高密度燃料HDF-1与橡胶的相容性研究
-
摘要: 报道了在室温和70 ℃下橡胶材料G402氟硅胶、丁腈胶5171、丁腈胶4170、贮囊橡胶用合成的高密度燃料HDF-1浸泡后性能如伸长率、邵尔硬度、重量、面积体积的变化，并与采用3号喷气燃料（RP-3）实验结果进行对照。用红外光谱测定了燃料浸泡前后橡胶组成的变化。实验结果表明，G402氟硅胶和贮囊对于HDF-1和RP-3有相近的相容性，丁腈胶5171对HDF-1的相容性比对RP-3的相容性稍差，丁腈胶4170对HDF-1的相容性比对RP-3的相容性更差的结果。因此，丁腈胶5171和丁腈胶4170不能用于HDF-1储存和输送，原使用RP-3系统的橡胶密封件不能直接使用HDF-1。Abstract: In the study of the application of high-density fuel HDF-1, the compatibility of rubbers used in the system with fuel HDF-1 is one of important issues because it directly affects the storage, transportation and use of fuel HDF-1. This paper reports the effects of fuel HDF-1 on the rubbers such as nitrile rubber 4170, nitrile rubber 5171, fluorinated silicone rubber G402 and container rubber at room temperature or 70 ℃ and comparison of the results with No.3 jet fuel (RP-3).The rubbers were characterized by FTIR. The results show that fluorinated silicone rubber G402 and container rubber are compatible with fuel HDF-1 and fuel RP-3. Fuel HDF-1 is less compatible with nitrile rubber 5171 than fuel RP-3, and fuel HDF-1 is least compatible with nitrile rubber 4170. Therefore, nitrile rubber 4170 and nitrile rubber 5171 are not suitable for the storage and transportation of fuel HDF-1, the rubbers used in the fuel RP-3 system cannot be directly used in the fuel HDF-1 system.
