Abstract

LAS RESINAS DE FORMALDEHIDOS DE UREA CATIONICAS SE OBTIENEN MEDIANTE LA CONDENSACION DE LA UREA Y DEL FORMALDEHIDO EN UNA RELACION MOLAR DE 1:1,5 A 3 ANTE LA PRESENCIA DE AL MENOS 1 MOL% DE POLIMERIZADOS, OBTENIDOS MEDIANTE LA POLIMERIZACION DE UNIDADES DE VINILAMINA, CON VALORES K SEGUN FIKENTSCHER DE 5 A 300 EN UNA CANTIDAD DE 5 A 100 G/MOL DE UREA EN EL PRODUCTO FINAL. LA MEZCLA SE A) PRECONDENSA PRIMERO A UN PH DE 8 A 14, DESPUES SE ACIDIFICA Y B) SE CONDENSA A UN PH DE 1 A 5 HASTA QUE EMPIEZA A FORMARSE UN GEL, C) SE AÑADEN DE UN 0,3 A UN 1,5 MOLES DE FORMALDEHIDO POR MOL DE UREA UTILIZADO, D) A CONTINUACION SE LLEVA A CABO UNA CONDENSACION Y E) SE NEUTRALIZA ENTONCES LA SOLUCION DE RESINA. LAS RESINAS ASI OBTENIDAS SE UTILIZAN COMO ADITIVOS EN LA FABRICACION DE PAPEL PARA AUMENTAR LA RESISTENCIA EN ESTADO SECO Y HUMEDO DEL PAPEL PARA REDUCIR LA PERDIDA DE LA OPACIDAD DE LA BLANCURA DEL PAPEL.
