Description
Technical field
It the utility model is related to polymeric material field, more particularly to a kind of high polymer material coefficient of cubical expansion is simple
Test device.
Background technology
The swelling that high polymer material occurs under Elevated Temperature Conditions is " thermal expansion ".When temperature raises, molecular motion
Mean kinetic energy increase, intermolecular distance also increases, and the volume of high polymer material expands therewith.The coefficient of expansion is to characterize object
When heated, its length, area, Volume Changes degree and the physical quantity that introduces；It is swollen that the coefficient of expansion includes linear expansion coefficient, face
Swollen coefficient and the coefficient of volume expansion.When the temperature of high polymer material changes 1 degree Celsius, the change of its volume and its body at 0 DEG C
The ratio between product, is called " coefficient of cubical expansion "；Due to the coefficient of expansion very little of solid or liquid, for the sake of convenience of calculation, in temperature
When not very high, volume v during without asking 0 DEG C again0, directly can be calculated with following formula：
v2=v1[1+αv(T2-T1)]
Wherein：V in formula1It is in T1DEG C when volume, v2It is in T2DEG C when volume, coefficient of cubical expansion αvUnit be k-1。
GB/T 1036-2008 define the method for testing of linear expansion coefficient of plastics.Because liquids and gases do not have fixation
Shape, thus the conventional coefficient of cubical expansion represents their degrees of expansion；But for high polymer material, the coefficient of cubical expansion
And extremely important parameter.But the research for the high polymer material coefficient of expansion at present, it is typically limited to linear expansion coefficient
Test and sign；And the actually sign of the high polymer material coefficient of volume expansion, no matter in theoretical research or application aspect,
It is significant.Only pressure-volume-temperature (PVT) instrument of the seen test macromolecule coefficient of cubical expansion at present, but
It is expensive, and have particular/special requirement to test sample, test condition is also very strict；Therefore it is badly in need of a kind of easy high polymer material
The test device of the coefficient of cubical expansion.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of high polymer material body simple in construction
The tester of the product coefficient of expansion.
The utility model solves its technical problem and is achieved through the following technical solutions：Including an oil bath pan, one
With the digital display temperature measurer of external probe wire and a capillary glass dilatometer；Capillary glass dilatometer is by a band ground
Hyaloid QC and one with ground it is with a scale capillary glass tube composition；The hyaloid QC of capillary glass dilatometer is put
In the inside of oil bath pan, the probe induction point on the external probe wire of digital display temperature measurer is placed in capillary glass dilatometer lower end glass
The middle part of glass sample cell.
The beneficial effects of the utility model are：Start oil bath pan, capillary glass dilatometer one is supplied to by oil bath
Lasting elevated temp；The material of capillary glass dilatometer is high-boron-silicon glass, have low thermal expansion, high temperature resistant, high intensity,
The characteristics of high transmission rate and high chemical stability, it is possible to reduce experimental error；Temperature-rise period is tested by the capillary with imprinting
The micro volume change of tester, senses and shows reality by the external probe wire of digital display temperature measurer in middle hyaloid QC
Temperature is tested, obtains Volume Changes-temperature curve in heating test process, it is convenient and swift.
Using the Simplified Test Equipment that the utility model is related to, when testing the high polymer material coefficient of cubical expansion, it is necessary to
Difficult volatilised liq from insoluble high polymer material tester is medium, and indirectly testing goes out the volumetric expansion system of high polymer material
Number.Concrete operation step is as follows：Quantitative liquid medium is fitted into the hyaloid QC of capillary glass dilatometer first, capillary
The hyaloid QC of pipe glass swelling meter is placed in the inside of oil bath pan, the probe induction point on the external probe wire of digital display temperature measurer
The middle part of capillary glass dilatometer lower end hyaloid QC is placed in, the Volume Changes then obtained according to test-temperature is bent
Line, calculate the coefficient of cubical expansion for obtaining liquid medium；Then high polymer material tester and quantitative liquid medium will be quantified together
It is placed in the hyaloid QC of dilatometer, tests total volume of high polymer material tester and liquid medium in temperature-rise period
Change-temperature curve, from total volumetric expansion data, Volume Changes caused by liquid medium are deducted, that is, obtain macromolecule material
Expect the volume change of tester, with reference to the temperature difference in temperature-rise period, can be calculated the coefficient of cubical expansion of high polymer material.
