Abstract
Description
Bakterizide Masse Die Erfindung bezieht sich auf bakterizide Schmiermittel und betrifft speziell bakterizide Schmiermittel, die bei der Montage von Rohrverbindungen für Wasserleitungen verwendbar sind. Bactericidal Composition The invention relates to bactericidal lubricants and specifically relates to bactericidal lubricants used in the assembly of pipe joints can be used for water pipes.
Bei der Verlegung und Reparatur von Wasserleitungen besteht die Neigung, daß Bakterien zu dem Inneren der Rohrleitungen Zutritt erhalten und danach das Wasser infizieren, das durch die Rohrleitung stromt. Eine neu verlegte oder reparierte Rohrleitung wird daher, bevor sie in vollen Betrieb genommen wird, im allgemeinen mit Wasser gespült, welches Chlor in hoher Konzentration enthält, um die Bakterien aus der Rohrleitung zu entfernen. Diese Behandlung hat zwar eine wirksame Sterilisation des Hauptteils der Rohrleitung zur Folge, sie entfernt Jedoch nicht in zufriedenstellender Weise -Bakterien aus den Verbindungen zwischen benachbarten Rohrlängen. Beispielsweise bei Verwendung von Eisenrohren mit durchströmten Bleiverbindungen, die mit Hanf gefüllt sind, infizieren in dem Hanf vorliegende Bakterien ständig das Wasser in der Rohrleitung, trotz aller Versuche, das Rohr unter Verwendung von Chlorwasser zu. sterilisieren.When laying and repairing water pipes, there is a tendency that bacteria gain access to the interior of the pipelines and then the water infect flowing through the pipeline. A newly laid or repaired one Pipeline is therefore generally used before it is put into full operation rinsed with water, which contains chlorine in high concentration, to remove the bacteria to be removed from the pipeline. This treatment does have an effective one sterilization of the main part of the pipeline, but not removed in a satisfactory manner Way bacteria from the connections between adjacent lengths of pipe. For example when using iron pipes with lead connections, those with hemp are filled, bacteria present in the hemp continuously infect the water in it the pipe, despite all attempts, the pipe using chlorinated water to. sterilize.
Diese Schwierigkeit wurde in jüngerer Zeit noch akuter durch die Einführung der sogenannten Steckverbindungen (push-fit joints). Die allgemeine Form dieser Verbindungen ist in der beiliegenden Zeichnung dargestellt, die im Querschnitt die Endteile von zwei Rohren 1 und 2 zeigt, die durch eine Steckverbindung 3 miteinander verbunden sind. Das Ende des Rohrs 1 besitzt erweiterten Durchmesser und tragt auf der Innenseite einen Kautschuk-Dichtungsring 4, der in geeigneter Weise durch eine Rille 5 oder ein anderes Mittel in seiner Lage gehalten wird. Zur Bildung der Verbindung 3 wird das Ende des#Rohrs 2 in das Ehde des Rohrs 1 eingeführt und durch den Dichtungsring 4 gedrückt, wodurch der Ring unter Bildung einer wasserundurbhlässigen Dichtung zusammengepre# wird.This difficulty has recently become more acute with the introduction the so-called push-fit joints. The general form of this Connections is shown in the accompanying drawing, which shows in cross section the Shows end parts of two tubes 1 and 2, which are connected to one another by a plug connection 3 are connected. The end of the tube 1 has an enlarged diameter and is bulky the inside of a rubber sealing ring 4, which is suitably by a Groove 5 or some other means is held in place. To form the connection 3 the end of the # tube 2 is inserted into the end of the tube 1 and through the sealing ring 4 pressed, causing the ring to form a water-tight seal is compressed.
Beim,Spülen einer Rohrleitung, ~die solche Steckverbindungen enthält, mit chloriertem Wasser, tretend Lufteinschlüsse in dem erweiterten Endteil Jedes Rohrs (das heißt in dem in der Zeichnung gezeigten Raum 6) auf und der Kontakt des sterilisierenden Wassers mit den Innenflächen d# Verbindung wird daher stark vermindert. Die Sterilisation ist infolgedessen häufig unvollständig und in diesen Räumen tritt daher anschließend Bakterienwachstum auf, wodurch das Wasser in dem Rohr infiziert wird.When flushing a pipeline containing such plug connections, with chlorinated water, entrapping air in the enlarged end part of each one Rohrs (i.e. in the space 6 shown in the drawing) and the contact of the sterilizing water with the inner surfaces d # connection is therefore greatly reduced. As a result, the sterilization is often incomplete and occurs in these rooms therefore bacterial growth subsequently occurs, thereby infecting the water in the pipe will.
