大型钢结构在海洋大气、工业大气中的腐蚀特点

工业用气体含有SO2·······H2S排放权NO2 CI2及NH3等成分含量虽然很小,但是,钢铁,腐蚀的危害都不可忽视的SO2中影响最大的有了CI2金属表面上破坏了这些气体。溶于水呈酸性(形成酸雨,腐蚀金属设施。
海洋大气的特点是含有大量的盐,主要NaCI盐颗粒在金属表面具有吸湿性及增加表面液膜的传导作用,同时企业本身-又有很强的侵蚀性,因此了金属表面的腐蚀钢筋的海岸上。更近一点,更严重的腐蚀。腐蚀速度双内陆大气中问题很多倍高。
Under the effect of atmospheric environment, the steel bar, sand, Yu Xue, cream syrup and the temperature and humidity changes, the air in the air and moisture damage, corrosion of surface steel structure is an important factor in the electrochemical corrosion.
CI2, H2S and SO2, etc., are very small, but the damage of NO2 and NH3 can not be ignored. The impact of SO2 on the most important CI2 metal surface has been destroyed. Dissolved in water is acidic (form acid rain, corrosion of metal facilities.
Marine atmosphere is characterized by a large amount of salt, the main NaCI salt particles in the metal surface with a moisture absorption and increase the conduction of the surface film, while the enterprise itself - and have a strong erosion, so the metal surface of the corrosion on the coast. Closer, more serious corrosion. The corrosion rate is many times higher than in the interior of the atmosphere.
