Abstract

UN PROCESO PARA LA PREPARACION DE MICROCAPSULAS CON UNA MEMBRANA DE PARED HECHA DE UNA RESINA DE UREA DE POLIURETANO, QUE INCLUYE LAS FASES DE MEZCLAR UNA SOLUCION ACEITOSA Y UNA SOLUCION ACUOSA, PASAR LA SOLUCION MEZCLADA RESULTANTE A TRAVES DE UN ESPACIO ENTRE UN CILINDRO INTERIOR Y UN CILINDRO EXTERIOR QUE SE GIRAN UNO RELATIVO AL OTRO PARA FORMAR UNA EMULSION DE TIPO ACEITE EN AGUA Y DESPUES FORMAR UNA MEMBRANA DE PARED EN GOTAS DE LA EMULSION RESULTANTE. EN UNA REALIZACION PREFERENTE, EL ESPACIO ENTRE EL CILINDRO INTERIOR Y EL CILINDRO EXTERIOR TIENE PREFERENTEMENTE UN MARGEN DE 0.05 A 5 MM, MAS PREFERENTEMENTE DE 0.1 A 2 MM. EL TIEMPO DE RETENCION DE LA EMULSION EN LA PARTE DE LOS ESPACIOS TIENE UN ALCANCE DE 0.02 SEGUNDOS O MAS, PREFERENTEMENTE 0.2 SEGUNDOS O MAS. LOS CILINDROS EXTERNO E INTERNO FORMAN UNA COLUMNA, OPCIONALMENTE CON UNA PARTE CONICA.