Wie vorher beschrie#ben, wird bei der Derstellung einer Steckverbindung der Kautschukring und/Xier das durch den Ring zu schiebend Rohrende mit einem Schmiermittel überzogen, um die Herstellung der Verbindung zu erleichtern. Die bisher zu diesem Zweck verwendeten Schmiermittel haben den Nachteil, daß sie das Bakterienwachstum fördern oder daß sie die Desinfektion der Verbindung mit chloriertem Wasser aktiv behindern, indem sie eine physikalische.,Sperre bilden und/oder das Chlor absorbieren.As previously described, when creating a plug connection the rubber ring and / Xier that through the ring pipe end to be pushed coated with a lubricant to facilitate the connection. The lubricants used hitherto for this purpose have the disadvantage that they promote bacterial growth or that they disinfect the compound with chlorinated Actively impede water by creating a physical., Barrier and / or that Absorb chlorine.
Es wurde nun ein Schmiermittel entwickelt, welches ein Bakterizid enthält,und daher das Wachstum von Bakterien in der Verbindung im wesentlichen verringert oder verhindert. Dieses Schmiermittel behindert außerdem nicht die Desinfektion der Verbindung mit chloriertem Wasser.A lubricant has now been developed which is a bactericide and therefore substantially reduces the growth of bacteria in the compound or prevented. This lubricant also does not hinder disinfection the connection with chlorinated water.
Gegenstand der Erfindung ist daher eine Wasser und ein Verdickungsmittel enthaltende Masse, insbesondere ein wässriges Schmiermittel, welche ein Bakterizid und ein wasserlosliches Verdickungsmittel sowie Wasser enthält, wobei die Menge des Verdickungsmittels und des Wassers so gewählt ist, daß die Masse in Form einer Paste. eines Gels oder einer viskosen Flüssigkeit vorliegt.The invention therefore relates to a water and a thickener containing mass, in particular an aqueous lubricant, which is a bactericide and a water-soluble thickener and water, wherein the amount the thickener and the water is chosen so that the mass in the form of a Paste. a gel or a viscous liquid.
Durch die Erfindung wird ein Verfahren zum Zusammenbau einer Rohr-Steckverbindung zugänglich, bei dem auf eines oder beide der miteinander zu verbindenden Rohrenden das erfindungsgemäße wässrige Schmiermittel aufgetragen wird und die Rohrenden unter Bildung einer Steckverbindung ineinander gesteckt werden, Die bevorzugten Bakterizide sind wasserlösliche stickstoffhaltige Verbindungen, die ein fünfwertiges Stickstoffatom in Form einer quaternären Ammonium-, Pyridinium- oder Piperidinium-Gruppe aufweisen, in der das Stickstoffatom mit einer langkettigen Alkylgruppe mit 8 bis 18 Kohlenstoffatomen verbunden ist. Ein besonders bevorzugtes Bakterizid ist Cetyltrimethylammoniumbromid (Cetrimide). Zu anderen geeigneten Verbindungengehören Alkyldimethylbenzylammoniumchloride, Cetylpyridiniumchlorid, Dodecyldimethyl-2-phenoxy-äthyl-ammoniumbromid, 2,6-Dimethyl diäthylpiperidiniumbromid und die polymeren quaternären Verbindungen von Hexamethylen-bis-guanid (beispielsweise Vantocil I.B.).The invention provides a method for assembling a plug-in pipe connection accessible, in which on one or both of the pipe ends to be connected to one another the aqueous lubricant according to the invention is applied and the pipe ends under Forming a connector to be plugged into each other, the preferred bactericides are water-soluble nitrogen-containing compounds that have a pentavalent nitrogen atom in the form of a quaternary ammonium, pyridinium or piperidinium group, in which the nitrogen atom with a long chain alkyl group of 8 to 18 carbon atoms tied together is. A particularly preferred bactericide is cetyltrimethylammonium bromide (Cetrimide). Other suitable compounds include alkyldimethylbenzylammonium chlorides, Cetylpyridinium chloride, dodecyldimethyl-2-phenoxy-ethyl-ammonium bromide, 2,6-dimethyl diethylpiperidinium bromide and the polymeric quaternary compounds of hexamethylene bis-guanide (e.g. Vantocil I.B.).
Die Menge des Bakterizids in den Schmiermitteln ist vozugsweise relativ hoch und beträgt beispielsweise mindestens 10 Gew.-%, vorzugsweise etwa 20 Gew.-%, bezogen auf das Gewicht des Wassers. Mengen von weniger als 10 Gew.-%, beispielsweise 5 Gew.-% oder mehr (auf der gleichen Bezugsbasis) können verwendet werden, die Ergebnisse sind Jedoch weniger zufriedenstellend. Die relativ hohe Konzentration des Bakterizids ist erforderlich, weil bei der Bildung der Steckverbindung, nur -ein sehr geringer Anteil des Schmiermittels an dem Kautschukring vorbeitritt, während die Hauptmenge aus der Verbindung nach außen gedrückt wird.The amount of bactericide in the lubricants is preferably relative high and is, for example, at least 10% by weight, preferably about 20% by weight, based on the weight of the water. Amounts less than 10% by weight, for example 5 wt% or more (on the same basis of reference) can be used in the results however, are less than satisfactory. The relatively high concentration of the bactericide is necessary because when the connector is formed, only a very small amount Part of the lubricant on the rubber ring passes, while the main amount is pushed out of the connection.
