Description

Verfahren zum Reinigen von Gegenständen Es ist bekannt, Gegenstände, vornehmlich solche aus Metall, die mit Staub, Polier- oder Schleifpaste behaftet sind, mittels organischer Lösungsmittel, z. B. Chlorkohlenwasserstoffen, wie Trichloräthylen, Perchloräthylen u. dgl., zu reinigen. Auf diese Weise werden aber nur Öle, Fette, Wachse u. dgl. entfernt, während Staub, Schmirgel usw. haften, bleiben.Methods for cleaning objects It is known to use objects, mainly those made of metal that are covered with dust, polishing or grinding paste are, by means of organic solvents, e.g. B. chlorinated hydrocarbons, such as trichlorethylene, Perchlorethylene and the like. In this way only oils, fats, Waxes and the like removed, while dust, emery, etc. adhere, remain.

Eine Möglichkeit zur Entfernung solcher festhaftender Substanzen besteht darin, daß Emulsionen verwendet werden, die noch mindestens einen feinverteilten, in der Emulsion unlöslichen festen Stoff enthalten, wie Holzmehl, Lederstückchen. Zur Erhöhung der Stabilität solcher Emulsionen werden wasserlösliche Cellulosederivate, wie celluloseglykolsaures Natrium, gelegentlich zugegeben.There is a possibility of removing such firmly adhering substances that emulsions are used that contain at least one finely divided, Contain insoluble solid matter in the emulsion, such as wood flour, bits of leather. To increase the stability of such emulsions, water-soluble cellulose derivatives, such as sodium cellulose glycolate, added occasionally.

Es ist fernhin bekannt, daß ein umfangreicher Komplex von Eigenschaften Einfluß auf das Reinigungsvermögen hat, wie z. B. die Viskosität usw.It is widely known to have an extensive complex of properties Has influence on the cleaning ability, such. B. the viscosity etc.

Es wurde gefunden, daß bei der Reinigung von Gegenständen, vornehmlich Metallen, die mit Staub, Schleifmitteln, Fetten oder Ölen behaftet sind, mittels organischer Lösungsmittel, z. B. Chlorkohlenwasserstoffe, wie Trichloräthylen oder Perchloräthylen, günstige Ergebnisse erzielt werden, wenn die Gegenstände in wasserfreie organische Lösungsmittel getaucht werden, deren Viskosität durch Zusatz von Celluloseacetatpulver auf mindestens 1,5 cP erhöht wird.It has been found that when cleaning objects, especially Metals that are covered with dust, abrasives, greases or oils, by means of organic solvent, e.g. B. chlorinated hydrocarbons, such as trichlorethylene or Perchlorethylene, favorable results are obtained when the objects are in anhydrous Organic solvents are immersed, their viscosity due to the addition of cellulose acetate powder is increased to at least 1.5 cP.

Mit diesem Verfahren gelingt es, bei einer Viskosität von 2,4 cP z. B. einen Reinigungseffekt in einigen Sekunden zu erzielen, während bei anderen Zusätzen die zehnfache Zeit oder noch längere Zeiten benötigt werden. Außerdem ist dadurch ein fleckenfreies Reinigen möglich, da wasserfreie organische Lösungsmittel zur Anwendung kommen.With this method it is possible, at a viscosity of 2.4 cP z. B. to achieve a cleaning effect in a few seconds, while other additives ten times the time or even longer times are required. Besides, through it Spot-free cleaning is possible, as anhydrous organic solvents are used Application.

Das Reinigen kann in der Kälte oder unter Erwärmung, aber auch im kochenden Zustande des Lösungsmittels erfolgen. Man bedient sich dabei zweckmäßig der üblichen Metallreiniger, die unten beheizbar und oben gekühlt und mit einer Absaugung versehen sind.Cleaning can be done in the cold or under warming, but also in boiling conditions of the solvent take place. One makes use of it appropriately the usual metal cleaners, which can be heated at the bottom and cooled at the top and with a Suction are provided.
