Настоящая статья посвящена исследованию стадий смешения каучука СКС-30 АРКМ-15 и технического углерода N234 в модельной резиновой смеси. В процессе смешения проводили изменение следующих показателей: крутящий момент, размах крутящего момента, температура резиновой смеси. С целью уменьшения шума полученные данные обработали путем расчета экспоненциально взвешенного скользящего среднего. В зависимости от продолжительности смешения проводили измерение показателей качества диспергирования на приборе Dispertester-3000 в соответствии с ISO 11345 и ASTM D2663; определяли на приборе RPA-2000 действительную, мнимые части комплексного модуля сдвига и работу, затраченную на разрушение сетки наполнителя. Стадии смешения, определенные различными методами, коррелируют между собой. Установлены характерные точки процесса смешения на зависимостях крутящего момента, температуры и размаха крутящего момента.
This article is dedicated to the study of the mixing stages of model mixture SBR-1706 with N234. The changes of torque, bandwidth and temperature of rubber composition in the process of mixing were measured. In order to reduce noise of data exponentially weighted moving average is processed. Depending on the length of the mixing cycle the quality of dispersion measured on the instrument Dispertester-3000 in accordance with ISO 11345 and ASTM D2663; on RPA-2000 the real, the imaginary parts of the complex shear modulus and work expended on the destruction of the mesh of filler were measured. Stage of mixing process measured by different methods were correlated. The characteristic points of mixing process on the curves of torque, temperature and bandwidth were described.
