Abstract

SE REFIERE A UN METODO DE ELABORAR PRODUCTO DE PAPEL QUE COMPRENDA AGREGAR A LA PULPA HUMEDA: a) UNA POLIACRILAMIDA GLIOXALATADA, TAL COMO POLIACRILAMIDA CATIONICA, ANIONICA O ANFOTERICA GLIOXALATADA; Y b) UN OPACIFICADOR, TAL COMO ARCILLA, CARBONATO DE CALCIO PRECIPITADO, TiO2 Y SILICATO DE ALUMINIO. ASI SE FORMA UNA MEZCLA DE PULPA HUMEDA Y UN PRODUCTO DE PAPEL DE LA MEZCLA DE PULPA HUMEDA. SE PUEDE ELABORAR UN PRODUCTO DE PAPEL, PAPEL PERIODICO O PAPEL QUE CONTIENE MADERA CON UNA OPACIDAD DE POR LO MENOS 85%IT REFERS TO A METHOD OF PREPARING PAPER PRODUCT THAT INCLUDES ADDING TO THE WET PULP: a) A GLIOXALATED POLYACRYLAMIDE, SUCH AS GLYOXALATED CATIONIC, ANIONIC OR ANPHOTHERIC POLYACRYLAMIDE; AND b) AN OPACIFIER, SUCH AS CLAY, PRECIPITATED CALCIUM CARBONATE, TiO2 AND ALUMINUM SILICATE. THIS IS FORMING A WET PULP MIXTURE AND A PAPER PRODUCT FROM THE WET PULP MIXTURE. A PRODUCT CAN BE MADE FROM PAPER, NEWSPAPER OR PAPER CONTAINING WOOD WITH AN OPACITY OF AT LEAST 85%
