Abstract

UNA ESPONJA ESTA FORMADA DE CELULOSA DESCRISTALIZADA, MODIFICADA POR SU CONTENIDO EN GRUPOS ACETILOS, SIENDO EL GRADO DE SUSTITUCION PROMEDIO DE 0,2 A 1,5. EN LA ESPONJA NO HAY NINGUN TIPO DE COMPOSICIONES DE AZUFRE NI ORGANICAS NI INORGANICAS. EL PROCEDIMIENTO DE FABRICACION COMIENZA CON EL TRATAMIENTO DE LA CELULOSA CON LEJIA DE SOSA Y CONTINUA CON EL TRATAMIENTO CON SUSTANCIAS DE EFECTO ACETILIZANTE, EL SECADO Y LA DISOLUCION EN UN DISOLVENTE ORGANICO CON ADICION DE UNA SAL FORMADORA DE POROS, FIBRAS Y OPCIONALMENTE COLORANTES PIGMENTARIOS, EL PRENSADO DE LA MEZCLA EN UNA FORMA PERFORADA CUYO VOLUMEN SE CORRESPONDA CON LAS DIMENSIONES DE LA ESPONJA A FABRICAR, LA INTRODUCCION DE LA FORMA CON CONTENIDO EN AGUA HIRVIENDO Y, FINALMENTE, LA EXTRACCION DE LA ESPONJA FORMADA EN LA FORMA.
