Аннотация
Experiments to determine the maximum size of through pores in MFAS-type membranes (Vladipor Company) were carried out in two ways: by the “bubble-point” method according to GOST (State Standard) 50516-93 and the “crystallization-onset” method. The experimental values of the pressure difference upon the appearance of bubbles in a liquid and the temperature of the crystallization onset were obtained for membranes of different brands. It was shown that the membrane thickness influences these parameters. Repeated measurements of the maximum size of through pores were performed and showed good reproducibility of the experimental data.
