Why do you need to tap and turn the rubber during the rubber mixing
process?
In the rubber mixing process, cutting the rubber material is very
important to the rubber mixing process.
To strengthen the rubber mixing effect, four conditions must be met
After the above analysis and discussion, it can be seen that in
order to complete the rubber mixing operation and obtain a better
rubber mixing effect, the following four points should be realized:
1. Make the friction angle of the rubber compound greater than the
contact angle (φ>α) in order to bring the rubber compound into
the roll distance;
2. Make the front and rear roller speeds (linear speeds) unequal,
so as to strongly squeeze and shear the rubber in the nip;
3. When mixing rubber, it is necessary to cut and turn the rubber
to destroy the closed return line of the rubber material and
strengthen the dispersion effect of the material;
4. During the rubber mixing process, the roller distance is
continuously adjusted to change the speed gradient and improve the
rubber mixing effect.
