Description

Verfahren zum Desoxydieren oxydierter Metallflächen sowie zum Schützen von Metallflächen gegen Oxydation mittels Schutzanstrichs Die Erfindung gründet sich auf die Beobachtung, daß im Seeschlick und in bestimmten Süßwasserschlammstoffen; welche vorwiegend aus anorganischen Substanzen und verhältnismäßig nur geringen organischem Stoffresten bestehen, sich ungesättigte, d. h. sauerstoffarme Siliciumverbindungen befinden, und daß diese die Fähigkeit besitzen, oxydierte Metallflächen zu desoxydier en, sich mit den Metallen an der Oberfläche chemisch zu verbinden und sie gegen eine Oxydation zu schützen.Process for deoxidizing and protecting oxidized metal surfaces of metal surfaces against oxidation by means of protective paint The invention is founded on the observation that in the sea mud and in certain freshwater muds; which mainly consist of inorganic substances and only minor ones consist of organic material residues, unsaturated, d. H. low-oxygen silicon compounds are located, and that these have the ability to deoxidize oxidized metal surfaces en to chemically combine with the metals on the surface and against them to protect against oxidation.

Diese siliciumreichen Naturschlämme unterscheiden sich von den Faulschlämmen (SapropelSaprokoll) durch ihren hohen Gehalt an Siliciumverbmdungen und Metallverbindungen und nur geringen orgadschen Substanzen. Faulschlämme bestehen vorwiegend aus organischer Substanz mit nur sehr geringen Mengen anorganischer Stoffe. Sie sind deshalb arm an Siliciumverbinduggen.These silicon-rich natural sludges differ from digested sludge (SapropelSaprokoll) due to their high content of silicon compounds and metal compounds and only minor organic substances. Digested sludge consists mainly of organic Substance with only very small amounts of inorganic substances. That's why they're poor of silicon compounds.

In vorliegendem. Falle handelt es sich um die Verwendung silüciumreicher Naturschlamrnstoffe, die geeignet sind, die Metalloxyde oberflächlich umzuwandeln, die Me-' talle zu verkieseln und praktisch sich mit den Metallen oberflächlich zu verbinden, weshalb eine innige Berührung dieser aktivem Kolloidstoffe mit den Metallen unter Mitverwendungeines geeigneten Bindemittels bzw. Filmbildestoffes notwendig ist.In the present. Trap is the use of silicon-rich Natural sludge that is suitable for converting the metal oxides on the surface, the metals to silicify and practically become superficially with the metals connect, which is why these active colloidal substances come into close contact with the metals necessary with the use of a suitable binder or film-forming substance is.

Das Verfahren besteht in folgendem: Der wie oben gekennzeichnete Naturschlamm wird entweder im rohen Zustande im Vakuum getrocknet, gepulvert und windgesichtet oder besser noch, die in denn rohen Schlick enthaltenen wirksamsten feinststofilichen Substanzen werden durch Aufschlämmen und Abscheiden von den gröberen kristaEinischen, inaktiven Körperstoffen getrennt.- Alsdann werden die gewonnenen Stoffe im Vakuum 'bei relativ niederen Temperaturen getrocknet, um den Wasserentzug zu bewirken.The procedure consists of the following: The natural sludge marked as above is either dried in the raw state in a vacuum, powdered and wind-sifted or better still, the most effective finest filiches contained in the raw silt Substances are removed by slurrying and separating from the coarser crystalline niches, Inactive body substances separated.- Then the extracted substances are in a vacuum 'Dried at relatively low temperatures to effect dehydration.

Die getrockneten, gemählenen und etwa windgesichteten Schlickkörper werden alsbald mit einem filmbildenden Öl, Lack o. dgl. mit oder ohne Zusatz von Farben oder sonstigen als Zusatz zu Anstrich- und Rostschutzniitteln geeigneten Stoffen in biekannter Welse innigst vermischt.The dried, ground and roughly wind-sifted bodies of silt are soon treated with a film-forming oil, varnish or the like. With or without the addition of Paints or other suitable additives to paints and anti-rust agents Fabrics in well-known catfish are intimately mixed.
