Description
Unoxydierbares Schmiermittel. Die bisher verwendeten neutralen Schmiermittel für Lager, Kolben, Ventile u. dgl. sind bekanntlich, soweit deren Viskosität diejenige des Wassers übertrifft, sämtlich organischer Natur und daher der Oxydation durch freien oder leicht gebundenen Sauerstoff wie durch freie Halogene, insbesondere Chlor, zugänglich.Non-oxidizing lubricant. The neutral lubricants used so far for bearings, pistons, valves and the like are known, insofar as their viscosity is that of water, all of an organic nature and therefore by oxidation free or lightly bound oxygen such as by free halogens, in particular Chlorine, accessible.
In vielen Fällen ist es jedoch wünschenswert, vollkommen unoxydierbare Schmiermittel zu verwenden, so z. B. bei der Schmierung von Lagerteilen, deren Schmiermittel wegen Brand- oder Explosionsgefahr unter keinen Umständen mit stark oxydierenden Stoffen, wie beispielsweise Chloraten, Supercxyden, Nitrokörpern u. dgl., in Berührung kommen darf. Ebenso wichtig ist die Deschaffung eines Schmiermittels, das Kolben undVentile leicht gangbar erhält, mit welchem Gase von hoher Oxydationskraft, insbesondere unter Druck, in Berührung stehen, wie beispielsweise Chlor, verdichteter Sauerstoff USW. In many cases, however, it is desirable to use completely non-oxidizable lubricants, e.g. B. in the lubrication of bearing parts, the lubricant of which, due to the risk of fire or explosion, must under no circumstances come into contact with strongly oxidizing substances such as chlorates, super oxides, nitro bodies and the like. Equally important is the creation of a lubricant that keeps pistons and valves easily accessible, with which gases of high oxidizing power, especially under pressure, are in contact, such as chlorine, compressed oxygen, etc.
Gegenstand der Erfindung sind neutrale Schmiermittel, die aus anorganischen Stoffen bestehen und einer Oxydation durch Sauerstoff oder Halogene nicht fähig sind.The invention relates to neutral lubricants consisting of inorganic Substances exist and cannot be oxidized by oxygen or halogens are.
Wir haben gefunden, daß hochkonzentrierte Lösungen von neutralem Kaliumphosphat (K.HP04) sich vorzüglich als Schmiermittel verwenden lassen, da diese Lösungen, insbesondere im Bereich der spezifischen Gewichte 1,7 bis 1,8q., eine sehr geeigneteViskosität besitzen. Bei einem spezifischen Gewicht von 1,8o weist eine solche Lösung die Eigenschaften eines guten Maschinenöls auf, indem sie bei 2o° C die Viskosität 2o° Engler, bei 50° die Viskosität g_° Engler besitzt. Bei Anwendung des Schmiermittels in nicht in sich abgeschlossenen Räumen ist von Zeit zu Zeit durch Nachprüfung oder durch Durchspülung mit frischer Lösung dafür zu sorgen, daß (infolge Verdampfung) das spezifische Gewicht 1,84 nicht überschritten wird.We have found that highly concentrated solutions of neutral potassium phosphate (K.HP04) can be used excellently as a lubricant, as these solutions, especially in the range of the specific gravity 1.7 to 1.8q., a very suitable viscosity own. With a specific weight of 1.8o, such a solution has the properties of a good machine oil by having a viscosity of 20 ° Engler at 20 ° C 50 ° has the viscosity g_ ° Engler. When using the lubricant in no in self-contained rooms is from time to time by review or by Rinsing with fresh solution to ensure that (as a result of evaporation) the specific gravity of 1.84 is not exceeded.
Es ist weiter gefunden worden, .daß dieses anorganische Schmieröl sehr vorteilhaft auch in die Form eines konsistenten Fettes sich bringen und in den bekannten Staufferbüchsen und ähnlichen Vorrichtungen sich verwenden läßt, wenn es durch Zufuhr von weichen, anorganischen, fein verteilten Stoffen zu geeigneter Verdickung gebracht wird; als solche Stoffe bewähren sich insbesondere Graphit, Talkum und ähnliche Stoffe. Beispielsweise können 300 ccm einerLösung von sekundärem Kaliumphosphat (spezifisches Gewicht 1,785) mit 41o g Talkum (rückstandslos durch 2ooer Sieb gehend) innig zusammengerührt werden, wodurch eine fettähnliche Masse entsteht, die sich insbesondere zur Schmierung von Lagern langsam laufender Maschinenteile eignet.It has further been found that this inorganic lubricating oil can also be very advantageously brought into the form of a consistent grease and used in the known Stauffer boxes and similar devices if it is suitably thickened by the addition of soft, inorganic, finely divided substances will; Graphite, talcum and similar substances in particular have proven themselves as such substances. For example, 300 cc of a solution of secondary potassium phosphate (specific gravity 1.785) with 41o g of talc (passing through a 2oo sieve without leaving any residue) can be intimately mixed, creating a fat-like mass that is particularly suitable for the lubrication of bearings on slow-running machine parts.
Die neuen Schmiermittel in (`51- oder Fettform können für alle üblichen Metalle ihre Anwendung finden, da sie diese dank ihrer vollkommenen Neutralität nicht angreifen.The new lubricants in (`51 or fat form can for all common metals, as they can be used thanks to their perfect Do not attack neutrality.
Die Herstellung der erwähnten Phosphatlösung kann beispielsweise in folgender Weise stattfinden: TechnischePhosphorsäure (48°Be) wird mit festem Ätzkali oder fester Fottasch.e (mindestens 9o prozentig) in kleinen Anteilen vorsichtig neutralisiert, bis ein Tropfen der breiigen Lösung Phenolphthaleinlösung ganz schwach rosa färbt. Dann wird durch hinreichenden Zusatz von Wasser und unter Entfernung etwa vorhandener unlöslicher Anteile die Lösung, gegebenenfalls unter entsprechender Einengung, auf das spezifische Gewicht von etwa i,8o gebracht.The production of the phosphate solution mentioned can, for example, in take place in the following way: Technical phosphoric acid (48 ° Be) is mixed with solid caustic potash or firm Fottasch.e (at least 9o percent) in small portions carefully neutralized until a drop of the pulpy solution phenolphthalein solution is very weak colors pink. Then by adding sufficient water and removing it any existing insoluble fractions the solution, if necessary under appropriate Constriction, brought to the specific gravity of about i, 8o.
