Comparative study of the low-temperature single step mixing and multi-stage process mixing

In this paper, we conduct a comparative experiment of the low-temperature single step mixing and multi-stage process mixing with low temperature single process mixing experiment platform. The experimental results show that the low-temperature single step mixing, compared with the traditional multi-stage process mixing, can save energy of about 13.3% and improve production efficiency of about 200%. The performance of final mixing has a significant increase in Mooney viscosity, the carbon black dispersion, and the physical and mechanical properties of the vulcanized rubber.
