与丁腈橡胶一样氟橡胶是制造密封圈、O型圈和胶管等接触汽车燃料不可缺少的材料。若汽油与含氧的乙醇混合,在乙醇浓度达到20%~30%时可观察到橡胶溶胀的最大值。虽然,我们已见到关于ETBE、甲醇和MTBE等物质浓度的影响的报告,但有关与含氧成分混合的研究报告却未见报道。下面就甲醇和MTBE混合的影响问题作一讨论。将异辛烷和甲苯混合的燃料(混合比例4:6)作为基本汽油。分别制备两组混合燃 Fluorine rubber, like nitrile rubber, is an indispensable material for making seals, o-rings and hoses that come in contact with motor fuels. If gasoline is mixed with oxygenated ethanol, the maximum value of rubber swelling is observed at ethanol concentrations of 20% to 30%. Although we have seen reports of the effects of concentrations of substances such as ETBE, methanol and MTBE, no studies on the mixing with oxygen-containing components have been reported. The following discussion of the impact of methanol and MTBE blends is discussed. A mixture of iso-octane and toluene (4: 6) was used as base gasoline. Preparation of two groups were mixed combustion
