Abstract

The present invention discloses a high-pressure-oriented phase change state detection device. The device is composed of a light source bin, a material bin, and a photoelectric detection and temperature control unit. When working, the device is arranged in a pressure-regulating container; external pressure is transmitted to a material to be tested in the material bin through a soft bag; temperatureinside the material bin is adjusted by an internal temperature control unit; when the device is working, the light source generates parallel light which vertically illuminates the material to be tested in the material bin; the light transmittances of the material under different pressures and temperatures are measured through a photoelectric detecting unit; and light transmittance signal data areanalyzed and processed, so that the continuous phase transition state of the material under the different pressures and temperatures can be obtained. The device provides effective data support for the selection of phase change buoyancy materials.

Description

technical field [0001] The invention relates to the field of material phase change detection, in particular to a phase change state detection device under high pressure. Background technique [0002] The process of a substance changing from one phase to another is called a phase transition. A phase change changes the volume of an object. Temperature and pressure are the two major influencing factors of phase transition. When the temperature is constant, the pressure will affect the melting point and boiling point of the material, thus affecting the phase transition of the material. [0003] At present, there are ultrasonic detection methods, electrical (resistance) detection methods, etc. for material phase change detection methods. The above methods measure the phase change of materials through the acoustic wave propagation characteristics and the change of material resistivity respectively, but there is a problem in these methods: they only work normally under standard ...
