Abstract

PROCESO DE PREPARACION DE DISPERSIONES ACUOSAS DE PARTICULAS DE POLIMERO MAGNETIZABLE DE DISTRIBUCION ESTRECHA A PARTIR DE DISPERSIONES ACUOSAS DE DISTRIBUCION ANCHA CARACTERIZADO EN QUE: A) SE AÑADE LA CANTIDAD DE AGUA DE LA DISPERSION ACUOSA DE DISTRIBUCION ANCHA DE MANERA QUE EL CONTENIDO PONDERAL DE PARTICULAS DE POLIMERO MAGNETIZABLE ESTE COMPRENDIDO ENTRE APROXIMADAMENTE 1 Y 40% DE DICHA DISPERSION; B) SE AUMENTA LA CONCENTRACION DE AGENTE TENSIOACTIVO DE LA DISPERSION OBTENIDA EN LA ETAPA A) HASTA OBTENER DOS FASES, UNA FASE LLAMADA LIQUIDA Y UNA FASE LLAMADA SOLIDA; C) SE SEPARAN LAS DOS FASES; D) SE REINICIAN EVENTUALMENTE LAS ETAPAS A), B) Y C) SOBRE LA FASE SOLIDA TANTAS VECES COMO SEA NECESARIO; E) SE RECUPERA LA DISPERSION ACUOSA DE DISTRIBUCION ESTRECHA.
