Die Erfindung betrifft ein Mittel zur Reinigung von Abflußrohren.The invention relates to an agent for cleaning drain pipes.
Zur Reinigung verstopfter Abflußrohre im privaten und gewerblichen Bereich sind neben mechanischen Mitteln sog. Abflußreiniger bekannt. Die Ursache für die Verstopfung von Abflußrohren ist in der Regel ein Pfropfen, der aus Fett, Haaren , Küchenabfällen u. dgl. besteht. Durch Entfernen des Fettes können derartige Pfropfen meist aufgelöst werden. Das Fett kann durch Verseifung mit Laugen und/oder durch Emulgieren mit Detergentien gelöst werden, was jedoch mit Nach-In addition to mechanical means, so-called drain cleaners are known for cleaning blocked drain pipes in private and commercial areas. The cause of blockages in drain pipes is usually a plug made of grease, hair, kitchen waste, etc. Such plugs can usually be dissolved by removing the grease. The grease can be dissolved by saponification with alkalis and/or by emulsification with detergents, but this is not always easy.
teilen verbunden ist, da einerseits die Materialien der Abflüssen angegriffen werden und andererseits die Belastung der Abwasser sehr hoch ist.parts, because on the one hand the materials of the drains are attacked and on the other hand the pollution of the waste water is very high.
Aus der EP 0 236 989 B1 ist ein Verfahren zur Reinigung von Abflußrohren bekannt, bei dem den in Abwässern vorkommenden fettabauenden Mikroorganismen Suppline, d. h. Stoffe, die zum Grundbestand einer Zelle gehören und die von den Organismen nicht selbst synthetisiert werden können, zuführt werden, wodurch der Fettabbau und damit auch die Auflösung eines Pfropfens bewirkt wird. Nachteilig bei diesem Verfahren ist es jedoch, daß die Größe der natürlicherweise vorliegenden Mikroorganismenpopulation sehr stark variieren kann, so daß ggf. eine sehr lange Einwirkdauer einkalkukiert werden muß, da ein wirksamer Abbau des Fettes erst einsetzt, wenn genügend Mikroorganismen vorhanden sind.EP 0 236 989 B1 describes a process for cleaning drain pipes, in which the fat-degrading microorganisms found in waste water are fed supplins, i.e. substances that are part of the basic structure of a cell and that cannot be synthesized by the organisms themselves, which causes the fat to be broken down and thus the plug to dissolve. The disadvantage of this process, however, is that the size of the naturally occurring microorganism population can vary greatly, so that a very long exposure time may have to be taken into account, since effective fat degradation only begins when sufficient microorganisms are present.
Es ist daher Aufgabe der Erfindung, ein Mittel zur Reinigung von Abflußrohren zu schaffen, das gegenüber den Materialien des Abflußsystems nicht korrosiv oder in anderer Weise zerstörend wirkt, das die Abwässer nicht belastet und zudem unabhängig von der Populationsgröße der entsprechenden Mikroorganismen im Abwasser bzw. in den Abflußrohren wirkt.It is therefore an object of the invention to provide a means for cleaning drain pipes which is not corrosive or otherwise destructive to the materials of the drainage system, which does not pollute the waste water and which also works independently of the population size of the corresponding microorganisms in the waste water or in the drain pipes.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.
Dazu ist erfindungsgemäß vorgesehen, ein Mittel zur Reinigung von Abflußrohren zu schaffen, das Lipase enthält. Ein derartiges Mittel baut Fettablagerungen in Abflußrohren auf enzymatische Weise ab, so daß die der Erfindung zugrunde liegende Aufgabe voll erfüllt wird.For this purpose, the invention provides for a means for cleaning drain pipes that contains lipase. Such a means breaks down fat deposits in drain pipes in an enzymatic manner, so that the object underlying the invention is fully fulfilled.
Vorzugsweise enthält das erfindungsgemäße Mittel zur Reinigung von Abflußrohren, das in dieser Ausführungsform in fester Form, d. h. als rieselfähiges Granulat oder Pulver vorliegt, neben der Lipase zusätzlich noch Mikroorganismen zum Abbau von Fetten, so daß vorteilhafterweise unabhängig von Art und Anzahl der Mikroorganis-Preferably, the agent according to the invention for cleaning drain pipes, which in this embodiment is in solid form, i.e. as free-flowing granules or powder, contains, in addition to the lipase, microorganisms for breaking down fats, so that advantageously, regardless of the type and number of microorganisms,
men in dem Abwasser die Reinigung des Abflußrohres erfolgen kann. Bevorzugterweise sind die Mikroorganismen des Mittels auf einem Träger befindlich, der durch Getreideschrot gebildet werden kann, das zusätzlich noch mit Mineralsalzen und Salzen von Spurenelementen versehen sein kann.in which the waste water can be used to clean the drain pipe. Preferably, the microorganisms of the agent are located on a carrier, which can be formed by grain meal, which can also be provided with mineral salts and salts of trace elements.
