Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Magazinpapier aus einer Fasern umfassenden Stoffsuspension.The The invention relates to a method for producing magazine paper from a fiber suspension comprising substance.
Bei Magazinpapieren handelt es sich um LWC- und SC-Papiere, d. h. gestrichene und ungestrichene Druckpapiere mit einem relativ geringen Blattgewicht, allgemein zwischen 45 und 72 g/m2.Magazine papers are LWC and SC papers, ie coated and uncoated printing papers having a relatively low sheet weight, generally between 45 and 72 g / m 2 .
Derartige Papiere werden gegenwärtig hauptsächlich aus Fasern von Steinschliff (GW), TMP-Faserstoff oder aus einer Mischung aus GW und DIP (deinktes Altpapier) hergestellt.such Papers are becoming current mainly from stone-ground fibers (GW), TMP-pulp or from one Mixture made of GW and DIP (deinked waste paper).
Dabei liegt der Anteil des relativ preiswerten DIP allgemein unter 50%. Eine aus Kostengründen wünschenswerte Erhöhung des DIP-Anteils scheitert an den hohen Qualitätsanforderungen an diese Magazinpapiere, insbesondere deren optischen und Oberflächeneigenschaften.there the proportion of the relatively cheap DIP is generally below 50%. One for cost reasons desirable increase of the DIP share fails due to the high quality requirements of these magazine papers, in particular their optical and surface properties.
Diese Eigenschaften lassen sich zwar durch eine Zugabe von SGW verbessern, jedoch wirkt sich dies negativ auf die Reißfestigkeit aus.These Properties can be improved by adding SGW, However, this has a negative impact on the tear strength.
Die Aufgabe der Erfindung ist es daher, die Herstellung von Magazinpapier mit möglichst guten optischen und Oberflächeneigenschaften und möglichst hoher Reißlänge zu ermöglichen.The The object of the invention is therefore the production of magazine paper with as possible good optical and surface properties and as possible allow high tear length.
Erfindungsgemäß wurde die Aufgabe dadurch gelöst, dass die Stoffsuspension zumindest DIP und einen Anteil an chemithermomechanischen Fasern enthält. Diese chemithermomechanischen Fasern werden auch als Hochausbeutefasern bezeichnet und zeigen gegenüber bisher eingesetzten Fasern eine vorteilhafte Kombination von optischen Eigenschaften und Festigkeiten.According to the invention was solved the task by that the pulp suspension contains at least DIP and a proportion of chemithermomechanical Contains fibers. These chemithermomechanical fibers are also called high yield fibers designated and show opposite previously used fibers an advantageous combination of optical Properties and strengths.
Die Hochausbeutefasern sind bereits bei niedrigem Mahlgrad und damit auch geringerem Aufwand an Mahlenergie in der Lage, eine gute Bindung an benachbarte Fasern aufzubauen, so dass ein relativ geringer Anteil an Hochausbeutefasern die erforderliche Reißfestigkeit auch bei einem hohen Anteil an DIP gewährleisten kann.The High yield fibers are already at a low degree of grinding and thus also lower the amount of grinding energy capable of a good bond to build adjacent fibers, so that a relatively small proportion on high-yielding fibers the required tear resistance even at a ensure a high proportion of DIP can.
Durch eine Bleichbehandlung der Hochausbeutefasern verbessern sich die Fasereigenschaften, insbesondere hinsichtlich Weißgrad erheblich. Mit der Bleichbehandlung steigen aber auch die Reißlängen und damit die Reißfestigkeit.By a bleaching treatment of the high yield fibers improves the Fiber properties, especially with regard to whiteness significantly. With the bleaching treatment but also increase the breaking lengths and thus the tear resistance.
