Abstract

The press mantle, especially for the press section of a papermaking machine to extract water from the wet pulp, is a belt (11) of a matrix material (12) such as polyurethane or rubber, in one or more layers. The surface (17,13) towards and/or away from the fibre web has a surface coating (20). Preferably the surface coating (20) is a closed surface coating, over the whole surface (17,13) of the belt towards and/or away from the web, structured with ridges, grooves or drillings (18). The matrix material (12) of the belt (11) is an elastomer in a number of layers with differing concentrations of particles of the basic material, such as stone or ceramic or glass-powder. The surface coating is a bonded organic monomer. A chemical bond, between the belt surface and the coating, is by chemical plugging or an adhesive. The coating (20) is applied to the belt (11) after its prodn. The coating (20) has hydrophilic or hydrophobic characteristics.

Description

Die Erfindung betrifft einen Preßmantel für eine Preßvorrich tung zur Bearbeitung einer Stoffbahn, insbesondere zur Ent wässerung einer Papierbahn in einem Preßspalt einer Papierma schine, mit einem ein- oder mehrschichtigen aus elastomerem Matrix-Material bestehenden Band. The invention relates to a press shell for a Preßvorrich processing for processing a material web, in particular for Ent dewatering a paper web in a press nip of a machine Papierma, existing with a mono- or multi-layer of elastomeric matrix material band.

Ein derartiger Preßmantel ist aus der DE 44 11 620 A1 be kannt und wird in der Praxis insbesondere in Preßvorrichtun gen eingesetzt, bei denen eine Papierbahn durch einen Preß spalt geführt wird, der zwischen zwei Preßelementen, bei spielsweise einem dem Preßmantel zugeordneten Preßschuh und einer Preßwalze, gebildet ist. Such a press jacket is known from DE 44 11 620 A1 be known and is used in practice, particularly in Preßvorrichtun gene in which a paper web is guided gap by a press, between two presser members, with play, a assigned to the press cover press shoe and a press roll is formed. Durch den zwischen diesen Preßelementen ausgebildeten Preßspalt läuft die zu entwäs sernde Stoffbahn zusammen mit dem Preßmantel und mindestens einem weiteren Band zur Aufnahme der beim Preßvorgang anfal lenden Preßflüssigkeit. Through the press nip formed between said pressure elements running to entwäs-improving material web along with the press jacket, and at least one further belt for receiving the anfal lumbar extruding liquid during the pressing process. Der Preßmantel ist in der Regel end los und kann außerhalb des Preßspaltes über Leitwalzen ge führt sein. The press jacket is going end in the rule and may be outside of the press nip ge over guide rolls leads. Die Länge des Preßmantels in Umlaufrichtung hängt von der Art der Anwendung ab. The length of the press jacket in the direction of rotation depends on the type of application.

Der bekannte Preßmantel besteht aus mehreren Schichten und weist eine Trägerschicht auf, in der zur Verstärkung der Preßmantelschicht quer und längs zur Bahnlaufrichtung ver laufende Verstärkungsfäden vorgesehen sein können, sowie eine weitere Schicht, die in direktem Kontakt zur zu ent wässernden Stoffbahn stehen kann und eine erhöhte Verschleiß festigkeit besitzt. The known press shell consists of several layers and comprises a backing layer, may be provided in the gain of the Preßmantelschicht transversely and longitudinally ver to the web running direction running reinforcing threads and a further layer, which may be in direct contact with the at ent watering panel and an increased has wear resistance. Dazu werden in das elastomere Matrix- Material, aus dem auch die Trägerschicht aufgebaut ist, ver schleißfeste Partikel aus Gesteinsmehl, keramischem Pulver oder Glasfritte eingearbeitet. For this purpose, in the elastomeric matrix are material from which the support layer is constructed ver schleißfeste particles of rock powder, ceramic powder or glass frit incorporated.

Preßmäntel dieser Art unterliegen neben dem mechanischen Ab rieb auch andersgeartetem Verschleiß, insbesondere bedingt durch die in der Praxis verwendeten, auf den Mantel einwir kenden chemischen Mittel, die zu einem Quellen des Matrixma terials und damit insbesondere in Verbindung mit der sich im Betrieb ergebenden Erwärmung zu einer starken Alterung und zu einer entsprechenden Verringerung der Lebensdauer führen können. Press jackets have historically been subject in addition to the mechanical Ab-wrote andersgeartetem wear, especially due to the used in practice, on the mantle einwir kenden chemical means to be a source of Matrixma terials and thus in particular in connection with the resulting operational warming a strong aging and can lead to a corresponding reduction in service life. Außerdem sind als Folge davon Qualitätseinbußen bei der jeweils zu bearbeitenden Stoffbahn nicht auszuschließen. In addition, as a result of loss of quality to be worked each panel can not be excluded.

