- the extrusion of the bar is carried out by co-extruding highly adhesive copolymeric polyolefin and normal polyolefin.
- highly adhesive copolymeric polyolefin and normal polyolefin are advantageously used, as a result of which the cathode sheet metal according to the invention is produced becomes cheaper.
- the heat required for the extrusion is optimally used.

- cathode sheets in such a way that a layer of adhesive copolymeric polyolefin is arranged on the surfaces to be insulated and a part of ordinary polyolefin, which makes up the last body in its essential volume, is pushed onto this layer.
- copolymeric polyolefins are copolymers of olefin and adhesive additives for metal surfaces.
- These adhesive additives are usually aliphatic carboxylic acids in an amount of 1 to 10%, for example acrylic acid or its derivatives.
- esters such as. B. vinyl acetates may be present.

Abstract
Description
Die Erfindung bezieht sich auf ein Kathodenblech für die elektrolytische Gewinnung von Zink, mit einer Platte aus Aluminium und einer auf mindestens einem Rand der Platte diesen umgebend aufgeschmolzenen Isolationsleiste aus Kunststoff.The invention relates to a cathode sheet for the electrolytic production of zinc, with a plate made of aluminum and an insulating strip made of plastic melted on at least one edge of the plate surrounding it.
Bei heute bekannten Kathodenblechen für die elektrolytische Gewinnung von Zink sind an den Rändern Isolierungsleisten angeordnet. Dies ist deswegen notwendig, um das an den Kathodenflächen abgeschiedene Zink daran zu hindern, in Richtung der Anodenplatte bzw. Elektrolytwanne zu wachsen und dadurch einen Kurzschluß zu erzeugen. Diese Isolierungsleisten sind entweder an den Rändern des Kathodenblechs aufgeschnappt oder aufgepreßt. Es sind aber auch Versionen mit angeschraubten Isolationsleisten bekannt. Diese Isolationsleisten selbst bestehen aus Kunststoff, Gummi oder Holz. Ein Kathodenblech der eingangs genannten Art ist aus DE-A-3 219 300 bekannt.In today's known cathode sheets for the electrolytic production of zinc, insulating strips are arranged at the edges. This is necessary in order to prevent the zinc deposited on the cathode surfaces from growing in the direction of the anode plate or electrolyte trough and thereby producing a short circuit. These insulation strips are either snapped onto the edges of the cathode sheet or pressed on. Versions with screwed insulation strips are also known. These insulation strips themselves are made of plastic, rubber or wood. A cathode plate of the type mentioned is known from DE-A-3 219 300.
Da die Kathodenbleche im Betrieb mit Schwefelsäure, die als Elektrolyt verwendet wird, getaucht sind, kommt es zur Korrosion des Aluminiums. Diese Korrosion tritt bevorzugt unter den Leisten auf. Dies deshalb, da die Säure zwischen den Blechen und den Isolationsleisten eindringt und dort ein sehr schnelles Korrodieren des Aluminiums bewirkt. Es erfolgt somit ein frühzeitiger Ausfall des Kathodenblechs, da die Ränder ausfressen, die Leiste an Halt am Blech verliert und somit es zu einem Kurzschluß beim Wegbrechen der Isolationsleiste zwischen anwachsendem Zink und der Anodenplatte bzw. Elektrolytwanne kommt.Since the cathode sheets are immersed in sulfuric acid, which is used as the electrolyte, the aluminum corrodes. This corrosion occurs preferentially under the strips. This is because the acid penetrates between the sheets and the insulation strips and causes the aluminum to corrode very quickly. There is therefore an early failure of the cathode sheet, since the edges erode, the strip loses its grip on the sheet and thus there is a short circuit when the insulation strip between the growing zinc and the anode plate or electrolyte tray breaks away.
Dieser ungünstige Effekt dieser Korrosion wird erfindungsgemäß dadurch verhindert, daß die Isolationsleisten aus copolymerem Polyolefin bestehen, welche um die Kanten, die die Schmalseitenflächen mit den Elektrodenflächen bilden, aufgeschmolzen sind.This adverse effect of this corrosion is invented thereby preventing the insulation strips from being made of copolymeric polyolefin, which are melted around the edges which form the narrow side surfaces with the electrode surfaces.
Die Paarung copolymeres Polyolefin/Aluminium erweist sich dabei als besonders flüssigkeitsdicht gegenüber dem aggressiven schwefelsaueren Elektrolyten.The combination of copolymeric polyolefin / aluminum proves to be particularly liquid-tight against the aggressive sulfuric acid electrolyte.
Gemäß einer bevorzugten Ausgestaltung der Erfindung umfaßt die Isolationsleiste blechseitig eine Lage aus dem copolymeren Polyolefin und im übrigen besteht sie aus gewöhnlichem Polyolefin. Diese Bauweise ist sehr preisgünstig, weil weniger von dem teueren copolymeren Polyolefin notwendig ist.According to a preferred embodiment of the invention, the insulation strip on the sheet metal side comprises a layer of the copolymeric polyolefin and, moreover, it consists of ordinary polyolefin. This design is very inexpensive because less of the expensive copolymeric polyolefin is required.
Es ist weiters in einer Ausgestaltung der Erfindung eine solche Bauweise vorgesehen, daß die Isolationsleiste insgesamt aus dem hochhaftenden Polyolefin besteht.It is further provided in one embodiment of the invention such a construction that the insulation strip consists entirely of the highly adhesive polyolefin.
Bei dieser Bauweise kann bei großen Stückzahlen herzustellender Bleche besonders kostengünstig, weil einfach, gefertigt werden.With this construction method, sheet metal to be produced in large quantities can be manufactured particularly cost-effectively because it is simple.
