Preparation of monodispersed calcium alginate gel beads in high voltage electrostatic field
In this paper, the effect of operation parameters on t he monodispersity of calcium-alginate gel beads prepared in high-voltage electro static field were analyzed.The parameters included the applied potential (U) ,the distribution of electrostatic field, the frequency and the flow rate of so lution through the capillary. Furthermore, the process is analyzed with the the ory of jet break-up in electrostatic field. The result showed that the modifie d symmetrical electrostatic field was more advantageous in preparing the monodis persed gel beads than the traditional method. Meanwhile,gel beads with good mono dispersity(CV20%) and stability without aggregation were produced under a r ange of applied potential (U), frequency and flow rate of solution through t he capillary.