Der gebleichte Hochausbeutefaserstoff verbessert wegen seines hohen Bulks und der hohen Weiße die Eigenschaften einer aus der Stoffsuspension hergestellten Faserstoffbahn derart, dass auch ein hoher, insbesondere zwischen 55 und 95%, vorzugsweise zwischen 70 und 85% liegender DIP-Anteil in der Stoffsuspension für Magazinpapiere möglich ist.Of the Bleached high-yield pulp improves due to its high Bulks and the high whites the Properties of a fibrous web made from the stock suspension such that a high, in particular between 55 and 95%, preferably between 70 and 85% DIP content in the stock suspension for magazine papers possible is.
Der Anteil der verschiedenen Faserstoffe in der Stoffsuspension bezieht sich hier auf ihren Trockengewichtsanteil am gesamten Faserstoff der Suspension.Of the Share of different pulp in the stock suspension refers here on their dry weight content of the entire pulp the suspension.
Um den Kostenvorteil des DIP maximal nutzen zu können, sollte neben DIP und dem chemithermomechanischen Faserstoff kein anderer Faserstoff in der Stoffsuspension vorhanden sein.Around To maximize the cost advantage of the DIP, DIP and the chemithermomechanical pulp no other pulp in the pulp suspension be present.
In Abhängigkeit von den Anforderungen an die Faserstoffbahn, aber auch der Qualität und dem Preis der zur Verfügung stehenden Faserstoffe kann es jedoch ebenso vorteilhaft sein, wenn neben DIP und dem chemithermomechanischen Faserstoff noch wenigstens ein anderer Faserstoff in der Stoffsuspension vorhanden ist.In dependence from the requirements of the fibrous web, but also the quality and the Price of available However, standing fibrous materials, it may also be advantageous if at least in addition to DIP and the chemithermomechanical pulp another pulp is present in the pulp suspension.
Dabei können diese anderen Faserstoffe insbesondere von GW, TMP oder Zellstoff oder einer Mischung davon gebildet werden.there can these other fibers, in particular GW, TMP or pulp or a mixture thereof.
Damit die höheren Kosten beim Einsatz von Zellstoff und/oder die relativ geringe Festigkeit von GW und TMP-Fasern das Produkt nicht zu stark beeinträchtigen, sollte der Anteil des anderen Faserstoffes höchstens 20, vorzugsweise höchstens 10% betragen.In order to the higher ones Cost of using pulp and / or the relatively low strength GW and TMP fibers do not affect the product too much, the proportion of the other pulp should be at most 20, preferably at most 10%.
Als chemithermomechanische Fasern eignet sich insbesondere BCTMP, CTMP oder APMP. Charakteristisch für diese Hochausbeutefaserstoffe sind die relativ geringen Kosten und die relativ hohe Festigkeit sowie die guten optischen Eigenschaften. Als CTMP versteht man Chemi-Thermo-Mechanical-Pulp, d. h. Refinerholzstoff unter Anwendung von Druck und Wärme sowie Chemikalieneinwirkung.As chemithermomechanical fibers are particularly suitable BCTMP, CTMP or APMP. Characteristic of these high-yield fibers are the relatively low cost and the relatively high strength so like the good optical properties. CTMP is understood to mean Chemi-Thermo-Mechanical Pulp, ie refining wood using pressure and heat as well as chemical action.
BCTMP sind gebleichte CTMP-Fasern und APMP steht für Alkaline-Peroxide-Mechanical-Pulp, d. h. Refinerholzstoff mit vorhergehender alkalischer Peroxidbehandlung zur verbesserten Zerfaserung und Faserstoffqualität.BCTMP are bleached CTMP fibers and APMP stands for Alkaline Peroxides Mechanical Pulp, d. H. Refining wood with previous alkaline peroxide treatment for improved defibration and pulp quality.
Für die meisten Magazinpapiere lassen sich optimale Eigenschaften bei einem Anteil an chemithermomechanischem Faserstoff zwischen 5 und 45, insbesondere zwischen 10 und 25% erzielen.For the most Magazine papers can be optimal properties in one share chemithermomechanical pulp between 5 and 45, in particular between 10 and 25%.
