Description

Verfahren zur Herstellung von Schutzüberzügen aus anorganischen Bindemitteln, wie Zement, Chlormagnesium, Wasserglas, auf mit einem bituminösen Überzug versehenen metallischen Werkstücken, insbesondere Eisenrohren Zur Erzielung einer verstärkten Schutzschicht auf metallischen Werkstücken, insbesondere Eisenrohren, hat man bereits die Verwendung von Zement, der z. B. mit Gewebestreifen auf das Rohr gewickelt wird, vorgeschlagen. Es bestand hierbei jedoch der Nachteil, daß eine Verbindung des Zements mit der Rohroberfläche nicht erreicht werden konnte, so daß bei rauher Behandlung insbesondere an denjenigen Stellen, woselbst Schwundrisse vorhanden waren, die Zementschicht abplatzen konnte. Außerdem war beim Aufbringen des Zementbreies das ungeschützte Rohr dem Einfluß der Feuchtigkeit unmittelbar ausgesetzt. Man empfahl daher auch, das Rohr vor dem Aufbringen der Zementschicht mit einer isolierenden Schicht aus Teer oder Bitumen zu versehen. Auf diesen glatten Oberflächen konnte jedoch der Zement einen noch geringeren Halt finden, so daß sich derartige Schutzschichten praktisch nicht einführen konnten.Process for the production of protective coatings from inorganic binders, such as cement, chlorine magnesium, water glass, on with a bituminous coating metallic workpieces, especially iron pipes To achieve a reinforced A protective layer on metallic workpieces, in particular iron pipes, is already in place the use of cement, e.g. B. is wrapped with strips of fabric on the pipe, suggested. However, there was the disadvantage that a compound of the cement with the pipe surface could not be reached, so that with rough treatment especially at those places where shrinkage cracks were present, the cement layer could flake off. In addition, when the cement slurry was applied, the one was unprotected Pipe directly exposed to the influence of moisture. It was therefore also recommended the pipe with an insulating layer before applying the cement layer To provide tar or bitumen. On these smooth surfaces, however, the Cement find an even lower hold, so that such protective layers practically could not introduce.

Diese Nachteile werden durch das Verfahren gemäß der Erfindung dadurch behoben, daß man, nachdem das zu schützende Werkstück mit einem Überzug aus Teer oder Bitumen versehen worden ist, vor dem Aufbringen der äußeren Schutzschicht aus anorganischen Bindemitteln, wie Zement, Chlormagnesium, Wasserglas, eine wässerige Teer-oder Bitumenemulsion aufträgt.These disadvantages are thereby exacerbated by the method according to the invention fixed that after the workpiece to be protected with a coating of tar or bitumen has been provided before the outer protective layer is applied inorganic binders, such as cement, magnesium chloride, water glass, an aqueous Applying tar or bitumen emulsion.

Auf diese Weise kann man metallische Werkstücke in jeder gewünschten Stärke mit einer Deckschicht aus anorganischen Bindemitteln, insbesondere Zement, versehen. Die Zwischenschicht aus einer «-ässerigen Teer-oder Bitumenernulsion ermöglicht eine feste Verbindung der Zementschicht auf dem Rohr bzw. auf der Grundschicht, und .zwar dadurch; daß die Emulsion in den Zementbrei mehr oderweniger tief eindringt. Die mechanische Widerstandskraft der Deckschicht gegen äußere Beanspruchungen wird bedeutend gesteigert und die Möglichkeit der Bildung von Schrumpfrissen auf ein Mindestmaß herabgesetzt, da die Zwischenschicht einen elastischen Träger für die Deckschicht darstellt.In this way you can have metallic workpieces in any desired shape Starch with a top layer of inorganic binders, in particular Cement. The intermediate layer made from a water-based tar or bitumen emulsion enables a firm connection of the cement layer on the pipe or on the base layer, and .through it; that the emulsion penetrates the cement paste more or less deeply. The mechanical resistance of the top layer to external stresses is significantly increased and the possibility of shrinkage cracks forming on a Reduced to a minimum, as the intermediate layer provides an elastic carrier for the Represents top layer.

Das Verfahren kann in verschiedenster 1'eise ausgeführt werden. Vorteilhaft ist es, las @Vcrksti.ick, z. B. das Röhr, in "escliniolzenes Bitumen oder in Teer zu tauchen und so niit einem Bitumen- oder: Teerüberzug auszuristen. -Nach dem Testwerden des Bitumen-oder "l'ceriil)erztiges bringt man in beliebiger «eise, z. B. durch Aufstreichen, Aufspritzen, Gießen oder Tauchen, eine wässerige Emulsion aus Bitumen oder Teer auf. Bevor diese Emulsionsschicht getrocknet ist, wird der Zementbrei in an sieh bekannter Weise z. B. durch Aufwickeln von mit Zementbrei getränkten Gewebestreifen oder durch * Aufspritzen aufgebracht.The method can be carried out in a wide variety of ways. Advantageous is it, las @ Vcrksti.ick, e.g. B. the pipe, in "escliniolzenes bitumen or in tar to dive and so not to be covered with a bitumen or tar coating. -After being tested The bitumen or l'ceriil) can be brought through in any way, for example Spreading, spraying, pouring or dipping, an aqueous emulsion of bitumen or tar on. Before this emulsion layer is dried, the cement paste becomes in a manner known per se z. B. by winding soaked with cement paste Tissue strips or applied by * spraying on.
