Description

Die Erfindung betrifft einen kathodischen Korrosionsschutz von mindestens einem Auftragselement bei Papierstreichanlagen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a cathodic protection against corrosion according to at least one order element for paper coating systems the preamble of claim 1.

Es sind Papierstreichanlagen zum Betreichen von vorbeifahrenden Papierbahnen mittels eines Streichrakels aus der DE 39 31 793 A1 vorbekannt. Dabei wird auf eine Papierbahn mittels einer Dosiervorrichtung eine Streichmasse aufgetragen, die durch ein nachfolgendes elastisches Streichrakel gleichmäßig dünn auf die Papieroberfläche gestrichen wird. Derartige Streichrakel bestehen in der Praxis meist aus Eisen oder einer Eisenlegierung und unterliegen einer abrasiven- und korrosiven Abnutzung. Da derartige Streichanlagen von Papiermaschinen kontinuierlich in Betrieb sind, bedeutet eine Abschaltung zum Wechsel abgenutzter Rakel oder anderer Auftragselemente einen erheblichen Produktionsausfall und größere Mengen von Ausschußpapier beim Wiederanlauf einer derartigen Papiermaschine. Es ist deshalb stets ein Ziel bei derartigen Streichanlagen, die Standzeit der Auftragselemente wie die Streichrakel und dergleichen zu erhöhen. So wurden schon Streichrakel entwickelt, die mit einer keramischen Beschichtung versehen sind, wodurch die Standzeit erheblich verlängert wurde. Diese Streichrakel sind aber nicht elastisch und auch erheblich aufwendiger in der Herstellung. They are paper coating systems for painting passing vehicles Paper webs by means of a doctor blade from DE 39 31 793 A1 previously known. It is on a paper web by means of a Dosing device applied a coating slip by a subsequent elastic doctor blade evenly thin is painted on the paper surface. Such squeegees in practice mostly consist of iron or an iron alloy and are subject to abrasive and corrosive wear. Because such coating systems of paper machines continuously are in operation means switching off for a change worn squeegee or other application elements a considerable Loss of production and larger quantities of reject paper when restarting such a paper machine. That is why Always a goal with such coating systems, the service life the application elements such as the doctor blade and the like to increase. So squeegees have been developed that with are provided with a ceramic coating, whereby the Service life was significantly extended. These are squeegees but not elastic and also considerably more complex in the Production.

Der Erfindung liegt deshalb die Aufgabe zugrunde, Streichanlagen mit einfachen Auftragselementen so zu verbessern, daß sich die Standzeit der Auftragselemente erhöht.The invention is therefore based on the object, coating systems to improve with simple order elements so that the service life of the order elements increases.

Diese Aufgabe wird durch die im Patentanspruchs 1 angegebene Erfindung gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Die Erfindung hat den Vorteil, daß insbesondere der korrosionsbedingte Verschleiß an den Auftragselementen insbesondere den Streichrakeln und Egalisierungsstäben weitgehend vermieden wird, so daß längere Wechselintervalle möglich sind, ohne werkstoffmäßige Veränderungen an den Rakel bzw. den Egalisierungsstäben vorzunehmen.This object is achieved by the one specified in claim 1 Invention solved. Developments of the invention are in the Subclaims specified. The invention has the advantage that especially the corrosion-related wear on the application elements especially the doctor blades and leveling sticks is largely avoided, so that longer change intervals are possible without material changes to carry out the squeegee or leveling bars.

Bei einer besonderen Ausführungsart ist zusätzlich eine externe Spannungsquelle vorgesehen, durch die der Korrosionsschutz erheblich verbesserbar ist und durch die gleichzeitig die elektrokinetischen Kräfte der Streichmasse aktivierbar sind, wodurch gleichzeitig der Strich verbessert und die Bartbildung der Streichmasse an den Streichrakeln verringert wurde.In the case of a special embodiment, there is also an external one Voltage source provided by the corrosion protection is significantly improved and through which at the same time electrokinetic forces of the coating slip can be activated, which improves the stroke and the beard formation at the same time the coating mass on the doctor blades was reduced.

