Рассмотрены способы непосредственной и косвенной оценки качества смешивания дисперсных твердофазных компонентов в жидком полимерном связующем. Показано, что ряд получивших развитие в других областях технологии материалов способов количественной оценки смешивания (связанных с экстракцией твердофазных компонентов), не пригоден для контроля энергонасыщенного гетерогенного композиционного материала (ЭГКМ). Экспериментальным способом выявлены критериальные значения (диапазон) плотности ЭГКМ и определены основные группы характеристик ЭГКМ, обеспечивающих приемлемые эксплуатационные свойства данного материала. С использованием современного оборудования по апробированным методикам проведен комплекс исследований по установлению степени равномерности распределения в ЭГКМ частиц твердофазных компонентов, наличия, формы, размеров и распределения в объеме дефектов структуры материала, физико-механических свойств ЭГКМ после полимеризации. На основе сопоставления результатов инструментального определения основных характеристик ЭГКМ (структурных, физических) с эксплуатационными свойствами материала в зависимости от длительности процесса смешивания на конкретном оборудовании при прочих равных условиях установлено, что для успешного решения технологических задач приемлемым является способ косвенной оценки качества смешивания по итогам определения плотности ЭГКМ после его полимеризации. Этим может быть обеспечен оперативный выходной контроль качества конечного продукта, не требующий значительных материальных и временных затрат, при разработке технологических процессов и в ходе производства ЭГКМ.

Methods of direct and indirect assessment of the quality of mixing dispersed solid-phase components in a liquid polymer binder are considered. It is shown that a number of methods for the quantitative estimation of mixing (associated with the extraction of solid-phase components), which have been developed in other areas of the technology of materials, are not suitable for controlling an energy-saturated heterogeneous composite material (EHCM). An experimental method revealed the criteria values (a range) of the EHCM density and determined the main groups of the EHCM characteristics, ensuring their acceptable operational properties. By means of modern research equipment using proven methods, a series of studies was carried out to establish the uniformity of the distribution of particles of solid-phase components in the EHCM, the presence, the shape, sizes and distribution in the volume of defects in the structure of the material, the physicomechanical properties of the EHCM after polymerization. According to a comparison of the results of instrumental determination of the main characteristics of the EHCM (structural, physical) with the operational properties of the material, depending on the duration of the mixing process on a specific equipment under otherwise equal conditions, it was found that for the successful solution of technological tasks it is acceptable to assess indirectly the quality of mixing according to the results of density determination of the EHCM after its polymerization. This can provide operational output quality control of the final product that does not require significant material and time costs during the development of technological processes and during the production of the EHCM.
