Abstract

Se ha encontrado que una combinación de (i) un componente inhibidorprimario de aminas y/o sales de amonio cuaternarias no carcinológicas y debaja toxicidad con (ii) un componente secundario de materiales depolarización tales como compuestos orgánicos que contienen sulfurodivalente, surfactantes aniónicos y iones de yoduro y bromuro proporcionauna inhibición satisfactoria en soluciones de limpieza química ácidafuerte para acero, mientras reduce el peligro de su empleo asociado conlos inhibidores de limpieza química más usados de la técnica anterior.It has been found that a combination of (i) a primary inhibitory component of non-carcinogenic quaternary amines and / or ammonium salts and low toxicity with (ii) a secondary component of depolarizing materials such as sulfurodivalent-containing organic compounds, anionic surfactants, and ions of Iodide and bromide provide satisfactory inhibition in strong acidic chemical cleaning solutions for steel, while reducing the danger of their use associated with the more widely used chemical cleaning inhibitors of the prior art.
