Abstract

SE DESCRIBE UNA LAMINA FLEXIBLE POROSA DE ALREDEDOR DE 96,5 AL 99,5 POR CIENTO EN PESO DE SILICE PRECIPITADA AMORFA Y DE ALREDEDOR DEL 0,5 A APROXIMADAMENTE EL 3,5 POR CIENTO EN PESO DE POLIMERO NO SINTERIZADO, FIBRILADO, POR EJEMPLO, POLITETRAFLUOROETILENO. LA LAMINA ES UTIL COMO SEPARADOR EN BATERIAS RECOMBINANTES DE ELECTROLITO ABSORBIDO Y GAS, POR EJEMPLO, BATERIAS DE PLOMO-ACIDO. LA LAMINA SE PREPARA SOMETIENDO UNA MEZCLA SECA DE LA SILICE Y EL MATERIAL POLIMERO, POR EJEMPLO, POLITETRAFLUOROETILENO, EN LAS PROPORCIONES ANTERIORES, A FUERZAS DE MEZCLADO CON CIZALLAMIENTO MECANICO PARA FIBRILAR EL POLIMERO Y CONFORMANDO EN SECO SEGUIDAMENTE LA MEZCLA RESULTANTE EN FORMA DE LAMINA.
