Rheological property testing method for semi-solid material with flat/decorative surface

Abstract

The invention discloses a rheological property testing method for a semi-solid material with a flat / decorative surface. The rheological property testing method adopts a rotary rheometer for testing, and comprises the steps of: gradually reducing a gap between an upper clamp and a lower clamp of the rotary rheometer so as to compress a semi-solid material sample loaded on the lower clamp; and testing the rheological property of the semi-solid material sample for several times continuously or at intervals in the process of gradually compressing the semi-solid material sample. The rheological property testing method simulates the process of worker / machine construction, tests the rheological property of the semi-solid material to obtain rheological parameters with higher reference value in theprocess of gradually compressing the semi-solid material sample, and tests the rheological property of the semi-solid material for the actual using situations thereof in the process of compressing the semi-solid material sample, thereby acquiring the rheological parameters with higher reference value.

Description

technical field [0001] The invention relates to the field of engineering materials, in particular to a method for testing rheological properties of semi-solid materials with flat / decorated surfaces. Background technique [0002] In the process of rheological testing of existing fluids, after the gap between the upper and lower plates of the rotational rheometer is controlled to a set gap, the lower clamp is controlled to rotate, and the material clamped between the upper clamp and the lower clamp is sheared. Fluid, in this process, obtain a set of raw data for detection, and perform data processing according to this set of raw data to obtain the final rheological parameters. This test method is the most basic test principle, but it is actually used in different fields This test method does not solve the actual problem very well; [0003] For example: in the field of semi-solid materials, if the traditional rheological performance test method is adopted, that is, the upper / l...

Problems solved by technology

[0005] We previously proposed a technical scheme to establish a relationship model between putty rheological parameters and corresponding construction performance, so as to directly obtain objective construction performance information according to the rheological parameters of putty samples. However, in the actual practice process, the traditional The rheological parameters obtained by the rheological performance test method and the corresponding construction performance data are not highly repeatable, and then we optimized the scheme, because we did not take the actual construction process into account in the experiment, in the actual construction process , putty is in a dynamic process of shape change, and its rheological properties are different from those in static state
