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.
