Introduction: The JH-II-2 high temperature contact angle analyzer is a high temperature, transmission projection device used to measure the surface wetting phenomenon of different materials in a specific temperature environment and the surface contact angle of metal materials. It can be used for a variety of metals, inorganic compounds or their mixtures. During the heating process, the contour changes during the whole process of sintering, softening, melting and liquefaction are monitored. The image of the sample and its related temperature, height and other information can be stored in real time, and it can provide reference data for the calculation of surface tension and infiltration angle. . The instrument has high temperature measurement accuracy and test repeatability, and is suitable for the research department to test the high temperature physical properties of materials. The instrument has a high degree of automation, simple and reliable operation, and is especially suitable for routine production testing in metallurgy, chemical, power generation, coal and other enterprises. technical parameter: 1: The image of the test sample is collected by the CCD camera and displayed on the computer screen. During the heating process, all changes in the sample profile can be observed on the computer screen; 2: Temperature measurement range: 0℃~1550℃, the long-term use temperature is below 1450℃; 3: Temperature measurement accuracy: ±0.2% (full scale); 4: Temperature resolution: ±1℃; 5: Using molybdenum wire (under protective atmosphere), the limit temperature can reach 1650℃. Type B thermocouple 6: The heating adopts microprocessor program to control the temperature, and the temperature control thermocouple adopts the S-type thermocouple, which is placed in the furnace wall and led out by the terminal. The temperature control process is determined by the temperature control curve pre-set on the temperature controller, or it can be controlled manually; 7: The lighting source adopts 220V special white light source with adjustable brightness; or fixed brightness. 8: The temperature control system is concentrated in the temperature control cabinet, and the power supply is single-phase 220V, frequency 50Hz; 9: The instrument is equipped with over-temperature protection and over-current protection. 10. JH-II-2 high temperature contact angle analyzer is used to analyze the contact angle of different material interfaces under different temperature conditions, and the analysis and processing are completed by computer programs.
