活性硫对喷气燃料银片腐蚀影响的研究

A Study of the Influence of Active Sulphur on Silver Strip Corrosion of Jet Fuel

考察了硫化氢、元素硫、硫醇、硫醚、多硫化物等单独存在时对喷气燃料银片腐蚀的影响;同时考察了元素硫与其它硫化物以不同浓度混合时对喷气燃料银片腐蚀的影响。试验结果表明,硫化氢、元素硫是导致喷气燃料银片腐蚀不合格的主要原因。当元素硫和硫化氢单独存在时,元素硫的浓度只要大于0.5μg/g、硫化氢的浓度只要大于1.5μg/g,喷气燃料银片腐蚀就不合格。当与其它硫化物共存时,其它硫化物只起着协同的作用。

Influences of hydrogen sulfide, element sulphur, mercaptan, sulphuring ether, disulfide respectively on silver strip corrosion of jet fuel, and of element sulphur coexisting with other sulfide on silver strip corrosion of jet fuel has been studied.The results show unquanification of silver strip corrosion of jet fuel mainly results from hydrogen sulfide and element sulphur. And when the concentration of the hydrogen sulfide and element sulphur are larger than 1.5 μ g/ g and 0.5 μ g/ g respectively, silver strip corrosion of jet fuel is unquanlified. Other sulfides only play cooperation on the unqualificaiton of jet fuel.
