Description

Behälter od.,dg1. aus Kunstharz, das z. B. aus einem Phenol-Formaldehyd-Kondensationsprodukt besteht, sind bekanntlich nicht gegen alle Chemikalien, z. B. Flußsäure, beständig. Es ist indessen bereits eine Spachtelmasse entwickelt worden, die innen auf die Wandungen der Behälter aufgebracht wird und diese nun auch gegen die Einwirkung von Flußsäure und Fluoride schützt. Eine derartige Spachtelung kann indessen nur da vorgenommen werden, wo die zu schützende Fläche mit dem Spachtelwerkzeug bearbeitet werden kann. Somit konnten Röhre u. dgl., die aus IZunstharzen über einem Dorn geformt werden, bis dahin nicht mit .der Spachtelmasse ausgekleidet werden.Container or, dg1. made of synthetic resin z. B. from a phenol-formaldehyde condensation product exists, are known not to be used against all chemicals, e.g. B. hydrofluoric acid, resistant. However, a filler has already been developed that can be applied to the inside of the Walls of the container is applied and these now also against the action protects from hydrofluoric acid and fluoride. Such a filling can only be be made where the surface to be protected is processed with the spatula tool can be. Thus, tubes and the like made of synthetic resins could be molded over a mandrel are not lined with the filler until then.

Gemäß der Erfindung ist diesem Nachteil abgeholfen, indem auf denDorn zunächst in gebräuchlicher Weise eine Schicht der Spachtelmasse aufgebracht wird, die dann. von der Phenol- oder Kresol-Formal.dehydmasse auf die bekannte Art umkleidet wird. Das fertige Rohr wird dann im Autoklav gehärtet.According to the invention, this disadvantage is remedied by putting on the mandrel first a layer of the filler is applied in the usual way, which then. encased by the phenol or cresol-formaldehyde mass in the known way will. The finished tube is then hardened in the autoclave.

In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt.The drawing shows an example embodiment of the subject matter of the invention shown.

Abb. i ist ein Längsschnitt und Abb: a .eine Ansicht des Rohres. Zwecks Herstellung eines Rohres aus Kunstharz wird bekanntermaßen ein Stahldorn a auf eine Drehbank gespannt, dessen Durchmesser oder lichten Weite des anzufertigenden Rohres entspricht. Auf diesen Dorn wird eine Masseschicht b angebracht, die gegen Flußsäure, Fluoride usw. beständig ist. Die Schicht b wird dann mit einer normalen Kunstharzumkleidung versehen, worauf beide Schichten zusammen in einem Autoklav gehärtet werden. Nach dem Aushärten der Kunstharzschichten wird der Dorn entfernt, und das Rohr ist gebrauchsfertig, wenn es nicht vorher noch lackiert oder sonstwie mechanisch bearbeitet werden soll.Fig. I is a longitudinal section and Fig: a. A view of the pipe. For the purpose of Production of a pipe made of synthetic resin is known to be a steel mandrel a Lathe clamped, its diameter or inside diameter of the pipe to be manufactured is equivalent to. A layer of mass b is applied to this mandrel, which is resistant to hydrofluoric acid, Fluoride etc. is resistant. Layer b is then covered with a normal synthetic resin coating provided, whereupon both layers are cured together in an autoclave. To the mandrel is removed after the resin layers cure and the pipe is ready for use, if it is not to be painted or otherwise mechanically processed beforehand.
