Rheological measurement equipment for materials and using method thereof

Abstract

The invention belongs to the research field of liquid-state and semi-solid state materials rheological features and provides rheological measurement equipment for materials and a using method thereof. In the prior art, when the rheological features of materials are measured, a spring scale is manually pulled upwards for loading, and loading intensity, loading temperature and displacement collecting stability is quite poor. The rheological measurement equipment comprises a temperature-control oil bath device, a weight automatic loading device, a balance device, a displacement measurement device, a sample holder lifting device, a slice clamp, a slice, a sample box, a machine frame and a protective cover, wherein the temperature-control oil bath device, the sample holder lifting device, the balance device, the weight automatic loading device and the protective cover are installed on the machine frame, the displacement measurement device and the sample box are installed on the sample holder lifting device, the slice clamp is connected to the balance device, and the slice is installed on the slice clamp. By the adoption of the rheological measurement equipment, during measurement, loading intensity, loading temperature and displacement collecting are kept well stable.

Description

technical field [0001] The invention belongs to the research field of rheological characteristics of liquid and semi-solid materials, and is especially suitable for measuring the rheological characteristics of liquid and semi-solid materials under given temperature and stress. Background technique [0002] A rheometer is an instrument used to measure the rheological properties of a substance. The rheological property is that a certain substance exhibits dual characteristics of elasticity and viscosity to external forces, that is, viscoelasticity. Among them, viscosity corresponds to the flow of matter, which is related to the inherent properties of the matter itself, and is a non-reversible deformation process; when an external pressure is applied to an object, the changes in the shape and volume of its internal parts are elastic, which is a reversible deformation process. [0003] Currently available rheometers on the market are divided into rotational rheometers, capillary...

AI Technical Summary

Problems solved by technology

However, interface rheometers, especially interface expansion rheometers, generally use manual operations to load the pull-out force by pulling up with a spring balance, because the spring is inherently difficult to control stretching, retraction, and rebound. Such defects lead to extremely unstable loading force, and indirectly make the stability of displacement acquisition worse, and because of manual operation, the heating process is exposed to the external environment, resulting in extremely unstable temperature

The present invention aims to overcome the above-mentioned defects. At present, in the field of research on the rheological characteristics of liquid and semi-solid materials, there is no measuring device similar to the present invention. Therefore, the application of the present invention in this field has a strong urgency , will play an active and effective role in promoting research and development in this field
