Description
AUSGEGEBEN AM 7. JANUAR 1920ISSUED ON JANUARY 7, 1920
Bei allen bisher bekannten Verfahren, welche eine Mischung von Harz, Kasein u, dgl. und Wasserglas zum Leimen von Papier durch Fällung des Gemisches durch besondere saure Fällmittel verwenden, wird die Ausfällung erst im Holländer- vorgenommen. Die Absonderung und Ausscheidung von Kieselsäure aus dem Wasserglas vor dem Einbringen in den Holländer wird sorgfältigstIn all previously known processes, which are a mixture of resin, casein u, the like. And water glass for glueing paper by precipitating the mixture by using special acidic precipitants, the Precipitation only made in the Dutch. The secretion and excretion of silica from the water glass before it is placed in the Hollander is very carefully
ίο vermieden. Die Ausfällung im Holländer hat aber den Nachteil, daß es bei der Fällung in der Stoffmasse großer Leimmengen bedarf, um eine genügende Leimwirkung zu erzielen. Infolge dieses notwendigen Leim Überschusses fließt unvermeidlich Leimsubstanz in nicht unbeträchtlicher Menge in das Siebwasser ab, so daß Verluste an wertvollen Leimsubstanzen entstehen.ίο avoided. The precipitate in the Dutch has but the disadvantage that large amounts of glue are required for precipitation in the mass of the substance, to achieve a sufficient glue effect. As a result of this necessary glue excess Inevitably, a not inconsiderable amount of glue substance flows off into the white water, so that losses of valuable glue substances occur.

This creates the glue-silicon-alumina connection even before touching the pa-
»5 pierstoffe gebildet und verleiht dem Papier einen besonders wertvollen Charakter. Glanz, Griffigkeit und Völligkeit werden erhöht, was wahrscheinlich durch das Verschmieren, der Papierfaser mit dem Siliziumleim verursacht wird. Die bedeutende Bindung der Füllstoffe ist eine weitere günstige Erscheinung, welche das Verfahren auszeichnet: Außerdem werden die Siebwässerverluste bedeutend vermindert. Insbesondere eignet sich das Abfahren zur Herstellung von Wertpapieren.»5 paper fabrics are formed and gives the paper a particularly valuable character. Shine, grip and fullness are increased what probably caused by smearing the paper fiber with the silicon glue will. The significant binding of the fillers is another beneficial phenomenon which the process distinguishes itself: In addition, the white water losses are significantly reduced. In particular, the shutdown is suitable for Manufacture of securities.
Bei Ausübung des- Verfahrens stellt man sich z. B. in bekannter Weise eine Lösung von tierischem Leim im Verhältnis von etwa ι Teil Leim zu 6 Teilen Wasser her und vermischt die noch warme Lösung mit besonders hergestellter Wasserglaslösung von 1 Teil Wasserglas von etwa 38° Be und 8 Teilen Wasser. Nach Abkühlung setzt man dem noch flüssigen Gemisch beispielsweise eine Lösung von schwefelsaurer Tonerde unter kräftiger Durcharbeitung hinzu, bis ein erheblicher Teil oder die ganze Menge der Leim-Silizium-Verbindung ausgefällt ist. Es ist vorteilhaft, nicht die vollständige Ausfällung vorzunehmen, jedenfalls ist zu vermeiden, daß ein Überschuß des Fällungsmittels angewendet wird.When exercising the procedure, you z. B. in a known manner a solution of animal glue in the ratio of about ι part glue to 6 parts water and mixed the still warm solution with specially prepared water glass solution of 1 part Water glass of about 38 ° Be and 8 parts of water. After cooling down, you can still use it liquid mixture, for example, a solution of sulfuric alumina under vigorous Working through adds up to a significant part or all of the glue-silicon bond has failed. It is advantageous not to carry out the complete precipitation, In any case, it should be avoided that an excess of the precipitating agent is used will.
In entsprechender Weise kann man mit Gemischen von Leimlösung mit Stärke, Kasein, Harz, Wachs, Humussäuren usw. in zweckmäßiger Zubereitung verfahren oder solche kolloidalen Leimungsmaterialien allein zur Verarbeitung bringen. Immer wird die besondere Herstellung des Leimgutes vor dem Eintragen zur Papiermasse das wesentlichste 6p sein müssen.In a corresponding way, you can use mixtures of glue solution with starch, casein, Resin, wax, humic acids, etc. proceed in appropriate preparation or such colloidal sizing materials alone Bring processing. Always the special production of the glue before the Entering to the pulp the most essential must be 6p.
Nach dem Zumischen des Leimmaterials zum Holländerstoff wird derselbe mit Tonerdesalzlösungen usw. in üblicher Weise bis zur schwachsauren Reaktion versetzt, falls nicht bereits saure Reaktion beim Eintragen und nach erfolgter Durchmischung vorliegt.After adding the glue material to the Dutch fabric, it is made with alumina salt solutions etc. in the usual way up to the weakly acidic reaction, if not already acidic reaction when entering and is present after mixing has taken place.
Bei der Herstellung von haltbarem Papierleim ist es vorteilhaft, die fäulniswidrigen Substanzen dem PapierleimwasserglasgemischWhen producing durable paper glue, it is advantageous to use the non-rot Substances in the paper sizing waterglass mixture

zuzusetzen und erst dann die Ausfällung vorzunehmen. add and only then carry out the precipitation.
In gleicher Weise ist es zweckmäßig, Füllstoffe. Farben usw. vor der Ausfällung beizumischen, da auf diesem Wege eine vollkommene Bindung der wertvollen Materialien im Papierbrei erreichbar ist und vorzügliche Verteilung erzielt werden kann.In the same way, it is useful to use fillers. To mix in colors etc. before the precipitation, because in this way a perfect binding of the valuable materials in the Paper pulp is achievable and excellent distribution can be achieved.
