Research of the viscosity of unfilled polymers using quality functionals

Abstract

Kinetic processes of unfilled polymers structure formation are explored and mathematical method of polymer composites modelling using kinetic (transient) processes quality functionals is proposed. Advisability of kinetic (transient) processes consideration as necessary and sufficient sign of thermosetting binder structure formation is justified. The processes occurring during the formation of the modified polymer and appearance of qualitatively new properties while maintaining chemical individuality of each component are considered. Approbation of mathematical method is carried out in the construction of mathematical model and study of unfilled epoxy resin ED-16 viscosity.

Optimization of granulometric composition of railway routes ballast layer

“…For example, to obtain materials that are resistant to highly aggressive environments or under the action of ionizing radiation, it is necessary to take into account the resistance of the composite components to the action of an aggressive environment. Also, the filler of the ballast material, and the design of the upper part of the embankment, and the joints that are formed at the interface between the phases of various materials and structures during their interaction should also have resistance [6].…”

“…Calculations of the coefficients of the regression equation ( 1), the prediction dispersion function and the verification of the adequacy of the equation were performed according to the standard method [6].…”
