Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Reinigen von Gegenständen der im übrigen im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a method for cleaning of objects otherwise in the preamble of claim 1 Art.
Es ist bekannt, Gegenstände aus Metall, Glas, Keramik, Kunst stoff od. dgl. zu reinigen, um bei diesen insbesondere an den Oberflächen Schmutz, Fette, Öle, Wachse, Harze od. dgl. zu entfernen. Dies geschieht in geschlossenen Behältern von entsprechenden Reinigungsanlagen. Man verwendet dazu in bekannter Weise flüssige Reinigungsmittel, die Lösungs mittel enthalten, vor allem Kohlenwasserstofflösungsmittel, die sich für diesen Zweck als Entfettungsflüssigkeit gut eignen. Dies gilt vor allem für die Kohlenwasserstofflösungsmittel Trichloräthylen und Perchloräthylen, die zur Gruppe der Halogen kohlenwasserstoffe gehören. Derartige Reinigungsmittel, die Kohlenwasserstofflösungsmittel enthalten, sind vor allem aus umweltpolitischen Gesichtspunkten in hohem Maße unerwünscht. Dies zum einen aus gesundheitlichen Gründen, auch aus Gründen der Arbeitshygiene, und zum anderen insbesondere wegen Entsorgungs problemen und der unzulänglichen biologischen Abbaubarkeit. Vor allem dann, wenn ein solches flüssiges Reinigungsmittel auf hohe Temperaturen gebracht werden muß, um eine Reinigung, insbesondere Entfettung, zu erreichen, die je nach Ver schmutzungsgrad und Oberflächenzustand erst bei höheren Temperaturen erreicht werden kann, wird der Siedepunkt eines solchen Lösungsmittels erreicht. Es entstehen ätzende Dämpfe, die die Umwelt und das Personal stark belasten und in aufwendiger Weise zurückgewonnen werden müssen, um die Umweltbelastung möglichst gering zu halten.It is known objects made of metal, glass, ceramics, art to clean fabric or the like, in order to in particular to the Surfaces dirt, greases, oils, waxes, To remove resins or the like. This happens in closed Containers from corresponding cleaning systems. One uses in addition, in a known manner, liquid detergents, the solutions contain agents, especially hydrocarbon solvents, which are well suited for this purpose as a degreasing liquid. This is especially true for the hydrocarbon solvents Trichlorethylene and perchlorethylene, which belong to the group of halogen include hydrocarbons. Such cleaning agents that Hydrocarbon solvents are mostly made up of highly undesirable from an environmental perspective. On the one hand for health reasons, also for reasons occupational hygiene, and especially because of waste disposal problems and inadequate biodegradability. In front especially when such a liquid detergent high temperatures must be brought to a cleaning, especially degreasing, which depending on Ver Degree of soiling and surface condition only at higher Temperatures can be reached, the boiling point of such a solvent. Arise corrosive vapors, the environment and the staff strong burden and be recovered in a complex manner in order to keep the environmental impact as low as possible.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der im Oberbegriff des Anspruchs 1 genannten Art zu finden, das bei hohen Temperaturen eine umweltschonende Reinigung mit hoher Reinigungswirkung ermöglicht.The invention has for its object a method of the type mentioned in the preamble of claim 1, an environmentally friendly one at high temperatures Allows cleaning with a high cleaning effect.
