Description
Technical field
The present invention relates to the test devices and method of a kind of swellbility, and in particular to one kind is for macromolecule swellbility intelligence
Dynamic checkout unit and test method belong to high molecular chemical characters characterization technique field.
Background technology
Cross-linked polymer has swelling character, and swelling equilibrium is substantially the thermodynamical equilibrium of cross-linked network and solvent, this
Kind dynamic equilibrium can change with extraneous factors such as solvent environment, temperature.Crosslinked polymeric swellbility is measured, for research
Interaction and high molecular swellability between polymer crosslinking structure, macromolecule and solvent, which are influenced by temperature etc., all to be had
It is significant.
The swellbility test method of document report mainly has weight method and two kinds of volumetric method of amount at present, mostly using laboratory
Easily-testing lacks general standard method of test and instrument.Weight method be by the polymer of known quality within a certain period of time
It is soaked in solvent, rapid filtration under suction removes excess of solvent after it reaches swelling equilibrium, and polymerization is assessed by calculating gain in weight
The swellbility of object.This kind of procedure is complicated, and accurate testing degree is not high, it is impossible to which how solution isolates swelling body from solvent
The problem of without influencing its swelling equilibrium state, and the continuous dynamic change of swellbility at any time cannot be recorded in real time.Measure volume
Method is usually to select the graduated glass column of a fixed-caliber, and volume information is changed into elevation information, is a kind of more simple and conjunction
The test method of reason, but can not equally realize that the continuous dynamic of swellbility is tested in a manner that scale value is read in range estimation at present,
Accuracy and intelligent level be not high.Therefore, designing a kind of novel swellbility test method and device has important practicality
Value.
Invention content
The present invention overcomes the deficiencies of traditional swellbility measuring technology, provide a kind of for macromolecule swellbility Intelligent Dynamic
Test device and test method, to fill up the blank of current swellbility Intelligent Dynamic test method and instrument.
One of the objects of the present invention is to provide a kind of swellbility Intelligent Dynamic test device, including：

It should be noted that step 1. in, using circular gasket with holes, it is with holes be in order to solvent from hole penetrate into specimen cup,
Sample is infiltrated, sample infiltration could be swollen in a solvent.Hole requirement is small and more.It is to cover pad to put a filter paper simultaneously
The hole of on piece avoids powder sample from being packed into powder sample when being suppressed in specimen cup and leaks out, and solvent is to penetrate filter paper to reach sample
Product.
Step 5. in, sheet sample due to surface contact solvent and first start be swollen and become shapeless, pass through place one
Filter paper is opened, is to be pressed on sample, to ensure the smooth of sample upper surface, ensures that the displacement data tested is accurate.
Step 6. in, after suppressing sample, specimen cup, gasket, filter paper, sample are hung over as an entirety on hanger.Cause
This this device is to provide two sets of specimen cups for oneself, and test is directly hung up after pressing sample.Sheet sample is powder sample in specimen cup
Interior direct pressing molding, therefore diameter is identical with specimen cup.Disk diameter is tested no more than sample diameter, specimen cup can be put in
It is interior.
Compared with prior art, the beneficial effects of the invention are as follows：The swellbility Intelligent Dynamic test method and dress of the present invention
Put the deficiency for overcoming conventional test methodologies, realize that paperless intelligent data acquire by being connect with computer, operation it is simple and
It realizes big data quantity follow-on test, reduces cost of labor；A variety of shapes such as powder, bulk can be used in the strong applicability of sample to be tested
The sample of state；Test overall process is all not required to detach sample with solvent, operates simple and data accuracys and favorable reproducibility；Knot
Double jacketed glass cup is closed, connection temperature control device can realize the swelling character research of macromolecule at different temperatures；Using bilateral
Road can test two samples to improve testing efficiency simultaneously.
