Comparison of Rotational Viscometer and Capillary Rheometer in Testing the Flowability of Resin Processing
The rotational viscometer measures torque via rotor rotation, making it suitable for testing the static or low-shear fluidity of resins under low shear rates, with simple and quick operation. The capillary rheometer, on the other hand, forces samples through a capillary to simulate high-shear processing, providing flow data closer to actual production conditions, but it is more complex and time-consuming to operate.

Key Points for Measuring the Viscosity of Resin Solution with a Rotational Viscometer
When measuring the viscosity of resin solution with a rotational viscometer, it is based on the principle of internal friction, and the viscosity is calculated from the torque generated by the rotation of the rotor.
The main issue with using a Ubbelohde viscometer is that 90% of capillary blockages are caused by inadequate sample filtration.
More than 90% of capillary blockage in Ubbelohde viscometers during measurement is due to inadequate sample filtration. Minute particles or gels in the sample tend to adhere to or become trapped when flowing through the narrow capillary, leading to abnormal flow rates and affecting measurement accuracy.
