Description

Verfahren zur Farbverbesserung von grüner Erde Unter grüner Erde im engeren Sinne versteht man zwei Mineralien, Glaukonit und Seladonit, in weiterem Sinne alle möglichen Gesteinstrümmer oder zu Erde zerfallene Naturprodukte, die zum großen Teil grau sind und die noch einen grünen Schimmer erkennen lassen. Beide Grüppen können zusammengefaßt werden als Ferrosilikate, gegebenenfalls noch in Anwesenheit von Fernsilikaten, die außer dem Aluminium-, Eisenverbindungen und Kalk enthalten. Hierbei ist es unerheblich, in welchen Mengen neben den Silikaten die Metalloxyde vorkommen.Process for color improvement of green earth Unter green earth im In a narrower sense, one understands two minerals, glauconite and celadonite, in a broader sense Meaning all sorts of debris or natural products that have crumbled to earth are mostly gray and still have a green sheen. Both Groups can be summarized as ferrosilicates, if necessary still in the presence of remote silicates, which contain besides aluminum, iron compounds and lime. It is irrelevant in what quantities, in addition to the silicates, the metal oxides occurrence.

Es wurde nun gefunden, daß die Farbverbessrung von grüner Erde durch Behandlung mit Reduktionsmitteln zu erzielen ist. Als Reduktionsmittel sind die Hydrosulfite (z. B. Natriumhydrosulfit, Kaliumhydrosulfit, basische Zinkhydrosulfit-Aldehyd-Verbindungen) geeignet. Hierbei kann man nach den Methoden der Küpenfärberei arbeiten. Ein Vorteil dieser Farbverbesserung ist die Herstellung von deckenden und nicht basierenden Farben. Es wird eine Umwandlung von apfelgrüner Erde in einen olivgrünen Farbton erzielt, ebenso werden die grauen und graugrünen vorkommenden Erden in tiefgrüne Farbstoffe umgewandelt.It has now been found that the color improvement of green earth by Treatment with reducing agents is to be achieved. As reducing agents are the Hydrosulfites (e.g. sodium hydrosulfite, potassium hydrosulfite, basic zinc hydrosulfite-aldehyde compounds) suitable. Here you can work according to the methods of vat dyeing. An advantage This color enhancement is the manufacture of opaque and non-based Colours. There will be a transformation from apple green earth to an olive green hue also the gray and gray-green occurring earths are transformed into deep green ones Converted dyes.

Beispiele _. In eine warme, verdünnte alkalische Lösung von 3 kg Hydrosulfit in zoo 1 Wasser werden =oo kg grüne Erde zweckmäßig nach dem Einteigen eingetragen. Man verrührt die Mischung gegebenenfalls unter weiterem Zusatz von heißem Wasser. Die Reaktion, die durch den Farbumschlag erkennbar ist, beginnt augenblicklich. Es wird bis zur Erreichung des gewünschten Farbtones gerührt, wozu mehrere Stunden erforderlich sind, und darauf filtriert. Nach der Filtration wird die grüne Erde mit Wasser gewaschen und getrocknet.Examples _. In a warm, dilute alkaline solution of 3 kg of hydrosulfite In zoo 1 water, = oo kg of green earth is expediently entered after it has been poured in. The mixture is stirred, optionally with further addition of hot water. The reaction, which can be recognized by the color change, begins immediately. It is stirred until the desired color is achieved, which takes several hours are required and then filtered. After filtration, the earth becomes green washed with water and dried.

2. Unter Einhaltung der gleichen Gewichtsverhältnisse wie in Beispiel z wird das zweckmäßig mit Wasser angeteigte Pulver der grünen Erde in heißes alkalihaltiges Wasser eingetragen und unter Rühren Hydrosulfit in der angegebenen Menge in kleinen Portionen hinzugefügt.2. While maintaining the same weight ratios as in the example z the green earth powder, which is expediently made into a paste with water, is converted into hot, alkaline powder Entered water and with stirring hydrosulfite in the specified amount in small Portions added.

Die Behandlung mit den Reduktionsmitteln grüner Erde erfolgt bei Temperaturen von 50 bis 95'C. Die erforderlichen Mengen an Reduktionsstoffen sind j e nach der Farbe des Ausgangsmaterials sowie für den erzielten Farbton des Endproduktes verschieden.The treatment with the reducing agents of green earth takes place at temperatures from 50 to 95'C. The required amounts of reducing substances depend on the Color of the raw material as well as for the achieved shade of the end product different.