Weiterhin können andere übliche Inhaltsstoffe, wie z. B. Natriumbicarbonat, Citronensäure, Natriumnitrat und ggf. Parfümöl in dem Mittel enthalten sein. Es können auch Tenside enthalten sein, jedoch zeigt sich, daß gegenüber den bekannten Rohrreinigungsprodukten aus dem Stand der Technik, die nur das Wachstum von im Abflußrohr vorhandenen Mikroorganismen fördern und zusätzlich Tenside enthalten, bei dem erfindungsgemäßen Mittel auf Tenside verzichtet werden kann, da auch ohne Tenside die Reinigungskraft größer ist als bei den bekannten Reinigungsmitteln, wodurch die Belastung der Gewässer verringert werden kann.Furthermore, other common ingredients such as sodium bicarbonate, citric acid, sodium nitrate and possibly perfume oil can be included in the product. Surfactants can also be included, but it has been shown that, in contrast to the known pipe cleaning products from the state of the art, which only promote the growth of microorganisms present in the drain pipe and also contain surfactants, surfactants can be dispensed with in the product according to the invention, since even without surfactants the cleaning power is greater than with the known cleaning products, which can reduce the pollution of the water.
Nach einer anderen Ausführungsform liegt das erfindungsgemäße Mittel zur Reinigung von Abflußrohren in flüssiger Form vor. Bei dieser Ausführungsform des Mittels ist vorzugsweise neben Lipase ein Alkohol, vorzugsweise Ethanol, und/oder ein Tensid, vorzugsweise Natriumlaurylsulfat, sowie Wasser enthalten. Weiterhin können andere übliche Inhaltsstoffe zugegen sein.According to another embodiment, the agent according to the invention for cleaning drain pipes is in liquid form. In this embodiment of the agent, in addition to lipase, an alcohol, preferably ethanol, and/or a surfactant, preferably sodium lauryl sulfate, as well as water are preferably contained. Furthermore, other usual ingredients can be present.
Das Mittel in flüssiger Form weist die gleiche Wirksamkeit wie übliche Rohrreiniger auf, jedoch ohne eine derartig hohe Abwasserbelastung zu bewirken.The liquid product is just as effective as conventional pipe cleaners, but without causing such a high level of wastewater pollution.
Das erfindungsgemäße Mittel zur Reinigung von Abflußrohren ermöglicht vorteilhafterweise nicht nur die Reinigung bei einer akuten Verstopfung eines Abflußrohres sondern auch eine vorbeugende Anwendung, da bei regelmäßiger Anwendung, insbesondere der festen Ausführungsform, eine allmähliche Zusetzung des Abflußrohres verhindert wird.The agent according to the invention for cleaning drain pipes advantageously enables not only cleaning in the event of an acute blockage of a drain pipe but also preventive use, since regular use, in particular of the solid embodiment, prevents gradual clogging of the drain pipe.

Karottensalat 17,2 Gew.%,Carrot salad 17.2% by weight,
Teeblätter, gekocht und getrocknet 6,7 Gew.%.Tea leaves, cooked and dried 6.7% by weight.
Zur Herstellung der Masse werden Schmalz und Kokosfett geschmolzen. Anschließend werden die Haare zugegeben und die Masse durchmischt. Danach werden die restlichen Bestandteile zugegeben und die Masse erneut durchmischt. Von der fertig gemischten Masse werden 17,0 g handwarm in eine Form gedrückt, die aus einer Plexiglasröhre mit einem Durchmesser von 3,4 cm besteht. Die Masse wird in der Röhre mittels zwei Stempeln auf eine Höhe von 1,8 cm gepreßt. Nach dem Herauspressen der Masse wird diese im Kühlschrank für mindestens 24 Stunden gelagert und 30 min. vor Versuchsbeginn aus dem Kühlschrank herausgenommen.To make the mass, lard and coconut oil are melted. Then the hair is added and the mass is mixed. Then the remaining ingredients are added and the mass is mixed again. 17.0 g of the mixed mass is pressed hand-warm into a mold consisting of a Plexiglas tube with a diameter of 3.4 cm. The mass is pressed in the tube using two stamps to a height of 1.8 cm. After the mass has been pressed out, it is stored in the refrigerator for at least 24 hours and taken out of the refrigerator 30 minutes before the start of the experiment.
Ca. 5 min vor Versuchsbeginn wird die feste Masse halbiert und in das Glasrohr eingebracht. Dazu wird die Testmasse mit dem Kolben einer Einwegspritze in die enge Öffnung des Glasrohres eingeschoben, während von der anderen Seite desApproximately 5 minutes before the start of the test, the solid mass is halved and placed in the glass tube. To do this, the test mass is pushed into the narrow opening of the glass tube using the plunger of a disposable syringe, while
