[0030] Attached below Figure 1-2 Further explain the specific structure and implementation of the present invention:
[0031] A temperature-controllable film mechanical property testing device, which is characterized in that it includes a temperature control part, a deflection measuring part, a pressure loading part, and a specimen clamping structure;
[0032] The temperature control part is arranged outside the pressure loading part; the specimen clamping structure is arranged above the pressure loading part; the deflection measuring part is arranged above the specimen clamping structure.
[0033] The pressure loading part includes a pressure chamber, a flow-sharing plate 6, a test piece table 7, a pressurized air pipe 18, a syringe 17, a base 2, an XYZ axis micro-displacement platform 1;
[0034] The pressure chamber adopts a large-diameter copper tube 5, with an end cover 16 at the bottom and a test piece table 7 at the top;
[0035] A flow-sharing plate 6 is provided in the copper...
Example Embodiment
[0048] Example
[0049] A flow-sharing plate 6 is installed in the middle of the large-diameter copper pipe 5, in which the flow-sharing plate 6 has evenly distributed through holes; the two ends of the copper pipe 5 are sealed and installed with a test piece table 7 and an end cover 16, wherein the test piece table 7 is a round ring with a smooth surface. The middle position of the end cover 16 is processed with a pressurized air pipe 18 connecting hole; the outer side of the copper tube 5 is wrapped in sequence with the electric heating belt 4 and the insulation cotton 3, and the thermostat 15 is connected to the electric heating belt 4 through a lead wire ; Install the pressure sensor 13 on the wall of the copper tube 5 near the test piece table 7; the syringe 17 is connected to the end cap 16 through the pressurized air tube 18; the base 2 is placed on the XYZ axis micro-displacement platform, and the pressure chamber is placed On the base 2, the end cover 16 is on the lower ...