Jedes geeignete wasserlesliche Verdickungsmittel kann verwendet werden, bevorzugte Materialien sind Jedoch wasserlösliche Celluloseäther, wie beispielsweise Methylcellulose, Hydroxypropylcellulose und Natriumcarboxymethylcellulose.Any suitable water-readable thickener can be used however, preferred materials are water-soluble cellulose ethers such as Methyl cellulose, hydroxypropyl cellulose and sodium carboxymethyl cellulose.
Die angewendete Menge des Verdickungsmittels (und Wasser) wird so gewählt, daß die Masse in Form- einer Paste, eines Gels oder einer viskosen Flüssigkeit vorliegt. Die in Jedem speziellen Fall erforderliche genaue Menge des, Verdickungsmittels schwankt in Abhängigkeit von den Arbeitsbedingungen, sie kann jedoch leicht durch einen Routineversuch bestimmt werden. Es wurde gefunden, daß bei Verwendung von 100 Gewichtsteilen Wasser etwa 5 Gewichtsteile Methylcellulose zufriedenstellend sind.The amount of thickener (and water) applied will be like this chosen that the mass is in the form of a paste, a gel or a viscous liquid is present. The exact amount of thickener required in each particular case varies depending on the working conditions, but it can easily change a routine attempt can be determined. It has been found that using 100 parts by weight of water about 5 parts by weight of methyl cellulose is satisfactory are.
Es wird bevorzugt, in den erfindungsgemäßen Massen destilliertes oder enthärtetes Wasser zu verwenden, diese Maßnahme ist Jedoch nicht wesentlich.It is preferred to use distilled water in the compositions according to the invention or However, using softened water is not essential.
Die vorstehend beschriebenen drei Komponenten der Schmiermittel sind wasserlöslich und werden daher ziemlich rasch von der Inneneeite der Verbindung weggespült. Sie führen daher zu keinerlei Vergiftungsgefahr oder verursachen keinerlei Geschmack und Geruch in den Wasserleitungen.The three components of the lubricant described above are water soluble and therefore get off the inside of the joint fairly quickly washed away. They therefore do not lead to any risk of poisoning or cause nothing Taste and smell in the water pipes.
Die erfindungsgemäßen Massen können außerdem enn Gefrierschutzmittel enthalten, wie Äthanol oder Propylenglykol, so daß kein Gefrieren der Massen bei 0° e eintritt. Bei Verwendung von etwa 10 bis 15 Gew.-% des Gefrierschutzmittels gefrieren die Massen nicht bei 100 C.The compositions according to the invention can also be antifreeze agents contain, such as ethanol or propylene glycol, so that the masses do not freeze 0 ° e entry. When using about 10 to 15% by weight of the antifreeze the masses do not freeze at 100 C.
Die Massen können außerdem ein wasserunlösliches Verdickungsmittel, wie Kieselsäure oder pulverförmiges Kunststoffmaterial enthalten. Dies ist vorteilhaft, wenn Eisenrohre mit großem Durchmesser von beispielsweise 700 mm verbunden werden sollen, wobei die Neigung besteht, daß durch das Gewicht der Rohre das Schmiermittel von den zu verblndenden Oberflächen weggedrückt wird, wenn nicht der Masse eine gewisse Menge eines wasserunlöslichen Verdickungsmittels zugesetzt wird.The masses can also contain a water-insoluble thickener, such as silica or powdered plastic material. This is beneficial when connecting iron pipes with a large diameter of, for example, 700 mm should, with the tendency that the weight of the pipes, the lubricant is pushed away from the surfaces to be veneered, if not one of the mass a certain amount of a water-insoluble thickener is added.
Die erfindungsgemäße Masse kann verpackt und unbegrenzt lange gelagert werden oder sie kann auch unmittelbar vor der Verwendung hergestellt werden, indem beispielsweise eine geeignete Menge Wasser zu einem vorgebildeten Gemisch aus dem Bakterizid und dem Verdickungsmittel zugesetzt, wird.The composition according to the invention can be packaged and stored for an unlimited period of time or it can also be prepared by immediately prior to use for example a suitable amount of water to a pre-formed mixture of the Bactericide and added to the thickener.
Zum besseren Verständnis der Erfindung wird das folgende, lediglich zur Veranschaulichung dienende Beispiel. gegeben.In order to better understand the invention, the following is provided only illustrative example. given.
Beispiel Ein Schmiermittel wurde durch Auflösen von 20 Gewichtsteilen Cetyltrimethylammoniumbromid und 5 Gewichtsteilen Methylcellulose in 100 Gewichtsteilen Wasser hergestellt. Das Schmiermittel lag in Form eines Gels vor. Bei der Verwendung zeigte es sehr zufriedenstellende Wirkungen.Example A lubricant was prepared by dissolving 20 parts by weight Cetyltrimethylammonium bromide and 5 parts by weight of methyl cellulose in 100 parts by weight Water produced. The lubricant was in the form of a gel. When using it showed very satisfactory effects.
