MODELING OF THE ULTRAFILTRATION OF ELECTROPHORETIC EMULSION PAINT

Attempts of modelling mathematically the ultrafiltration process of so luble emulsion paints have been presented. Analyses were carried out b ased on data of ultrafiltration experiments performed with tubular pol yacrylonitrile and poly(vinyl chloride) membranes at a paint concentra tion of 10 %. The constants of the general dimensional mass transfer c orrelation, as well as the general dependence of the volume permeate f lux on ultrafiltration process parameters (i.e., transmembrane pressur e and cross-flow velocity), have been determined.
