Abstract

PARA PRODUCIR SOLUCIONES ACUOSAS DE CELULAS EN OXIDOS AMINICOS TERCIARIOS, SE CALIENTA UNA SUSPENSION DE CELULOSA EN DISOLUCIONES ACUOSAS DE OXIDOS AMINICOS TERCIARIOS A PRESION REDUCIDA, PARA OBTENER UNA SUSPENSION CON UNA VISCOSIDAD ENTRE 50 Y 15.000 PAS. SEC MEDIDO EN UN SISTEMA RELATIVO; SE EXTIENDE DICHA SUSPENSION SOBRE LA SUPERFICIE O CAPA CALIENTE Y SE TRANSPORTA HASTA OBTENER UNA SOLUCION HOMOGENEA DE CELULOSA. EL SUMINISTRO DE SUSPENSION Y LA CALIDA DE SOLUCION HOMOGENEA SE REALIZA DE FORMA CONTINUA. LA SOLUCION PUEDE PRODUCIRSE EN UN RECIPIENTE EVACUABLE QUE ESTA EQUIPADO CON UN DISPOSITIVO AGITADOR Y CALENTABLE INDIRECTAMENTE. EL RECIPIENTE SE CONFORMA COMO DEPOSITO CILINDRICO (2) CON UNA TRANSMISION (7) PARA EL AGITADOR SITUADA CENTRALMENTE EN EL RECIPIENTE Y CON UNA PALA (8) DEL AGITADOR ASENTADA EN LA TRANSMISION. LA DISTANCIA (13) RADIAL DE LA PALA (8) DEL AGITADOR A LA PARED INTERIOR (1) DEL DEPOSITO SUPONE UNOS 20 MM. EN LA PARTE SUPERIOR DEL RECIPIENTE ESTA PREVISTA UNAENTRADA (11) PARA LA SUSPENSION DE CELULOSA Y EN EL EXTREMOS INFERIOR ESTA PREVISTO UNA SALIDA PARA LA SOLUCION HOMOGENEA DE CELULOSA.
