Problems solved by technology

The above methods measure the phase change of the material through the acoustic wave propagation characteristics and the change of the material resistivity respectively, but there is a problem in these methods: they only work normally under standard atmospheric pressure, so they can only detect the phase change and temperature of the material under normal pressure. relationship, which cannot be applied to high-voltage detection scenarios, ignoring the high-voltage factor

Abstract

The invention discloses a device for detecting phase transition of materials under high pressure. The device consists of three parts: light source bin, material bin, photoelectric detection and temperature control unit. When the device is working, it is placed in a pressure regulating container, and the external pressure is transmitted to the material to be tested in the material bin through the soft bag. The temperature in the material bin is regulated by the internal temperature control unit. When the device is working, the light source produces parallel light rays, which illuminate the material to be tested in the material bin vertically, and the light transmittance of the material under different pressures and temperatures is measured by the photoelectric detection unit. The data analysis and processing of the light transmittance signal can obtain the continuous phase transition state of the material under different pressures and temperatures. 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 ...
