Description

Verfahren zur Herstellung von Leimpulver Knochen- oder Hautleimbrühen, die meist 500/0 Wasser enthalten, werden gewöhnlich mittels eines Warmluftstromes bis zu einem Wassergehalt von etwa 12(/o getrocknet, worauf die Masse z, B. in Formen gegossen wird. Zur Gewinnung von Leimpulver muß der Leim dann noch mechanisch zerkleinert werden. Man hat auch schon vorgeschlagen, Leimpulver durch Abschaben der Leimlösung von einer drehenden Trommel unter Vakuum herzustellen; es sind hierfür jedoch teuere und umfangreiche Anlagen notwendig.Process for the production of glue powder, bone or hide glue broth, which usually contain 500/0 water, are usually by means of a stream of warm air to a water content of about 12 (/ o dried, after which the mass, e.g. in molds is poured. To obtain glue powder, the glue then has to be mechanically comminuted will. It has also been suggested to use glue powder by scraping off the glue solution manufacture from a rotating drum under vacuum; however, they are expensive for this and extensive systems are necessary.

Es wurde ein einfaches und wirtschaftliches Verfahren zur Herstellung von hochwertigem, fast farblosem Leimpulver aus wäßrigen Leimlösungen ohne Anwendung mechanischer Zerkleinerungsvorrichtungen gefunden. Das Verfahren besteht im wesentlichen darin, daß die Leimlösung mit organischen Lösungsmitteln, vornehmlich Perchloräthylen, vermischt und unter starkem Rühren so lange destilliert wird, bis praktisch kein Wasser mehr übergeht, worauf das restliche Lösungsmittel entfernt wird, z. B. mittels Vakuum, Warmluft, gespannten Wasserdampfes o. dgl. Überraschenderweise fällt dabei ein mehr oder minder feinkörniges Leimpulver von praktisch weißer Farbe an, welches sich leicht in Wasser löst. Das Pulver kann, da es sehr spröde ist, durch Mahlen noch weiter verfeinert werden.It became a simple and economical method of manufacture of high-quality, almost colorless glue powder from aqueous glue solutions without application mechanical crushers found. The procedure essentially consists that the glue solution with organic solvents, primarily perchlorethylene, mixed and distilled with vigorous stirring until practically none More water passes over, whereupon the remaining solvent is removed, e.g. B. by means of Vacuum, warm air, pressurized steam or the like. Surprisingly, this falls a more or less fine-grained glue powder of practically white color, which easily dissolves in water. The powder can, as it is very brittle, by grinding can be further refined.
