Abstract
The invention relates to an acid-washing corrosion-inhibition fog inhibitor, which achieves an effect of corrosion inhibition by using combination of methenamine, sodium gluconate and oxalic acid, prevents a steel base body from being subjected to acid corrosion and avoids an over-pickling phenomenon. In the acid-washing corrosion-inhibition fog inhibitor provided by the invention, foam can be generated by combination of dodecyl sodium sulfate, sodium dodecyl benzene sulfonate and AES (Sodium Alcohol Ether Sulphate) in the ingredients; and by using octadecyl polyoxyethylene ether, alkylphenol polyoxyethylene ether, a penetrant, a leveling agent, fatty alcohol-polyoxyethylene ether, cocoanut fatty acid diethanolamide and a foam stabilizer in the ingredients, the form is promoted to be formed and time for forming the foam can be stabilized. The fog inhibitor prepared by the invention has the advantage of obvious acid fog inhibition effects with a fog inhibition rate of more than 80%, thereby obviously improving work condition of a production workshop and reducing damages to plants, equipment, workers and surrounding conditions of the acid fog.
