差示掃描量熱技術(shù)分析高壓下的氧化誘導(dǎo)時(shí)間
|
| A series of high pressure oxidative induction time measurements (HPOIT) were conducted on a polyethylene geomembrane sheet in order to investigate the interaction of the pressure and temperature variables on the induction time. The experiments consisted of determining the HPOIT at constant cell volume employing a wide operational range of pressure and temperature values. The HPOIT test results were found to be inversely related to both variables, with temperature being the predominant factor. A modified Arrhenius model was constructed from the data to account for both the temperature and pressure dependency of the HPOIT test. |
