AbstractThis study reports the research results on a mixing process using a stirred tank mixer under the action of a rotating magnetic field (RMF). Dimensionless correlations are proposed to predict the power consumption and mixing time for the mixing systems analysed. The results suggest that the mixing behaviour of the experimental set-ups tested may be assessed using the dimensionless mixing energy as the product of the power input and mixing time. In addition, an innovative strategy is proposed on the basis of the synergistic effect of the rotational Rushton turbine and the RMF generator. The values of the dimensionless energy thus obtained were used to compare the mixing process performed by the mixing devices tested. It is shown that the mixing process under the RMF action has significantly higher values of energy consumption than the conventional Rushton turbine. The total energy consumption for the mixing process performed by the RMF mixer may be reduced by concomitant use of a rotational agitator.

Recycling of polymers is an important environmental task. However, during the recycling of polymers many technological problems arise because usually not only one polymer, but also mixtures of polymers are recycled. To improve technological properties, such as increasing fluidity, improving processability and quality, reducing the melt pressure in the spinneret head, addressing surface defects caused by viscosity anomaly and excessive shear stresses, preventing the formation of deposits and residue on the forming tool, increasing productivity, reducing the amount gelic, etc., use processing and technological additives. In the research, the effect of technological additives manufactured by Weihai CY Dendrimer Technology Co., Ltd (China) on the technological and thermal properties of recycled polyolefins was studied. It was shown that the technological additives improved the technological properties of recycled polymers: the mixing energy decreased when receiving compositions, the melt flow index values increased, the thermal properties did not deteriorate. The results show the possibility of using of the technological additives in production to increase the productivity of processing equipment and reducing its energy consumption.
