THE PHYSICO-CHEMICAL BASES OF THE TECHNOLOGY OF RECEIVING THE TRACK MEMBRANES FRON THE POLYVINYLIDENFLUORIDE AND ITS COPOLYMERS

The method of receiving the track membranes from the polyvinylidenfluoride and copolymers of vinylidenfluoride, including the radiation by heavy ions and a selective chemical etching of latent tracks of heavy ions by the alkali solutions of the kalium permanganate. The products of radiolysis, taking place under the action of the accelerated heavy ions, have been identified, its mechanism has been offered. The physico-chemical parameters of the selective etching of the latent tracks have been studied. Offered has been the optimum composition for the chemical etching of the tracks from the point of view of selectivity and speed. The registration properties of the polyvinylidenfluoride and copolymers of the vinylidenfluoride have been studied. The main properties and operational characteristics of the obtained chemically stable track membranes have been determined. The obtained specimens of the membranes are applied for cleaning of the agressive media and for separation of the micromixture of the proteins from the virus suspensions. The developed technology of manufacture of the chemically stable track membranes has been applied for manufacture of the experimental batches of membranes in the Laboratory of Nuclear Reactions of instituteAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