Es hat sich gezeigt, daß das dazu verwendende Herstellungsverfahren erfindungsgemäß so durchgeführt wird, daß die Isolationsleiste extrudiert wird und nach der Extrusion an den anzuhaftenden Flächen des Kathodenblechbandes in der Wärme (bei Temperaturen zwischen 100 und 200 °C, vorzugsweise 160 und 180 °C, für 1 bis 5 min) angedrückt wird, die Bleche zugeschnitten und danach Halterungen an den Schmalseitenflächen des Kathodenblechs angeschweißt werden, die die mit einer Isolationsleiste versehenen Schmalseitenflächen verbinden.It has been shown that the manufacturing process used for this purpose is carried out according to the invention in such a way that the insulation strip is extruded and after the extrusion on the surfaces to be adhered to the cathode sheet metal strip in the heat (at temperatures between 100 and 200 ° C., preferably 160 and 180 ° C. for 1 to 5 min), the sheets are cut to size and then brackets are welded to the narrow side surfaces of the cathode sheet, which connect the narrow side surfaces provided with an insulation strip.
Es ist dabei in einer weiteren Ausgestaltung der Erfindung günstig, daß die Extrusion der Leiste durch Koextrusion von hochhaftendem copolymerem Polyolefin und normalem Polyolefin erfolgt. Dadurch wird weniger von dem teueren und nur blechseitig erforderlichen hochhaftenden Polyolefin verwendet, wodurch die Herstellung des erfindungsgemäßen Kathodenblechs günstiger wird.It is advantageous in a further embodiment of the invention that the extrusion of the bar is carried out by co-extruding highly adhesive copolymeric polyolefin and normal polyolefin. As a result, less of the expensive high-adhesion polyolefin, which is only required on the sheet metal side, is used, as a result of which the cathode sheet metal according to the invention is produced becomes cheaper.
Durch die Extrusion des Profils mit nachfolgendem Aufschmelzen auf den Kathodenblechbändern wird die für die Extrusion notwendige Wärme optimal genützt. Die Produktion kann kontinuierlich erfolgen, wodurch große Mengen an solchen Kathodenblechbändern hergestellt werden können. Diese sind nachher nur mehr zu schneiden und an ihnen die für die Stromeinleitung und Aufhängung benötigten Halterungen anzuordnen.By extruding the profile with subsequent melting on the cathode sheet metal strips, the heat required for the extrusion is optimally used. The production can take place continuously, whereby large quantities of such cathode sheet metal strips can be produced. Afterwards, these can only be cut and the brackets required for the current introduction and suspension arranged on them.
Es ist in einer Ausgestaltung der Erfindung günstig, Kathodenbleche so herzustellen, daß eine Schicht aus haftendem copolymerem Polyolefin auf den zu isolierenden Flächen angeordnet wird und auf diese Schicht ein Teil aus gewöhnlichem Polyolefin, der den Leistenkörper in seinem wesentlichen Volumen ausmacht, aufgeschoben wird.It is advantageous in one embodiment of the invention to produce cathode sheets in such a way that a layer of adhesive copolymeric polyolefin is arranged on the surfaces to be insulated and a part of ordinary polyolefin, which makes up the last body in its essential volume, is pushed onto this layer.
Dadurch, daß dieses gut haftende Polyolefin dicht mit dem Kathodenblech verbunden ist, kann kein Elektrolyt in die Verbindung eindringen und die eigentliche Isolationsleiste braucht lediglich warm aufgeschoben zu werden. Die Haftung, die zwischen der Schicht Polyolefin und der übrigen Isolationsleiste vorhanden ist, reicht beim Betrieb des Kathodenblechs zur Befestigung aus. Dieses Verfahren ist besonders dann wirtschaftlich, wenn nur wenige Kathodenbleche erzeugt werden sollen, was bei Reparaturen und bei der Wartung einer Elektrolyseanlage häufig der Fall ist.Because this well-adhering polyolefin is tightly connected to the cathode sheet, no electrolyte can penetrate the connection and the actual insulation strip only needs to be pushed on warm. The adhesion that exists between the polyolefin layer and the rest of the insulation strip is sufficient for fastening when the cathode sheet is in operation. This process is particularly economical if only a few cathode sheets are to be produced, which is often the case for repairs and for the maintenance of an electrolysis system.
Copolymere Polyolefine im Sinne der Erfindung sind Mischpolymerisate von Olefin und Haftzusätzen für Metalloberflächen. Diese Haftzusätze sind in der Regel aliphatische Carbonsäuren in einer Menge von 1 bis 10 %, beispielsweise Acrylsäure oder deren Derivate. Statt der Acrylsäure können auch Ester wie z. B. Vinylacetate vorhanden sein. Vinylacetat kann auch gleichzeitig mit Acrylsäure vorhanden sein, ebenso kommen auch andere Terpolymere in Frage. Geeignet sind letzlich diejenigen Schmelzkleber auf Polyolefinbasis, bei welchen eine ausreichende Korrosionsbeständigkeit gewährleistet ist.For the purposes of the invention, copolymeric polyolefins are copolymers of olefin and adhesive additives for metal surfaces. These adhesive additives are usually aliphatic carboxylic acids in an amount of 1 to 10%, for example acrylic acid or its derivatives. Instead of acrylic acid, esters such as. B. vinyl acetates may be present. Vinyl acetate can also be present at the same time as acrylic acid, as are other terpolymers. Ultimately, those hot melt adhesives based on polyolefin are suitable which have sufficient corrosion resistance is guaranteed.
