摘要
Abstract
Thermoplastic polyurethane(TPU)elastomers have been widely used in the storage and transportation of pe-troleum products due to their excellent wear resistance and solvent resistance.During the storage and transportation pro-cesses of jet fuel,The TPU equipment has to face various complex transportation environments.In such processes,the TPU hoses may be affected by the dual effects of jet fuel and ultraviolet radiation.If this impact causes their thermal char-acteristics to no longer meet the demand and results in an economic loss and environmental problems.Therefore,the im-pact of jet fuel on the thermal performance of TPU during storage and transportation cannot be ignored.In this study,dif-ferential scanning calorimetry and thermogravimetry analysis were conducted to investigate the thermal performance of the TPU treated with jet fuel and UV irradiation.The results indicated that a long-term immersion in jet fuel led to an in-crease in the glass transition temperature and a decrease in the thermal stability of TPU.After treatment with jet fuel,the TPU samples exhibited an exothermic peak at 150℃as a result of the presence of crystallization.关键词
