Description

Verfahren zum überziehen der Innenwand von Gefäßen mit Schutzfilmen aus Lacken auf Basis flüchtiger Lösungsmittel Werden geschlossene Behälter, z. B. Druckflaschen, innen durch Ausschwenken mit Lacken behandelt, so stellt sich bei solchen Lacken, die leicht flüchtige Lösungsmittel, wie Sprit, enthalten, häufig heraus, daß der Überzug zum Teil nicht haftet.Process for covering the inner wall of vessels with protective films from paints based on volatile solvents. B. Pressure bottles, treated inside with varnish by swiveling them out, is what happens paints that contain volatile solvents such as gasoline are common found out that the coating is partly not adhering.

Gegenstand der Erfindung ist ein Verfahren, mit dem man eine gut ausgebildete Lackschicht in geschlossenen Behältern erhalten kann. Es ist gefunden worden, @daß man zu diesem Zweck. bereits während des langsamen Auslaufens der Lacklöls.umg aus dem Behälter in diesem eine gute Luftspülung oberhalb des sinkenden Spiegels der Lac'K-flüssiIgkeit schaffen muß, die bis zur Entleerung des Gefäßes fortgesetzt wird. Dies geschlveht beäspieL4veise bei Druckflaschen mit einer Anordnung, wie sie in der beiliegenden Zeichnung dargestellt ist.The invention is a method with which one well trained Paint layer can be obtained in closed containers. It has been found @ that one for this purpose. already during the slow draining of the varnish oil the container in this a good air purge above the falling level of the Lac'K fluid must create that continues until the vessel is emptied will. This is the case, for example, with pressure bottles with an arrangement such as it is shown in the accompanying drawing.

Nach dem Reinigen der Flasche wird diese, wie in der Abbildung angedeutet, vermittels eines Stahlbandos derart in einem' Lager befestigt, daß sie um. die AchseA-B -drehbar angeordnet ist, und zu etwa 3/4 mit Lacklösung gefüllt. In die öffnung der Flasche wird ein Gewindestopfen eingeschraubt, in welchem durch drei Bohrungen die Rohre i, 2 und 3 eingeführt sind. Durch Drehen um die Achse A-B wird bei .geschlossenen Rohren i, 2 und 3 die Flasche mehrmals umgedreht und in der in der Abbildung skizzi:erten Stellung festgehalten. Unmittelbar nachdem sich die Flasche in der skizzierten Lage befindet, muß -nach öffnen der Rohre i und 2 ein lebhafter Luftstrom, etwa aus einer Preßluftflasche, durch die Druckflasche geleitet werden. Dabei ist zu beachten, daß der Flüssigkeitsspiegel F der Lacklösung etwas unterhalb der Austrittsstelle der Luft aus denn Lufteinleitungsrohr liegt. Darauf wird der Abschlufhahn des Rohres 3 so geöffnet, daß dile Lacklösung .langsam aus der Druckflasche ausfließt. Nachdem die Lösung vollständig ausgelaufen ist - das Ende des Rohres 3 soll mit dem Gewindestopfen abschließen -, wird die Rohrleitung 2 geschlossen, .so das die Luft die Flasche unter Austritt aus der Ruhrleitung 3 durchspült.After cleaning the bottle, it is, as indicated in the figure, by means of a steel band in such a way in a 'camp that they are around. the axis A-B -Is arranged to be rotatable, and filled to about 3/4 with lacquer solution. In the opening A threaded stopper is screwed into the bottle, in which through three holes tubes i, 2 and 3 are inserted. Turning around the axis A-B closes the Pipes i, 2 and 3 turned the bottle several times and sketched it in the figure Position held. Immediately after the bottle is in the position outlined is, must -after opening the tubes i and 2 a lively air flow, for example from a Compressed air cylinder through which the pressure cylinder can be passed. It should be noted, that the liquid level F of the paint solution is slightly below the exit point the air is out of the air inlet pipe. Thereupon the shut-off valve of the pipe becomes 3 opened so that the paint solution slowly flows out of the pressure bottle. After this the solution has completely drained - the end of the tube 3 should be with the threaded plug complete -, the pipe 2 is closed, .so that the air the bottle flushed with exit from the Ruhr line 3.

Nach Abnahme des Gewindestopfens wird die Schidhit ordnungsgemäß eingebrannt und dieser Vorgang entsprechend der Betriebsvorschrift für Lacke zwei- bis dreimal wiederholt. Das Gewinde der Druckflaschenöffnung wird vor denn. letzten Einbrennen mittels eines Pinsels mit Lacklösung überstrichen.After removing the threaded plug, the Schidhit is properly burned in and this process two to three times in accordance with the operating instructions for paints repeated. The thread of the pressure bottle opening is before then. last burn-in Painted over with a paint solution using a brush.
