"Schutzanordnung gegen den schädlichen Bewuchs von durch Schutzmittel gegen Korrosion geschützten Unterwasser-Stahlbauteilen" "Protective arrangement against the harmful growth of underwater steel components protected against corrosion by protective agents"
Die Erfindung betrifft eine Schutzanordnung gegen den schädlichen Bewuchs von durch Schutzmittel gegen Korrosion geschützten Unterwasser-Stahlbauteilen.The invention relates to a protective arrangement against the harmful growth of those protected against corrosion by protective means Underwater steel components.
Bekanntlich werden unter Wasser, insbesondere im Meerwasser, befindliche Bauwerke in relativ kurzer Zeit von Algen, Seepocken, Muscheln und dergl. Lebewesen bewachsen. In manchen Fällen können dadurch auch Rostschutzanstriche zerstört werden, was erhebliche Korrosionsschäden an Stahlbauteilen zur Folge hat.It is well known that structures located under water, in particular in sea water, are swept away by algae, barnacles, Overgrown on mussels and the like. In some cases this can also destroy anti-rust coatings, which results in considerable corrosion damage to steel components.
Abgesehen davon kann der Bewuchs auch zu einer Beeinträchtigung der Funktion der Stahlbauwerke führen, z.B. durch die Erhöhung des Fahrwiderstandes bei Schiffen.Apart from this, the vegetation can also impair the function of the steel structures, e.g. by raising them the driving resistance of ships.

Zur Verhinderung derartiger Bewuchsbildungen und der damit verbundenen Schaden ist es seit langem bekannt, Schutzanstriche auf den Unterwasser-Stahlbauteilen aufzubringen, die sogenannte Antifoulingwerkstoffe enthalten. Zu diesen zählen beispielsweise Kupfer- und Quecksilbersalze oder organische Kohlenwasserstoffverbindungen. Ihre Wirkung beruht darauf, daß sie von dem Wasser allmählich aus dem Schutzanstrich herausgelöst werden. Ihre Schutzwirkung hält jedoch nicht sehr lange an, so daß - oft nach etwa einem halben Jahr - der Bewuchs wieder einsetzt. Der Anstrich, der gleichzeitig dem Korrosionsschutz der Stahlbauteile dienen soll, muß dann erneuert werden, wofür die betreffenden Bauteile im allgemeinen aus dem Wasser gehoben werden müssen, was mit einem hohen Aufwand an Kosten und Zeit verbunden ist.To prevent such fouling and the damage associated therewith, it has long been known to use protective coatings to apply to the underwater steel components that contain so-called antifouling materials. These include for example copper and mercury salts or organic hydrocarbon compounds. Their effect is based on the fact that they are gradually dissolved out of the protective coating by the water. However, their protective effect does not last very long, so that - often after about half a year - the growth begins again. The paint, which is also the corrosion protection the steel components are to be used, must then be renewed, for which the components in question are generally lifted out of the water have to become, which is associated with a high expenditure of costs and time.
Es ist ferner bekannt, zum Korrosionsschutz für Stahlrohre und -konstruktionen diese mit einer relativ dickwandigen Ummantelung aus thermoplastischem Kunststoff, wie PVC oder Polyaethylen zu versehen. Beim Einsatz derartig beschichteter Bauteile im Meerwasser hat es sich jedoch gezeigt, daß auch deren Oberfläche von Seepocken, Muscheln und dgl. bewachsen wird. Es wäre möglich, die einen Bewuchs verhindernden toxischen Stoffe in dem Kunststoff einzulagern. Durch deren Herauslösen würde jedoch der Kunststoffmantel porig werden, wodurch dessen ansonsten zuverT lässiger Korrosionsschutz zerstört würde.It is also known to provide steel pipes and structures with a relatively thick-walled casing made of thermoplastic material, such as PVC or polyethylene, for corrosion protection. When components coated in this way are used in seawater, however, it has been shown that their surface is also overgrown by barnacles, mussels and the like. It would be possible to store the toxic substances that prevent fouling in the plastic. Through its dissolution, however, the plastic coating would be porous, causing its otherwise reli T would be destroyed permeable corrosion protection.
Die Erfindung hat sich zur Aufgabe gestellt, einen Langzeitschutz für Unterwasser-Stahlbauteile gleichzeitig gegen Korrosion und Bewuchs zu schaffen, mit welchem es ermöglicht wird, daß eine Erneuerung des Bewuchsschutzes erst nach einer Zeit von mehreren Jahren vorgenommen werden muß, ohne daß es hierfür erforderlich ist, die Teile aus dem Meerwasser zu heben, zu trocknen und neu anzustreichen.The invention has set itself the task of providing long-term protection for underwater steel components at the same time against corrosion and fouling, with which it is possible that a renewal the anti-fouling must only be carried out after a period of several years, without this being necessary is to lift the parts out of the sea water, dry them and repaint them.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß auf eineThis object is achieved according to the invention in that on a

die Oberfläche des Stahlbauteiles bedeckende elektrisch isolierende Schicht ein das Stahlbauteil ganz oder Teile desselben umschließendes metallisches Bewuchsschutzmittel angeordnet ist.the surface of the steel component covering electrically insulating Layer a metallic antifouling agent which completely or parts of the steel component is arranged.
Es wird mit der Erfindung fernerhin vorgeschlagen, daß die elektrisch isolierende Schicht aus einem organischen Kunststoff wie Polyaethylen und das metallische Bewuchsschutzmittel aus Kupfer oder einer Kupferlegierung in Form eines Drahtes, eines Bandes, einer Folie, eines Netzes, eines Anstrichs oder aufgespritzten Pulvers besteht.It is further proposed with the invention that the electrically insulating layer be made of an organic plastic such as polyethylene and the metallic antifouling agent made of copper or a copper alloy in the form of a wire, one Tape, foil, net, paint or sprayed on Powder.
Für den Korrosionsschutz wird vor allem eine Ummantelung aus einem thermoplastischem Kunststoff, insbesondere aus Polyaethylen empfohlen, die für Stahlrohre in bekannter Weise durch Extrudieren in Form eines dickwandigen Schlauches erzeugt wird. Für andere Stahlkonstruktionen können durch Spritzen oder Spachteln dickschichtige Lagen, vor allem aus Teerpech/Epoxyharz- oder Teerpech/Polyurethan-Massen auf jene aufgebracht werden. Hierbei ist lösungsmittelfreiem Teerpech/Epoxyharz der besseren chemischen Beständigkeit wegen und der größeren Härte der Vorzug zu geben. Diese Mantelschichten dienen bei der Verwendung von metallischem Kupfer als Antibewuchsmittel gleichzeitig als eine Isolation gegen Lokalelementbildung.For the protection against corrosion, a sheathing is mainly made a thermoplastic material, especially made of polyethylene, is recommended for steel pipes in a known manner by extrusion is produced in the form of a thick-walled tube. For other steel structures can be done by spraying or filling thick layers, especially of tar pitch / epoxy resin or tar pitch / polyurethane compounds, are applied to them. Here Solvent-free tar pitch / epoxy resin is the better chemical To give preference to resistance because of the greater hardness. These cladding layers are used when metallic ones are used Copper as an anti-fouling agent at the same time as an insulation against local element formation.
Durch das erfindungsgemäße Verfahren wird somit ein Schutzsystem geschaffen, daß aus einem organischen Korrosionsschutzmittel und einem getrennt davon wirkenden metallischen Bewuchsschutzmittel besteht.The inventive method thus creates a protection system that consists of an organic corrosion protection agent and a separate metallic antifouling agent.
