摘 要：利用热重-差示扫描量热法（TG-DSC)对薄型、超薄型各3个型号未知配方的防火涂料进行分析，薄型涂料水分及挥发性溶剂较超薄型涂料少。残留质量能够反映稳定性，薄1型、薄3型残留质量显著大于其 他4个型号的涂料，因此稳定性更优。薄型、超薄型涂料所含季戊四醇、聚磷酸铵、三聚氰胺的含量均有所差 异...
Thermogravimetric-Differential Scanning Calorimetry Analysis (TG-DSC) was applied to study non-isothermal pyrolysis characteristics of oil shales, such as the starting point, stability, pyrolysis interval and product release using Fuyu and Huadian oil shale samples. Results show that with the increase ...

back to historical data. Similarly, if testing to a specification or industry standard, the technique and test parameters must be well defined. Even within a test technique, the means of obtaining the Tg can be performed various ways and the result can vary significantly. The Tg by DSC, TMA...
The TG-DSC technique is also employed to investigate the effect of different encapsulation patterns of Al crucible (high-pressure encapsulation, low-pressure one, traditional perforated lid one) on the analysis result of gypsum crystal water content. The results show that two dehydration peaks of ...
