Abstract
Das Verfahren dient zur Erzeugung von mehrlagigem Karton oder Verpackungspapier. Dazu wird der Rohstoff, insbesondere gemischtes Altpapier (M), nach eventueller Reinigung (2) einer Fraktion (3) unterzogen, bei der eine Kurzfaserfraktion (F1) und eine Langfaserfraktion (F2) anfallen. Bei der Produktion des Verpackungspapiers oder Kartons wird die Kurzfaserfraktion (F1) in die Deckenlage gefahren.The method is used to produce multi-ply cardboard or packaging paper. For this purpose, the raw material, in particular mixed waste paper (M), after possible cleaning (2) subjected to a fraction (3), in which a short fiber fraction (F1) and a long fiber fraction (F2) are incurred. When producing the packaging paper or cardboard, the short fiber fraction (F1) is moved to the ceiling position.
Description
Die Erfindung bezieht sich auf ein Verfahren gemäß Oberbegriff des Anspruchs 1.The The invention relates to a method according to the preamble of claim 1.
Es ist bekannt, in mehrlagigen Papier- oder Kartonprodukten unterschiedliche Stoffsorten zu verwenden. Dabei kann man sowohl durch Wal der Rohstoffe, als auch in geeigneten Verfahrensschritten der Stoffaufbereitung gezielt Einfluss auf die später auf der Papiermaschine erzeugten Papier- oder Karton-Qualität nehmen. Auf diese Weise werden – wie an sich bekannt – den Wünschen entsprechend die Eigenschaften des Papier- oder Kartonproduktes gesteuert. Die vorliegende Erfindung zielt insbesondere auf die Erzeugung von mehrlagigem Verpackungspapier oder Karton, wozu z. B. Papier- oder Kartonmaschinen mit Mehrlagenstoffauflauf oder mehreren Stoffaufläufen verwendet werden. Dabei wird die Lage des Deckenstoffes mit Fasern größerer Länge (Langfaserstoff) und die Lagen der Rückseite und/oder Mittelschicht mit Fasern geringer Länge (Kurzfaserstoff) gebildet.It is known to be different in multilayer paper or board products To use types of fabric. You can do this both by whale of raw materials, as well as in suitable process steps of stock preparation purposefully influence the later on the paper machine paper or cardboard quality. To this Wise - as is well known - the wishes according to the characteristics of the paper or cardboard product controlled. The present invention particularly aims at the Production of multi-ply packaging paper or cardboard, including z. B. paper or board machines with Mehrlagenstoffauflauf or more headboxes be used. Here, the position of the cover fabric with fibers greater length (long fiber) and the Layers of the back and / or middle layer with fibers less Length (short fiber) formed.
Bei der Wahl der einzusetzenden Rohstoffe spielen neben der Qualität auch ihre Kosten eine beträchtliche Rolle. Das Bestreben, möglichst preiswerte Rohstoffe zu verwenden, sowie abfallwirtschaftliche Gesichtspunkte führen dazu, dass in vielen Fällen gemischte Rohstoffe, z. B. Altpapiere, mit breitem Faserlängenspektrum in der Produktion eingesetzt werden sollen.at the choice of the raw materials to use next to the quality their costs also play a significant role. The effort, to use inexpensive raw materials as well as waste management Considerations mean that in many cases mixed raw materials, eg B. recovered paper, with a broad fiber length spectrum to be used in production.
Es ist Aufgabe der Erfindung, ein Verfahren zu schaffen, mit dem es gelingt, die Qualität des Papiers oder Kartons auf besonders einfache und wirtschaftliche Art zu verbessern und/oder die Kosten zu senken.It It is an object of the invention to provide a method with which it manages to get the quality of the paper or cardboard on extra simple and economical way to improve and / or reduce costs to lower.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Ein mit Hilfe des Verfahrens hergestelltes Verpackungspapier oder ein entsprechend hergestellter Karton weist eine Deckenlage auf, deren Stoffzusammensetzung den Vorteil einer guten optischen Qualität hat. Da die gebildete Kurzfaserfraktion im Vergleich zum Ausgangsrohstoff eine erhöhte Faseranzahl und eine reduzierte mittlere Faserlänge hat, erfüllt sie in besonderer Weise die Anforderungen an eine Deckenlage. Opazität, Bedruckbarkeit und Oberflächenaussehen sind für diese Schicht besonders wichtig.One produced by the process of packaging paper or a Correspondingly produced cardboard has a layer of blanket whose composition has the advantage of good optical quality. Because the formed short fiber fraction compared to the starting raw material one has increased number of fibers and a reduced average fiber length, It fulfills the requirements of a particular kind Ceiling location. Opacity, printability and surface appearance are especially important for this layer.
