Description

Verfahren zur Verreibung und kolloidalen Verteilung von festen Körpern in Walzenstühlen . oder Reibbarrenmühlen Es ist bereits vorgeschlagen worden, die Graphitsuspensionen in Walzenstühlen oder Reibbarrenmühlen unter Verwendung möglichst hohen Druckes. zu verneiblen.Process for trituration and colloidal distribution of solids in roller mills. or grating bar mills It has already been suggested that Graphite suspensions in roller mills or friction bar mills using if possible high pressure. to hide.

Derartige hohle Drücke, die etwa i bis 2 kg auf den Quadratmillimeter betragen, sind besonders in Verbindung mit einer flächenmäßigen Verreibung biet anderem Mahlgut, wie Farbpigmenten, Tonen o. dgl., ohne die Gegenwart von Graphit nicht anwendbar, da die Verreibwalzen sofort festbrennen würden.Such hollow pressures, about 1 to 2 kg per square millimeter are, in particular, in connection with an extensive trituration other regrind, such as color pigments, clays or the like, without the presence of graphite not applicable, as the distribution rollers would burn immediately.

Es hat sich. nun gezeigt, daß man leinet bisher nicht erreichbare feine sind sehr rasche, kolloidal anzuspnechiende Verteilung beliebiger fester Stoffe erhält, wenn man Ruß und anderen, praktischerweise dunkelfarbigien. Pigmenten zur Herstellung von Druckfarben, Tonerden für die Bleistiftindustrie, Ocker für Rostschutzfarben ioder ähnlichen festen Körpern, wie pulverisierten Metallen, je nach Bedarf mehr loder weniger Graphit hinzufügt, das Mahlgut sozusagen schmiert, und alsdann die Mischung in Walzenstühlen -oder Reibbarremnühlen unter Anwendung flächenmäßiger Verreibung und einem Überdruck von etwa i bis 2 kg auf den Quadratmillimeter mit dem entsprechenden Bindemittel, wie Leinöl, Wasser, Glycerin. usw" verreibt.It has. It has now been shown that one can obtain fine, so far not attainable, very rapid, colloidally appealing distribution of any solid matter when one receives soot and other, practically dark colors. Adds pigments for the production of printing inks, clays for pencil industry, ocher for anticorrosion paints i or similar solid bodies, such as powdered metals as required more loder less graphite, lubricates it were the ground material, and then the mixture in roller mills -or- Reibbarremnühlen using areal mull and an overpressure of about 1 to 2 kg per square millimeter with the appropriate binding agent, such as linseed oil, water, glycerine. etc. "rubbed.

# Durch Anwesenheit des Graphits wird trotz des starken Überdruckes lein Festbrennen der Walzen vermieden. Wähnend bei den Druckfarben, den Tonerden für die Bleistiftindustrie oder den Rostschutzfarben der Graphit in der Masse verbleiben kann oder verbleiben muß, so besteht bei deiner kolloiden Metallsuspension leicht die Möglichkeit, beispielsweise mittels magnetischer Einwirkung durch Trennung der Metallteilchen von dem Graphit den letzteren wieder zu ientfernen.# Due to the presence of graphite, despite the strong overpressure Avoid burning of the rollers. Mentioning the printing inks, the clays for the pencil industry or for anti-rust paints, the graphite remains in the mass can or must remain, your colloidal metal suspension easily exists the possibility of, for example, by means of magnetic action by separating the Metal particles from the graphite to remove the latter again.

Die praktische Durchführung dies Verfahrens geschieht folgendermaßen: Ein Farbpigment, beispielsweise Ruß, wird mit den derforderlichen Bindemitteln, meistens Leinöl und Biturnen, versetzt, bis die gewünschte Konsistenz der Farbie eintritt.The practical implementation of this procedure is carried out as follows: A color pigment, for example carbon black, is combined with the necessary binders mostly linseed oil and biturns, mixed until the desired consistency of the color entry.

Das Mischungsverhältnis von Ruß, Biturnen und Leinöl ist an sich Schwankungen unterworfen und richtet sich-nach den zur Verwendung kommenden Qualitäten des R@ohsboffes und dem Verwendungszweck der Druckfarbe.The mixing ratio of soot, biturns and linseed oil is inherently fluctuations subject to and depends on the qualities of the R @ ohsboff to be used and the intended use of the ink.

Dem Gemisch wird nun io°/o seines Gesamtgewichtes trockener Graphit beigegeben und alsdann die Masse einmal, allerhöchstens zweimal auf einer Einwalze oder deiner Mehrwalze mit flächenmäßiger Verreibung -und einem Überdruck von mindestens i bis 2 kg auf den Quadratmillimieüer verrieben.10% of its total weight of dry graphite is then added to the mixture and then the mass is rubbed once, at most twice on a single roller or your multi-roller with extensive grinding - and an overpressure of at least 1 to 2 kg on the square millimeter.

Während nach den bisherigen Verfahren ohne Graphit die Farben bis zu achtmal durch große Mehrwalzenstühle bis zu ihrer Fertigstellung hindurchgeleitet werden mußten, ist meist schon bei einem einmaligen Durchgang nach dem hier geschilderten Beispiel die Farbe fertiazestellt. - While in the previous process without graphite the colors had to be passed through large multi-roller mills up to eight times before they were finished, the color is usually produced in a single pass according to the example described here. -
