Abstract
Description
Die Erfindung betrifft Gipskartonplatten, mit einem flächigen Gipskern und einer zumindest auf dessen Flächen, insbesondere aber auch auf dessen Kanten, wenigstens den Längskanten, vorgesehenen Kartonummantelung mit wenigstens einer Kartonbahn.The The invention relates to plasterboard, with a flat plaster core and one at least on its surfaces, but especially on the edges, at least the longitudinal edges, provided Kartonummantelung with at least one cardboard web.
Aus der Praxis sind Gipskartonplatten bekannt, die im Wesentlichen aus Stuckgips und einer Kartonummantelung bestehen und üblicherweise auf Bandanlagen im kontinuierlichen Betrieb hergestellt werden. Zur Erzielung bestimmter Eigenschaften kann der kartonummantelte Gipskern Zusätze oder beigefügte Zuschlagsmaterialien beinhalten.Out In practice, plasterboard is known, which consists essentially of Stucco and a cardboard casing are made and usually be produced on conveyor systems in continuous operation. To achieve certain properties, the carton sheathed Gypsum core additives or attached Include additional materials.
Die Eigenschaften der fertigen Gipskartonplatte resultieren insofern aus den Eigenschaften des Gipskerns und der Verbundenheit von Gipskern und Kartonummantelung. Hierbei wird die Verbundenheit im Wesentlichen durch das Abbindeverhalten des Gipses und durch die Penetrationsfähigkeit der Gipsseite der Kartonummantelung, die u.a. von einer richtigen Leimung abhängt, bestimmt.The Properties of the finished plasterboard result in this respect from the properties of the gypsum core and the bondage of gypsum core and cardboard sheathing. Here, the attachment is essentially by the setting behavior of the gypsum and by the penetration ability the plaster side of the cardboard casing, which i.a. from a right one Sizing depends certainly.
Für ein optimales Abbindeverhalten kann der Gips Zusatzstoffe wie Stärke, Beschleuniger, Verzögerer und Gipsstoff aufweisen, und es kann ein für das gewünschte Abbindeverhalten optimiertes Wasser/Gips-Verhältnis vorgesehen sein.For an optimal Setting behavior, the gypsum additives such as starch, accelerator, retarder and gypsum, and it can be optimized for the desired setting performance Water / gypsum ratio be provided.
Nachteilig hierbei ist, dass in der Praxis immer wieder zu Haftungsproblemen zwischen Gipskern und Kartonummantelung bei der Herstellung und auch bei der Verarbeitung von Gipskartonplatten auftreten.adversely Here is that in practice again and again to liability problems between gypsum core and cardboard casing in the manufacture and also occur during the processing of plasterboard.
Die verschiedenen Zuschlagstoffe, wie z.B. Stärke, sind zum einen kostenintensiv und stellen erhöhte Anforderungen an die Herstellgenauigkeit bei der verwendeten Gipsmischung. Zum anderen wird aus ökologischen Überlegungen von der Verwendung bestimmter Zuschlagstoffe auch gerne abgesehen.The various additives, e.g. Strength are expensive and increase Requirements for the manufacturing accuracy of the plaster mixture used. On the other hand, for ecological reasons apart from the use of certain additives.
Der hierzu vorbekannte Stand der Technik sowie die hierin begründeten Nachteile wurden bereits eingangs ausgeführt. Es ist insoweit Aufgabe der Erfindung, eine gattungsgemäße Gipskartonplatte anzugeben, die eine verbesserte Haftung zwischen Gipskern und Kartonummantelung ohne oder mit reduzierter Zugabe von Zuschlagsmaterialien oder anderen Haftungsverbesserern im Kontaktbereich von Gipskern und Kartonummantelung aufweist.Of the Previously known prior art as well as the disadvantages justified herein were already mentioned at the beginning. It is the object of the invention, a generic plasterboard indicate the improved adhesion between gypsum core and cardboard casing without or with reduced addition of aggregates or other Adhesion improvers in the contact area of gypsum core and cardboard sheathing having.
Diese Aufgabe wird gelöst durch eine gattungsgemäße Gipskartonplatte, bei der zumindest eine Kartonbahn während der Herstellung der Gipskartonplatte auf wenigsten einer ihrer Seiten, insbesondere auf ihrer Sichtseite, aber auch oder nur auf ihrer Rückseite, mit Ultraschall beaufschlagt worden ist, so dass durch die Aktivierung von Fibrillen eine Oberflächenvergrößerung des Papiers erfolgt, die eine bessere Haftung zwischen Gipskern und Papier bewirkt.These Task is solved through a generic plasterboard, at least one board web during the manufacture of the gypsum board on at least one of their pages, especially on their visual side, but also or only on the back, has been subjected to ultrasound, so by activation of fibrils a surface enlargement of the Paper takes place, which gives a better adhesion between gypsum core and Paper causes.