Aufgabe der Erfindung ist es daher, einen Preßmantel der ein gangs genannten Art zu schaffen, der eine erhöhte Lebensdau er besitzt und bessere Eigenschaften beim Einsatz in der Pa pierherstellung aufweist. The object of the invention is therefore to provide a press cover of a initially mentioned type, which it has an increased lifetime than and has better properties when used in Pa pierherstellung.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Band auf seiner der Stoffbahn zugewandten und/oder abgewand ten Oberfläche eine Oberflächenbeschichtung aufweist. This object is inventively achieved in that the tape on its side facing the fabric web and / or abgewand th surface has a surface coating.

Die Oberflächenbeschichtung verhindert das Eindringen von chemischen Stoffen, die beim Papierherstellungsprozeß ver wendet werden oder dabei entstehen. The surface coating prevents the penetration of chemicals which applies in the papermaking process are ver or in the process arise. Durch die Oberflächenbe schichtung wird die Güte des Matrix-Materials des Preßman tels verbessert, denn die Oberflächenbeschichtung erhöht den Verschleißwiderstand und verringert so den Abrieb. coating by the Oberflächenbe the quality of the matrix material of the means of Pressman is improved, because the surface coating increases the wear resistance and thus reduces abrasion. Ein weite rer Vorteil ist, daß die Oberflächenbeschichtung auch die Reibung des Materials herabsetzt, so daß die Antriebsmittel mit geringerer Energie arbeiten können. A wide rer advantage that the surface coating also reduces the friction of the material, so that the drive means may operate with lower power. Die Oberflächenbe schichtung erhöht die Beständigkeit des Preßmantels gegen über Filzwaschmitteln und Zuschlagsstoffen im Fasermaterial bei der Papierverarbeitung. The Oberflächenbe coating increases the resistance of the press jacket against Filzwaschmitteln and aggregates in the fiber material in paper processing. Ferner wird auch die Wasser- und Ölaufnahme des Matrix-Materials und somit dessen Quellung verhindert. Further, the water and oil absorption of the matrix material, and thus its swelling is prevented. Weitere vorteilhafte Effekte sind-eine höhere Temperaturbeständigkeit des Preßmantels und eine bessere Ab lösung der Stoffbahn vom Preßmantel nach dem Preßvorgang. Further advantageous effects are-a higher temperature resistance of the press jacket and a better solution from the panel by pressing jacket after the pressing process.

Die Verbesserung der Stoffbahnabgabe wird durch hydrophobe Eigenschaften der Oberflächenbeschichtung erzielt. The improvement of the web delivery is achieved by hydrophobic properties of the surface coating. Aber auch eine hydrophile Eigenschaft der Oberflächenbeschichtung kann bei Bedarf erzielt werden. But a hydrophilic property of the surface coating can be achieved if necessary.

Bei einer vorteilhaften Weiterbildung der Erfindung wird die Oberflächenbeschichtung an jeder Seite des Preßmantels aufge bracht. In an advantageous development of the invention, the surface coating is placed up on each side of the press jacket. Dabei deckt die Oberflächenbeschichtung auch Vertie fungen wie Nuten, Rillen und Bohrungen in der Oberfläche des Preßmantels ab. The surface coating also covers Vertie levies as grooves, channels, and holes in the surface of the press jacket from. Je nach Bedarf kann die Oberflächenbeschich tung auf den Preßmantel derart aufgebracht sein, daß die Au ßenfläche der Oberflächenbeschichtung frei von Vertiefungen und Erhöhungen und infolgedessen plan ist, obwohl die Ober fläche des Preßmantels unter der Oberflächenbeschichtung rauh oder uneben ist. As required, the processing Oberflächenbeschich can be applied over the sleeve such that the Au of the surface coating ßenfläche free of pits and projections and consequently is flat, although the upper surface of the press cover of the rough surface coating or is uneven.

Die Oberflächenbeschichtung kann durch Oberflächenaktivie rung ausgewählte organische Monomere aufweisen, die auf die Oberfläche des Bandes des Preßmantels chemisch aufgepfropft oder mit dieser verbunden sind. The surface coating may by Oberflächenaktivie tion have selected organic monomers are chemically grafted onto the surface of the belt or of the press jacket connected thereto. Die Oberflächenbeschichtung kann aber auch durch einen Haftvermittler mit dem elastome ren Matrix-Material des ein- oder mehrschichtigen Preßman tels verbunden sein. However, the surface coating may be means of connected by a coupling agent with the elastome ren matrix material of the monolayer or multilayer Pressman.

Weitere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen definiert. Further advantageous developments of the invention are defined in the dependent claims.
