Adsorption Inhibitors of Acid Iron Corrosion

摘要: By definition, corrosion inhibitors are soluble substances which, added to the aggressive solution, reduce rate without participating in overall reaction. As they not reactants reaction negative catalysts. In this chapter we shall deal with such as sodium carbonate, or other increasing pH of solution and favoring spontaneous passivation, hydrazine a reagent reducing dissolved oxygen thus removing species many neutral-solution processes. Also, disregard components protective paint systems, classical read lead oxide, Pb3O4, an intensely oxidizing again aiming at passivating iron steel surfaces. Instead, object will presently be mechanism protection by acid acting through adsorption on metal surface from containing inhibitive substance millimolar even smaller concentration only. The typical industrial application is hot-rolled against heavy loss during pickling. Another important underground gas oil well piping accompanying embrittlement attack hydrogen sulfide solutions.
