KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nachstehend beschriebenes Verfahren bezieht sich auf Verwerthung von Keratin oder verwandte Körper enthaltenden Stoffen, am besten von Abfällen, wie schlechtem Horn, Hufen, Klauen, Haaren und dergl., die sich mit geringen Kosten zu gut verwerthbaren Klebstoffen verarbeiten lassen.The process described below relates to the utilization of keratin or related products Substances containing the body, preferably waste, such as bad horn, hooves, Claws, hair and the like. Which can be converted into easily recyclable adhesives at low cost let process.
Solche Körper, wie Hörner, Klauen und Hufe, werden in Wasser von über ioo° gelöst; diese Lösung wird durch den Gerbstoff der Ablauge der Sulfitzellstofffabrikation gefällt. Ein Theil der genannten Abfälle wird nicht völlig durch Wasser gelöst; dieser wird durch verdünnte Natronlauge in Lösung gebracht und wie oben angegeben ausgefällt. Die entstandenen Gerbstoffverbindungen werden dann in Wasser mit wenig Soda gelöst und als Klebstoff benutzt.Such bodies as horns, claws, and hooves are dissolved in water of over 100 °; this solution is precipitated by the tanning agent of the waste liquor from the sulphite pulp manufacture. A Part of the waste mentioned is not completely dissolved by water; this is diluted by Brought sodium hydroxide solution and precipitated as indicated above. The resulting Tanning compounds are then dissolved in water with a little soda and used as glue used.
Bei der Fällung des Gerbstoffes unter Anwendung der Ablauge als solcher bleibt in der Mutterlauge aufser den nicht herausgefallenen stickstoffhaltigen Stoffen der gährungsfähige Körper der Sulfitablauge.When the tanning agent is precipitated using the waste liquor as such, the Mother liquor is fermentable apart from the nitrogenous substances that have not fallen out Body of the sulphite liquor.
In einem eisernen Kessel mit etwa 5 cbm Inhalt, welcher mit den nöthigen Armaturen und Mannlöchern zum Einfüllen und Entleeren und auch mit Vorrichtungen, um heifses Wasser und Dampf aus einem Dampfkessel hineinzupressen, versehen ist, befindet sich eine Auskleidung von Mauerwerk und Blei. In diesen Kessel werden Hornabfälle hineingeschüttet. Nach Verschliefsen des Kochers wird nun zunächst heifses Wasser in denselben hineingelassen und dieses, wenn nöthig, noch durch Dampf bis zur Temperatur von zweckmäfsig 110 bis 1400 erhitzt. Nach ungefähr 6 Stunden stärkeren Erhitzens enthält das Wasser mindestens 3 pCt. Horn gelöst. Durch einen Dampfstrom wird die richtige Temperatur aufrecht erhalten.In an iron kettle with a volume of about 5 cbm, which is provided with the necessary fittings and manholes for filling and emptying, and also with devices to press hot water and steam from a steam kettle, there is a lining of masonry and lead. Horn waste is poured into this cauldron. After Verschliefsen the digester first heifses water is then allowed into the same, and heated if necessary this, even by steam until the temperature of 110 to 140 zweckmäfsig 0th After about 6 hours of more intense heating, the water contains at least 3 pCt. Horn loosened. The correct temperature is maintained by a stream of steam.
Das Horn u. s. w. wird nun durch Wasser unter Erneuerung des letzteren im Kocher unter vollständiger Erweichung allmählich bis auf einen in Wasser unlöslichen schlammigen Rückstand aufgelöst, welcher, nachdem zweckmäfsig ein mehrmaliges Nachfüllen von Horn stattgefunden hat, zeitweilig aus dem Kessel entfernt wird. Dieser Schlamm, wenn er noch gröfsere Mengen ungelösten Horns enthält, bedarf einer besonderen Behandlung. Er wird entweder wieder zum Lösen in den Kocher gebracht oder durch verdünnte (2 pCt.) Natronlauge unter häufigem Umrühren und bei dickeren Massen unter Erwärmung gelöst. In gleicher Weise können auch die ursprünglich in Anwendung kommenden Körper, besonders solche, die in Wasser schwierig zu lösen sind, schnell gelöst werden.The horn and so on are now replaced by water while the latter is renewed in the cooker with complete softening gradually down to a sludge insoluble in water Residue dissolved, which after it was expedient to refill horn several times has taken place, is temporarily removed from the boiler. This mud, if he's still Contains large amounts of undissolved horn, requires special treatment. He will either put back in the stove to dissolve or diluted (2 pCt.) caustic soda dissolved with frequent stirring and, in the case of thick masses, with heating. In the same In this way, the bodies originally used, especially those which are difficult to dissolve in water are quickly dissolved.
In grofsen Bottichen wird nun weiter zu diesen Lösungen unter Zusatz von Säure oder säurehaltigen Körpern, z. B. schwefelsaurer Thonerde, Ablauge von der Sulfitzellstofffabrikation oder nur der Gerbstoff von derselben geschüttet, bis keine Fällung mehr entsteht. Die Menge der Ablauge richtet sich nach der Menge des gelösten Horns, ζ. B. auf ein Mafs einer 5 proc. Lösung in der Regel Y2 Mafs der gewöhnlichen Ablauge von 1,05 spec. Gewicht. Die in den Bottichen durch den Gerbstoff entstandene Fällung setzt sich schnell abIn large vats these solutions are then added with the addition of acid or acidic bodies, e.g. B. sulfuric alumina, waste liquor from the sulphite pulp production or only the tannin from the same poured until no more precipitation occurs. The amount of waste liquor depends on the amount of dissolved horn, ζ. B. on a measure of a 5 proc. Solution usually Y 2 measures of the ordinary waste liquor of 1.05 spec. Weight. The precipitate created in the vats by the tannin settles out quickly
