Abstract

L'invention concerne un revêtement de protection destiné à être utilisé sur des bateaux de haute mer dont la coque est en acier et travaillant sur les mers chaudes et les océans. Le revêtement se présente sous la forme d'un film magnétique détachable dont l'épaisseur est comprise entre 0,8 et 1,2 mm. Le film est obtenu selon un procédé de soudage par couches ou de collage des couches. Le film comprend les composants suivants placés les uns au-dessus des autres : une couche magnétique, une couche diélectrique, une couche électroconductrice et une couche externe résistant à l'usure. La couche magnétique est constituée d'un vinyle magnétique, la couche diélectrique est constituée de polyéthylène, la couche électroconductrice est constituée de cuivre ou d'aluminium et la couche résistant à l'usure est constituée de caoutchouc. La couche électroconductrice du film multicouche est pourvue de bornes électriques destinées à être raccordées à une source de courant embarquée externe. Cette invention permet de maintenir le revêtement de protection sur la coque du bateau et de le retirer rapidement après souillure marine en utilisant les forces d'Ampère qui génèrent l'attraction ou la répulsion des deux conducteurs parallèles étroitement espacés en fonction du sens d'écoulement du courant dans ceux-ci.
