FIELD: inhibitors for metals corrosion protection in hydrochloric acid and sulfuric acids.
SUBSTANCE: the invention is pertaining to the field of protection of metals from corrosion in hydrochloric acid and sulfuric acids with the help of inhibitors and may be used at etching treatment of metals in hydrochloric acid and sulfuric acids, and also for acid cleanout of equipment. The inhibitor contains(in mass %): n- iodobensal-2-amino-5- nitrophenol - 20.9-29.2; 5- bromine-3-fluorine-buhyl-6-methyluracil - 33.5-42.9; urotropin - 27.5-45.6. Utilization of the inhibitor allows to increase a degree of protection of steel, titanium and chromium against corrosion and also to reduce hydrogenation of steel.
EFFECT: the invention allows to improve protection of steel, titanium and chromium against corrosion, to reduce hydrogenation of steel.
