Rubber Rheometer/Rotorless Rheometer

HY3310 Rubber Rotorless Rheometer is used to determine the vulcanization characteristics of a rubber compound. It can dynamically display temperature curve and curve of shear modulus- vulcanization time under set temperature and pressure. It consists of main machine, temperature determination and control system, sensor, computer, data collector, printer and electrical components.

1.     It is a necessary equipment to optimize formula, make production parameters and improve quality of rubber product

2.     High accuracy, good repeatability and stability, convenient and practical, it can precisely find out the best vulcanizing time

3.     Imported intelligent digital meter, easy to adjust and set, large temperature control range, high accuracy

4.     Computer control, collect, save and save test data, printout test result

5.     Test curves can be magnified and compared

6.     Windows operation platform to make date processing more accurate. 

Testing Result:

M_L : Min. torque (dNm)—The testing value of sample’s vulcanization characteristics (viscosity) before vulcanization.
M_H : Max. torque (dNm)—The testing value of sample’s shearing modulus or rigidity. Including even torque, max. torque for returning curve, and the max. torque during the specific period of no even or returning curve happens.
Ts₁ (min)—The time when the torque increases to M_L +1dNm, the angle of oscillation is 0.5° or 1°. This figure shows the scorch time.
Ts₂ (min)—The relative time when the torque increases to M_L +2dNm, the angle of oscillation is 3°. This figure shows the scorch time.
T₁₀ (min)—The time when the torque increases to M_L + 10 (M_H - M_L ) / 100dNm. This figure shows the scorch time.
T₃₀ (min)—The time when the torque increases to M_L + 30 (M_H - M_L ) / 100dNm.

T₆₀ (min)—The time when the torque increases to M_L + 60 (M_H - M_L) / 100dNm.
T₉₀ (min)—The time when the torque increases to M_L +90 (M_H - M_L) / 100dNm. This figure shows the optimum cure time.
Ti (min)—The time when the torque increases to M_L + i (M_H - M_L ) / 100dNm.
Vc—Vulcanizing speed index. Vc =100/(T₉₀ – Tsi)
