III.Rubber curing testerData processing requirements:
Figure 1 illustrates the drawing format, curves, and parameters.
ML: Low Torque
MH: High Torque
TS1 (Early Sulfurization Time, Curing Time): Time corresponding to an increase of 0.1 N·m torque from ML, calculated in minutes.
TS2 (Early Sulfurization Time, Curing Time): The time corresponding to the addition of 0.2Nm torque on the ML, calculated in minutes.
T10 (Initial Vulcanization Time): The time corresponding to the torque reaching 10% of (MH-ML), calculated in minutes.
T30 (Sulfur Time for Accurate Assessment): Time when torque reaches ML (MH-ML) × 30%, calculated in minutes.
T50 (Sulfurization Time for Accurate Assessment): The time, in minutes, when the torque reaches ML (MH-ML) x 50%.
T70 (Sulfurization Time for Accurate Assessment): Time when torque reaches ML (MH-ML) × 70%, calculated in minutes.
T90 (commonly used optimal vulcanization time): ML (MH-ML) × 90% - the time corresponding to the torque reaching this value, calculated in minutes.
VC (Vulcanization Rate Index): VC = 100 / (T90 - TS1)
