Definitions
- the invention relates to a method for applying a double layer, consisting of primer and top coat, with a liquid to pasty application medium, in particular aqueous pigment suspension on at least one side of a running paper, cardboard or other fibrous web during their production and / or finishing.
- blade coaters In the production or refinement of paper, which had to be treated with a double line, ie primer and top coat, at least the top coat was previously applied with blade coaters (blade coaters). These coaters work with a squeegee element (blade), with which the application medium applied in excess is brought to the desired coating weight and thereby evened out or leveled. These coaters have poor runnability, especially at higher machine and web speeds. In addition, a separate application unit must be provided for each paper page.
- misting also depends heavily on the absorption capacity of the fibrous web. In the case of the top coat this absorption capacity is significantly reduced by the precoat, so that it can come here to a particular extent to Misting.
- the invention is therefore based on the object of specifying a method which avoids the disadvantages of the prior art.
- the object is achieved according to the characterizing part of claim 1, characterized in that for the applied to the fibrous web double layer, ie precoating and top coat, each a known film applicator for applying the coating medium is used in an indirect manner, wherein for the precoat such a coating medium is to be used which contains platelet-shaped pigments. This is the case, for example, with kaolin. It is expedient if the application medium for the precoat has an aspect ratio (i.e., length-to-thickness ratio of a platelet) of> 5, preferably> 15.
- the structure of the precoat can be broken up in such a way that the precoat becomes more open and its absorption capacity increases. As a result, the subsequent top coat applied to the precoat can be better drained. For the first time, it is possible to use high coating weights or application quantities without having to do so unwanted misting comes.
- the pre-painted web has low absorbency.
- the cause is the relatively dense, compact and impermeable precoat, which is used in the form of mostly ground, not too fine calcium carbonate with natural, broad particle size distribution as a pigment, in particular for the achievement of opacity and whiteness is considered. Therefore, especially when applying the top coat, even at low order quantity the dreaded misting occurs.
- the inventive method can be carried out at a high web speed during the production and / or finishing of the fibrous web.
- This web or machine speed can now be more than 1000 m / min, in particular more than 1200 m / min and preferably more than 1300 m / min, whereby the economy of the Process or the web production is particularly high.
- FIG. 1 shows the FIG. 1 in a rough schematic representation of the principle of the method according to the invention.
- FIG. 1 It is shown that a fibrous web 1, which is already predried, is provided with a double layer D.
- a first film applicator 2 for achieving a first coating layer or a precoat 3 and a second Filmrlandstechnik 4, which is the applicator 2 in the path L of the fibrous web 1 downstream and the achievement of a second coating layer or a top coat 5 is present.
- the first film applicator 2 consists of two with each other a Nip N1 forming applicator rollers 2.1 and 2.2, each of which a job unit 2.3 and 2.4 is assigned. With the application units 2.3 and 2.4, the application medium M1 is first applied to the surface of the two application rollers and then transferred in the nip N1 at the same time to both web sides 1a and 1b (with simultaneous double-sided coating). That on the web page 1a and web page 1b Applied application medium M1 is shown in dashed lines.
- the second film applicator 4 is identical to the first film applicator 2, which is very advantageous in terms of web guide, spare parts inventory, space requirements, maintenance, installation, etc. Accordingly, the application rollers are denoted by 4.1 and 4.2 and the associated application units with 4.3 and 4.4, the nip with N2 and the application medium with M2.
- the top coat 5 is shown by dotted line. This is applied by way of example only one side of the web page 1a, which is why the application unit was 4.4 swung from the applicator roll 4.1.
- the following pigment composition is chosen in the example: 90 parts of Hydrocarb 60 (calcium carbonate) and 10 parts of Capim NP (kaolin), the kaolin having an aspect ratio (width / thickness ratio) of 20.
