Rheocheck Profile OD - PC
Oscillating Disk Rheometers controlled by Personal Computer.
Overview
Gibitre OD Rheometer measures the cure characteristics of a rubber compound in conformity with the international standards.
The measure of the vulcanization is carried our by measuring the change in the mechanical characteristics of the sample. The instrument permits to apply a cyclic strain to a test piece and to measure the associated force.
The test is carried out at a constant temperature and the measure of stiffness recorded continuously as a function of time.
Instrument Characteristics
Easily accessible test chamber with transparent safety panel and safety lock.
Test chamber in compliance with international standards.
Direct test chamber heating controlled by thermoregulators with PID microprocessor with O.1 °C accuracy.
Control system for compressed air pressure, cleaning and lubrication.
Pneumatic Rotor ejection and clam- ping systems.
Easy-to-change rotor oscillation amplitude.
Designed for eventual application of a fume aspiration system.
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.
RheoCheck_10 Software
The RheoCheck_10 program connects to the Gibitre SQL database and allows you to collect all the results 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
• Analyze the Test curves (S', S", S* Tang_Delta, Der(S'), Temperatures of the dies)
• Compare the results with the tolerance limits
• Elaborate statistical analysis (Carta-X, Gaussiana, Media, Dev St., Max, Min, Cp, Cpk)
• Produce customized reports
Datagest program: total Traceability
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
Standard Calibration service for Oscillating Disk Rheometer.
The calibration is performed with reference to the requirements of ISO 6502-2 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the temperature of the dies at 3 temperatures (177°C, 190°C).
• Calibration of the time for temperature recovery at test start at 180°C (NEW)
• Calibration of the Torque (at 50 dN*m)
• Calibration of the torque standard supplied with the instrument.
• Final check with Standard Gibitre Compound (NEW)
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.
Accessories
Volumetric die cutter.
Dies for OD rheometer with two Ø 8mm moulds.
Pressure sensor integrated in the upper die with 0.1 bar resolution.
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.