Nachfolgend soll die Erfindung an mehreren Ausführungsbeispiel näher erläutert werden.following the invention will be explained in more detail in several embodiments.
In allen Fällen werden die chemithermomechanischen Hochausbeutefaserstoffe aus feinem Laubholz, wie Eukalyptus, Espe oder Zitterpappel erzeugt.In all cases The chemithermomechanical high-yield fibers are made of fine Hardwood, such as eucalyptus, aspen or aspen produces.
Zur Herstellung von superkalandrierten Magazinpapieren sollten die Hochausbeutefasern gemahlen werden.to Production of supercalendered magazine papers should be the high yield fibers be ground.
Untersuchungen haben gezeigt, dass sich die optischen Eigenschaften, insbesondere der Weißgrad mit zunehmendem DIP-Anteil verschlechtern, wobei jedoch durch die Wirkung der chemithermomechanischen Fasern bei Magazinpapieren ein DIP-Anteil bis 90% möglich ist.investigations have shown that the optical properties, in particular the whiteness with deteriorate as the DIP content increases, however, due to the effect the chemithermomechanical fibers in magazine papers a DIP fraction up to 90% possible is.
Dabei lässt sich wegen der Bleiche die Optik durch den Einsatz von BCTMP noch verbessern.there let yourself because of the bleaching the optics through the use of BCTMP still improve.
Auf den Bulk wirkt sich eine Veränderung des DIP-Anteils nur unwesentlich aus.On the bulk affects a change of the DIP share is insignificant.
Allerdings führt eine Verminderung des DIP-Anteils auch zu einer Verringerung der Reißfestigkeit, weshalb der DIP-Anteil über 55% liegen sollte.Indeed leads one Reduction of the DIP content also leads to a reduction in tear strength, which is why the DIP share over Should be 55%.
Aus einer Mischung von 5–45% des chemithermomechanischen Faserstoffs und 55– 95% DIP, bezogen auf das Trockengewicht des gesamten Faserstoffs, lässt sich mit Wasser eine Faserstoffsuspension zubereiten, die für die Herstellung von Faserstoffbahnen, insbesondere Magazinpapier sehr gut geeignet ist.Out a mix of 5-45% chemithermomechanical pulp and 55-95% DIP by dry weight of the entire pulp leaves to prepare a pulp suspension with water, which is suitable for the production of fibrous webs, especially magazine paper very well suited is.
Bei
einer Mischung von DIP und APMP-Fasern haben sich dabei folgende
Werte ergeben:
Die Nachteile des DIP hinsichtlich Weißgrad werden von dem Hochausbeutefaserstoff kompensiert, so dass ein hoher DIP-Anteil ermöglicht wird. Im Ergebnis ergeben sich erhebliche Kosteneinsparungen.The Disadvantages of DIP in terms of whiteness are from the high yield fiber compensated, so that a high DIP share is made possible. As a result, result Significant cost savings.
Zur Optimierung der Eigenschaften der Faserstoffbahn kann es jedoch auch von Vorteil sein, noch einen weiteren Faserstoff, insbesondere Zellstoff, GW oder TMP hinzuzufügen. Diese können die optischen Eigenschaften noch weiter verbessern. Darüber hinaus erhöht der Zellstoff die Reißfestigkeit, aber auch die Kosten.to However, optimization of the properties of the fibrous web can do it also be advantageous, yet another pulp, in particular Add pulp, GW or TMP. these can improve the optical properties even further. Furthermore elevated the pulp's tear resistance, but also the costs.
Beispielhaft kann die Stoffsuspension so aus 55% DIP, 35% chemithermomechanischen Fasern und 10% Zellstoff oder aber aus 60% DIP, 20% chemithermomechanischen Fasern und 20% GW/TMP bestehen.exemplary The pulp suspension can be made from 55% DIP, 35% chemithermomechanical Fibers and 10% pulp or else 60% DIP, 20% chemithermomechanical Fibers and 20% GW / TMP exist.
