摘要: Hemolysate-filled hexamethylene sebacamide microcapsules (nylon-6, 10 membranes) were prepared by interfacial polymerization. Sheet lattice, frame turbine and marine impellers tested to control the microcapsule mean diameter size distribution parameters. Mean diameters ranging from 40 200 μm obtained depending on impeller type, rotational speed emulsifier concentration. The dispersion of preparations was best controlled with a lattice impeller, achieving standard deviation values less than 40% diameter. wire mesh dimensions had little effect parameters. Des de d'hexamethylene remplies d'hemolysat (membranes nylon 6.10) ont ete preparees par polymerisation interfaciale. On teste des treillis en feuilles, treilles encadre, turbines et helices marines pour controler le diametre moyen les parametres taille. Des diametres moyens compris entre obtenus fonction du type mobile. la vitesse rotation concentration d'emulsifiant. La taille etait mieux controlee avec un mobile valeurs d'ecart-type obtenues etant inferieures % moyen. Le fil maille avait peu d'effet sur distribution.
