Introduction: 

Rubber rotor rheometer Measurement of vulcanization characteristics, 

requirements, ISO6502 requirements and Italian standards require T10, T30, T50, T60, T90 data.

Feature: 

1.the strong data function can support the drawing,storage

 and output printing of multiple curves under the same interface.

 2.it support the data query in many forms and output of excel queries and reports

 3.it has many analysis function like statics, deviation setting,standards curve

setting ,and CPK statistical calculation

 4.it has such function as interface query,local zoom and curve comparison.

 5.selection of any any vulcanization time,range selection and screen capture.

 6.analyzed the past test data once again,and increase or modify the reports,to

 avoid the loss of data.

 7.the test data are stored in the way of database,which is scientist

 the multiple data sequencing ways are convince for data retrieval and query.

 8.the machine will get the characteristic curve and data by measuring

 the strength of rubber.

 9.good reproducible and stasis tics.

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 .
