説明

The characteristics of the mixing curve showing the relationship between the torque value and the mixing time obtained through the kneader mixing of SBR and calcium carbonate are investigated.<BR>For ten minutes after the beginning of the mixing, R= (R0-Rc) e-αt+Rc approximately holds, which is the same as the equation in which the change of time corresponds to consumed power in Banbury mixer.<BR>The torque value at the steady state is directly proportional to the viscosity as measured by the Flow Tester.<BR>The time when the mixing of rubber and filler will be completed can be predicted from the variation of deflection range of torque value (deflection of recorder pen), and it is proved that the deflection after completed mixing of both rubber and filler entirely depends upon the elasticity of material at given temperature and given composition.
