MooneyCheck - Drive

Mooney Viscometer controlled by Personal Computer for the performance of Viscosity, Scorch and Stress Relaxation tests.

The MooneyCheck - Drive is a Mooney Viscometer, which permits to measure the Mooney viscosity, Pre-curing (scorch) and Stress Relaxation Characteristics of uncompounded or compounded rubbers In conformity with ISO 289-1, ISO 289-2, ISO 289-3, ASTM D 1646 Standards.
The test is carried out by measuring the torque, which has to be applied under specified temperature and pressure conditions, in order to rotate a metal disc at 2rpm speed in the cylindrical test chamber filled with rubber.
The resistance offered by the rubber to this rotation is expressed as the Mooney viscosity of the test piece.

The new 'Drive' generation 
The new generation of 'Drive' instruments is the result of 40 years of experience in the measurement of rheology of rubber and incorporates the most modern technologies regarding mechanical construction, measurement sensors and control software.

MooneyCheck_10 software 
The MooneyCheck_10 program connects to the Gibitre SQL database to store test Results and Curves within the Datagest data management program.
The program allows you to:
• Quickly identify the sequence of tests to be performed
• Automatically adjust the instrument according to the required test conditions
• Produce the test Curves (Viscosity, Scorch, Stress Relaxation, Temperature)
• Compare the results with the tolerance limits
• Elaborate statistical analysis (Carta-X, Gaussiana, Media, Dev St., Max, Min, Cp, Cpk)
• Produce customized reports

Calculated Results 
The software allows you to prepare customized test procedures that include all the calculations required by the standards and product specifications. The dedicated page describes all the available calculations.
Option: Variable Rotor Rotation Speed 
Optional configuration of the MooneyCheck-Drive instrument for managing the rotor speed during the test.
• The configuration allows to define the Rotation Speed as a configurable parameter of the Test Procedure.
• The speed can be set between 0.01 and 20 RPM.
• The execution of tests at different speeds allow to evaluate the behavior of your product according to the shear rate and to simulate the behavior of the product in the conditions of use.
Instrument control Panel 
The instrument is equipped with a large touch-screen display with dimensions 10.2“. The buttons on the display permit to start and stop the tests. The display provides complete information about the status of the instrument: connection to the software, temperature of the dies, diagnostic of the sensors installed.
Rotor Pneumatic Ejection 
All Mooney Viscometers produced by Gibitre have a pneumatic ejection device for the rotor which simplifies the cleaning and replacement of the specimen between subsequent tests.
Light panel 
A light panel, installed in the front part of the instrument, changes the color and permits to check the status of the instrument from a distance. The indicator light identifies the following statuses: Instrument ready, instrument under test, instrument setting test temperature.
Automatic Torque Calibration 
The Calibration weight integrated with the instrument permits the automatic Calibration of the torque sensor.
The Calibration is easily performed by pressing the Calibration button on the Control Display, which activates the pneumatic lifting of the weight.

Standard Calibration service for Mooney Viscometer 
The calibration is performed with reference to the requirements of ISO 289-1 standard.
The service includes:
• Ordinary maintenance of the instrument
• Replacement of the sealing of the lower die.
• Calibration of the temperature of upper and lower dies of instrument (at 100°C and 125°C).
• Calibration of the time for temperature recovery at test start
• Calibration of the torque reading (at 100 Mooney points)
• Calibration of the rotation speed of the rotor
• Final check with Standard Gibitre Compound
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.

Sample Calibration Report

Certified Rubber Samples For Mooney Test 
Pair of certified butyl rubber specimens (Isobutylene - Isoprene) for the verification of Mooney Viscosity.

The specimens are obtained, without rework, from a bale coded as IRM (Industry Reference Material) prepared by the working group ASTM D11.20 (task Group subcommittee on Compounding Materials and Procedures) in accordance with ASTM D 4678.
Datagest program 
The Datagest program is the database management tool always installed in combination with all Gibitre instrument-control programs.
The program permits to:
• Select, filter, print, export and analyse the test results stored with all the instruments connected.
• Prepare test procedures by defining the test conditions and the results to be produced
• Set tolerance limits for each product by manual insertion or using the statistical analysis (mean and standard deviation) of saved results
• Prepare multi-instrument test reports

Gibitre Standard SQL Database 
All the Gibitre programs use a database with SQL structure for saving the results.
The database can be installed inside an SQL instance present on the company server or it can be installed on a PC connected to a measuring instrument. The installation of the Microsoft SQL service (Express version) is included in the delivery.

Industry 4.0 integration 
The instrument and the software have been specifically developed to optimize integration with other environments.
The database in SQL format and the Gibitre_Company_Connect program allows you synchronize your company management software with Gibitre database and to speed up the identification of the tests and to use bar-code readers or similar devices.
The automatic logging service permits to send alarm information to the cloud-service platform of Gibitre Instruments in order to optimize the reaction times of the Service Support.

Preparation of Test Reports 
Version 10 programs make the following options available for preparing test reports:
• Selection of printing language
• Company logo insertion
• Print a single test / a Group of tests
• Print of Test Curves
• Print Numerical Results
• Print the Limits of Tolerance
• Print Statistical Results
• Print Legend with explanation of results
