XDR®: Moving Die Rheometer (MDR) / Rotorless Oscillating Shear Rheometer
The XDR® CureMeter System XDR® CureMeter Systems by CCSi
CCSi's development of the uniquely heated rotor with temperature control in the XDR® Oscillating Disk Rheometer (ODR) was followed by a vision of a hybrid ODR with the performance of a conventional Moving Die Rheometer (MDR).
The XDR®, configured as a Moving Die Rheometer or Rotorless Oscillating Shear Rheometer (U.S. Patent 5,526,693 ... other patents pending), consists of a heated third member with an elastomeric seal between the bottom of the rotor and the bottom of the lower die cavity.
The seal extends from the edge of the rotor to the inside wall of the die. This prevents the sample from flowing under the rotor, and contains it in the upper die cavity.
The contribution of the seal to torque is small and readily corrected. Thus, the heated third member actually becomes a moving heated die, i.e., a “Virtual” Moving Die Rheometer.
The thin sample rapidly achieves testing temperatures, the sample is easily removed from the test chamber, and the simplicity of the design provides for easy maintenance.
It should be noted that a strain transducer is a key component in the design of this cure meter. It provides a continuous measurement of the strain imposed on the test sample.
This measurement allows the determination of the mechanical properties of the test sample as well as correcting for any unavoidable deflections in the system. The application of this feature are key to overcoming some of the performance limitations of existing cure meters. These facets are discussed in detail in the article “Innovations”.
Cross Sectional View of the Moving Die “ ... in the Moving Die Rheometer configuration the sample is sealed between the upper die cavity and an elastomeric seal ... allowing the uniquely heated third member to become a virtual moving die.”
