Description

Verfahren zur Metallisierung von Isolierbändern mittels einer Maschine Zusatz zum Patent 475 0,33 Gegenstand des Patents ¢75 033 ist eine Maschine zur Metallisierung der Oberfläche von Filmbändern für die Herstellung von Isolationsfolien für elektrische Kondensatoren durch chemischen Niederschlag des Metalls aus einer Metallsalzlösung, bei der die zu metallisierenden Bänder mittels Trommeln oder Rollen durch Bäder. geführt werden, welche in abwechselnder Reihenfolge die Metallsalzlösung und die Reduzierflüssigkeit enthalten.Process for the metallization of insulating tapes by means of a machine Addendum to patent 475 0.33 The subject of the patent ¢ 75 033 is a machine for metallizing the surface of film tapes for the production of insulating foils for electrical capacitors by chemical precipitation of the metal from a metal salt solution, in which the strips to be metallized by means of drums or rollers through baths. are performed, which contain the metal salt solution and the reducing liquid in alternating order.

Diese Einrichtung hat den Nachteil, daß zu große Mengen der Reduzierflüssigkeit durch das zu metallisierende Band in die Metallsalzlösung übergeführt werden, wodurch die letztere ihre Aktivität rasch verliert.This device has the disadvantage that too large amounts of the reducing liquid be transferred by the band to be metallized into the metal salt solution, whereby the latter quickly loses its activity.

Gegenstand der vorliegenden Erfindung ist nun ein Verfahren zur Metallisierung von Isolierbändern mittels einer Maschine der vorgenannten Art, bei der unter Wegfall des Reduzierbades das Aufbringen der Reduzierflüssigkeit auf das von der Metallsalzlösung benetzte -Band durch Aufspritzen in feinster Verteilung erfolgt und das Band nach dem Aufspritzen der Reduktionsflüssigkeit, aber vor seiner Wiedereinführung in die Metallsalzlösung,-getrocknet oder abgewaschen wird. Als Tragmedium für die aufzuspritzende Reduktionsflüssigkeit dient entweder Preßluft oder Wasserdampf, welchem die Reduktionsflüssigkeit beigemischt ist. Damit von der Reduzierflüssigkeit keine Spuren in die Metallsalzlösung übergeführt werden, kann das nasse Band entweder durch Heißluft getrocknet oder durch Wasser abgewaschen werden. Unter diesen Vorsichtsmaßregeln kann keine Reduktionsflüssigkeit in die Metallsalzlösung eingebracht werden, so daß die letztere bis zum letzten Rest ihre volle Aktivität beibehält.The present invention now relates to a method for metallization of insulating tapes by means of a machine of the aforementioned type, in which the omission of the reducing bath, the application of the reducing liquid to that of the metal salt solution wetted tape is done by spraying on in a very fine distribution and the tape after spraying the reducing liquid, but before reintroducing it into the Metal salt solution, dried or washed off. As a support medium for the to be sprayed on The reducing liquid is either compressed air or water vapor, which the reducing liquid is mixed in. So that there are no traces of the reducing liquid in the metal salt solution transferred, the wet tape can either be dried by hot air or be washed off by water. Under these precautions, no reducing liquid can be introduced into the metal salt solution so that the latter to the last Rest maintains full activity.