Die Erfindung wird anhand eines Ausführungsbeispiels, das in der Zeichnung dargestellt ist, näher erläutert. Die Zeichnung zeigt eine Streichanlage für Papierbahnen 11 mit externer Spannungsquelle 6 und einer Opferanode 3, die in der Streichmasse 4 angeordnet ist. Die Streichanlage besteht aus einer Verteilungsröhre 5, die auf der gesamten Länge quer zur laufenden Papierbahn 11 verläuft. Diese Verteilungsröhre 5 steht mit einem nicht dargestellten Vorratsbehälter für die Streichmasse in Verbindung, der ständig Streichmasse in die Verteilungsröhre 5 befördert. Dadurch tritt die Streichmasse 4 aus dem oberen Auslaufschlitz der Verteilungsröhre 5 aus und wird von der vorbeilaufenden Papierbahn 11 mitgenommen, die von einer Gegenwalze 1 an den Schlitz vorbeigeführt wird. The invention is based on an embodiment that in the drawing is shown, explained in more detail. The drawing shows a coating system for paper webs 11 with external Voltage source 6 and a sacrificial anode 3 in the coating slip 4 is arranged. The coating system consists of a Distribution tube 5, which is transverse to the entire length Paper web 11 runs. This distribution tube 5 stands with a storage container, not shown, for the coating slip in connection, the constant coating mass in the distribution tube 5 promoted. As a result, the coating slip 4 emerges from the upper outlet slot of the distribution tube 5 taken along by the passing paper web 11, which by a counter roller 1 is guided past the slot.

Die überschüssige Streichmasse 4 wird von einem Auftragselement, das als kammartige Dosierlamelle 9 ausgebildet ist, wieder von der Papierbahn 11 abgestreift und gelangt in einen Auffangbehälter 2, von dem aus die Streichmasse 4 wieder in den Vorratsbehälter zurückgefördert wird. Die von der Dosierlamelle 9 aufgetragenen Beschichtungsmittelfäden oder -stränge werden von dem nachfolgenden weiteren Auftragselement, das als Streichrakel 10 ausgebildet ist, gleichmäßig dünn auf die Papierbahn gestrichen, indem das Streichrakel 10 unter einem spitzen Winkel gleichmäßig unter einem bestimmten Druck sich auf der Gegenwalze 1 abstützt. Dabei handelt es sich um ein elastisches Rakel 10, das sich s-förmig durchbiegt und das quer zur gesamten Papierbahn 11 auf der Gegenwalze 1 aufliegt, so daß ein möglichst gleichmäßiger dünner Strich auf der Papieroberfläche 11 aufgetragen wird. Durch diese Vorrichtung wird eine Papierseite mit einem Strich versehen. Es sind aber auch Streichanlagen zum beidseitigen Bestreichen auch mit mehreren Strichen mittels mehrerer hintereinander angeordneter Auftragselemente ausführbar. Dabei müssen nicht unbedingt Streichrakel 10 vorgesehen sein, sondern als Auftragselemente können auch Auftragswalzen mit Egalisierungsstäben und vergleichbare Auftragswalzen eingesetzt werden.The excess coating slip 4 is from an application element, which is designed as a comb-like metering lamella 9 again stripped from the paper web 11 and gets into one Collection container 2, from which the coating slip 4 is in again the reservoir is returned. The one from the metering lamella 9 applied coating agent threads or strands are followed by the further order element that follows as Doctor blade 10 is formed, evenly thin on the paper web deleted by the doctor blade 10 under a acute angles evenly under a certain pressure is supported on the counter roller 1. This is a elastic squeegee 10 that bends in an S-shape and that lies across the entire paper web 11 on the counter roller 1, so that a thin, even line as possible on the paper surface 11 is applied. Through this device a line is applied to one side of the paper. But there are also coating systems for coating on both sides with several strokes by means of several one behind the other Order elements can be executed. You don't necessarily have to Doctor blade 10 may be provided, but as application elements can also apply rollers with leveling bars and comparable Application rollers are used.

