Mixing temperature of small internal mixers

A high mixing temperature is conducive to the plastic flow and deformation of raw rubber and rubber materials, which is beneficial for the wetting of the surface of solid compounding particles and the mixing and powder absorption of rubber. However, it also reduces the viscosity of the rubber material, which is not conducive to the crushing and dispersion of compounding particles. Excessive mixing temperature can accelerate the thermal oxidative aging of rubber, leading to a decrease in the physical and mechanical properties of vulcanized rubber, resulting in the phenomenon of over mixing; It can also cause scorching of the rubber material, so effective cooling measures must be taken during the mixing process of the internal mixer; But the temperature should not be too low, otherwise there will be a phenomenon of adhesive dispersion.
Mixing time of the internal mixer
The mixing time required for mixing rubber materials using an internal mixer under the same conditions is much shorter than that of an open mixer. When the mixing quality requirement is constant, the required mixing time decreases with the increase of the speed of the mixer and the pressure of the top bolt. Improper feeding sequence and improper mixing operation can prolong the mixing time.
