Abstract

SE FABRICA UN MATERIAL COMPUESTO DE FIBRAS DE CELULOSA POR UN METODO QUE COMPRENDE MEZCLAR ENTRE SI UNA RESINA PRE-POLIMERA DE UREA-FORMALDEHIDO QUE TIENE UNA ALTA RELACION MOLAR DE FORMALDEHIDO: UREA, UN MATERIAL DE FIBRRAS DE CELULOSA EN PARTICULAS Y UNA SOLUCION DE UREA. A CONTINUACION SE SOMETE LA MEZCLA A PRENSADO EN CALIENTE OBTENIENDO UN TABLERO DE FIBRAS CON BAJO CONTENIDO DE FORMALDEHIDO LIBRE PERO BUENA RESISTENCIA FISICA.
