Description

Abänderung des Verfahrens zum Isolieren von Massekernen, insbesondere für Fernmeldeleitungen Das Hauptpatent betrifft ein Verfahren zur Isolation von Massekernen, insbesondere für Fernmeldeleitungen, die durch Pressen der magnetisierbaren Teilchen, die mit einer Überzugsschicht versehen sind, hergestellt sind, und zwar soll für den isolierenden Überzug nach dem Hauptpatent Wasserglas und Zucker verwendet werden.Modification of the method for isolating mass cores, in particular for telecommunication lines The main patent relates to a method for the isolation of Ground cores, especially for telecommunication lines, which are produced by pressing the magnetizable Particles provided with a coating layer are produced, namely should be used for the insulating coating according to the main patent water glass and sugar will.

Nach der vorliegenden Erfindung wird eine Abänderung des Verfahrens zum Isolieren von Massekernen nach dem Hauptpatent dadurch bewirkt, daß neben dem Zucker an Stelle des Wasserglases Kieselsäuregel, allerfeinstes Kaolin, Talkum, Schwerspat, Zement, Aluminiumtrioxyd oder ähnliche Füllstoffe verwendet werden. Die Erfindung geht dabei von der neuen und durchaus nicht vorauszusehenden Erkenntnis aus, daß ohne Beeinträchtigung der mechanischen und magnetischen Eigenschaften der Massekerne, zum Teil sogar mit besserem Erfolg, das Wasserglas im Verfahren des Hauptpatents durch andere Füllstoffe ersetzt werden kann.According to the present invention, a modification of the method for the isolation of mass cores according to the main patent in that in addition to the Sugar instead of water glass, silica gel, the finest kaolin, talc, Barite, cement, aluminum trioxide or similar fillers can be used. The invention is based on the new and by no means foreseeable knowledge from that without impairing the mechanical and magnetic properties of the Mass cores, sometimes even with better success, the water glass in the process of Main patent can be replaced by other fillers.

Während nämlich-einjIsolation, @velche lediglich aus einer Zuckerlösung besteht, noch beträchtliche Nachwirkungsverluste an den fertigen Spulen ergibt, wurde festgestellt, daß die höheren Nachwirkungsverluste vermieden werden können, wenn neben der Zuckerlösung ein Füllmittel bei der Massekernisolation verwendet wird. Wird beispielsweise bei einer reinen Zuckerisolation ein Wirbelstromverlust pro Henry von weniger als zwei Ohm für den fertigen Massekem erzielt, so treten Nachwirkungsverluste pro Henry von etwa io bis 12 Ohm auf. Wird die Zuckermenge zum Teil durch ein Füllmittel ersetzt, so kann man erreichen, daß der Nachwirkungsverlust unter 5 Ohm pro Henry sinkt.During namely-einjIsolation, @velche only from a sugar solution exists, there are still considerable after-effects losses on the finished coils, it was found that the higher after-effects losses can be avoided, if a filler is used in the earth core insulation in addition to the sugar solution will. For example, there is an eddy current loss in the case of pure sugar insulation achieved less than two ohms per henry for the finished mass core, so step After-effects losses per henry of about 10 to 12 ohms. Will the amount of sugar partially replaced by a filler, it can be achieved that the loss of after-effects drops below 5 ohms per henry.

Als Füllmittel haben sich sowohl wasserlösliche Salze als auch unlösliche Festsubstanzen, die genügend fein zerkleinert sind, geeignet erwiesen. Werden Festsubstanzen als Füllstoffe benutzt, so wird zweckmäßig der Teilchendurchmesser um eine Zehnerpotenz oder mehr kleiner als der Durchmesser der magnetisierbaren Teilchen gewählt. Besonders gute Erfolge wurden erzielt, wenn die Mengen an Füllstoff und Zucker gleich genommen wurden. Vorzugsweise beträgt die Menge an Zucker und Füllstoff je etwa o,75 bis 3°/o des Kerngewichtes.Both water-soluble salts and insoluble salts have proven to be used as fillers Solid substances that are sufficiently finely crushed have been shown to be suitable. Are solids Used as fillers, the particle diameter is expediently around a power of ten or more smaller than the diameter of the magnetizable particles. Particularly Good results have been obtained when the amounts of filler and sugar are taken alike became. Preferably the amount of sugar and filler is about 0.75 to 3 ° / o of the core weight.
