Description

Verfahren zur Erhöhung der Haftfähigkeit der Lackisolation auf Drähten aus Widerstandsmaterial. In der Schwachstromtechnik ist man allgemein bestrebt, besonders bei dünnen Drähten, statt der teueren Isolierung mittels Seide oder Baumwolle den billigeren Lacküberzug zu verwenden. Die Lackisolierung ermöglicht überdies eine bessere Ausnutzung des Wikkelraumes. Es ist bereits gelungen, Kupferdrähte bis zu den kleinsten Durchmessern mit Lack zu isolieren. Dagegen ist man bei der Isolierung von Drähten aus Widerstandsmaterial noch heute auf die Umspinnung mit Seide, Baumwolle u. dgl. angewiesen, weil auf solchen Drähten, besonders wenn sie aus nickelhaltigen Legierungen bestehen, der Lack schlecht haftet. Die Lackschicht springt in der Regel bei der Verarbeitung ab. Man hat versucht, ein besseres Haften des Lacküberzuges dadurch herbeizuführen, daß man aus der Drahtoberfläche einzelne Teilchen auf chemischem oder mechanischem Wege entfernte und dadurch die Oberfläche aufrauhte. Dies scheiterte jedoch meistens an dem schwachen Querschnitt derartiger Drähte.Process for increasing the adhesion of the enamel insulation to wires made of resistance material. In low-voltage technology, one generally strives to especially with thin wires, instead of expensive insulation using silk or cotton to use the cheaper varnish coating. The lacquer insulation also enables better utilization of the winding space. It has already succeeded in making copper wires to insulate down to the smallest diameters with varnish. On the other hand, one is with the Insulation of wires made of resistance material still today on the wrapping with Silk, cotton and the like, because on such wires, especially when they consist of alloys containing nickel, the paint does not adhere well. The paint layer usually jumps off during processing. They tried to get a better grip to bring about the lacquer coating that one from the wire surface individual Particles removed chemically or mechanically and thereby the surface roughened. However, this mostly failed due to the weak cross-section of such Wires.

Nach der Erfindung wird ein besseres Haften des Lacküberzuges durch eine besondere Behandlung des Drahtes vor dem Lackieren erzielt. Bei dieser Behandlung wird der Draht mit einen den Lack bindenden Überzug aus Metall versehen. Es wird also nicht, wie bei dem bekannten Aufrauhen der Drahtoberfläche, der Querschnitt des Drahtes geschwächt, sondern verstärkt. Man kann deswegen auch die schwächsten Drähte dieser Behandlung aussetzen, ohne daß däbei der Draht an mechanischer Festigkeit verliert.According to the invention, a better adhesion of the lacquer coating is achieved a special treatment of the wire is achieved before painting. In this treatment the wire is provided with a metal coating that binds the lacquer. It will so not the cross-section, as is the case with the well-known roughening of the wire surface of the wire weakened, but reinforced. You can therefore also use the weakest Expose wires to this treatment without the wire losing mechanical strength loses.

Die Herstellung des Überzuges erfolgt am zweckmäßigsten auf galvanischem Wege. Sie kann auf zweierlei Weise vorgenommen werden. Entweder wird die Drahtoberfläche vollständig mit einer Metallhaut überzogen, oder es wird nur an einzelnen Punkten der Ober-Räche Metall angelagert, so daß ein netzardger Überzug entsteht. Während im ersten Fall der Überzug aus einem Metall bestehen muß,, auf dem Lack hafte, beispielsweise Kupfer, Silber, Gold, kann man im zweiten Fall auch Metall verwenden, auf dem Lack an sich nicht haftet, beispielsweise -Nickel, da die Lackschicht von dein Unebenheiten der Oberfläche festgehalten wird.The production of the coating is most expediently carried out by electroplating Ways. It can be done in two ways. Either the wire surface will completely covered with a metal skin, or it is only at individual points Metal is deposited on the surface, so that a net-like coating is created. While in the first case the coating must consist of a metal, adhere to the paint, for example Copper, silver, gold, in the second case you can also use metal on the paint does not adhere to itself, for example -Nickel, because the varnish layer of your bumps the surface is held.

Einen galvanischen Niederschlag der zweiten Art erhält man bekanntlich, wenn man die Stromdichte oder die Niederschlagsdauer oder beide entsprechend klein wählt. Beispielsweise kann man den Draht rasch durch ein galvanisches Bad hindurchführen, so daß die einzelnen Drahtteile nacheinander das Bad durchlaufen.A galvanic deposit of the second type is known to be obtained if one considers the current density or the precipitation duration or both correspondingly small chooses. For example, you can quickly run the wire through an electroplating bath, so that the individual wire parts pass through the bath one after the other.

Nach der galvanischen Behandlung wird die Badeflüssigkeit abgewaschen, der Draht getrocknet und hierauf lackiert.After the galvanic treatment, the bath liquid is washed off, the wire dried and then varnished.

Der metallische Überzug kann auch mittels Amalgam oder Glanzmetall erzeugt werden.The metallic coating can also by means of amalgam or bright metal can be produced.
