3. Using the latest principles of a "host + computer + printer" structure Feature of Control Software: 1. Unit of options: kgf-cm, lbf-in Nm, the dN-m, the MV; 2. Test data: contains the Mooney viscosity, scorch various data; 3. Test curve: Mooney viscosity curve, Mooney scorch curve, temperature curve of the upper and lower moldThe Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. As defined by international standards, the sample material is preheated for a defined period in a closed die cavity, then sheared by the embedded rotor at a constant rate. It is interesting that the Mooney viscosity for one of the `bad' lots was very close to the Mooney viscosity for the `good' lot (ML1+4 of 93 vs 94). Table 11 gives a description of these three lots. Fig. 31 shows very good separation of the `good' vs the `bad' lots of natural rubber when comparing the uncured tan δ at high strain test conditions. Abstract The direct near‐infrared spectroscopic reflectance measurements of prevulcanized natural rubber (brown crepe) was employed for determination of its Mooney viscosity. NIR reflectance spectra were obtained for a total of 100 samples whose Mooney viscosity (VM in the range 68–95 units) have been determined by the standard reference .
Traditional data-driven empirical models for online prediction of the Mooney viscosity have not utilized the information hidden in lots of unlabeled data (e.g., process input variables during each mixing batch). A simple semi-supervised nonlinear soft sensor method for the Mooney viscosity prediction is developed.
To that end, we investigated Mooney torque relaxation. The Mooney viscometer is an inexpensive instrument (cost and maintenance) that is easy to use and, above all, available in the great majority of factories producing natural rubber. The measurement of NR Mooney viscosity is governed by international standard ISO 289.Multiple Mooney Viscosity tests performed on Mooney Viscometer. 3 TORQUE & TEMPERATURE Torque Calibration Torque is the most critical point of measurement in Mooney Viscometers. Torque calibration is performed . When receiving on-site ISO/IEC 17025 calibration services, it is important to know what to expect.

However, if the Mooney viscosity is too low, the physical and mechanical properties of vulcanized products are poor. From the Fig. 4, we can see that with the extension of storage time, the Mooney viscosity of NR shows an increasing trend. The Mooney viscosity of NR goes from 76 to 83 with storage time from 0 to 48 h with a rate increase of 9.21%.

The Mooney viscosity of grade TSR 10 samples, although initially higher at about 60 Mooney units, reduced much more rapidly and continuously throughout to less than 25 Mooney units after prolonged mastication for 13 min. Samples of grade TSR3CV meanwhile decreased slightly and seemed to attain a minima after just out 4 min of mastication.The Mooney viscosity of the sample set was measured by the standard method and the values were in the range 65–95 units. The samples were divided in two subsets, one for calibration, containing 70 samples, and the other for external validation, containing the remaining 30 samples. The Mooney viscosity average values and their standard .
