Description
Die Erfindung bezieht sich auf ein entfernbares Korrosionsschutzmittel für Metallteile nach dem Oberbegriff des Anspruchs 1.The invention relates to a removable corrosion inhibitor for metal parts according to the preamble of claim 1.
Bei der Herstellung und der Verarbeitung von Metallteilen, insbesondere bei spangebenden Formprozessen, ist es üblich, die Metallteile vorübergehend mit einer wachs- oder fettartigen Substanz zu beschichten, um Korrosionsprozesse zu verhindern. Später werden derartige Beschichtungen zumeist entfernt, damit eine dauerhafte Korrosionsschutzschicht aufgetragen werden kann.When manufacturing and processing metal parts, especially in machining processes, it is common practice to temporarily coat the metal parts with a waxy or fatty substance to prevent corrosion processes. Such coatings are usually removed later so that a permanent corrosion protection layer can be applied.

Es ist bekannt, daß Nickel Allergie auslöst. Es genügen bereits Spuren von Nickel, um eine allergene Reaktion hervorzurufen. Viele Metallwerkstücke, insbesondere aus Eisen, enthalten mehr oder weniger große Nickelanteile. Sie können daher bei Personen, die mit derartigen Metallwerkstücken in Berührung kommen, eine Energie auslösen, wenn eine entsprechende Empfindlichkeit vorhanden ist.It is known that nickel causes allergies. Even traces of nickel are enough to cause an allergic reaction. Many metal workpieces, especially those made of iron, contain more or less large amounts of nickel. They can therefore trigger an energy reaction in people who come into contact with such metal workpieces if they are sensitive to it.
Der Erfindung liegt die Aufgabe zugrunde, ein Mittel anzugeben, mit dem die Auslösung von Nickelallergien gehemmt wird.The invention is based on the object of specifying a means by which the triggering of nickel allergies is inhibited.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1.This object is achieved according to the invention by the features of claim 1.
Es hat sich überraschend gezeigt, daß die Anwesenheit von Kupferionen das Entstehen allergischer Reaktionen auf Nickel unterbindet, zumindest jedoch stark abschwächt. Welche chemischen Prozesse und physiologischen Reaktionen hierfür ursächlich sind, ist zur Zeit noch nicht geklärt.Surprisingly, it has been shown that the presence of copper ions prevents the occurrence of allergic reactions to nickel, or at least significantly reduces them. The chemical processes and physiological reactions that cause this are not yet clear.
Der Anteil von Kupferionen abgegebenen Substanzen im Korrosionsschutzmittel kann relativ gering sein, unter Umständen reicht eine spurenweise Beimischung aus. Beson-The proportion of substances released by copper ions in the corrosion inhibitor can be relatively low; in some cases, a trace amount is sufficient.
ders vorteilhaft ist die Verwendung von sehr feinem Kupfer oder feiner Kupferlegierung, z.B. in Pulverform, das in gleichmäßiger Verteilung dem Korrosionsschutzmittel beigemischt ist.It is particularly advantageous to use very fine copper or fine copper alloy, e.g. in powder form, which is mixed into the corrosion inhibitor in an even distribution.
Als Korrosionsschutzmittel für Metallteile kommen herkömmliche geeignete Substanzen in Betracht, wie zum Beispiel Paraffin oder sonstige Mineralfette.Conventional suitable substances, such as paraffin or other mineral greases, can be considered as corrosion inhibitors for metal parts.
Paraffin als Korrosionsschutzmittel und pulverisiertes Kupfer in einem Anteil von 0,4 Gew.-% wird dem Paraffin mit einem bekannten Verfahren zugemischt.Paraffin as a corrosion inhibitor and powdered copper in a proportion of 0.4 wt.% are mixed into the paraffin using a known process.
