Abstract

L'ADDITION A POUR OBJET DES PERFECTIONNEMENTS AU PROCEDE ET A LA MACHINE DE TRAITEMENT D'UNE MATIERE PREMIERE CONTENANT DES FIBRES DE CELLULOSE. SELON L'ADDITION, ON REALISE LE DEFIBRAGE DE LA MATIERE EN AU MOINS DEUX ETAPES SUCCESSIVES, CHAQUE ETAPE COMPRENANT LE PASSAGE DE LA MATIERE DANS UNE ZONE D'ENTRAINEMENT ET UNE ZONE DE FREINAGE CONTROLANT LE PASSAGE SELECTIF VERS L'ETAPE SUIVANTE DE LA MATIERE AYANT ATTEINT UN DEGRE DE DEFIBRAGE CHOISI, CE DEGRE AUGMENTANT D'UNE ETAPE A LA SUIVANTE. DE PLUS, ON REALISE LE BLANCHIMENT DE LA PATE PAR INJECTION D'UN REACTIF DE BLANCHIMENT DANS LA MACHINE DE TRAITEMENT AU COURS DU PROCESSUS DE DEFIBRAGE. L'INVENTION S'APPLIQUE SPECIALEMENT A LA FABRICATION DE LA PATE A PAPIER A PARTIR DE COPEAUX DE BOIS.THE SUBJECT OF THE ADDITION IS TO IMPROVE THE PROCESS AND THE MACHINE FOR TREATING A RAW MATERIAL CONTAINING CELLULOSE FIBERS. DEPENDING ON THE ADDITION, THE DEFIBRATION OF THE MATERIAL IS CARRIED OUT IN AT LEAST TWO SUCCESSIVE STEPS, EACH STEP INCLUDING THE PASSAGE OF THE MATERIAL THROUGH A TRAINING ZONE AND A BRAKING ZONE CONTROL THE SELECTIVE PASSAGE TO THE NEXT STEP OF THE MATERIAL HAVING REACHED A SELECTED DEGREE OF DEFIBRATION, THIS DEGREE INCREASING FROM ONE STEP TO THE NEXT. IN ADDITION, BLEACHING OF THE DOUGH IS PERFORMED BY INJECTING A BLEACHING REAGENT INTO THE TREATMENT MACHINE DURING THE DEFIBRATION PROCESS. THE INVENTION SPECIFICALLY APPLIES TO THE MANUFACTURE OF PAPER PULP FROM WOOD CHIPS.
