Die vorliegende Erfindung besteht in del Herstellung einer Mischung verschiedener Substanzen, mit welcher man nicht nur Rost (Eisenhydroxyd) sofort vertilgen, sondern bei der Anwendung des Mittels auch verhüten kann, dafs sich die entrosteten MetalloberflächenThe present invention consists in the preparation of a mixture of different substances, with which you not only destroy rust (iron hydroxide) immediately, but also prevent it when using the agent can that the derusted metal surfaces
1S alsbald wieder mit neuem Rost überziehen,' wie dieses bei der Verwendung von Chloriden, organischen und anorganischen Säuren stets der Fall ist. 1 Cover it with new rust as soon as possible, as is always the case with the use of chlorides, organic and inorganic acids.
Genannte Substanzen mufsten bisher nach ihrer Verwendung stets sorgfältig mit reinem WasserSo far, the substances mentioned have always had to be carefully washed with pure water after they have been used
,i von der Metalloberfläche abgewaschen werden; dieses gelang immer nur sehr unvollkommen, da eine gewisse Menge von Feuchtigkeit bezw. verdünnter Saure in den Poren der Metalle festgehalten wprde, wodurch schnelles Wiederrosten stets verursacht wurde. Man hat auch, i wash off the metal surface; this always succeeded only very imperfectly, as a certain amount of moisture respectively. thinner Acid trapped in the pores of the metal, causing rapid re-rusting always caused. One also has
. beobachtet, dafs Objecte aus Eisen und Stahl, welche mit Säuren oder Chloriden entrostet wurden, schon in kurzer Zeit einen stärkeren Rostansatz zeigten wie vorher, und dafs selbst gutes Abreiben und Einfetten dieses nicht verhindern konnte.. observed that objects made of iron and steel, which rust with acids or chlorides showed, within a short time, a stronger rust formation than before, and that itself good rubbing and greasing could not prevent this.
Daher hat man in der Praxis von der Verwendung von Säuren und Chloriden Abstand genommen und lieber den vorhandenen Eisenrost durch Abschleifen mit Schmirgel und anderen Putzmitteln zu beseitigen gesucht, wodurch aber auch der nicht verrostete Theil des Objects in Mitleidenschaft gezogen wurde; andererseits ist es aber auch nicht immer möglich, je nach der Form der zu behandelnden Gegenstände, dem Rost durch Schmirgel etc. beizukommen.For this reason, acids and chlorides are not used in practice and prefer the existing iron rust by sanding with emery and tried to get rid of other cleaning agents, whereby the non-rusted part of the Objects has been affected; on the other hand it is not always possible depending on the shape of the objects to be treated, the rust from emery, etc. to get over.
Durch nachstehende, in ihrer Zusammensetzung näher beschriebene Flüssigkeit wird dem Uebelstande dadurch abgeholfen, dafs man durch Auftragen der Flüssigkeit sofort .jeden Eisenrost beseitigen kann, ohne dafs ein Nachrosten stattfindet. Ein Rostvertilgungsmittel kann aber für die Praxis nur dann einen Werth haben, wenn dieser Bedingung genügt wird. Das hierbei zur Anwendung kommende Mittel besteht aus Rosolsäure, chemisch reiner concentrirter Schwefelsäure, Weinsäure, Ferrosulphat, Kalialaun und einem Pflanzenschleim.The following liquid, which is described in more detail in terms of its composition, becomes the inconvenience was remedied by applying the liquid immediately to each Can remove iron rust without subsequent rusting taking place. A rust killer but can only be of value in practice if this condition is satisfied. The agent used here consists of rosolic acid, a chemically pure concentrate Sulfuric acid, tartaric acid, ferrous sulphate, potash alum and a plant mucilage.
Die Mischung ist in folgender Weise vorzunehmen :The mixture is to be carried out in the following way:
3 g Traganthgummi werden in 100 Theilen Wasser vollständig aufgeweicht, in einer Schale nuf dem Wasserbade verflüssigt und mit einer Lösung von 3,5 g Weinsäure in 50 Theilen Wasser, der unter UmschUtteln 0,5 Theilc chemisch reine Schwefelsäure beigemischt sind, versetzt. In dieses noch warme Säuregemisch wird alsdann die fein pulverisirte Rosolsüure eingetragen und bis zur Lösung der Ruhe überlassen.3 g of gum tragacanth are completely soaked in 100 parts of water in a bowl Liquefied in the water bath and mixed with a solution of 3.5 g of tartaric acid in 50 parts Water to which 0.5 part chemically pure sulfuric acid is mixed with shaking, offset. The finely pulverized rosol acid is then added to this still warm mixture of acids entered and left to rest until the solution.
Das Ganze wird dann so lange gerührt, bis eine homogene Masse entstanden ist.The whole thing is then stirred until a homogeneous mass is formed.
Dieser Mischung wird zuletzt noch eine Lösung von 10 g reinem Ferrosulfat und 5 g Kalialaun in 100 Theilen Wasser zugefügt.This mixture is finally a solution of 10 g of pure ferrous sulfate and 5 g Potash added in 100 parts of water.
Das Ganze wird schliefslich in einer Flasche gut durchgeschüttelt und über Glaswolle abliltrirt. The whole thing is finally shaken well in a bottle and filtered off over glass wool.
Zur Vertilgung von Rost, welcher sich auf gröfseren Objecten vorfindet, werden die oxydirten Stellen mit der Flüssigkeit mehrere Male bestrichen und läfst man dann das Mittel eineIn order to eradicate rust, which is found on larger objects, the oxidized ones are used Smeared areas with the liquid several times and then let the agent
Zeit lang einwirken. Der losgelöste Rost wird darauf mit einem reinen Lappen abgerieben.Act for a long time. The detached rust is then rubbed off with a clean cloth.
Kleinere Objecte, sogen. Massenartikel, welche nicht einzeln behandelt werden können, wie z. B. verrostete Nahnadeln, Fingerhüte, Messerklingen, Stahlfedern, Flaschenverschlüsse, Patronenrahmen aus Stahlblech, Verschraubungen von Geschützen etc., werden in die mit etwas Wasser verdünnte Entrostungsflüssigkeit so lange hineingelegt, bis sich aller Rost losgelöst hat. Die Objecte werden dann aus dem Bade herausgenommen, gut abgeschwenkt und schliefslich mit einer Mischung von 6 Theilen trockenem Sagemehl, 3 Theilen feiner Kreide und 1 Theil pulvcrisirtcm gebrannten Kalk eine Zeit lang umgeschüttelt.Smaller objects, so-called. Bulky items that cannot be handled individually, such as B. rusted sewing needles, thimbles, knife blades, steel springs, bottle caps, cartridge frames made of sheet steel, screw connections of guns, etc., are placed in the rust removal fluid diluted with a little water until all rust has loosened. The objects are then taken out of the bath, swiveled well, and finally shaken for a while with a mixture of 6 parts dry sawdust, 3 parts fine chalk, and 1 part powdered lime.
Eisen und Stahl, selbst deren Politur, werden' von der EntrostungsHUssigkeit nicht angegriffen. Iron and steel, even their polish, are not attacked by the rust removal.
