摘要:

热机械分析仪(TMA)能连续测量煤灰加热过程中探头的位移率和位移速率,可以观察煤灰在整个加热过程中的熔融特性,与采用传统熔点测定仪(AFT)方法相比,能够避免操作者的主观影响,可以提高熔融性测试的重复率和再现性。

Abstract:

Thermo-mechanical analysis(TMA) can determine the transport ratio and rate of displacement of probe in the process of heating of coal ash continuously and can observe the melting point of coal ash in the whole process of heating. In comparison with the traditional ash melting point temperature tester(AFT) method, TMA can avoid the subjective influence of operator and improve the repetition rate and reproducibility of melting point determination.
