Abstract

PROCEDIMIENTO PARA LA PREPARACION DE LAMINAS O PANELES PARA SEPARADORES DE BATERIAS DE ACUMULADORES DE ACIDO SULFURICO. SE OBTIENE UNA LAMINA QUE TIENE UN PESO ESPECIFICO DE 100-250 G/M A PARTIR DE UNA DISPERSION ACUOSA CONSTITUIDA POR UNA MEZCLA DE FIBRA DE CELULOSA CON FIBRILLAS DE AL MENOS UN POLIMERO OLEFINICO, EN UNA RELACION PONDERAL DE LAS PRIMERAS A LAS SEGUNDAS DE 20:80 A 40:60, DE 20 A 55% EN PESO, SOBRE PESO DE SOLIDOS, DE UN MATERIAL EN POLVO DE U TIPO DE MINERAL INORGANICO, CON UNA SOLUBILIDAD DE ACIDO SULFURICO AL 30% EN PESO, A LA TEMPERATURA DE 71<025>C Y TRAS UN TIEMPO DE RESIDENCIA EN DICHO ACIDO DE 27 HORAS, INFERIOR AL 5% EN PESO, 0 A 50% EN PESO DE FIBRAS DE VIDRIO CON UN DIAMETRO NO SUPERIOR A 15 MICROMETROS, DE 0 A 50% EN PESO DE UN POLIMERO DE VINILO O VINILIDENO Y DE 0,01 A 0,3% EN PESO DE UN AGENTE HUMECTANTE. SE SECA LA LAMINA O PAPEL Y SE CALIENTA, EN AUSENCIA TOTAL DE PRESION, A UNA TEMPERATURA IGUAL A LA TEMPERATURA DE FUSION DEL POLIMERO OLEFINICOQUE FORMA LAFIBRILLAS, PARA QUE FUNDA AL MENOS UNA PARTE DE DICHAS FIBRILLAS.