- the rest of the coating M1 form latex and thickener.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Aufbringen einer Doppelschicht, bestehend aus Vorstrich und Deckstrich, mit einem flüssigen bis pastösen Auftragsmedium, insbesondere wässriger Pigmentsuspension auf wenigstens eine Seite einer laufenden Papier-, Karton- oder anderen Faserstoffbahn bei deren Herstellung und/oder Veredelung.The invention relates to a method for applying a double layer, consisting of primer and top coat, with a liquid to pasty application medium, in particular aqueous pigment suspension on at least one side of a running paper, cardboard or other fibrous web during their production and / or finishing.
Bei der Herstellung bzw. der Veredelung von Papier, die mit einem Doppelstrich, also Vorstrich und Deckstrich zu behandeln waren, wurde zumindest der Deckstrich bisher mit Blade-Coatern (Klingenstreichaggregaten) aufgebracht. Diese Coater arbeiten mit einem Rakelelement (blade bzw. Klinge), mit welchem das im Überschuss aufgebrachte Auftragsmedium auf das gewünschte Strichgewicht gebracht und dabei vergleichmäßigt bzw. eingeebnet wird. Diese Coater haben insbesondere bei höheren Maschinen- und Bahngeschwindigkeiten einen schlechten Laufwirkungsgrad (runnability). Zudem ist für jede Papierseite ein eigenes Auftragsaggregat vorzusehen.In the production or refinement of paper, which had to be treated with a double line, ie primer and top coat, at least the top coat was previously applied with blade coaters (blade coaters). These coaters work with a squeegee element (blade), with which the application medium applied in excess is brought to the desired coating weight and thereby evened out or leveled. These coaters have poor runnability, especially at higher machine and web speeds. In addition, a separate application unit must be provided for each paper page.
Man versuchte deshalb, auch den Deckstrich mit so genannten Filmauftragswerken aufzubringen, wobei zwei Auftragswalzen miteinander einen Nip (Pressspalt) bilden, den die zu beschichtende Faserstoffbahn durchläuft und wo von wenigstens einer der Auftragswalzen das auf sie aufgebrachte Auftragsmedium im Nip an die Faserstoffbahn übertragen wird. Bei dieser Art des Auftrags ist zwar der Laufwirkungsgrad besser als beim Blade-Streichen, aber die aufzubringenden Strichgewichte in g/m2 sind in Ihrer Größenordnung bzw. Menge hierbei stark begrenzt, weil beim Abzug der beschichteten Faserstoffbahn aus dem Nip ein so genanntes, unerwünschtes Misting auftritt. Dieses ist durch Abspritzen von Auftragsmedium in die Umgebung, an Maschinenteile, aber auch an die herzustellende und/oder zu veredelnde Faserstoffbahn gekennzeichnet, wodurch im Endeffekt die Auftragsqualität leidet. Je höher die Strichgewichte sind und je höher die Laufgeschwindigkeit der Faserstoffbahn ist, desto intensiver tritt das Misting auf. Bei doppelt gestrichenen Bahnen ist dieser negative Effekt besonders ausgeprägt.It was therefore also attempted to apply the cover coat with so-called film applicators, wherein two applicator rollers together form a nip (press nip) through which the fibrous web to be coated passes and where at least one of the applicator rolls transfers the application medium applied to it in the nip to the fibrous web. Although in this type of job, the running efficiency is better than blade blending, but the applied bar weights in g / m 2 are greatly limited in their magnitude or amount, because when deducting the coated fibrous web from the nip a so-called, undesirable Misting occurs. This is characterized by spraying application medium into the environment, to machine parts, but also to the produced and / or to be refined fibrous web, which ultimately suffers the job quality. The higher the line weights and the higher the speed of the fibrous web, the more intense the misting occurs. For double-coated webs, this negative effect is particularly pronounced.
Misting tritt aber auch bei einem Einfachstrich auf.Misting also occurs in a single stroke.
