Description

Verfahren zur Herstellung eines Kittes oder Bindestoffes aus Sulfitablauge. Bei den mannigfachen: Versuchen zur Verwertung der Sulfitablauge ist es bereits gelungen, aus der Ablauge ein Anstrich- und Imprägnierungsmittel herzustellen, indem man die neutralisierte und einbggedickte Ablauge mit einer Lösung von Asphalt in Teer und Teeröl sowie mit Wasser anrührt, wobei man ein mit Wasser vollkommen. emulgierbares Produkt erhält, wie es für Imprägnierungszwecke u. dgl. erforderlich ist.Process for the production of a putty or binding material from sulphite waste liquor. With the manifold: Attempts to utilize the sulphite waste liquor it is already succeeded in producing a paint and impregnation agent from the waste liquor by the neutralized and concentrated waste liquor with a solution of asphalt in Tar and tar oil as well as mixed with water, one with water completely. emulsifiable Product received as required for impregnation purposes and the like.

Dagegen hatten; die Versuche, aus Suffitablauge einen brauchbaren Kitt oder Klebestoff herzustellen, bisher zu keinem Erfolge geführt, weil die vorgeschlagenen Verfahren weder ein, Erzeugnis von genügender Klebkraft lieferten noch einfach und wirtschaftlich: genug arbeiteten. Verwendet man, wie versucht worden ist, Sulfitablauge allein und dampft sie bis zur Trockne ein, so erfordert dies bei verhältnismäßig :großem Brennstoffverbrauch besondere, das Verfahren erschwerende Vorrichtungen, um das Anbrennen zu verhindern. Überdies ist 'die so hergestellte Masse nicht haltbar, sondern büßt ihre Klebekraft bald ein, da sie hygroskopisch ist und aus. der Luft Wasser anzieht.Had against it; the attempts to make a usable one from Suffitablauge Producing putty or glue has so far not led to any success, because the proposed ones The process neither produced a product with sufficient adhesive strength nor was it simple and economical: worked enough. If, as has been tried, sulphite waste liquor is used alone and if it evaporates to dryness, then this requires proportionally : high fuel consumption special devices that complicate the process, to prevent scorching. Moreover, the mass produced in this way is not durable, but soon loses its adhesive power because it is hygroscopic and off. the air Attracts water.

Ferner wurde der Vorschlag gemacht, ein besseres Erzeugnis herzustellen, indem man der eingedickten: Ablauge Kalkbrei zusetzt, wodurch man zwar ein gegen, Feuchtigkeit beständiges Klebemittel erhält, das aber nur in ganz dünner Schichte angewendet werden kann, da es sonst rissig wird. . .A proposal was also made to make a better product, by adding lime paste to the thickened waste liquor, whereby one against, Moisture-resistant adhesive is given, but only in a very thin layer can be used, otherwise it will crack. . .

Gegenüber diesem Stande der Technik ist der Fortschritt des erfindungsgemäß hergestellten Klebemittels darin zu erblicken, daß es auf einfache Weise gewonnen werden kann und die geschilderten Nachteile der früher verwendeten Produkte nicht' aufweist, sondern allen: Anforderungen entspricht, die an ein Bindemittel ,gestellt werden. Es ist weder hygroskopisch, noch bedarf es zu seiner Herstellung übermäßiger Brennstoffmengen, noch ist es in seiner Anwendung auf geringe Schichtdicke beschränkt.Compared to this prior art, the progress of the invention is manufactured adhesive can be seen in the fact that it is obtained in a simple manner and the disadvantages of the previously used products are not ' but all: meets the requirements placed on a binding agent will. It is neither hygroscopic nor does it require excessive amounts to be produced Fuel quantities, nor is it limited in its application to a small layer thickness.

Das Verfahren: besteht darin; daß man Sulfitablauge zunächst mit so viel gelöschtem Kalk versetzt, Abis alle in ihr enthaltenen anorganischen; und organischen Säuren abgestumpft sind, worauf man die Flüssigkeit von dem entstandenen Niederschlage trennt und erstere so lange eindampft, bis eine aus der kochenden Masse entnommene Probe beim Erkalten an der Luft sofort erstarrt. Nun wird der weitgehend entwässerten, kochenden Masse,so viel schweres Mineralöl beigemischt, daß -eine neuerdings entnommene Probe nach dem Erkalten an der Luft noch flüssig bleibt. Nach -dem Abkühlenlassen des Gemenges erhält man eine dicke Flüssigkeit von starker Klebkraft, die für die Brikettierung von Brennstoffen, Erzen usw. sowie für andere technische Zwecke vorzüglich geeignet ist.The procedure: consists in; that one sulphite liquor initially with so much slaked lime added, Abis all the inorganic contained in it; and organic Acids are blunted, whereupon the liquid from the resulting precipitate separates and the former evaporates until one is removed from the boiling mass Sample solidifies immediately on cooling in air. Now the largely drained, boiling mass, so much heavy mineral oil mixed in that one recently removed Sample remains liquid after cooling in air. After letting it cool down the mixture gives a thick liquid of strong Bond strength, those for the briquetting of fuels, ores, etc. as well as for other technical Purposes is excellently suited.

PATENTANSPRUCH: Verfahren zur Herstellung eines Kittes oder Bindestoffes aus Sulfitablauge, da-,durch gekennzeichnet, daß die Ablauge mit Kalk neutralisiert, der Niederschlag entfernt, die Flüssigkeit bis zum Erstarren einer Probe an der Luft entwässert und schließlich noch kochend mit so viel schwerem Mineralöl versetzt wird, daß eine neuerdings entnommene Probe nach dem Erkalten an 'der Luft noch flüssig bleibt.PATENT CLAIM: Process for the production of a putty or binding material from sulphite waste liquor, characterized in that the waste liquor is neutralized with lime, the precipitate removes the liquid until a sample solidifies on the Air dehydrated and finally mixed with so much heavy mineral oil while still boiling that a recently taken sample is still liquid after cooling in the air remain.
