material in exceptional cases because of its brittleness and fragility, because of its poor machinability and other disadvantages.



       In the meantime, people have learned to make the finest threads out of glass and to use these finest glass threads to make glass fabrics and also felt-like structures.



  It has now been found that the glass fabrics or glass felts can be significantly improved in that they are impregnated and pressed under pressure before they are used. The impregnation can be done with the application of heat and with the most varied of substances, for example with synthetic resin, water glass, Borag, solutions and the like.

      The thus impregnated glass fabrics or glass felts are then subjected to high pressure, possibly with heating, so that solid insulating bodies with excellent properties are obtained. It succeeds in this way, Plat th, rods, pipes and profile pieces of the most varied types of manufacture. Such profile; Pieces can, for example, be used as insulating gommutator segments.

   Plates made from this insulating material can also be punched, for example.



  It has also been found that heating wires can advantageously be embedded in the insulating compounds produced according to the above. For this purpose, in particular those masses are used in which the glass fabric or the glass felt has been impregnated with an inorganic agent.



  Such, heating wires containing Isola functions, among other things, as a heater for iron, as a hot plate, as. Heatable ceiling and wall panels, for heatable bowls, as heat stones and the like.
