摘要:

研究利用餐饮余油,采用脂肪酸加氢工艺合成的生物燃料组分对飞机油箱密封胶性能的影响。实验结果表明,重铬酸盐固化聚硫密封胶和锰固化聚硫密封胶在生物燃料组分93℃的环境温度中浸泡28 d后,其硬度明显增加,断裂伸长率明显减小,体积出现较大收缩。当生物燃料组分与传统喷气燃料按照50/50 体积比掺混后,重铬酸盐固化聚硫密封胶体积膨胀率从-3.0%增加到-0.5%,而锰固化聚硫密封胶体积膨胀率从-6.7%增加到-5%。其各自的硬度,断裂伸长率也均发生了明显变化。

Abstract:

The effects of Bio-SPK derived fromfood residualoilon the propertiesof aircraft fuel tank sealants are systematically studied. The results indicate that after soaking in Bio-SPK component at 93℃for 28 days,the hardness of dichromate cured polysulfide sealant and manganese cured polysulfide sealant greatly increased while the ultimate elongation and volume of those two sealants decreased significantly. When soaking in the fuel with 50/50 volume ratio of Bio-SPK and traditional jet fuel,the volume swell of dichromate cured polysulfide sealant increased from -3.0% to -0.5% while the volume swell of manganese cured polysulfide sealant increased from-6.7% to -5%. The hardness and ultimate elongation of those two sealants also changed obviously.

Key words: bio-SPK, bio-derived aviation turbine fuels, aircraft, fuel tank sealants