Das Auftreten von Misting hängt auch stark von der Aufnahmefähigkeit der Faserstoffbahn ab. Im Falle des Deckstrichs ist diese Aufnahmefähigkeit durch den Vorstrich deutlich herabgesetzt, so dass es hier in besonderem Maße zu Misting kommen kann.The occurrence of misting also depends heavily on the absorption capacity of the fibrous web. In the case of the top coat this absorption capacity is significantly reduced by the precoat, so that it can come here to a particular extent to Misting.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren anzugeben, welches die Nachteile des Standes der Technik vermeidet.The invention is therefore based on the object of specifying a method which avoids the disadvantages of the prior art.
Erfindungsgemäß wird die Aufgabe gemäß dem Kennzeichen des Anspruches 1 dadurch gelöst, dass für die auf die Faserstoffbahn aufzubringende Doppelschicht, also Vorstrich und Deckstrich, jeweils ein an sich bekanntes Filmauftragswerk zum Auftragen des Beschichtungsmediums in indirekter Weise verwendet wird, wobei für den Vorstrich ein solches Auftragsmedium verwendet werden soll, das plättchenförmige Pigmente enthält. Das ist beispielsweise bei Kaolin der Fall. Zweckmäßig ist es, wenn das Auftragsmedium für den Vorstrich einen Aspect ratio (d.h. Längen- zu Dickenverhältnis eines Plättchens) von >5, vorzugsweise >15 aufweist.According to the invention the object is achieved according to the characterizing part of claim 1, characterized in that for the applied to the fibrous web double layer, ie precoating and top coat, each a known film applicator for applying the coating medium is used in an indirect manner, wherein for the precoat such a coating medium is to be used which contains platelet-shaped pigments. This is the case, for example, with kaolin. It is expedient if the application medium for the precoat has an aspect ratio (i.e., length-to-thickness ratio of a platelet) of> 5, preferably> 15.
Es ist der Verdienst des Erfinders erkannt zu haben, dass der Vorstrich das Auftreten von Misting im Deckstrich stark begünstigt. Wird nun ein spezielles Auftragsmedium, also das plättchenförmige Pigmente enthaltende Auftragsmedium, für den Vorstrich verwendet, lässt sich Misting im Deckstrich in überraschender Weise verringern oder sogar vollständig eliminieren.It is the merit of the inventor to have recognized that the primer favors the occurrence of misting in the top coat. If now a special application medium, ie the coating medium containing application medium, used for the precoat, misting in the top coat can be surprisingly reduced or even completely eliminated.
Durch erfindungsgemäßes Zugeben von Kaolin (auch Talkum ist möglich) zum üblicherweise auf Calciumcarbonat basierenden Vorstrich, lässt sich die Struktur des Vorstriches so aufbrechen, dass der Vorstrich offener wird und seine Absorptionsfähigkeit steigt. Dadurch kann der nachfolgende und sich auf den Vorstrich auflegende Deckstrich besser entwässern. So ist es erstmals möglich, hohe Strichgewichte bzw. Auftragsmengen zu verwenden, ohne dass es zum unerwünschten Misting kommt.By adding kaolin according to the invention (talc is also possible) to the precoat, which is usually based on calcium carbonate, the structure of the precoat can be broken up in such a way that the precoat becomes more open and its absorption capacity increases. As a result, the subsequent top coat applied to the precoat can be better drained. For the first time, it is possible to use high coating weights or application quantities without having to do so unwanted misting comes.
Misting entsteht bekanntlich bei hohen Maschinengeschwindigkeiten, wenn im Nip die an die Faserstoffbahn übertragene Streichfarbe, d.h. das Auftragsmedium nicht genügend immobilisiert werden kann.
Dies ist insbesondere dann der Fall, wenn die Auftragsmenge hoch ist. Neben den Eigenschaften der Streichfarbe selbst, spielt hierbei das Absorptionsvermögen des Roh-Faserstoffs bzw. Rohpapieres oder wie eben im Fall eines Vor- und Deckstriches, das Absorptionsvermögen des Vorstriches eine entscheidende Rolle.Misting is known to occur at high machine speeds, if in the nip the coating color transferred to the fibrous web, ie the application medium, can not be sufficiently immobilized.
