Description

Gegenstand des Hauptpatents 960 324 ist ein Verfahren ziuir Herstellung· eines Pigmentes zum Anfärben von Pflanzenschutzmitteln.The subject of the main patent 960 324 is a Process for the production of a pigment for Coloring of plant protection products.

Die Erfindung stellt eine Variante des im Hauptpatent geschlidderten Verfahrens dar. Nach der Erfindtang im Rahmen des Hauptpatents werden die bei der Toneirdeherstellung durch alkalischen Aufschluß des Bauxits anfallenden eisenoxydhailtigen Rückstände, Rotschlamm genannt, entweder durch einen Schlämmprozeß verfeinert, die abgeschlämmten Feinstteile mit verdünnter Säure versetzt und abfiltriert oder nach dem Trocknen und Mahlen durch einen Sichtprozeß abgetrennt. Das erhaltene Pigment kann sowohl in Form einer Paste als auch in Gestalt eines Pulvers der Spritzbrühe beigefügt werden,The invention represents a variant of the method described in the main patent the inventions in the context of the main patent are those in clay manufacture alkaline digestion of the bauxite accumulating iron-oxide-containing residues, called red mud, either refined by a slurry process, the slurried fines with dilute acid added and filtered off or after drying and grinding through a Visual process separated. The pigment obtained can be in the form of a paste as well as in Form a powder are added to the spray mixture,

Im Laufe der Weiterentwicklung zeigte es sich, daß es möglich ist, das Herstellungsverfahren zu vereinfachen und gleichzeitig die Haftfähigkeit des Pigments dadurch zu steigern, daß man den nach dem Waschen, Trocknen, Mahlen und Windsichten erhaltenen Rotschlamm zwecks Einstellung des gewünschten pH-Wertes mit einem hydrolysierbaren Salz, beispielsweise Aluminiumsulfat, versetzt. Ebenfalls läßt sich der pH-Wert einer Paste durchIn the course of development, it was found that it is possible to simplify the production process while increasing the adhesiveness of the pigment characterized in that the red mud obtained after washing, drying, milling and air classification for the purpose of setting the desired p H -value one with a hydrolyzable salt, for example aluminum sulfate, added. Also, the pH value of a paste can be carried

Zusatz eines hydrolysierbaren Salzes bzw. einer Lösung desselben leichter einstellen.Adjust the addition of a hydrolyzable salt or a solution of the same more easily.

Beispielexample

Der Rotschlamm wird nach dem Waschen mit Wasser bis auf 5% Feuchtigkeit getrocknet. Nach dem Mahlen wird das Trockenmaterial einem Sichtprozeß unterworfen. 1000 kg der erhaltenen feinsten Anteile werden mit 20 kg Aluminiumsulfatpulver gründlich gemischt. Eine Suspension des so hergestellten Pulvers besitzt in einer Konzentration von 5 g pro 100 ml Wasser einen pH-Wert von 7,6. Das Pigment kann der Spritzbrühe usw. in einer Menge von etwa 1 bis 5 °/o beigefügt werden.After washing with water, the red mud is dried to 5% moisture. After grinding, the dry material is subjected to a classification process. 1000 kg of the finest fractions obtained are mixed thoroughly with 20 kg of aluminum sulfate powder. A suspension of the powder thus produced has a concentration of 5 g per 100 ml water a pH-value of 7.6. The pigment can be added to the spray liquor, etc. in an amount of about 1 to 5%.
