Abstract

ESTA INVENCION ES UN METODO PARA CONVERTIR PARTICULAS PEQUEÑAS DE POLIMEROS SUPERABSORBENTES EN PARTICULAS MAYORES. LA INVENCION ESTA DIRIGIDA PRINCIPALMENTE A PROCESOS DE SOLUCION ACUOSA PARA PREPARAR POLIMEROS SUPERABSORBENTES. EN ESTOS METODOS DE POLIMERIZACION DE SOLUCION ACUOSA, EL PRODUCTO DE LA REACCION DE POLIMERIZACION ES UN GEL DE VISCOSIDAD ALTA QUE SE SECA Y SE MUELE EN PARTICULAS. EN ESTE PASO DE MOLTURACION, UNA PARTE DEL PRODUCTO SE PRODUCE COMO PARTICULAS MENUDAS NO DESEADAS QUE TIENEN ABSORBENCIA POBRE Y POBRES PROPIEDADES DE FABRICACION; I. E. ELLOS "BLOQUEAN EL GEL" Y ELIMINAN EL POLVO. SEGUN LA INVENCION, LAS PARTICULAS MENUDAS DE POLIMERO SUPERABSORBENTE (HASTA 3 PARTES APROXIMADAMENTE) SE MEZCLAN CON EL GEL DE GRAN VISCOSIDAD PRODUCTO DE LA REACCION (100 PARTES) QUE CONTIENE APROXIMADAMENTE 20 PARTES EN PESO DE POLIMERO SUPERABSORBENTE Y AGUA (5 PARTES POR CADA PARTE DE PARTICULAS RECICLADAS) PARA FORMAR UNA MEZCLA CON PROPIEDADES REOLOGICAS MEJORADAS. LA MEZCLA RESULTANTE PUEDE PROCESARSE EN PROPORCION MAYOR QUE EL GEL PRODUCTO DE LA REACCION DE IGUAL CONTENIDO EN SOLIDOS LO QUE DA COMO RESULTADO UN RENDIMIENTO MAYOR DEL PRODUCTO Y UNA PRODUCTIVIDAD AUMENTADA.
