CORROSION INHIBITING COMPOSITION FOR CHEMICAL PURIFICATION OF POWER EQUIPMENT

摘要

A corrosion inhibiting composition for chemical purification of power equipment, which has increased properties, in particular corrosion protective effect, etching effectiveness, hydrogenation and low cyclic hydrogen fatigue, which contains as a base 6 % HCl with 0.5 g/l oxalate acid or 5 g/l LDA (low-molecular dicarboxylic acids) with the addition of synergistic protective composition (SPC) of nitrogen-containing wastes of ammonia or caprolactam production in the quantity of 5-10 g/l with S-containing synergist, derivative of 1,2-mercaptobenzoimidazole in the quantity of 0.2-0.4 g/l.
