Abstract

PROCEDIMIENTO PARA OBTENER COMPUESTOS PARA PROTEGER EMPALMES DE CABLES POR ENCAPSULACION. EL MATERIAL CURABLE COMPRENDE AL MENOS UN ISOCIANATO, UN POLIOL, UN ESTER PLASTIFICANTE Y OPCIONALMENTE UNO O MAS DILUYENTES, TENIENDO EL MATERIAL UN TIEMPO DE CURADO DE POR LO MENOS 50 MINUTOS, APROXIMADAMENTE A 25JC. EL ENCAPSULANTE SE EMPLEA MEZCLANDO, EN EL PUNTO DE EMPALME, LOS COMPONENTES ANTERIORES, VERTIENDO EL ENCAPSULANTE EN UNA ENVUELTA DEL EMPALME, EN DONDE SE CURA IN SITU.
