Science and Innovation| Summary: | Introduction. The current state of filtering technology has been defined by the growing requirements for the purity of technical fluids, the enhanced durability of filter elements, and the advances of modern nanotechnology, particularly with respect to magnetic properties.Problem Statement. The incorporation of nanomagnetic components based on iron oxides has had the potentialto fundamentally transform the structure and functional parameters of porous materials used in filter devices. However, no technology has yet enabled the adjustment of these parameters under the influence of a magneticfield.Materials and Methods. The materials employed are porous structures based on polyurethane foams saturated with nanocomposites of divalent and trivalent iron oxides. Experimental methods have included measurements of magnetic induction and the throughput capacity of porous elements, while theoretical methods have involved the analysis of magnetic forces and the application of hydrodynamic equations for channel flows.Results. Porous filter materials infused with magnetic nanocomponents consisting of mixed divalent and trivalent ferric oxides have demonstrated structural changes under the influence of a magnetic field. The proposed system of electromagnetic control for filters filled with magnetic nanocomposites has allowed the adjustment of their structural parameters. When the magnetic field induction has been varied from 0 to 0.2×10–³ T, the filter bandwidth increases 1.7—1.9 times, corresponding to a change in the average pore diameter by a factor of 1.24—1.17. This principle has enabled both the increase of filter throughput as clogging occurs and the adjustment of pore sizes to selectively retain harmful components of predetermined dimensions.Conclusions. The study has confirmed the feasibility of regulating the structural parameters of porous filteringmaterials by incorporating magnetic nanocomponents. Electromagnetic control has made it possible to achieveadjustable filter capacity tailored to specifi c operational requirements. |
