The protective effectiveness of oil compositions in the presence of sulfur dioxide was studied. The moisture permeability of oil films and the corrosion rate of steels both protected and unprotected by oil films increase with increasing relative humidity and initial sulfur dioxide concentration in the atmosphere. The contribution of individual components to the protective effect of a film of synthetic Mobil-1 oil inhibited by the additive Emulgin in the presence of sulfur dioxide is considered. The total protective effectiveness of the system can reach 93-96% after one day in 0.5 M sodium chloride solution containing sulfur dioxide and the products of its interaction with water. The slowdown of steel corrosion under a layer of inhibited and non-inhibited oil film is mainly due to retardation of the cathodic process with slight inhibition of the anodic reaction.

油组合物在含硫腐蚀刺激剂存在下的保护效果

研究了在二氧化硫存在下油组合物的保护效果。油膜的透湿性和受油膜保护和未受油膜保护的钢的腐蚀速率随着相对湿度和大气中初始二氧化硫浓度的增加而增加。考虑了在二氧化硫存在下，添加剂 Emulgin 抑制的合成 Mobil-1 油膜保护作用的各个组分的贡献。在含有二氧化硫及其与水相互作用产物的 0.5 M 氯化钠溶液中，一天后该系统的总保护效率可达 93-96%。
