Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CARTON PRENSADO RESISTENTE A ELEVADAS TEMPERATURAS, CON UNA COMBINACION CONVENIENTE DE VALORES DE COMPRESION PERMANENTE Y ABSORCION DE ACEITE. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE FORMA UN SUSPENSION ACUOSA QUE CONTIENE ENTRE UN 0,1 Y UN 2% EN PESO DE SOLIDOS TOTALES, QUE ESTAN CONSTITUIDOS POR UN 20 A UN 95% EN PESO DE FIBRAS DE UNA POLIAMIDA AROMATICA Y POR UN 80 A UN 5% EN PESO DE UN FLOCULO RESISTENTE A TEMPERATURAS ELEVADAS; SEGUNDA, SE CONFIGURA LA SUSPENSION EN FORMA DE PAPEL SIN ENGOMAR, CON UN CONTENIDO EN AGUA ENTRE UN 50 Y UN 95% DEL PESO DEL PAPEL SIN ENGOMAR; TERCERA, SE COMBINA EL PAPEL SIN ENGOMAR EN MULTIPLES CAPAS PARA FORMAR UNA NAPA HUMEDA; CUARTA, SE PRENSA LA NAPA HUMEDA PARA FOMAR UN CARTON PRENSADO DE BAJA DENSIDAD; Y POR ULTIMO, SE SECA EL CARTON PRENSADO DE BAJA DENSIDAD HASTA QUE NO SE DESPRENDA HUMEDAD.
