Description
Technical Field
[0001] The utility model relates to the technical field of phase change temperature detection, and particularly relates to a phase change temperature detection device. Background Art
[0002] The phase change temperature refers to the temperature at which a phase transition occurs. At the phase change temperature, the fluidity of the membrane lipid will change accordingly, changing from the liquid phase to the gel phase or from the gel phase to the liquid phase. Generally, the arrangement form of molecules in a solid material is also related to temperature, and there are also many phases, and phase transitions will also occur. At this time, the crystal form will change at the phase change temperature.
[0003] At present, the main methods for measuring the phase change temperature are: dilatometry; X-ray diffractometry; thermal analyzer method; resistance method; metallographic method. For the phase change evaluation of gels, the stirrer method is mostly used to measure the gel temperature. The physical change of gel formation, that is, the significant increase in viscosity when changing from a liquid to a solid, can measure the gelation temperature of the thermosensitive gel in this way.
[0004] However, this method requires a relatively large amount of samples, is relatively inconvenient to operate, and due to the non-uniform stirring speed and the limitations of temperature rise and fall, the obtained results may be inaccurate.
[0005] In addition, a rheometer can also be used to detect the phase change temperature. This detection method is more accurate and can also measure data such as viscosity at the same time. However, the rheometer equipment is relatively complex, has a high price, and also requires professional maintenance personnel and equipment maintenance. The test cost is relatively high, the test sample volume is relatively large, and it is not convenient to use.

[0044] The temperature adjustment mechanism is provided with a switch 25, a temperature adjustment knob 21 and a rotation speed adjustment knob 22.

[0053] Functions and effects of the embodiment
[0054] According to a phase change temperature detection device involved in the present utility model, the user loads the sample through the phase change tube and provides a constant-speed pushing force at the same time.

The overall operation of the device is simple, the cost is low, and it is more widely applicable.
[0055] The connection mode between the phase change tube and the feeding device and the pushing device is a detachable connection.
