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.
