Description

Verfahren zum Lösen festgerosteter oder festgebrannter Apparateteile In der Technik macht es oft Schwierigkeiten, festgerostete oder festgebrannte Al)-parateteile, z. B. Schrauben, Verzahnungen u. dgl., wieder zu lösen. Man hat bisher zu diesem Zwecke Petroleumkohlenwasserstoffe oder ähnliche Produkte verwendet, deren Anwendung aber oft nicht den gewünschten Erfolg hatte.Process for loosening rusted or burnt-on apparatus parts In technology, it is often difficult to find rusted or burnt-in aluminum parts, z. B. screws, teeth and the like. To solve again. One has so far to this Purposes used petroleum hydrocarbons or similar products, their application but often did not have the desired success.

Es wurde nun gefunden, daß man mit ganz , au -;,<1---zeiclinetein Erfolg auch in besonders hartnäckigen Fällen sehr rasch die festgerosteten oder festgebranntenApparateteilelösen oder wieder gangbar machen kann. wenn man diese mit Hvdrierungsprodukten von Phenolen oder mit hydroaromatischen Ketonen, z. B. Metl)vlcvclohexanon, oder deren Mischungen benetzt. Die genannten Flüssigkeiten dringen außerordentlich schnell und tief zwischen die festgerosteten oder festgebrannten Apparateteile ein, und nach kurzer Zeit ist es möglich, die Teile - ohne sie zu zerstören - ::u bewegen oder loszulösen.It has now been found that with very , au -; if this is done with hydrogenation products of phenols or with hydroaromatic ketones, e.g. B. Metl) vlcvclohexanon, or mixtures thereof wetted. The liquids mentioned penetrate extremely quickly and deeply between the rusted or burnt-on parts of the apparatus, and after a short time it is possible to move or detach the parts - without destroying them.

Als geeignete Mischungen zum Lösen festgerosteter Apparateteile kommen alle Mischungsverhältnisse der Hydrierungsl)rodlil:te von Phenolen und livdroaromatischen betonen von z. 13. r bis 99 °/" Cyclohexanon oder Methylcyclohexanon mit c)9 bis r "/" Cyclohexanol oder Methylcyclohexanol in Betracht. Ferner lassen sich alle Mischungen dieser Produkte mit Phenolen, z. B. 6o Methylcyclohexanon. 35 °/" Methylanol und ; "/" Kresol, mit Vorteil verwenden sowie auch Mischungen mit Petroleumkohlenwasserstoffen, wasserfreien (der wasserhaltigen Alkoholen, z. B. eine Mischung aus 40 °/o Methvlcvclohexanon, 20 "/" MetliVlcyclohexanol, 40 "/" Petroleum oder 30 "/" Cyclohexanon, 5o "/" Cvcloltexanol, 2o "/" 5l)iritUs. Die als Beispiele angeführten Gcinische lassen sich in ihrer Zusainmet)setzung in weiten Grenzen ändern, ohne daß die Eigenschaft, festgerostete oder festgebrannte Apparateteile zu lösen, beeinträchtigt würde.Suitable mixtures for dissolving rusted-on parts of the apparatus are all mixing ratios of the hydrogenation / rodlil: te of phenols and livdroaromatic emphasize z. 13. r to 99 ° / "cyclohexanone or methylcyclohexanone with c) 9 to r" / "cyclohexanol or methylcyclohexanol. Furthermore, all mixtures of these products with phenols, for example 6o methylcyclohexanone. 35 ° /" methylanol and; Use "/" cresol with advantage, as well as mixtures with petroleum hydrocarbons, anhydrous (the water-containing alcohols, e.g. a mixture of 40% methylclohexanone, 20 "/" metalcyclohexanol, 40 "/" petroleum or 30 "/" cyclohexanone , 5o "/" Cvcloltexanol, 2o "/" 5l) iritUs. The composition of the niches given as examples can be varied within wide limits without impairing the property of loosening rusted or burnt-on parts of the apparatus.
