Buntpapier-, Tapetenfabrikation u. dgl.Colored paper, wallpaper production and the like.
Patentirt im Deutschen Reiche vom 26. Oktober igoo ab.Patented igoo in the German Empire from October 26th.
Es ist eine bekannte Thatsache, dafs mit den Abwässern der Chromopapier-, Chromopappen-, Buntpapier- und Tapetenfabrikation grofse Mengen werthvoller Farbstoffe durch das Waschen der Färbe- oder Druckmaschinen der farbauftragenden Filze und Transportgefäfse u. dgl. den Schleusen und Flufsläufen zugeführt werden, was einmal einen nennenswerthen Verlust für den Fabrikanten, das andere Mal eine unwesentliche Verunreinigung der Wasserläufe bedeutet.It is a well-known fact that with the effluents of the chromopaper, chromopaper, Colored paper and wallpaper manufacture large quantities of valuable dyes by washing the dyeing or printing machines the paint-applying felts and transport vessels and the like, the sluices and rivers which was once a noteworthy loss for the manufacturer, the other times it means insignificant pollution of the watercourses.
Vorliegende Erfindung betrifft ein Verfahren zur Wiedergewinnung der Farbstoffe aus den. Abwässern genannter Fabrikationszweige. Nach diesem Verfahren wird die Farbe von dem Spülwasser in äufserst einfacher Weise so abgesondert, dafs sie sich zum Streichen der Papiere und Pappen, mindestens aber zum Grundiren derselben verwenden läfst.The present invention relates to a method for recovering the dyes from. Sewage of the manufacturing branches mentioned. After this procedure, the color of the Rinse water separated in an extremely simple manner in such a way that it is suitable for brushing the Paper and cardboard, but at least for priming them, can be used.
Bekanntlich werden bei der Herstellung von Kunstdruck- und Chromopapieren, Chromopappen und Buntpapieren, sowie auch Tapeten alle Farben entweder mit thierischem Leim, Casein, Lactarin, Pflanzenleim oder beliebigen anderen Klebstoffen vermischt und somit bindefähig gemacht. Alle diese Farbenbindemittel müssen aüfser der ihnen innewohnenden Bindefähigkeit noch die Eigenschaft der Viscosität besitzen, vermittels welcher die dem Bindemittel zugesetzten Farben schwebend erhalten werden.It is well known that in the production of art print and chromo papers, chromo boards are used and colored papers, as well as wallpapers of all colors either with animal glue, casein, lactarin, vegetable glue or any other color mixed with other adhesives and thus made bindable. All of these paint binders In addition to their inherent binding capacity, they must also have the property of viscosity own, by means of which the colors added to the binder are kept floating will.
Während der thierische Leim diese Eigenschaft der Viscosität von vornherein besitzt, und zwar umsomehr, je reiner das zu seiner Lösung verwendete Wasser war, erhalten Casein und Pflanzenleime aller Art ihre viscose Eigenschaft indirect, und zwar durch Zusätze bekannter Lösungsmittel.While animal glue possesses this property of viscosity from the outset, and the more pure the water used to dissolve it, the more casein is obtained and vegetable glues of all kinds their viscous property indirectly, through additives that are well known Solvent.
Werden nun die jeweilig angewendeten Farbenbindemittel mit geeigneten Mitteln, wie z. B. mit Thonerdesalzen, Aluminaten, Chromsalzen, Aldehyden, Alkoholen, Chlorcalcium, Chlorbaryum u. dgl., versetzt, welche Mittel ein »Coaguliren« oder Gerinnen herbeiführen, so wird die Eigenschaft der Viscosität theilweise oder ganz aufgehoben und die so behandelten Farbstoffe neigen zum Fällen, wodurch ihre Trennung von dem überschüssigen Wasser herbeigeführt wird und dieses einfach durch Decantiren von den Farbstoffen getrennt werden kann.Are now the color binders used in each case with suitable means, such as z. B. with alumina salts, aluminates, chromium salts, aldehydes, alcohols, calcium chloride, Chlorobaryum and the like, added, which agents cause "coagulation" or clotting, so the property of viscosity is partly or wholly abolished, and those so treated Dyes tend to precipitate, causing them to separate from the excess water and this is easy can be separated from the dyes by decanting.
Die so gewonnenen. Farben finden, nachdem sie wieder mit Bindemitteln angerührt sind, weitere Verwendung in der Fabrikation bezw. Herstellung von Streich- und Druckfarben.The ones won in this way. Find colors after they have been mixed with binders again, further use in manufacture respectively. Manufacture of coating and printing inks.

Verfahren zur Wiedergewinnung der Farbstoffe aus den Abwässern der Kunstdruck-, Chromopapier-, Chromopappen-, Buntpapier- und Tapetenfabrikation, dadurch gekennzeichnet, dafs man die die Farbstoffe in Suspension haltenden Bindemittel durch Zusatz von Fällungsmitteln niederschlägt. Patent claim:
Process for the recovery of the dyes from the wastewater from art print, chromo paper, chromo cardboard, colored paper and wallpaper production, characterized in that the binders holding the dyes in suspension are precipitated by adding precipitants.
