LR-A019 Rubber Mooney Viscometer

Character:

Mooney Viscometer is used for measuring viscosity and relaxation of base rubber, raw rubber stock or rubber mass prevulcanization properties, it is also used for measuring viscosity in Mooney value for compounded or uncompounded unvulcanized natural, synthetic or regenerated rubber.

This instrument has excellent performances including automatic calibration, higher stability. It can perform the following tests: viscosity, scorch and stress relaxation.

Test standard:

Accord with GB/T1232″Rubber unvulcanized -Determination of mooney viscosity”,GB/T 1233 ”Rubber,unvulcanized-Determination of prevulcanization characteristics-Shearing disk method”,ISO289,ISO667ect.

LR-A019 Rubber Mooney Viscometer

Specification:

Test Results

Measure of Mooney viscosity (Large rotor):

MI — initial Mooney viscosity.

ML – The minimum Mooney value in the last 30 seconds before the motor stopped.

Mx-t – Mooney value relating to time t.

x-the time of preheat, t-Mooney test time

Stress Relaxation

MRe – Mooney value at the end of stress relaxation.

TRx – time needed for x% torque stress relaxation.

Xy% – % of Viscosity decay after motor stopped y sec.

The value of exponent a, the constant k, the correlation coefficient r, and the area A .
