Implementation of the Dрie Method in Technologies of Obtaining Structured Systems

Abstract

Within the framework of the work, experimental and laboratory studies of a complex of heat and mass transfer processes in multicomponent disperse systems that exhibit emergent properties have been carried out.
 The aim of the work is to determine the key factors that affect the properties of the final product, and bifurcation points for complex dispersed systems in terms of the mechanisms of structure formation.
 The authors determined the influence of key parameters such as the process temperature and shear stresses that arise in systems during processing in rotary-pulsating devices of the disk-cylindrical type.
 For systems with polyelectrolyte structures, the temperature ranges have been determined at which the intensity of the solvation process is maximum.
 The investigated multicomponent systems are sensitive to shear stress and the duration of its exposure. The limiting shear stresses are determined at which the destruction of structures begins and the system becomes fluid.
 Based on the results of the complex of works, a schematic diagram and a pilot plant for obtaining poly-component structured systems were proposed. Вatches of bactericidal sanitary-hygienic means and application medical-prophylactic means were obtained at the proposed installation and transferred for testing.

The Thermophysical Aspects of the Transformation of Porous Structures in Versatile Nanostructured Materials

“…Hydrodynamic processing, the purpose of which was to obtain a homogeneous suspension "HGMSA-H 2 O" with a maximum size of monolithic particles of 300 µm, was carried out in the recirculation mode at the experimental setup (Figure 1) [46]. The circulation loop for suspension comprises reactor R1 equipped with an anchor stirrer (AS), where initial system components are introduced.…”

“…During hydrodynamic DPIE treatment, the suspension is subjected to a multifactorial effect. Which of the complexes of factors will be dominant depends on the flow regimes determined by the rheological behavior of the suspensions and the concentration of the dispersed phase in the suspension [30,46,49].…”
