一、冷却水对金属腐蚀的影响在任何一种水中,溶解氧是碳钢腐蚀的主要因素,它将导致碳钢的全面腐蚀;其次是氯化物和硫酸盐。硫化物和铵盐也是不可忽视的重要因素。虽然它们通常是很少含在天然水中,可是在特定的环境中却含有硫化物或铵盐。例如,在所用的循环冷却水中有硫酸盐还原菌存在时,常常能发现水中有硫化氢存在。天然水中的钙盐、镁盐虽是导致 Effect of Cooling Water on Metal Corrosion In any type of water, dissolved oxygen is a major factor in the corrosion of carbon steel, which causes total corrosion of carbon steel; followed by chloride and sulfate. Sulfides and ammonium salts are also important factors that can not be ignored. Although they are usually rarely contained in natural waters, they contain sulphides or ammonium salts in certain environments. For example, in the presence of sulfate-reducing bacteria in the circulating cooling water used, the presence of hydrogen sulphide in the water can often be found. Although calcium salt in natural water, magnesium salt is caused
