Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA PRODUCCION DE PAPEL QUE CONSISTE EN AÑADIR A UNA SUSPENSION ACUOSA DE FIBRAS, QUE POSIBLEMENTE CONTIENE UNA SUSTANCIA DE RELLENO, AGENTES AUXILIARES PARA MEJORAR LA RETENCION Y/O DESHIDRATACION, EN DONDE LOS AGENTES AUXILIARES SON UNA POLIACRILAMIDA CATIONICA DE CADENA LARGA Y UNA SAL DE ALUMINIO, Y EN DESHIDRATAR LA SUSPENSION DE FIBRAS OBTENIDA DURANTE LA ETAPA DE FORMACION DE HOJAS. SEGUN LA INVENCION, A LA SUSPENSION ACUOSA DE FIBRAS ANTEDICHA, QUE POSIBLE,ENTE CONTIENE UNA SUSTANCIA DE RELLENO, A LA QUE SE HA AÑADIDO PRIMERO LA POLIACRILAMIDA CATIONICA DE CADENA LARGA, SE LE SOMETE A UNAS FUERZAS DE CIZALLAMIENTO, TRAS LO CUAL SE LE AÑADE, DIRECTAMENTE ANTES DE LA FORMACION DE LAS HOJAS, UNA SAL DE ALUMINIO POLIMERICA O UNA SAL DE ALUMINIO, EN CUYO CASO SE AÑADE UNA BASE O UN ACIDO, CUANDO SEA NECESARIO, A LA SUSPENSION DE FIBRAS ANTEDICHA PARA QUE EL PH SEA DE 7 A 9 ANTES DE FORMAR LAS HOJAS, EN CUYO CASO SE FORMARAN IN SITU PARTICULAS HIDROXI DE ALUMINIO CON UNAS CARGAS SUPERFICIALES ANIONICAS.THE INVENTION REFERS TO A PROCESS FOR THE PRODUCTION OF PAPER WHICH CONSISTS OF ADDING TO A WATER SUSPENSION OF FIBERS, WHICH POSSIBLY CONTAINS A SUBSTANCE OF FILLING, AUXILIARY AGENTS TO IMPROVE RETENTION AND / OR DEHYDRATION, IN DONDE LOS AXILI CATION OF LONG CHAIN AND ALUMINUM SALT, AND IN DEHYDRATING THE SUSPENSION OF FIBERS OBTAINED DURING THE LEAF FORMATION STAGE. ACCORDING TO THE INVENTION, TO THE AQUEOUS SUSPENSION OF FIBERS ABOVE, WHICH POSSIBLE, ENTE CONTAINS A FILLING SUBSTANCE, TO WHICH THE LONG CHAIN CATIONIC POLYACRYLAMIDE HAS BEEN ADDED FIRST, IS SUBJECT TO SOME SHEARING FORCES, WHICH ARE ADD, DIRECTLY BEFORE THE FORMATION OF THE LEAVES, A POLYMERIC ALUMINUM SALT OR AN ALUMINUM SALT, IN WHICH CASE A BASE OR AN ACID, WHEN NECESSARY, IS ADDED TO THE ABOVE FIBER SUSPENSION TO BE 7 9 BEFORE FORMING THE LEAVES, IN WHICH CASE ALUMINUM HYDROXY PARTICLES WITH ANIONIC ANIONIC SURFACE LOADS WILL BE FORMED IN SITU.
