Abstract

L'invention porte sur un procédé permettant d'empêcher l'apparition, durant le traitement d'un matériau en feuille, d'un arc électrique localisé vers la terre dans le champ d'une décharge par effet de couronne produit par un appareil à décharge par effet de couronne, comportant deux électrodes au moins. Le procédé consiste à faire passer le matériau en feuille à traiter dans un champ de décharge par effet de couronne, ledit matériau étant isolé des électrodes. Lorsque l'appareil à décharge par effet de couronne possède une électrode en métal nu et une électrode recouverte d'un matériau diélectrique, on fait passer le matériau en feuille à traiter dans le champ de décharge par effet de couronne ce matériau se présentant sous la forme d'une couche d'un matériau composite multicouches comportant trois couches au moins, l'une au moins de ces couches, une feuille non conductrice, se trouvant entre le matériau en feuille à traiter et l'électrode de métal nu. On peut faire appel à ce procédé pour traiter un matériau en feuille hydrophobe poreux en faisant alors passer ledit matériau dans un champ de décharge par effet de couronne produit par un appareil à décharge par effet de couronne possédant une électrode en métal nu et une électrode recouverte d'un matériau diélectrique dans des conditions propices à rendre la feuille poreuse humidifiable. Ce matériau en feuille hydrophobe est une couche non conductrice d'un matériau composite multicouches comportant trois couches au moins, l'une d'elles, au moins, étant une feuille non conductrice se trouvant entre le matériau en feuille à traiter et l'électrode de métal nu tandis que l'une au moins des trois couches étant une feuille non conductrice et non poreuse.
