Description
<EMI ID=1.1> <EMI ID=2.1> pour le moins on obtenait des couches métalliques adhérant très mal.. Suivant la présente invention, on obvie à ces inconvé- <EMI ID=3.1> appliquée en solution aqueuse et séchée. Cet enduit a pour effet, de Manière analogue à un enduit de vernis, d'augmenter notablement la résistance d'isolement du diélectrique. Tout comme lorsqu'on emploie des vernis, on peut aussi réaliser une augmentation supplémentaire de la résistance au percement électrique et de la résistance d'isolement de la matière diélectrique en appliquant plusieurs couches de méthyl-cellulose. Les couches ultérieures peuvent être plus minces que la couche appliquée la préfère. Quand, vue imprégnation subséquente du ruban de papier <EMI ID=4.1> <EMI ID=5.1> <EMI ID=6.1> absolue est assurée tant oendant la fabrication de la solution aqueu-- <EMI ID=7.1> <EMI ID=8.1> seulement au cours de la fabrication de la solution de vernis, !:lais encore au cours du travail ultérieur, des précautions et dispositifs spéciaux relevant de la technique de la protection contre le feu, qui deviennent superflu quand on emploie la méthyl-cellulose. REVENDICATIONS S <EMI ID=9.1> fabriquer des matières diélectriques, notamment du papier servant de support de métallisation, caractérisé en ce que l'enduit isolant, remplissant les pores et cavités de la surface de la matière diélectrique, est constitué de méthyl-cellulose appliquée en solution aqueuse et séchée.
