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, alkylphenolpolyoxyethylene 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.

Description

technical field [0001] The invention belongs to the field of fog inhibitors, in particular to a pickling corrosion inhibitor and fog inhibitor. Background technique [0002] With the development of metallurgical technology, the trend of replacing sulfuric acid pickling with hydrochloric acid pickling in the pickling process is becoming more and more obvious, which makes the research on hydrochloric acid corrosion and fog inhibitors more and more in-depth. Existing products on the market have large additions, crystallization, and unstable foam layer formation, which are not suitable for industrial production requirements. [0003] According to the search, the following patents related to fog inhibitors are found, wherein CN101851761A discloses a sulfuric acid pickling corrosion inhibitor and fog inhibitor, which includes an inhibitor, a complexing agent and a wetting agent, and the weight percentages of each component are as follows: a, inhibitor : Di-o-toluenethiourea 6%-10...