Hierdurch sind zum einen die Poren in der Außenschicht des Gipskerns reduziert, wodurch eine bessere Haftung zwischen Gipskern und Papier resultiert. Zum anderen ist durch ein stärkeres und tieferes Eindringen des Gips in den Karton eine verbesserte Verbindung zwischen Gipskern und Papier gegeben.hereby On the one hand, the pores in the outer layer of the gypsum core are reduced, whereby a better adhesion between gypsum core and paper results. On the other hand is through a stronger and deeper penetration of the gypsum into the cardboard improved Given connection between gypsum core and paper.
Durch gezielte Ultraschallbehandlung kann zudem ein mehrlagiger Kern mit porenarmen Außenlagen und einer porenreichen Innenlage resultieren, der einerseits eine gut haftende Verbindung mit dem Papier aufweist und andererseits ein geringes Gewicht hat.By Targeted ultrasound treatment can also be a multi-layered core with pore-poor outer layers and a pore-rich inner layer result, on the one hand a has good adhesion with the paper and on the other hand has a low weight.
Auch kann zumindest eine Kartonbahn, insbesondere unmittelbar, vor dem Zuführen des insbesondere breiförmigen Gips auf ihrer später dem Gips zugewandten Seite mit Ultraschall beaufschlagt worden sein, so dass durch die Aktivierung von Fibrillen eine Oberflächenvergrößerung des Papiers, und somit eine bessere Haftung zwischen Gipskern und Papier, resultiert. Eine höhere Festigkeit des Kartons sowie eine erhöhte Plattenfestigkeit werden insoweit erreicht.Also At least one cardboard web, in particular directly, before the Respectively of the particular pulp-shaped Plaster on her later be exposed to the gypsum facing side with ultrasound, so that by the activation of fibrils a surface enlargement of the Paper, and thus better adhesion between gypsum core and paper, results. A higher one Strength of the carton and increased plate strength are achieved so far.
Dabei kann die Beaufschlagung mit Ultraschall durch eine Ultraschallschwingungsvorrichtung ohne Gegenwerkzeug erfolgt sein, so dass eine entsprechende Behandlung des Papiers ohne aufwändigen technische Anlagen, und damit an vielen unterschiedlichen Positionen ohne Einschränkungen aufgrund des apparativen Aufwands, möglich ist.there the application of ultrasound by an ultrasonic vibration device without Counter-tool should be done, so that appropriate treatment of the paper without elaborate technical equipment, and thus in many different positions without restrictions due to the expenditure on equipment, is possible.
Erfindungsgemäß kann der Gipskern durch Zuführung eines, insbesondere breiförmigen, mit porenarmen Außenlagen und einer porenreichen Innenlage ausgebildeten Gips, mehrlagig ausgebildet sein, so dass durch die Vielzahl an Poren in der Innenlage ein geringes Gewicht der Gipskartonplatte resultiert, wohingegen die Porenarmut der Außenlagen eine ausreichend große Fläche für die Verbindung des Gipskerns mit der Kartonummantelung zur Verfügung stellt, da eine Oberflächenverringerung durch eine Vielzahl von Poren vermieden wird.According to the invention of Gypsum core by feeder one, in particular pulp-shaped, with low-pore outer layers and a pore-rich inner layer formed gypsum, be formed multi-layered, so that a small amount due to the large number of pores in the inner layer Weight of the plasterboard results, whereas the pore poverty the outer layers a big enough one area for the Provides connection of the gypsum core with the cardboard sheath, because a surface reduction by a large number of pores is avoided.
Hierzu kann der Gipskern auch durch Ultraschallbeaufschlagung zumindest einer Kartonbahn, insbesondere unmittelbar, nach dem Zuführen des breiförmigen Gips auf ihrer dem Gips abgewandten Seite mehrlagig mit porenarmen Außenlagen und einer porenreichen Innenlage ausgebildet sein, so dass durch die Ultraschallbehandlung eine zusätzliche Verbindung zwischen Gipskern und Kartonummantelung bewirkt wird.For this purpose, the gypsum core may also be formed by applying ultrasound to at least one board web, in particular immediately after feeding the gypsum plaster on its side facing away from the gypsum, with pore-poor outer layers and a pore-rich inner layer that the ultrasound treatment causes an additional connection between gypsum core and cardboard casing.
Hierdurch erfolgt zum einen eine Reduktion der Poren in der Außenschicht des Gipskerns, wodurch eine bessere Haftung zwischen Gipskern und Papier bewirkt wird. Zum anderen wird durch ein stärkeres und tieferes Eindringen des Gips in den Karton eine bessere Verbindung zwischen Gipskern und Papier bewirkt.hereby On the one hand, the pores in the outer layer are reduced of the gypsum core, resulting in better adhesion between gypsum core and paper is effected. On the other hand, by a stronger and deeper penetration of plaster in the cardboard a better connection between gypsum core and paper causes.
Durch gezielte Ultraschallbehandlung kann ein mehrlagiger Kern mit porenarmen Außenlagen und einer porenreichen Innenlage ausgebildet werden, der einerseits eine gut haftende Verbindung mit dem Papier aufweist und andererseits ein geringes Gewicht hat.By Targeted ultrasound treatment can be a multi-layered core with low-pore Outer layers and a pore-rich inner layer are formed, on the one hand has a good adhesion with the paper and on the other hand has a low weight.
