Abstract

SE TRATA DEL DESARROLLO DE UN SISTEMA PARA EL PROCESO DE FABRICACION DE PAPEL, QUE CONSISTE EN FORMAR Y DESHIDRATAR DISPERSION DE FIBRA/ACUOSA (44) POR DRENAJE SUMERGIDO EN EL QUE NO PENETRA LA DISPERSION FIBRA/ACUOSA (44) NI LA MEMBRANA DE PAPEL AL FORMARSE; LA DESHIDRATACION SE CONSIGUE MEDIANTE LA ALTERACION DE LA TENSION NATURAL DEL MENISCO DEL AGUA DE MANERA QUE INDUCE EL AUMENTO DEL DRENAJE DEL AGUA DE LA DISPERSION ACUOSA (44) DE LAS FIBRAS UTILIZADAS PARA LA FABRICACION DEL PAPEL, PRINCIPALMENTE EN EL EXTREMO MAS MOJADO DEL SISTEMA.IT IS ABOUT THE DEVELOPMENT OF A SYSTEM FOR THE PAPER MANUFACTURING PROCESS, WHICH CONSISTS OF FORMING AND DEHYDRATING FIBER / AQUEOUS DISPERSION (44) BY SUBMERGED DRAINAGE IN WHICH NO FIBER / WATER DISPERSION (44) OR PAPER MEMBRANE WHEN FORMING; DEHYDRATION IS ACHIEVED BY ALTERING THE NATURAL TENSION OF THE WATER MENISCO IN A WAY THAT INDUCES THE INCREASE OF WATER DRAINAGE FROM AQUEOUS DISPERSION (44) OF THE FIBERS USED FOR THE MANUFACTURE OF PAPER, MAINLY IN THE EXTREMELY MOST WET. .