Die Opferanode 3 ist in der Verteilungsröhre 5 angeordnet und dort von der Streichmasse 4 umgeben, wobei sie mit dieser in elektrischem Kontakt steht. Dabei stellt die Streichmasse als wäßrige anionische Dispersion einen Elektrolyten dar, der in Verbindung mit zwei gegensätzlichen Elektroden ein Spannungselement bildet. Die Opferanode 3 als eine der gegensätzlichen Elektroden ist aus einem elektrisch leitfähigen Werkstoff, der in der Spannungsreihe unedler ist als das Material der Auftragselemente 9, 10, die als Kathode geschaltet sind. Hierdurch wird das elektrische Element gebildet, das nur an dem unedleren Material einen korrosiven Materialabtrag bewirkt. Vorteilhafterweise wird deshalb eine Opferanode 3 aus Zink verwendet, da dieses Material gegenüber dem Streichrakel 10 bzw. der Egalisierungsstäbe das unedlere Material darstellt, weil diese in der Praxis meist aus Eisen oder einer Eisenlegierung gefertigt werden und damit der Korrosion unterworfen sind.The sacrificial anode 3 is arranged in the distribution tube 5 and there surrounded by the coating slip 4, with it in this electrical contact. The coating slip represents aqueous anionic dispersion is an electrolyte which in Connection with two opposite electrodes is a voltage element forms. The sacrificial anode 3 as one of the opposite Is made of an electrically conductive material that in the voltage series is less noble than the material of the order elements 9, 10, which are connected as a cathode. hereby the electrical element is formed, which is only on the base material causes corrosive material removal. A sacrificial anode 3 is therefore advantageously made of zinc used because this material compared to the doctor blade 10th or the leveling bars represent the less noble material, because in practice these are mostly made of iron or an iron alloy are manufactured and thus subject to corrosion are.

Die Opferanode 3 wird auch mit dem Streichrakel 10 durch eine Leitung elektrisch verbunden, wobei beide gleichzeitig mit der wäßrigen Streichmasse 4 auf der Papierbahn 11 in Berührung kommen. Dadurch fließt ein elektrischer Strom von dem Streichrakel 10 zur Opferanode 3 und führt zu einem korrosiven Materialabtrag nahezu nur an der Anode 3, so daß sich der korrosive Verschleiß am Streichrakel 10 verringert und die Standzeit erhöht wird.The sacrificial anode 3 is also with the doctor blade 10 by a Line electrically connected, both simultaneously with the aqueous coating slip 4 on the paper web 11 in contact come. This causes an electric current to flow from the doctor blade 10 to the sacrificial anode 3 and leads to corrosive material removal almost only at the anode 3, so that the corrosive Wear on the doctor blade 10 reduced and the service life is increased.

Zur Verstärkung dieses Effektes wird zwischen die Elektroden 3, 10 noch zusätzlich eine Gleichspannungsquelle 6 geschaltet, bei dem die Anode 3 mit dem Pluspol und die Kathode 10 mit dem Minuspol der Spannungsquelle 6 verbunden ist. Der Pluspol ist gleichzeitig auch mit der Dosierlamelle 9 verbunden und kann auch mit weiteren Streichrakeln in Verbindung stehen, so daß auch an diesen Auftragselementen kaum korrosionsbedingter Materialabtrag erfolgen wird. Zur weiteren Verbesserung des Korrosionsschutzes ist noch eine zweite Opferanode 3a vorgesehen, die unmittelbar im Rücklauf der Streichmasse am Streichrakel 10 angeordnet ist. Dadurch entsteht ein etwa gleich großer Stromfluß von den Auftragselementen 9, 10 zu den Opferanoden 3, 3a, so daß ein gleichmäßiger Materialabtrag an beiden Anoden 3, 3a erreichbar ist. Hierdurch wird ein optimaler Korrosionsschutz an den Auftragselementen 9, 10 bewirkt. Ein derartiger Korrosionsschutz ist auch bei Egalisierungsrollen oder vergleichbaren Streich- und Auftragsvorrichtungen einsetzbar, die aus korrosivem Material bestehen und mit der elektrolytischen anionischen Streichmasse in Berührung kommen.To reinforce this effect is between the electrodes 3, 10 additionally switched a DC voltage source 6, in which the anode 3 with the positive pole and the cathode 10 with the The negative pole of the voltage source 6 is connected. The plus pole is at the same time connected and can with the metering lamella 9 also in connection with other doctor blades, so that hardly any corrosion-related material removal on these application elements will be done. To further improve corrosion protection a second sacrificial anode 3a is also provided, the directly in the return of the coating slip on the doctor blade 10 is arranged. This creates an approximately the same size Current flow from the order elements 9, 10 to the sacrificial anodes 3, 3a, so that a uniform material removal on both anodes 3, 3a can be reached. This provides optimal protection against corrosion caused on the order elements 9, 10. Such one Corrosion protection is also with leveling rolls or comparable coating and application devices can be used, which consist of corrosive material and with the electrolytic anionic coating slip come into contact.
