Description
Dicke Pappen, die auf dem gewöhnlichen Wege durch Zusammengautschen mehrerer Lagen auf der Pappenmaschine oder durch Schöpfen hergestellt sind, haben den Übelstand, daß sich die einzelnen Lagen besonders im feuchten Zustande leicht voneinander trennen. Dadurch wird die Widerstandsfähigkeit der Pappe beeinträchtigt und ihre Anwendbarkeit für manche Zwecke eingeschränkt.Thick cardboard on the ordinary Paths made by squeezing several layers together on the cardboard machine or by scooping have the disadvantage, that the individual layers separate easily from one another, especially when moist. This affects the strength of the cardboard and its applicability restricted for some purposes.
ίο Ferner können flüssige oder wasserlösliche Tränkungsmittel, die etwa das Wasserdichtoder Geschmeidigmachen der Pappe bewirken oder ihr sonstige Eigenschaften verleihen sollen, dem Stoff nicht beigemischt werden, weil sie auf dem Sieb und beim Abpressen zum größten Teil mit dem Wasser fortgehen. Auch lassen sich dicke Pappen nicht nachträglich gleichmäßig durchtränken.ίο They can also be liquid or water-soluble Impregnating agents which, for example, make the cardboard waterproof or pliable or are intended to give it other properties, are not added to the substance because most of them go away with the water on the sieve and when pressed. Even thick cardboard cannot be soaked evenly afterwards.
Das den Gegenstand der Erfindung bildende Verfahren macht es möglich, Pappen in jeder Dicke mit gleichmäßigem und festem Gefüge und mit den Tränkungsmitteln gleichmäßig durchtränkt herzustellen. ■ . ■The process forming the subject of the invention makes it possible to produce cardboard in any Thickness with an even and firm structure and even with the impregnating agents soaked to manufacture. ■. ■
Der im Holländer fein gemahlene, aus Hadem, Zellstoff, Holz, Leder oder anderen Fasern bestehende Stoff wird, soweit angängig, entwässert und darauf durch Kneten in einen gleichmäßigen steifen Brei verwandelt. Während des Knetens werden Bindemittel, wie Leim, Kasein, Dextrin u. dgl., in trockenem, fein gepulvertem Zustande beigemischt, die sich dann in der von den Fasern aufgesaugten Flüssigkeit entweder sofort oder durch Erwärmen oder durch Zusatz von Alkalien lösen. Es werden alsdann nach Bedarf auch Stoffe beigemischt, die das Bindemittel unlöslich machen, wie Chromalaun, Formaldehyd ο. dgl., oder der Ware eine besondere Biegsamkeit und Geschmeidigkeit verleihen, wie z. B. wasseranziehende Stoffe. Sämtliche Stoffe,- werden, soweit möglich, im trockenen, fein gepulverten Zustande dem Faserbrei beigemischt, um ihn so dickflüssig wie möglich zu erhalten.The finely ground in the Dutch, made of hadem, cellulose, wood, leather or other fibers Existing material is, as far as possible, dehydrated and then kneaded into one transformed into uniform stiff pulp. During kneading, binders such as Glue, casein, dextrin and the like, mixed in in a dry, finely powdered state, which then in the liquid absorbed by the fibers either immediately or by heating or dissolve by adding alkalis. Then there are also substances as required that make the binder insoluble, such as chrome alum, formaldehyde ο. like., or give the goods a particular flexibility and suppleness, such as. B. Hydrophilic Fabrics. All materials - are, as far as possible, finely powdered in the dry Mix with the pulp to make it as thick as possible.
Der fertige Brei wird durch Walzen zu Platten in gewünschter Stärke ausgerollt, die dann langsam getrocknet und schließlich noch emem starken Druck unter einer Presse ausgesetzt werden können. Das Gefüge der auf diese Weise erzeugten Papptafeln ist gleichmäßig. Bei der Herstellung gehen keine Stoffe verloren.The finished pulp is rolled out into sheets of the desired thickness by rolling then slowly dried and finally subjected to strong pressure under a press can be. The structure of the cardboard panels produced in this way is uniform. No substances are lost during production.
