Product Description

　　Equipment Overview

　　The interfacial shear high-temperature viscometer is an instrument primarily designed to characterize and quantitatively measure the shear rheological properties of gas–liquid and liquid–liquid interfaces. Compared with conventional rheometers, it enables the detection of phenomena occurring within a thickness of just a few nanometers. This instrument can comprehensively determine the shear rheological parameters of thin films, including interfacial viscosity, elastic modulus, viscous modulus, compliance, and relaxation time.

　　Key Performance Indicators

　　● Air-bearing design with a built-in normal-force sensor; the rotor is mounted using a threadless double-cone connector.

　　All measurement rotors and temperature control units feature intelligent automatic identification.

　　● Minimum torque in rotation mode: 1 nNm; minimum torque in oscillation mode: 0.5 nNm; maximum torque: 200 mNm.

　　● Maximum angular velocity: 314 rad/s; minimum angular velocity: 10⁻⁸ rad/s.

　　● Frequency range: 10⁻⁷ to 628 rad/s;

　　● Speed response time: 5 ms; strain response time: 15 ms;

　　● The high-temperature visualization module employs Peltier-based temperature control, with a temperature range of -20 to 200°C.

　　● Temperature control method for the high-temperature microscopic visualization module: bottom plate plus top cover.

　　● Objective magnification of the high-temperature visualization test module (excluding electronic magnification): 20×, with optical compensation; the fixture is a 42 mm quartz flat plate.

　　● The interfacial shear module employs Peltier semiconductor temperature control, offering both interfacial shear and interfacial oscillation measurement modes, with a temperature control range of 5–70°C.

　　● Conventional polymer rheology testing module, supporting all standard test modes including steady shear, dynamic oscillation, creep‑recovery, stress relaxation, and temperature sweeps, with built-in fitting and analysis capabilities for common rheological models. Features a DC‑synchronous motor design (not a drag‑cup motor), Peltier‑based temperature control, and a dual‑plate plus upper‑cover heating/cooling configuration, with a temperature range of –40 to 200°C.

　　● Equipped with a high-temperature visual rheological testing module, it enables steady-state shear, dynamic oscillation, creep‑recovery, stress relaxation, and temperature sweep measurements at elevated temperatures. It also provides real-time visualization of the sample‑testing process, allowing for live monitoring of rheological tests with simultaneous photo and video recording; data are linked to corresponding images for direct comparison.

　　● The high-temperature visualization test module features seamless switching between conventional illumination and polarized light.

　　●The interface testing module shall be equipped with a double-cone measurement fixture and capable of automatically detecting the interface.

　　● Expandable high-temperature, high-pressure rheology measurement module, with a maximum temperature of 300°C and a maximum pressure of 100 MPa; expandable small-angle laser light scattering rheology measurement module; expandable powder flow cell and powder shear sample cell modes for powder rheology measurements. The powder flow cell can be used to determine the flow properties of compacted powders, and with additional accessories, temperature and humidity can be fully controlled.

　　● Features an air-bearing design, incorporates a built-in normal-force sensor, and employs a threadless double-cone connector for rotor mounting.

　　● Minimum torque in rotation mode: 1 nNm; minimum torque in oscillation mode: 0.5 nNm; maximum torque: 200 mNm.

　　● Maximum angular velocity: 314 rad/s, minimum angular velocity: 10⁻⁸ rad/s;

　　● Speed response time: 5 ms; strain response time: 15 ms;

　　● Conventional polymer rheology testing module: Peltier‑controlled coaxial cylinder temperature range: −30 to 200°C;

　　● Peltier temperature-control principle for the high-temperature visualization module; minimum temperature: −20°C, maximum temperature: up to 200°C;
