Effects of Different Process Parameters on Rubber Mixing in Tandem Internal Mixer

摘要

This article is based on cooling water temperature, mixing time and rotor speed of downstream mixer to study effects of different process parameters on rubber mixing in tandem internal mixer. The experimental results show that the cooling water temperature has an important significance to improve the mixing quality, and the best cooling water temperature is about 30°C. Mixing time must be strictly controlled and the best range of mixing time is about 80 ～ 90s. Rotor speed has an significant effect on the physical properties of rubber, and the best rotor speed is about 30r/min. There is an optimal fill factor, and the best fill factor is 0.35.
