Description
Technical field
The present invention relates to engineering material field, especially a kind of rheological property of smooth/ostentatious semisolid material
Test method.
Background technique
It is the gap by controlling the upper and lower plates of rotational rheometer to one during the rheological characteristic test of existing fluid
Behind the gap of setting, its lower fixture rotation is controlled, shearing is clamped in the fluid between upper fixture and lower fixture, in this process,
One group of initial data of detection is obtained, and data processing is carried out according to this group of initial data and obtains final rheological parameter, the survey
Method for testing is most basic test philosophy, and is actually all made of the test method not in different fields and can solve
Practical problem；
Such as: in semisolid material field, according to traditional rheology testing method, i.e., in the gap location of setting,
Up/down fixture is rotated to a direction, is obtained test data in this process and is fitted to obtain rheological parameter, but acquired
Rheological parameter be only to show semisolid material state performance parameter under static state, and the semisolid material can not be showed
Expect the rheological property (during compressed) in a dynamic state.

According to the rheological parameter of putty sample it is directly obtained objective workability information, however in actual practice process,
The rheological parameter and the data redundancy of corresponding workability obtained using traditional rheology testing method be not high, then
Scheme is optimized in we, because we do not take into account actual work progress in experiment, in actual construction
In the process, putty is the dynamic process changed in shape, different when rheological property is from static state.
In addition in actual work progress, batch Puttying of the worker usually with batch knife back and forth, rather than always to one
Direction batch Puttying, therefore to obtain more reflecting the workability that semisolid material is shown in the construction process, it is testing
It also needs to simulate this during the rheological property of semisolid material and criticizes the process scraped back and forth.
Finally, worker can also carry out the adjusting of state before batch Puttying to putty in actual work progress,
If carried out being uniformly mixed processing to putty using batch knife, then criticizes and scraped on metope again, therefore by the process in view of actual
The test result with more reference value can be obtained in test process.
In view of this present invention is specifically proposed.

Weighted average calculation obtains final rheological parameter.
Of course, the data handling procedure of controller is not limited to the above process, using other modes to the test number of acquisition
It is allowed according to aggregation of data processing is carried out, all within the scope of the present invention.
It should be noted that semisolid material described in the present invention can be the mixture of solid and liquid, preferably liquid
The content of body is 0-80%, including slurry, paste etc.；
For the explanation semisolid material more prepared, provide explained below:
Semisolid is also known as quasi- solid, although in some aspects be similar to solid (such as can support own wt, keep from
Figure shape), but quasi- solid also just has the property of certain liquid, such as pressure can change and can flow under shape, low pressure
Deng.
Semisolid is also referred to as amorphous solid, because they are different with traditional crystalline solid, is on a microscopic scale
Unordered.
The above is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this patent
Member without departing from the scope of the present invention, when the technology contents using above-mentioned prompt are modified or are modified to
The equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, it is right according to the technical essence of the invention
Any simple modification, equivalent change and modification made by above embodiments, in the range of still falling within the present invention program.
