Abstract

The invention relates to a cleaning treating solution for stainless steel and iron member composite boards. The cleaning treating solution comprises following components by weight: 18%-20% of a polyoxyethylene alkyl ether, 2%-3% of an alkylphenol ethoxylate, 8%-9% of citric acid, 6%-7% of a corrosion inhibitor, 8%-10% of hexamethylenetetramine, 5%-6% of a metal complexing agent, 1%-2% of hydrochloric acid, 0.5%-1% of hydrofluoric acid, 1.5%-3% of sodium molybdate and 40%-50% of water. The cleaning treating solution is capable of cleaning metal surface impurities (such as oil and grease, rust, sinter, scale oxide and dirt), adsorbing on the cleaned work piece and forming a passivating film, thus playing a function of anticorrosion, prolonging the service lifetime of the work piece, and achieving cleaning, corrosion preventing and passivating effects all at once.

Description

technical field [0001] The invention relates to the field of metal cleaning, in particular to a cleaning solution for stainless steel and iron composite plates. Background technique [0002] At present, acid and alkaline cleaning agents are still widely used in industrial production to clean stainless steel plates and iron plates. During the cleaning process, stainless steel and iron steel are often caused great harm, and it is easy to cause pitting corrosion and crevice corrosion of stainless steel, and may Cause hydrogen embrittlement, chlorine embrittlement and alkali embrittlement of steel, and accelerate the cracking and damage of stainless steel and iron steel. [0003] In order to make the material anti-corrosion, it is necessary to carry out anti-corrosion, passivation and other processes after chemical cleaning, so as to achieve the effect of metal surface cleaning treatment. Contents of the invention [0004] The purpose of the present invention is to overcome t...
