Description

Herstellung von Granalien aus Bleimennige und/oder -glätte Die Erfindung betrifft ein Verfahren zur Herstellung von Granalien aus pulverförmiger Bleimennige und/oder -glätte durch Granulierung unter Beimischung geeigneter Zusätze. An und für sich ist die Herstellung von Granalien grundsätzlich bekannt, jedoch ist eine solche Herstellung bei Bleimennige und/oder -glätte bisher nicht angewendet worden, und zwar vor allem mit Rücksicht auf die äußerst große Feinkörnigkeit der Bleioxyde. Die Feinkörnigkeit dieser Oxyde ist gekennzeichnet durch eine mittlere Korngröße von 5 bis 20 #t.Manufacture of red lead and / or black lead granules The invention relates to a process for the production of granules from powdered red lead and / or smoothness by granulation with admixture of suitable additives. To and in itself the production of granules is known in principle, but one is such production has not yet been used for red lead and / or smoothness, especially with regard to the extremely fine grain size of lead oxides. The fine grain of these oxides is characterized by a medium grain size from 5 to 20 #t.

Andererseits ist aber die Weiterverarbeitung von Bleimennige und -glätte sehr viel günstiger, wenn diese Stoffe in Granalienform vorliegen.On the other hand, there is the further processing of red lead and smoothness Much cheaper if these substances are in the form of granules.

Der Erfindung liegt die Aufgabe zugrunde, die an sich bekannten Verfahren zur Herstellung von Granalien bei Bleimennige und/oder -glätte anzuwenden und dabei diese Verfahren so zu modifizieren, daß sie speziell für diese Stoffe geeignet sind.The invention is based on the task of the methods known per se to use for the production of granules in red lead and / or smoothness and thereby to modify these procedures so that they are specifically suitable for these substances.

Diese Aufgabe wird dadurch gelöst, daß erfindungsgemäß Bleimennige und/oder -glätte und ständiger Rüttel- und Wurfbewegung mit 5- bis 15o/oigem Zusatz an bekannten Netz-, Binde- und Härtungsmitteln auf Temperaturen bis zu 300° erhitzt und nach dem Abkühlen gesiebt werden.This object is achieved in that, according to the invention, red lead and / or smoothness and constant shaking and throwing motion with 5 to 15% additive heated to temperatures of up to 300 ° on known wetting, binding and hardening agents and sifted after cooling.

Auf die vorgeschriebene Weise lassen sich überraschenderweise aus der feinkörnigen Bleimennige und/oder -glätte zuverlässig die gewünschten Granalien herstellen.Surprisingly, the prescribed way can be omitted the fine-grained red lead and / or smoothness reliably the desired granules produce.

Eine spezielle Ausführung des erfindungsgemäßen Verfahrens besteht darin, daß als Zusätze Natronwasserglas, Kaliwasserglas, mehrwertige Alkohole (Glycerin), Kunststoffdispersionen, z. B. aus Polyvinylchlorid/Acrylsäure, Polystyrol usw. sowie auch Sulfitablauge und Melasseabfälle, gegebenenfalls in Kombination mit handelsüblichen Netzmitteln, verwendet werden.There is a special embodiment of the method according to the invention in that, as additives, soda water glass, potassium water glass, polyvalent alcohols (glycerine), Plastic dispersions, e.g. B. made of polyvinyl chloride / acrylic acid, polystyrene, etc. as well also sulphite waste liquor and molasses waste, if necessary in combination with commercially available Wetting agents, can be used.

Gerade die vorgenannten Stoffe haben sich als ganz besonders wirksam für eine zuverlässige Durchführung des erfindungsgemäßen Verfahrens erwiesen.The aforementioned substances in particular have proven to be particularly effective Proven for a reliable implementation of the method according to the invention.

Die genannten Zusätze können in verdüster Form oder auch in Tropfenform oder auf einmal zugeführt werden, ohne daß dieses am Wesen der Erfindung etwas ändert.The additives mentioned can be in atomized form or in droplet form or be supplied all at once, without this changing anything in the essence of the invention.
