Description
Technical field
The utility model belongs to high molecular material thermal energy determination techniques field, and in particular to a kind of heat distortion temperature experiment dress
It sets.
Background technique
Heat distortion temperature is to apply certain load to high molecular material or polymer, corresponding when reaching regulation deformation
Temperature, be a kind of measurement for measuring high molecular material or polymer heat-resistant superiority and inferiority.
To realize sample during the test, temperature at the uniform velocity rises, and the mode of conduction oil is commonly used.It will test
Sample is placed in oil groove together with sample stage, is heated by the heating tube in oil groove to conduction oil, and thermally conductive oil temperature is from normal
Temperature is gradually increasing, and the temperature of sample applies sample by force loading device in temperature ramp de also with rising at this time
Certain load reaches heat distortion temperature when regulation deformation to test.However, after the completion of test sample measurement, in oil groove
Temperature is still very high (up to 300 DEG C of test temperature), and needs to measure since room temperature when a sample under measuring, thermally conductive oil temperature
Degree is down to room temperature and needs the long period, thus causes the interval time for measuring lower a sample long, influences experiment process.
Utility model content
The purpose of this utility model is that solve the deficiencies in the prior art and provides a kind of thermal change that can be quickly cooled down
Shape temperature experimental provision.
The purpose of this utility model is realized with following technical proposals:
A kind of heat distortion temperature experimental provision, including experimental box body set sample stage, force loading device and oil bath in cabinet and add
Thermal, body side and bottom surface are Double-layer clamp core type, set inlet and outlet in double layer sandwich, are additionally provided with cooling in cabinet
Water-circulating pipe, cooling water-circulating pipe inlet end and an outlet end are respectively positioned on outside cabinet, and input end, outlet end are L-type.
Discharge outlet is set on the outside of tank floor.
Tank floor is arc.
Cooling water-circulating pipe and cabinet junction set sealing ring.
Double layer sandwich box inside face is Heat Conduction Material, and lateral surface is thermal insulation material.
Heat distortion temperature experimental provision provided by the utility model is set cold by setting double layer sandwich cabinet and in cabinet
But water-circulating pipe can quickly take away conduction oil by being passed through cooling circulating water in double layer sandwich cabinet and cooling water-circulating pipe
Interior heat, cools down conduction oil rapidly, can measure lower a sample rapidly, accelerates experiment process.

Specific embodiment
Heat distortion temperature experimental provision provided by the utility model sets sample in cabinet as shown in Figure 1, including experimental box body 1
Sample platform 2, force loading device and oil bath heating device, body side and bottom surface are Double-layer clamp core type, preferably in double layer sandwich cabinet
Side is Heat Conduction Material, and lateral surface is thermal insulation material；Water inlet 3 and water outlet 4 are set in double layer sandwich, are additionally provided with cooling in cabinet
Water-circulating pipe 5, cooling water-circulating pipe input end 6 and outlet end 7 are respectively positioned on outside cabinet, and input end, outlet end are L-type.
It, can be by inlet and outlet to double when needing to measure lower a sample rapidly after the completion of the measurement of upper a sample
It is passed through recirculated cooling water in layer is sandwich, the heat in conduction oil is taken away by recirculated cooling water, while can be to the intracorporal cooling water of case
Circulation pipe is also passed into recirculated cooling water, accelerates distributing for the heat in conduction oil, make conduction oil can fast cooling, it is next to carry out
The measurement of sample.Water circulating pump 8 can be connected in the water outlet in double layer sandwich can be further in case conducive to the circulation of cooling water
Body outer side bottom surface sets discharge outlet 9, and to facilitate the cooling water in discharge double layer sandwich, preferably tank floor is set as arc, makes to cool down
The more convenient discharge of water.
Cooling water-circulating pipe inlet end and an outlet end is set as L-type, when needing using cooling water-circulating pipe, can easily by
It is supported in top of the box, can conveniently be drawn off when not needed.Cooling water-circulating pipe and cabinet junction can set sealing ring
10, it prevents junction from having the gap, influences cabinet insulation performance.Equally, cooling water-circulating pipe outlet end can connect water circulating pump, with
Conducive to water circulation.
Any money product of the prior art can be used in the utility model sample stage, force loading device and oil bath heating device, only
It is able to achieve its corresponding function.As shown in Figure 1, on the support frame 11 arranged in the box body of sample stage 2, to support sample
Product 15；Force loading device includes the load bracket 12, power loader 13, load bar 14 being set to outside cabinet, 14 bottom of load bar
Go deep into cabinet, to apply pressure to sample, certain the utility model further includes not depending on out to complete heat distortion temperature
Other well-known components of measurement, such as the oil bath heating device (heating wire can be used) to heat conduction oil, lead to control
The temperature control system of hot oil temperature, the conduction oil agitating device to make conduction oil flowing, there are also to characterize deformation parameter
Displacement sensor, amesdial etc., the product that money any in the prior art is able to achieve above-mentioned function can be selected in same above-mentioned component
