Abstract

UN MATERIAL SEPARADOR HIDROFILADO DE FIBRAS NO TEJIDAS PARA ACUMULADOR DE ENERGIA ELECTROQUIMICA CON ELECTROLITO ALCALINO ACUOSO SE COMPONE DE UNA MEZCLA DE FIBRAS DE POLIOLEFINA Y/O POLIAMIDA MUY Y POCO FUNDIDAS. EL MATERIAL DE VELO SE SOLIDIFICA EN FORMA FUNDIDA POR MEDIO DEL REBLANDECIMIENTO DE LA PORCION DE FIBRAS POCO FUNDIDAS A TRAVES DE PRESION Y CALENTAMIENTO, HUMEDECIENDOSE CON EL 0,5 HASTA 7% EN PESO CON RESPECTO AL PESO EN SECO DEL MATERIAL DE VELO CON AGUA DESIONIZADA. SE DA A CONOCER UN PROCESO PARA LA HIDROFILACION DEL MATERIAL DE VELO.
