Description

Bakterienfeste Korrosionsschutzschicht für Leitungsrohre oder Behälter E5 ist bekannt, daß bituminöse Massen nicht nui Eisenteile aller Art vor Korrosion schützen, sondert daß sie auch ein hervorragendes Isoliervermöger gegen Wasser zeigen, so daß bituminierte Eisenrohre und -behälter für Wasser oder wäßrige Lösungen voi einer Zerstörung bewahrt bleiben. Die Innenkorrosion von Wasserleitungsrohren kann durch eine Bitumenschutzschicht ebenfalls verhindert werden.Bacteria-resistant corrosion protection layer for pipes or containers E5 it is known that bituminous masses do not only protect iron parts of all kinds from corrosion protect, separate that they also show an excellent insulating capacity against water, so that bituminized iron pipes and tanks for water or aqueous solutions voi be preserved from destruction. The internal corrosion of water pipes can can also be prevented by a bitumen protective layer.

Es hat sich jedoch gezeigt, daß in vielen Fällen die L').itumenschcht nach einiger Zeit zerstört wird. Dabei wurde festgestellt, daß es sich um einen biologischen Abbau des Bitumens durch Bakterien handelt. Dieser Abbau tritt besonders häufig in Kläranlagen ein, wenn die Behälter und Rohre, die die Bitumenschutzschicht tragen, mit Abwässern, Schmutzwässern oder mit Faulschlamm gefüllt sind. Aber auch in Fällen, in denen die Bitumenschutzisolierung z. B. von feuchtem Humusboden berührt wird, können Bakterien einen uxydativen Abbau des Bitumens hervorrufen.It has been shown, however, that in many cases the L ') is destroyed after some time. It was found to be a Biodegradation of the bitumen by bacteria. This degradation occurs particularly often used in sewage treatment plants when the tanks and pipes that cover the bitumen layer are filled with sewage, dirty water or digested sludge. But also in cases where the bitumen protective insulation z. B. touched by moist humus soil bacteria can cause uxydative degradation of the bitumen.

Es wurde nun gefunden, daß ein Zusatz eines hochniolekularen Amins mit wenigstens einer langkettigen Alkylgruppe mit mindestens 8 C-Atomen zu den bitominösen Massen hervorragend geeignet ist, die Bakterien abzutöten und jeden biologischen Abbau de, Bitumens zu verhindern.It has now been found that the addition of a high molecular weight amine with at least one long-chain alkyl group with at least 8 carbon atoms to the bitominous Masses is excellently suited to kill the bacteria and any biological To prevent degradation of bitumen.

Es ist bereits bekannt, basische aromatische und lieterozyklische \T-Verbindungen, z. B. Pyridin, Cliinoli.n, Anilin, Naphthylamin usw., Farben und Lacken zuzusetzen, damit eine Alterung bzw. Polyinerisation der Farb- und Lackfilme vermieden wird.It is already known basic aromatic and lieterocyclic \ T connections, e.g. B. pyridine, Cliinoli.n, aniline, naphthylamine etc., colors and Adding varnishes to prevent aging or polymerisation of the paint and varnish films is avoided.

Es ist ferner bekannt, den bituminösen Mitteln, niit denen die »Pipe-Lines« überzogen werden, eine basische Aminkomponente zuzusetzen, die aber lediglich den Zweck hat, den pH-Wert auf 8 bis 10 zu stellen. Als basische Aminkomponenten sind z. B. genannt: Methylamin, Äthylainin, Propylamin, Äthanol- oder Propanolamine, Hydrazin, Anilin, Toluidin, Pyridin, Piperidin, Acridin usw. Diesen bituminösen lIitteln soll ferner ein fungizides und insektizide:s Mittel, z. 1'). Kupfer-Naphthenat, zugegeben werden.It is also known that the bituminous agents with which the "pipe-lines" are coated to add a basic amine component, but only the The purpose is to adjust the pH to 8 to 10. As basic amine components are z. B. named: methylamine, ethylamine, propylamine, ethanol or propanolamine, Hydrazine, aniline, toluidine, pyridine, piperidine, acridine etc. these bituminous A fungicidal and insecticidal agent is also to be used. 1'). Copper naphthenate, be admitted.

Der Zusatz organischer Kupfersalze oder gewisser Plienole ist schon verschiedentlich vorgeschlagen worden, um den Abbau des Bitumens zu unterbind-n, doch haben diese Zusätze nicht immer den gewünschten Erfolg gehabt.The addition of organic copper salts or certain plienols is nice Various proposals have been made to prevent the breakdown of bitumen, however, these additives have not always had the desired effect.

Beien Straßenbau ist die Verwendung hochinolekularer Amine als Zusatz zu bituminösen Mitteln bekannt, sie sollen bewirken, daß die I-Iaftfestigkeit der bituminösen Stoffe an feuchtem Gestein vergrößert wird. Bei trockner Oberfläche von Behältern und Rohren sind Haftmittel nicht notwendig, und die Fachwelt hat es bisher als völlig überflüssig betrachtet, einen solchen Haftvermittler zli verwenden, wenn inan z. ß. die Innenwand eines eisernen Behälter> niit einer Bitumenschutzschicht versieht oder wenn mau Eisenrohre bituminiert. Der Zusatz hochmolekularer. aliphatischer Amine, deren bakterizide Wirkung an sich bekannt ist, als Zusatz zu bituminösen Korros.ionsschutzschichten in Leitungsrohren und Behältern für Speisewasser, Abwässer, Schmutzwässer und Faulschlamm zur Verhinderung der Zerstörung durch Bakterien war nicht bekannt und wird hier zum ersten Male offenbart.In road construction, high molecular weight amines are used as additives known to bituminous agents, they are supposed to cause the Iaftigkeit the bituminous substances on moist rock is enlarged. With a dry surface Adhesives are not necessary on containers and pipes, and the experts have it previously considered completely superfluous to use such a bonding agent zli, if inan z. ß. the inner wall of an iron container with a bitumen protective layer provides or if the iron pipes are bituminized. The addition of high molecular weight. more aliphatic Amines, whose bactericidal effect is known per se, as an additive to bituminous ones Corrosion protection layers in pipes and tanks for feed water, waste water, Wastewater and digested sludge to prevent bacterial destruction not known and is here revealed for the first time.

Sowohl langkettige Alky lamme als auch quaternäre Ammoniumba.,en oder ihre Salze sind als Zusatz zu den bituminösen Mitteln geeignet. Auch Amine mit zwei- oder mehrbasischen Stickstoffatomen im Mol oder solche Alkylamine, die noch andere Gruppen, z. B. eine OH- oder C O O I-I-Gruppe im -Mol enthalten, zeigen sehr gute bakterizide Eigenschaften. Die Produkte sind schon in Mengen von etwa 0,01 bis 1%, bezogen auf das ßituinen, als Zusatz. in genügender Weise wirksam. E# können beispielsweise albakterizide Amine zur Verwendung koininen: Octvlamin C8 Hl; * 1' H2, Dodecy lamm Cl, H,25 * N H."

Amines with two or polybasic nitrogen atoms in the mole or those alkylamines which still have others Groups, e.g. B. contain an OH or C O O I-I group in the mol, show very good bactericidal properties. The products are already available in quantities of around 0.01 to 1%, based on the ßituinen, as an additive. sufficiently effective.