Diese Aufgabe ist bei einem Verfahren der eingangs ge nannten Art gemäß Erfindung durch die Merkmale im Kenn zeichnungsteil des Anspruchs 1 gelöst. Vorteilhafte Weiter bildungen dieses erfindungsgemäßen Verfahrens ergeben sich aus den Ansprüchen 2-4. Die Erfindung macht es möglich, den grundsätzlich aus den Faktoren Chemie, Zeit, Mechanik und Temperatur bestehenden Reinigungsvorgang möglichst umweltschonend zu gestalten und gleichwohl eine große Reinigungswirkung zu erzielen. Dabei ist auch eine Hoch temperaturreinigung mit gleichen Vorteilen möglich, so daß eine einwandfreie Reinigung, z. B. Entfettung, auch bei diesbezüglich kritischen Teilen möglich ist, insbe sondere bei polierten Teilen oder solchen, denen Zieh fette anhaften, bei denen eine Schmutzentfernung erst bei hohen Temperaturen erreichbar ist. Durch die den Siede punkt des Wassers erhöhenden Zusätze zum wäßrigen Wasch mittel ist eine Hochtemperaturreinigung ohne Erreichen des Verdampfungspunktes des wäßrigen Waschmittels mit Zusatz möglich. Ferner wirken sich diese den Siedepunkt des Wassers erhöhenden Zusätze, z. B. Äthylenglykol, zu sätzlich noch günstig, nämlich steigernd, auf die Wasch wirkung aus. Das erfindungsgemäße Verfahren ermöglicht insgesamt somit eine bei hohen Temperaturen umwelt schonende Reinigung mit hoher Reinigungswirkung.This task is ge in a process of the beginning named type according to the invention by the features in the characteristic Drawing part of claim 1 solved. Advantageous next formations of this method according to the invention result from claims 2-4. The invention makes it possible basically from the factors chemistry, time, mechanics and temperature existing cleaning process if possible environmentally friendly and still a big one To achieve cleaning effect. There is also a high temperature cleaning possible with the same advantages, see above that proper cleaning, e.g. B. degreasing, too critical parts are possible, especially especially with polished parts or those that pull adhere greases, where a dirt removal only at high temperatures can be reached. By the boilers point of water-increasing additives to the aqueous wash medium is a high temperature cleaning without reaching the evaporation point of the aqueous detergent Addition possible. They also affect the boiling point of water-increasing additives, e.g. B. ethylene glycol additionally cheap, namely increasing, on the wash effect. The method according to the invention enables overall thus an environment at high temperatures gentle cleaning with high cleaning effect.
Ein erfindungsgemäßes Reinigungsmittel, das bei diesem Verfahren zum Einsatz kommen kann, ist durch die Merkmale im Anspruch 5 gekennzeichnet. Vorteilhafte Weiterbildungen dazu ergeben sich aus den Ansprüchen 6 und 7. Dieses er findungsgemäße Reinigungsmittel ist in hohem Maße umwelt freundlich. Das Reinigungsmittel besitzt eine hervor ragende Reinigungswirkung und stellt anders als solche, die Kohlenwasserstofflösungsmittel enthalten, keine Gefahr für die Umwelt und das Personal dar. Es ist auch nicht zwingend, obwohl natürlich vorteilhaft, dieses Reinigungs mittel zurückzugewinnen. Das Reinigungsmittel läßt sich durch entsprechende Zusätze zum Wasser so einstellen, daß es vollständig biologisch abbaubar ist. Es versteht sich, daß als Zusätze zum Wasser vielfältige Stoffe in Frage kommen, die nicht umweltbelastend sind und üblicherweise im Zusammenhang mit Reinigungsproblemen mit verwendet werden. Das erfindungsgemäße Reinigungsmittelführt insge samt zu einer Erhöhung der Reinigungskraft sowie einer Reduzierung der Risiken bezüglich einer Umweltverschmutzung und Risiken bezüglich der Arbeitshygiene, vor allem in Kombination mit Wasser. Das erfindungsgemäße Reinigungs mittel kann mit besonderem Vorzug bei der Entfettung oder überhaupt bei der Reinigung von Teilen aus Metall und/oder Glas und/oder Keramik und/oder Kunststoff od. dgl. zur Anwendung kommen.An inventive cleaning agent that this Process can be used is due to the characteristics characterized in claim 5. Advantageous further training in addition arise from claims 6 and 7. This he detergent according to the invention is highly environmental friendly. The detergent has one excellent cleaning effect and, unlike them, containing hydrocarbon solvents, no danger for the environment and the staff. It is also not mandatory, although of course advantageous, this cleaning to recover funds. The detergent can be with appropriate additives to the water so that it is completely biodegradable. It goes without saying that as additives to water various substances in question come that are not polluting and usually used in connection with cleaning problems will. The cleaning agent according to the invention leads in total together with an increase in cleaning power as well as a Reduction of risks related to pollution and risks related to occupational hygiene, especially in Combination with water. The cleaning according to the invention medium can with particular preference for degreasing or at all when cleaning metal parts and / or glass and / or ceramic and / or plastic or the like. come into use.
