Description
Verfahren zum Innenanstrich unzugänglicher Räume Es ist bekannt, Rohre in der Weise mit einem rostschützenden Innenüberzug aus Metall zu versehen, daß ein mit erhitzter Preßluft vermischter Metallnebel hindurchgeleitet wird. Dieses Verfahren ist jedoch nur für einzelne kurze Rohrstücke verwendbar.Method for interior painting of inaccessible spaces It is known, pipes to be provided in such a way with a rust-proof inner coating made of metal that a metal mist mixed with heated compressed air is passed through. This However, the method can only be used for individual short pieces of pipe.
Ferner ist bekannt, die Innenflächen von fertig verlegten Gasleitungen mit einem Ölfilm dadurch zu überziehen, daß man in die Leitungen mit Hilfe von Preßgas einen Ölnebel hineinbläst. Es gelingt dies um so besser, je feiner der Nebel und je rascher die Bewegung des Gasstromes ist.It is also known that the inner surfaces of gas lines that have already been laid to be covered with an oil film, that one in the lines with the help of compressed gas blows in an oil mist. This succeeds the better, the finer the mist and the faster the movement of the gas stream.
Ebenso bekannt ist es aber, daß eine Ölung an und für sich keinen genügenden Rostschutz ergibt, weil das Öl namentlich in dünner Schicht nicht genügend wasserundurchlässig und nicht genügend gasundurchlässig ist, um die Korrosionen zu verhindern.It is just as well known, however, that an unction in and of itself does not have any results in sufficient rust protection, because the oil is not enough, especially in a thin layer impermeable to water and not sufficiently gas impermeable to prevent corrosion to prevent.
Die neue Erfindung besteht nun darin, daß man statt eines Ölnebels einen Nebel aus einer an sich bekannten Lösung von Mineralöl und Asphalt oder von Mineralöl und hochviskosen Fetten, wie Wollfett u. dgl., erzeugt und in die sonst unzugänglichen Räume, die mit Spritz- und Streichwerkzeugen nicht erreichbar sind, einbläst. Statt dieser Lösungen können auch andere Anstrichmittel verwendet werden, die homogen genug sind, um sie nebelartig zerstäuben zu können.The new invention consists in the fact that instead of an oil mist a mist of a known solution of mineral oil and asphalt or of Mineral oil and highly viscous fats, such as wool fat and the like, produced and in the otherwise inaccessible spaces that cannot be reached with spraying and painting tools, blows in. Instead of these solutions, other paints can also be used, which are homogeneous enough to be able to atomize them like a mist.
Das Zerstäuben geschieht am besten mit den an sich bekannten Zerstäubungsapparaten und das Einbringen des so hergestellten Nebels der beschriebenen Lösung durch ein Preßgas irgendwelcher Art.The atomization is best done with the atomizing apparatus known per se and the introduction of the mist thus produced of the solution described by a Compressed gas of any kind.
Dem Luft- oder Gasstrom wird eine genügend große Geschwindigkeit gegeben, damit der Nebel so weit getragen wird, daß er zu den zu schützenden Flächen gelangt. Auch wird die Temperatur des Nebels so eingerichtet, daß er sich durch Kondensation auf den Flächen niederschlägt.The air or gas flow is given a sufficiently high velocity so that the fog is carried so far that it reaches the surfaces to be protected. Also the temperature of the mist is adjusted so that it can be removed by condensation precipitates on the surfaces.
Die Flächen werden dadurch nicht nur mit Ölung, sondern mit einem wirklichen Anstrich überzogen, der nicht abläuft und der eine dichte, gegen Wasser und Gas zuverlässig abschließende Decke ergibt, vorausgesetzt, daß das Einblasen des Nebels genügend lange Zeit fortgesetzt wird. Bei dem Einblasen des Nebels z. B. in Gasbehälter wird zweckmäßig so verfahren, daß der Zu- und der Abgangsschieber des Gasbehälters geschlossen wird. In ein nach demEingangsschieber einzubauendes Nebenventil wird das beschriebene Anstrichmittel in Nebelform eingeblasen. Aus einem vor dem geschlossenen Ausgangsschieber angebrachten Nebenventil wird gleichzeitig Gas abgezogen, komprimiert und wieder zum Einblasen des Nebels verwendet.The surfaces are not only oiled, but with a real paint coated, which does not run off and the one dense, against water and gas provides a reliable sealing ceiling, provided that the injection the fog continues for a long enough time. When blowing in the mist z. B. in gas container is expediently proceeded so that the inlet and outlet slide the gas container is closed. In one to be installed after the inlet slide Secondary valve, the paint described is blown in in the form of a mist. From a The secondary valve installed in front of the closed outlet slide is switched on at the same time Gas withdrawn, compressed and reused to blow the mist.
Auf diese Weise entsteht durch den Gasbehälter hindurch die Zirkulation eines Anstrichmittelnebels, der sich an den Gasbehälterwänden und Decken niederschlägt und diese mit einer dichten Schutzschicht überzieht.This creates circulation through the gas container a paint mist that settles on the gas container walls and Ceilings precipitate and cover them with a thick protective layer.
Sinngemäß ist es auch möglich, andere Röhrensysteme oder allgemein unzugängliche Räume durch Hindurch- oder Einführen eines mit der beschriebenen Lösung hergestellten Nebels mit einer inneren Schutzschicht zu überziehen. Bei der Herstellung von Rohrleitungen, insbesonderesolchen mit geschweißten Verbindungen, ist eine solche nachträgliche Aufbringung einer gleichmäßigen inneren Schutzschicht in der fertig verlegten Rohrleitung die einzige Möglichkeit, um die Korrosionsgefahr zu beseitigen.Similarly, it is also possible to use other tube systems or in general inaccessible spaces by passing through or introducing one with the solution described to cover the produced mist with an inner protective layer. In the preparation of of pipelines, especially those with welded connections, is one subsequent application of a uniform inner protective layer in the finished laid pipeline is the only way to eliminate the risk of corrosion.
