1)  isothermal degradation
等温热降解
1.
The thermal stability of POM/COPA and POM/SAN/PA were studied in both nitrogen and air atmosphere by isothermal degradation at 220 ℃ and constant heating rate thermogravimetric analysis(TGA).
结果表明,加入稳定剂COPA、PA的聚甲醛体系在220℃等温热降解1h的失重率远小于空白POM;TG分析数据也显示改性后的聚甲醛体系在氮气中的Tonset明显高于空白POM,空气中空白POM的活化能及分解温度均低于改性聚甲醛。
2)  quick pyrolysis
等温热解
3)  Thermal degradation temperature
热降解温度
4)  non-isothermal degradation
非等温热解
1.
The non-isothermal degradation of polyethylene-octene elastomer(POE)/gelatinized waxy corn starch(GWCS) blends with different compositions was first carried out in an inert atmosphere,and the corresponding degradation behaviors and kinetics were investigated by means of the thermogravimetric(TG) method.
利用动态热重分析(TG)技术对乙烯-辛烯共聚物(POE)/糊化蜡质玉米淀粉(GWCS)共混物在惰性气体条件下的热性能和非等温热解动力学进行了分析,探讨了其热解机理。
5)  linear heating rates
平衡热降解温度
1.
The degradation process of Cl PP with different Cl content in N 2 and air in linear heating rates have been studied by using TG DTG DSC.
用TG-DTG-DSC法研究了低氯化聚丙烯(Cl-PP)在空气、N2气流中线性升温时的热降解,发现随Cl%增加,主链脱HCl的失重率增大,而主链的降解失重率减小;N2气中平衡热降解温度T0p1、T00。
6)  low temperature thermo-oxidation degradation
低温热氧化降解
补充资料:等温热脱附
分子式:
CAS号:

性质:在不改变温度的条件下吸附质从吸附剂表面所进行的脱附,一般是加热到某一温度后,以气体吹扫或抽真空方式使吸附物脱除。在脱附过程中适当补充热量,使体系保持恒温。这是区别于程序升温脱附的一种脱附方式。
