Abstract

SE DESCRIBEN COMPOSICIONES Y METODOS PARA LA INHIBICION DE LA DEPOSICION DE CONTAMINANTES ORGANICOS DE LA PULPA EN LAS SUPERFICIES DE LA PULPA Y EN LOS SISTEMAS DE FABRICACION DE PAPEL. LA COMPOSICION ES UNA COMBINACION DE UN ALCOHOL POLIVINILICO CON HIDROLISIS ENTRE 50 Y 100 % Y UNA GELATINA DE ALTO PESO MOLECULAR QUE TIENE UN PESO MOLECULAR DE APROXIMADAMENTE 100.000 O SUPERIOR Y QUE SE AÑADE A LA PULPA O SE PULVERIZA SOBRE LAS SUPERFICIES DE LA PULPA Y DEL SISTEMA DE FABRICACION DE PAPEL. EN UNA REALIZACION PREFERIDA, SE DEMUESTRA EL SINERGISMO CON UNA PROPORCION EN PESO DE 8 A 1 ENTRE EL ALCOHOL POLIVINILICO Y LA GELATINA DE ALTO PESO MOLECULAR.
