  Verfahren zur Herstellung einer auch als   Heissdampfzylinderöl   verwendbaren Ölemulsion. 



   Gegenstand der Erfindung bildet ein Verfahren, welches darauf abzielt, Mineralölen mit niedrigem Flammpunkt solche Eigenschaften zu geben, dass sie die Zylinder-o. dgl. Öle mit höherem Flammpunkt (Überhitzeröle) zu ersetzen bzw. zu strecken vermögen. Zu diesem Zwecke ist es erforderlich die Entflammbarkeit, welche z. B. bei den Nassdampfzylinderschmierölen ungefähr zwischen 1400 und 2500 liegt, bei Vermeidung eines Zusatzes solcher Körper, welche die Schmierfähigkeit mindern-oder in den Maschinenteilen'wie Arbeitszylinder von Dampfmaschinen und Wärmemotoren, Dampfturbinen u. dgl. Rückstände hinterlassen, so hoch zu treiben, dass die Mineralöle, trotz ihres niedrigen Flammpunktes bei den Temperaturen des überhitzten Dampfes, das sind Temperaturen von ungefähr 320 bis   3600   C nicht verbrennen oder verkohlen.

   Auch muss hiebei das Zumischen solcher Stoffe vermieden werden, welche die Abnutzung der Laufflächen begünstigen. Ein geeignetes Mittel, den Mineralölen diese erforderlichen Eigenschaften zu'geben, ist die Bildung einer Emulsion durch Zumischen von klarer gesättigter Kalklösung (Kalkwasser). 



   Es wird in bekannter Weise klares, tunlichst gesättigtes Kalkwasser hergestellt und mit Mineralöl z. B. Nassdampfzylinderschmieröl in einer geeigneten Vorrichtung-so innig gemischt oder emulgiert, dass sich die fein verteilten und miteinander vermengteu Mineralölund Kalkwasserteilchen auch bei längerer Lagerung nicht mehr tiennen. 



   Die so gewonnene Emulsion ist sehr haltbar. Das Verbrennen derselben wird durch das Kalkwasser sehr wirksam verhütet und. die Schmierfähigkeit so gut gewahrt, dass der Verbrauch an Emulsion nicht grösser ist als jener bei Verwendung reinen Mineralöls. Da der Kalk o. dgl. nicht in fester oder nur suspendierter Form zugemischt wird, wirkt derselbe weder als die Gleitflächen abnutzendes Poliermittel, noch bleiben von demselben Rückstände in den   Dampfwegen zurück.   



   Durch das Verfahren gemäss der Erfindung werden daher   für Heissdampfzylinder   die Öle verwenbar, die infolge ihres niedrigen Flammpunktes bisher nur für Nassdampf brauchbar waren ;   für Nassdampfzylinderöle, die   bisher ausschliesslich für kalt gehende Maschinenteile bestimmt waren. 



   Selbstverständlich können solche Emulsionen aber auch zum Schmieren kalter Maschinenteile verwendet werden. 
 EMI1.1 
 auch leichtere   Mineralöle   mitzuemulgieren, wodurch eine weitere Streckung des Zylinderöles herbeigeführt wird. 



   Zweckmässig ist die Verwendung einer Emulsion, die ungefähr   50%   gesättigtes Kalkwasser enthält. Eine etwa zu dickflüssige Emulsion kann durch Zusatz dünnflüssiger Öle, welche im Preise niedriger sind als Zylinderöle, verdünnt werden. 



   Die Verwendung von Kalk zur Verseifung fetter Öle ist bekannt. Dagegen besteht die Erfindung in der Verwendung einer gesättigten klaren Kalkwasserlösung für Mineralöle, 

 <Desc/Clms Page number 2> 

 also nicht verseifbare Öle, wobei die Erfindung auf der Feststellung beruht, dass Kalkwasser ein Mittel ist, durch welches die Entflammbarkeit der Mineralöle bei Vermeidung schädlicher Begleiterscheinungen so hoch. getrieben werden kann, als es der jeweilige Verwendungszweck erfordert.

  Process for the production of an oil emulsion which can also be used as a hot steam cylinder oil.



   The subject of the invention is a method which aims to give mineral oils with a low flash point such properties that they the cylinder o. Like. Oils with a higher flash point (superheater oils) to replace or be able to stretch. For this purpose it is necessary the flammability, which z. B. in the wet steam cylinder lubricating oils is approximately between 1400 and 2500, avoiding the addition of such bodies which reduce the lubricity or in the machine parts such as working cylinders of steam engines and heat engines, steam turbines and the like. Like. Leave residues to drive so high that the mineral oils, despite their low flash point at the temperatures of the superheated steam, that is temperatures of about 320 to 3600 C, do not burn or char.

   The addition of substances that promote wear and tear on the running surfaces must also be avoided. A suitable means of adding these required properties to mineral oils is to form an emulsion by adding clear, saturated lime solution (lime water).



   It is made in a known manner clear, saturated lime water if possible and z. B. wet steam cylinder lubricating oil in a suitable device-so intimately mixed or emulsified that the finely distributed and mixed together mineral oil and lime water particles no longer work, even after prolonged storage.



   The emulsion obtained in this way is very durable. The lime water prevents them from burning very effectively and. the lubricity is maintained so well that the consumption of emulsion is not greater than that when using pure mineral oil. Since the lime or the like is not mixed in in solid or only suspended form, it neither acts as a polishing agent that wears off the sliding surfaces, nor does it leave residues in the steam paths.



   The method according to the invention therefore makes it possible to use the oils for superheated steam cylinders which, due to their low flash point, were previously only usable for wet steam; for wet steam cylinder oils that were previously only intended for cold-running machine parts.



   Of course, such emulsions can also be used to lubricate cold machine parts.
 EMI1.1
 also emulsify lighter mineral oils, which leads to a further stretching of the cylinder oil.



   It is advisable to use an emulsion which contains approximately 50% saturated lime water. An emulsion that is too thick can be diluted by adding thin oils, which are lower in price than cylinder oils.



   The use of lime to saponify fatty oils is known. In contrast, the invention consists in the use of a saturated clear lime water solution for mineral oils,

 <Desc / Clms Page number 2>

 that is, non-saponifiable oils, the invention being based on the finding that lime water is a means by which the flammability of the mineral oils is so high while avoiding harmful side effects. can be driven as required by the respective purpose.
