Description

Verfahren zum Verteilen von Lacken auf der Innenwandung von langen Hohlkörpern Bekanntlich macht das Lackieren von Hohlkörpern, insbesondere solchen mit engem Querschnitt, z. B. Rohren, insofern Schwierigkeiten, als es nach den bekannten Arbeitsweisen nicht gelingt, überall einen gleichmäßigen Lackfilm an bestimmter Stärke zu erzielen. Weder durch Anstreichen mit dem Pinsel noch mit der Spritzpistole ,oder durch Anwendung des Tauchverfahrens konnten hierbei bisher befriedigende Ergebnisise erzielt werden.Method of spreading paint on the inner wall of long Hollow bodies It is known that the painting of hollow bodies, especially those with a narrow cross-section, e.g. B. pipes, insofar as difficulties, as it is according to the known Working methods do not succeed, an even paint film on certain everywhere To achieve strength. Neither by painting with a brush nor with the spray gun , or by using the immersion process, this has so far yielded satisfactory results be achieved.

Auch die Verteilung der Lacke auf den Innenwandungen mit Hilfe von Verteilungsorganen, welche an :einer Zugstange, an Drähten o. dgl. durch das Rohr leindurchgeführt werden, führt nicht zum gewünschten Ziel, da die als Zugvorrichtungen dienenden Stangen oder Drähte beim Hinundherziehen mit den Rohrwandungen in Berührung kommen und die Lackschicht immer wieder heschädigen. Die Durchführung der Zugorgane durch Rohre in den üblichen Längen macht außerdem umständliche Vorrichtungen erforderlieh und ist sehr zeitraubend.Also the distribution of the paint on the inner walls with the help of Distribution organs, which on: a pull rod, on wires o. The like. Through the pipe be carried out, does not lead to the desired goal, as it acts as a pulling device serving rods or wires when pulled back and forth with the pipe walls in contact come and damage the paint layer again and again. Implementation of the traction organs tubes in the usual lengths also make cumbersome devices necessary and is very time consuming.

Es hat sich nun gezeigt, daß eine sehr gute und gleichmäßige Verteilung der Lacke in langgestreckten Hohlkörpern leicht in der Weise erzielt werden 'kann, daß erst auf die Innenwandungen Lack im überschuß aufgebracht wird, z. B. durch Tauchest oder Füllen gen Lack, und daß der. Röhre mit dem flüssig dann der Lach mit Hilfe von Verteilungsorgan z. B. durch Rundbürsten, Schwämme von entsprechender Form ioader ähnliche Hilfsmittel, verteilt und der überschußentfernt wird, indem diese Verteilungskörper abwechselnd von beiden Enden her mit Druckluft durch die Hohlkörper hindurchgetrieben werden. Durch diese Maßnahme wird nicht nur der überschuß des Lackes entfernt, sondern ,es gelingt .auch, durch geeignete Dimensionierung der Verteilungskörper gleichmäßige überzüge in jeder gewünschten Schichtdicke zu erzielen. Man kann auf diese Weise in außerordentlich kurzer Zeit die Innenwandungen großer Rohrlängen gleichmäßig mit Lack überziehen.It has now been shown that a very good and even distribution the lacquer in elongated hollow bodies can easily be achieved in such a way that that only on the inner walls paint is applied in excess, z. B. by Dip or fill varnish, and that the. Tube with the liquid then the laugh with the help of distribution organ z. B. by round brushes, sponges of the appropriate Form ioader similar tools, distributed and removed by this distribution body alternately from both ends with compressed air through the Hollow body are driven through. This measure will not only the Excess of the paint is removed, but, it works. Also, by suitable dimensioning the distribution body to uniform coatings in any desired layer thickness achieve. In this way, the inner walls can be removed in an extremely short time Coat large pipe lengths evenly with varnish.

Das Verfahren ist für die Erzeugung von gleichmäßigen überzügen sowohl auf blanken als auch auf rotbehandelten, z. B. pli-o@spliatierten Innemi-andungen von Rohren o. dgl. anwendbar. Es können alle beliebigen Lacke oder Farbanstriche nach dieser Arbeitsweise aufgebracht werden, ganz gleichgültig, welche Zusammensetzung sie haben und ob es sich um lufttrocknende oder um solche Überzüge handelt, die eingebrannt werden müssen. Die Konsistenz der flüssigen Lacke und Anstrichmittel wird so eingestellt, d,aß eine vollkommen 111 eichmäßibe Verteilung durch das Hindurch-@reilr, ii der Bürsten o. dgl. erreicht wird.The process is applicable to both the production of uniform coatings on bare as well as on red-treated, z. B. pli-o @ spliatierten innemi-andungen of pipes or the like. Applicable. Any varnish or paint can be used can be applied according to this procedure, regardless of the composition they have and whether they are air-drying or those coatings that need to be burned in. The consistency of liquid varnishes and paints is adjusted in such a way that it has a perfectly calibrated distribution through the passage, ii of the brushes or the like. Is achieved.
