Abstract

SE DESCRIBE UN PROCESO PARA LA PREPARACION CONTINUA DE UNA EMULSION DE FASE ALTAMENTE INTERNA APROPIADA PARA LA SIGUIENTE POLIMERIZACION DENTRO DE LOS MATERIALES DE ESPUMA POLIMERICOS QUE, TRAS DESHIDRATARLOS, ACTUAN COMO ABSORBENTES PARA FLUIDOS CORPORALES. EL PROCESO COMPRENDE LA INTRODUCCION CONTINUA DE CIERTO TIPO DE FASE DE ACEITE MONOMERO-CONTENEDORA Y CIERTO TIPO DE FASE DE AGUA ELECTROLITA-CONTENEDORA DENTRO DE UNA ZONA DE MEZCLA DINAMICA DE POCA AGUA PARA LOS CONTENIDOS DE FASE DE ACEITE. LOS INDICES DE FLUJO SE AJUSTAN CONSTANTEMENTE PARA INCREMENTAR EL AGUA PARA LOS CONTENIDOS DE ACEITE DE LAS FUENTES DE SUMINISTRO DE LA ZONA DE MEZCLA MIENTRAS LOS CONTENIDOS DE LA ZONA SE SUJETAN A UNA AGITACION DE CIZALLA SUFICIENTE PARA FORMAR UNA EMULSION DE FASE INTERNA ALTA, EN LA SIGUIENTE POLIMERIZACION, OFRECIENDO UNA ESPUMA QUE TIENE UN PROMEDIO DE TAMAÑO CELULAR DE 5 100 MICRONES. LA FORMACION DE TAL EMULSION SE COMPLETA AL SUMINISTRAR LOS CONTENIDOS DE LA ZONA DE MEZCLA DINAMICA A Y ATRAVES DE UNA ZONA DE MEZCLA ESTATICA.
