Abstract

PROCEDIMIENTO PARA LA FABRICACION DE PAPEL UTILIZADO COMO CAPA INTERMEDIA DE LA CARTULINA PLISADA. BASADO EN LA UTILIZACION DE LOS LICORES NEGROS PARA EL REVESTIMIENTO DEL PAPEL DURANTE SU ETAPA DE SECADO, MEDIANTE RODILLOS O OTRO DISPOSITIVO ADECUADO. LOS LICORES NEGROS, A LOS QUE SE AÑADEN DE UN 0,2% A 0,3% EN PESO DE ALCOHOL POLIVINILICO, SE CONCENTRAN PREVIAMENTE POR LO MENOS AL 5%; LA RELACION ENTRE EL CONTENIDO EN MATERIA SECA DEL PAPEL Y DEL DE LOS LICORES NEGROS, DESPUES DE LA CONCENTRACION, ESTA ENTRE 50:10 Y 92:10. EL PAPEL UTILIZADO ES SEMIQUIMICO CON UN CONTENIDO EN PULPA DE MADERA INFERIOR AL 60% Y EL RESTO PULPA DE PAPEL RESIDUAL. SI EL PAPEL ES TOTALMENTE DE PULPA DE PAPEL RESIDUAL, LOS LICORES NEGROS SE DEBEN CONCENTRAR AL 30-50%.
