摘要
考察了硫化氢对喷气燃料银片腐蚀的影响 ,同时对硫化氢与其它硫化物共存对银片腐蚀情况进行了研究。结果表明 ,当硫化氢浓度为 1.5 μg/g时就能产生严重的银片腐蚀 ,而不同结构的硫醇和二硫化物单独存在且含量不超过 40 μg/g ,在低温下不会产生银片腐蚀 ,但它们分别与硫化氢共存时 ,含量为 2 0 μg/g硫醇能加剧硫化氢对银片的腐蚀 ,而含量高达 40
Influence of hydrogen sulfide on silver strip corrosion of jet fuel has been investigated. Meanwhile the difference of corrosion phenomenon has been studied when hydrogen sulfide coexisted with other sulfide. The results show that the serious silver strip corrosion could be caused by 1.5 μg/g hydrogen sulfide, however, when the different structural mercaptan and disulfide existed alone and their content was less than 40 μg/g at low temperature no silver strip corrosion occurred. When they coexisted with hydrogen sulfide respectively, 20 μg/g mercaptan could aggravate the hydrogen sulfide corrosion, but the content of disulfide up to 40 μg/g still had no influence on hydrogen sulfide corrosion.
