METHOD AND DEVICE FOR EVALUATING PROCESSABILITY OF VISCOELASTIC MATERIAL, METHOD FOR SETTING CONDITION FOR PROCESSING VISCOELASTIC MATERIAL, AND DEVICE FOR PROCESSING VISCOELASTIC MATERIAL; AND METHOD FOR CONTROLLING PROCESSING OPERATION OF VISCOELASTIC MATERIAL |
摘要 |
A method and a device evaluate a processability of a viscoelastic material. A measuring step and means measure a complex viscosity modulus eta* and two complex elasticity moduli G*1, G*2 in respective two shear ranges with different shear speeds, by the following: varying a vibration frequency and a vibration amplitude at a given temperature range, and controlling a shear stress applied to the viscoelastic material which is mixed under a given mixing condition. The shear stress causes a reactive stress. The complex viscosity modulus eta* and the two complex elasticity moduli G*1, G*2 are measured based on the reactive stress. A first operation operates an apparent activation energy Ea by the following:whereT is temperature,R is gas constant,eta* is complex viscosity modulus.A second operation operates a complex elasticity modulus change ratio G*r, a ratio between the two complex elasticity moduli G*1, G*2.
