Abstract
(DE)
Die Erfindung betrifft eine Zusammensetzung zur Verhinderung / Verringerung der Mikroben-induzierten Biokorrosion durch Sulfat-reduzierende Bakterien (SRB) und andere Mikroorganismen, insbesondere zum Schutz von Innenwänden von Lagertanks für Kohlenwasserstoffe aller Art. Die Aufgabe der Erfindung, eine Zusammensetzung bereitzustellen, die bei ihrer Verwendung als Korrosionsschutzmasse besonders effektiv Mikrorisse in Beschichtungen von Innenwänden von Lagertanks für Kohlenwasserstoffe aller Art durch einen lokal begrenzten aktiven Schutzmechanismus (Depotwirkung) möglichst lange vor anaerober Biokorrosion schützt, wird dadurch gelöst, dass die Zusammensetzung mindestens ein epoxidbasiertes, polymeres, vernetztes, Al2O3-Keramikpartikel-enthaltendes Substrat und ein mikrobistatisch wirksamen Pyrithion-Derivat umfasst.
(EN)
The invention relates to a composition for the prevention/reduction of microbe-induced bio-corrosion caused by sulfate-reducing bacteria (SRB) and other microorganisms, especially for the protection of the inner walls of storage tanks for hydrocarbons of all kinds. The aim of the invention is to devise a composition which protects, when used as a corrosion protection compound, microcracks in the coatings of the inner walls of storage tanks for hydrocarbons of all kinds from anaerobic bio-corrosion in an especially effective manner and for as long a period as possible, owing to a locally defined active protection mechanism (depot effect). The composition comprises an epoxy-based, polymeric, cross-linked Al2O3 ceramic particle-containing substrate and a microbistatically effective pyrithione derivative.
(FR)
La présente invention concerne une composition pour empêcher / réduire la biocorrosion d'origine microbienne due à des bactéries sulfato-réductrices (SRB) et à d'autres micro-organismes, en particulier pour protéger les parois intérieures de réservoirs de stockage d'hydrocarbures de tous types. L'invention a pour objet la mise à disposition d'une composition qui, lorsqu'elle est utilisée en tant que masse anticorrosion, protège de la biocorrosion anaérobie, de manière particulièrement efficace et pendant une durée prolongée, des micro-fissures présentes dans des revêtements de parois intérieures de réservoirs de stockage d'hydrocarbures de tous types, par un mécanisme de protection actif limité localement (effet de dépôt). A cet effet, la composition comprend au moins un substrat polymère réticulé à base époxyde, contenant des particules céramiques Al2O3, et un dérivé de pyrithione à action microbiostatique.
