Solution liquid rotational rheometer

1、 Product Introduction

Solution liquid rotational rheometerIt is one of the instruments used to study and measure the rheological properties of materials. It applies forced steady-state rate load, steady-state stress load, dynamic sine periodic strain load, or dynamic sine periodic stress load to the sample to observe the response data of the sample to the applied load; By measuring rheological data such as shear rate, shear stress, oscillation frequency, and stress-strain amplitude, it is a widely used rheological measuring instrument in the field of materials, which can study the flow and deformation characteristics of samples from low viscosity fluids to high-strength solids.

IISolution liquid rotational rheometerworking principle

The servo motor drives the concentric outer cylinder, and the rotation of the outer cylinder drives the rotation of the internal sample. The sample generates shear stress on the measuring hammer, and the shear stress is measured to calculate the viscosity, elastic modulus, energy dissipation modulus, phase angle and other parameters of the sample.

3、 Product Features

1The contact part of the sample is made of Hastelloy alloy material, which can measure common corrosive samples.

2The measuring hammer is a frictionless suspension structure, and the measurement data is not affected by friction, with high accuracy.

3Design anti climbing rod devices to reduce the impact of liquid climbing rods on sample viscosity.

4The stress plate and measuring hammer are integrated structures, effectively avoiding the problem of inaccurate measurement of low viscosity samples.

5The entire testing process is carried out under high temperature and pressure, and pressure has no effect on the measurement results.

6Flexible testing process, facilitating the modification of testing steps during the testing process. The same sample can be freely switched between steady-state testing and oscillation mode.

7Laser displacement sensors have a high sampling frequency and there is no possibility of data lossThe test data is stable.
