E<\/span><\/span>Le scellement \u00e9lectrique est utilis\u00e9 pour la liaison, l'\u00e9tanch\u00e9it\u00e9, l'encapsulation et la protection par rev\u00eatement des composants \u00e9lectroniques. <\/span><\/span>B<\/span><\/span>Avant la polym\u00e9risation<\/span><\/span>, c<\/span><\/span>le scellant est liquide et poss\u00e8de une fluidit\u00e9. La viscosit\u00e9 de l'adh\u00e9sif varie selon le mat\u00e9riau, les performances et le proc\u00e9d\u00e9 de fabrication du produit. Le produit d'\u00e9tanch\u00e9it\u00e9 ne r\u00e9alise sa valeur d'usage qu'apr\u00e8s polym\u00e9risation compl\u00e8te. Apr\u00e8s durcissement, il <\/span><\/span>offre les performances<\/span><\/span> of <\/span><\/span>d'\u00e9tanch\u00e9it\u00e9 \u00e0 l'eau, r\u00e9sistance \u00e0 l'humidit\u00e9, protection contre la poussi\u00e8re, isolation, conduction thermique, \u00e9tanch\u00e9it\u00e9 absolue, r\u00e9sistance \u00e0 la corrosion<\/span><\/span><\/span><\/b> et<\/span><\/span><\/span><\/b> r\u00e9sistance \u00e0 la temp\u00e9rature<\/span><\/span><\/span><\/b>. Il existe de nombreux types de scellants \u00e9lectroniques. <\/span><\/span>Par<\/span><\/span> type de mat\u00e9riau, on en distingue actuellement trois types les plus courants : le scellant \u00e0 base de r\u00e9sine \u00e9poxy,<\/span><\/span> le scellant silicone \u00e9lectrique<\/span><\/span>, et le scellant polyur\u00e9thane.<\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n

Le co\u00fbt de production du scellant silicone \u00e9lectrique est l\u00e9g\u00e8rement sup\u00e9rieur \u00e0 celui des autres types de scellants, mais il pr\u00e9sente <\/span><\/span>d'excellentes performances et une longue<\/span><\/span><\/span><\/b> p\u00e9riode d'application<\/span><\/span><\/span><\/b>, ce qui le rend particuli\u00e8rement adapt\u00e9 aux <\/span><\/span>op\u00e9rations de cha\u00eenes de production automatis\u00e9es en grande s\u00e9rie<\/span><\/span><\/span><\/b>. <\/span><\/span>Il peut \u00e9galement \u00eatre sp\u00e9cialement utilis\u00e9 pour le rev\u00eatement, le coulage et l'encapsulation protectrice des composants \u00e9lectroniques de pr\u00e9cision, de l'\u00e9nergie solaire, des r\u00e9tro\u00e9clairages et des modules \u00e9lectriques pour l'\u00e9tanch\u00e9it\u00e9 \u00e0 l'eau, la protection contre l'humidit\u00e9 et la pr\u00e9vention de la pollution gazeuse.<\/span><\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/p>\n

Il prot\u00e8ge les composants \u00e9lectriques contre l'humidit\u00e9 et la p\u00e9n\u00e9tration d'eau.

Il offre une meilleure conductivit\u00e9 thermique apr\u00e8s remplissage et modification avec des mat\u00e9riaux conducteurs de chaleur. L'utilisation de <\/font><\/span><\/span>e<\/span><\/span>silicone d'\u00e9tanch\u00e9it\u00e9 \u00e9lectrique peut efficacement am\u00e9liorer la capacit\u00e9 de dissipation thermique et la r\u00e9sistance \u00e0 l'humidit\u00e9 des composants \u00e9lectroniques, prolongeant ainsi la dur\u00e9e de vie des \u00e9quipements \u00e9lectroniques. De plus, <\/span><\/span>e<\/span><\/span>Le silicone d'\u00e9tanch\u00e9it\u00e9 \u00e9lectrique reste souple apr\u00e8s polym\u00e9risation, ce qui facilite la maintenance des \u00e9quipements \u00e9lectroniques. Le <\/span><\/span>produit d'\u00e9tanch\u00e9it\u00e9<\/span><\/span> peut s'auto-r\u00e9parer apr\u00e8s avoir \u00e9t\u00e9 fissur\u00e9 par une force externe<\/span><\/span> et <\/span><\/span>sans affecter <\/span><\/span>l'utilisation<\/span><\/span>. Compar\u00e9 au produit d'\u00e9tanch\u00e9it\u00e9 \u00e0 base de r\u00e9sine \u00e9poxy,<\/span><\/span> il pourrait<\/span><\/span> solliciter excessivement les composants \u00e9lectroniques<\/span>,<\/span> et pr\u00e9sente une moins bonne r\u00e9sistance aux intemp\u00e9ries<\/span><\/span> <\/span>provoque<\/span><\/span> de petites fissures <\/span><\/span>which<\/span><\/span> affecter l'\u00e9tanch\u00e9it\u00e9 \u00e0 l'humidit\u00e9 et la r\u00e9sistance \u00e0 la temp\u00e9rature<\/span><\/span>.
