INHIBITOR OF CORROSION-MECHANICAL DESTRUCTION OF LOW-ALLOY STEEL

摘要

FIELD: metal protection against corrosion. SUBSTANCE: inhibitor has, wt.-% dioxane alcohol 1 (4-methyl-4-hydroxymethyl-1,3-dioxane) 10-15; dioxane alcohol 2 (4,4-dimethyl-5-hydroxymethyl-1,3-dioxane) 10-15; high-boiling products 10-15; 4,4-dimethyl-1,3-dioxane 3-5; dioxane alcohol 1 allyl ester 55-65. Increased protective effect against hydrogen sulfide cracking and corrosion fatigue is obtained by additional addition of dioxane alcohol 1 allyl ester. EFFECT: increased effectiveness of protection against corrosion. 3 tbl
