Rohre und Behälter aus glasfaserverstärktem Kunststoff und einer Auskleidung, zum Beispiel aus PTFEPipes and containers made of glass fiber reinforced plastic and a lining, for example made of PTFE
Rohre und Behälter werden oft aus glasfaserverstärktem Kunststoff hergestellt. Kommen sie mit aggressiven Medien in Berührung, so ist eine korrosionsfeste Auskleidung erforderlich. Diese erfolgt derart, daß die, zum Beispiel aus PVC, PTFE oder einem anderen Kunststoff bestehende Auskleidung, nach vorheriger Vorbereitung der Auskleidungsoberfläche durch mechanisches oder chemisches Aufrauhen - beisOxelsweise durch Ätzen - mit dem glasfaserverstärktem Kunststoff überzogen wird. Da jedoch Glasfasern die - für den vorliegenden Fall unangenehme - Eigenschaft besitzen, einen verhältnismäßig kleinen Wärmeausdehnungskoeffizienten zu haben, wird der glasfaserverstärkte Kunststoff bei Wärmeeinfluß an der Ausdehnung weitgehend gehindert. Dies bedeutet jedoch, daß sich wegen der unterschiedlichen Wärmedehnung des glasfaserverstärkten Außenmantels und der Folienauskleidung letztere oft ablöst. Das Verhältnis derPipes and containers are often made of glass fiber reinforced plastic. If they come into contact with aggressive media, a corrosion-resistant lining is required. This is done in such a way that the lining, for example made of PVC, PTFE or another plastic, is coated with the glass fiber reinforced plastic after prior preparation of the lining surface by mechanical or chemical roughening - in the case of oxels by etching. However, since glass fibers have the property, which is unpleasant in the present case, of having a relatively small coefficient of thermal expansion, the glass fiber-reinforced plastic is largely prevented from expanding when exposed to heat. However, this means that because of the different thermal expansion of the glass fiber reinforced outer jacket and the foil lining, the latter often becomes detached. The ratio of

glasfaserverstärktem Kunststoff, im v/eiteren kurz GFK genannt, zu Kunststoffen, wie zum BeisOiel PTFE liegt bei etwa 1:6· Dadurch bilden sich bei Rohren nach Wärmebeeinflussung, gewohnlich in der Nähe der Flansche, Falten aufgrund der Folienablösung.Bei Behältern treten derartige Ablösungen meist im Bereich der Behälterkanten auf.glass fiber reinforced plastic, in the front short GRP to plastics, such as PTFE at about 1: 6 Wrinkles due to film peeling. Step on containers such detachments usually occur in the area of the container edges.
Die Aufgabe der Erfindung besteht deshalb darin, bei Rohren und Behältern in Verbundbauweise aus GFK und einer im Inneren befestigten, zum Beispiel geklebten Folienauskleidung aus einem anderen Werkstoff, die Dehnung üfcer die gesamte Fläche gleichmäßig zu verteilen oder in bestimmten Bereichen der zu kaschierenden Flächen bewußte Dehnstellen vorzusehen.The object of the invention is therefore in pipes and containers in composite construction made of GRP and a inside attached, for example glued foil lining made of a different material, the expansion üfcer to distribute the entire surface evenly or consciously in certain areas of the surfaces to be concealed Provide expansion points.
Dies erfolgt erfindungsgemäß derart, daß die Befestigung nur in bestimmten, gleichmäßig über die Gesamtfläche verteilten Bereichen erfolgt. Auf diese Weise werden mehrere Dehnbereiche geschaffen und gleichmäßig über die Gesamtfläche verteilt. Jede Solldehnstelle für sich ruft nur eine geringe, praktisch nicht meßbare, in keinem Falle aber störende Entfernung der Folie von dem Grundwerkstoff hervor. So wird es zum Beispiel bei Rohren von geringerem Durchmesser ausreichen, die Folie nur streifenweise in Umfangsrichtung, also in Ringen, zu befestigen· In Umfangsrichtung erfolgt also eine volle Verklebung, da die Ausdehnung hier vernachlässigbar ist,According to the invention, this is done in such a way that the fastening is only carried out in certain, evenly over the entire area distributed areas. In this way, multiple stretch areas are created and evenly spread over the Total area distributed. Each desired expansion point in itself only causes a small, practically immeasurable, in no case but disturbing removal of the film from the base material. This is the case, for example, with pipes from smaller diameter are sufficient to attach the film only in strips in the circumferential direction, i.e. in rings. In the circumferential direction, there is a full gluing, since the expansion is negligible here,
' - 3 -309850/0731'- 3 -309850/0731
während die Längsdehnung sich auf die Bereiche zwischen den ringförmigen Verklebungen verteilt, also nicht störend auswirkt. Bei Behältern dagegen wird man die Befestigung et v/a nach Art eines Schachbrettmusters vornehmen, weil sich die Dehnung sonst in Längs- und in Querrichtung unangenehm bemerkbar machen· könnte»while the longitudinal expansion is distributed over the areas between the ring-shaped bonds, so it is not disruptive affects. In the case of containers, on the other hand, the fastening et v / a will be carried out in the manner of a checkerboard pattern, because otherwise the stretching could be uncomfortably noticeable in the longitudinal and transverse directions · »

A film 2 is glued into this. This gluing is however, it has not been carried out over the entire area, but only in rings, as is the case with the hatched areas 3 to illustrate.
In Figur 2 ist ein aus GFK bestehender Behälter mit if gekennzeichnet. In diesen Behälter ist eine Folie 5 eingeklebt. Auch diese Klebung erfolgte nicht vollflächig, sondern ebenfalls in gleichmäßig über die Gesamtfläche verteilten Bereichen, jedoch hier schachbrettartig.In FIG. 2, a container made of GRP is marked with if. A film 5 is glued into this container. These bonding did not occur over the entire surface, but also evenly distributed over the entire area, a checkerboard pattern but here.

Another possibility the only partial gluing of the container wall and the film is that, although initially the Total surface is prepared for gluing by roughening, but is covered before gluing.