This is especially the case when the order quantity is high. In addition to the properties of the coating color itself, the absorption capacity of the raw fibrous material or raw paper or, as in the case of a pre-coating and top coating, the absorption capacity of the pre-coating plays a decisive role.
Der Erfinder hat auch herausgefunden, dass beim Doppelfilmstreichen die vorgestrichene Bahn nur ein geringes Absorptionsvermögen besitzt. Als Ursache wird der relativ dichte, kompakte und undurchlässige Vorstrich, der in Form von zumeist gemahlenem, nicht zu feinen Calciumcarbonat mit natürlicher, breiter Korngrößenverteilung als Pigment, insbesondere zur Erzielung von Opazität und Weiße eingesetzt wird, angesehen. Daher tritt vor allem beim Aufbringen des Deckstriches, selbst bei niedriger Auftragmenge das gefürchtete Misting auf.The inventor has also found that in double-film painting, the pre-painted web has low absorbency. The cause is the relatively dense, compact and impermeable precoat, which is used in the form of mostly ground, not too fine calcium carbonate with natural, broad particle size distribution as a pigment, in particular for the achievement of opacity and whiteness is considered. Therefore, especially when applying the top coat, even at low order quantity the dreaded misting occurs.
Mit dem erfindungsgemäßen Verfahren ist es nun möglich, sowohl den Vorstrich, als auch den Deckstrich ohne Misting mit je einem Filmauftragswerk aufzubringen, wobei hohe Auftragsmengen bzw. Strichgewichte möglich sind, dergestalt, dass für den Deckstrich mehr als 6g/m2, insbesondere 8g/m2, vorzugsweise mehr als 10g/m2 aufgetragen werden.
Damit verbessert sich die Runnability in der Herstellungs- oder Veredelungsmaschine und auch der Abdeckungsgrad der Faserstoffbahn mit dem Auftragsmedium, was sich auf die spätere Bedruckbarkeit positiv auswirkt.With the method according to the invention, it is now possible to apply both the precoat and the top coat without misting, each with a film applicator, with high application quantities or line weights are possible, such that for the top coat more than 6g / m 2 , especially 8g / m 2 , preferably more than 10g / m 2 are applied.
This improves the runnability in the production or finishing machine and also the degree of coverage of the fibrous web with the application medium, which has a positive effect on the later printability.
Darüber hinaus kann das erfindungsgemäße Verfahren bei einer hohen Bahngeschwindigkeit während der Herstellung und/oder Veredelung der Faserstoffbahn durchgeführt werden. Diese Bahn- bzw. Maschinengeschwindigkeit kann nun mehr als 1000 m/min, insbesondere mehr als 1200 m/min und vorzugsweise mehr als 1300 m/min betragen, wodurch die Wirtschaftlichkeit des Verfahrens bzw. die Bahnproduktion besonders hoch ist.In addition, the inventive method can be carried out at a high web speed during the production and / or finishing of the fibrous web. This web or machine speed can now be more than 1000 m / min, in particular more than 1200 m / min and preferably more than 1300 m / min, whereby the economy of the Process or the web production is particularly high.
Es soll erwähnt sein, dass im Anschluss an die erfindungsgemäße Doppelbeschichtung und nachfolgenden Trocknung ein Kalandrieren der Faserstoffbahn und/oder weitere Beschichtungsvorgänge vorgenommen werden können. Das ist abhängig davon, in welchem Zustand bzw. in welcher Qualität die Rohpapierbahn vorliegt. Ziel ist ja eine vollständige und gleichmäßige Abdeckung der oftmals bis über 10m breiten Bahn.It should be mentioned that, following the double coating according to the invention and subsequent drying, calendering of the fibrous web and / or further coating operations can be carried out. This depends on the state or quality of the raw paper web. The goal is a complete and even coverage of the often over 10m wide track.
Weitere vorteilhafte Ausgestaltungsmöglichkeiten des erfindungsgemäßen Verfahrens ergeben sich aus weiteren Unteransprüchen.Further advantageous embodiment possibilities of the method according to the invention emerge from further subclaims.
