Description
Известен способ защиты стали от атмосферной коррозии с помощью ингибитора аминного типа,.например дициклогексиламина.There is a method of protecting steel against atmospheric corrosion with an amine-type inhibitor, for example, dicyclohexylamine.
Цель изобретени - одновременна защита стали от коррозии в кислой среде и в растворе хлористого натри .The purpose of the invention is the simultaneous protection of steel against corrosion in an acidic medium and in a solution of sodium chloride.
Дл достижени этой цели в качестве ингибитора примен ют алифатические имины общей формулы RCH NR где R и R- алкил.To achieve this goal, aliphatic imins of the general formula RCH NR are used as the inhibitor, where R and R are alkyl.
В качестве ингибиторов атмосферной коррозии стали мо1Ч г быт1) применены К-бутилидепаллнламин () и N-.этилиденбутиламии (И). В качестве ингибиторов коррозии стали в растворах хлористо о натри и сол ной кислоты эффективны Ы-бутилндеиаллиламии, N-этилиден бутила ми и и К-//з« -бу1ил иденизобутепила .м и II (I I).As an inhibitor of atmospheric corrosion of steel m1ch g byt1), K-butylideplamine () and N-ethylidenebutylamine (I) were used. As inhibitors of corrosion of steel in solutions of sodium chloride and hydrochloric acid, N-ethylbenyl and allylamine, N-ethylidene butyl and and K are effective // z3-bu1il anddenisobuteyl and m (II) I.
Данные исиытаииП, в которых в качестве металла используетс Ст. 3, приведены в таблице .IsytaiP data, in which Art. 3 are shown in the table.
В атмосферных услови х выщеуказанные имииы полностью защищают сталь от коррозии . Образцы после 3-5 мес цев испытаний сохран ют блест щую, непораженную поверхность .In atmospheric conditions, the above mentioned chemicals completely protect steel from corrosion. Samples after 3-5 months of testing retain a shiny, unaffected surface.
В растворе хлористого натри имины уменьщают скорость коррозии стали в 2-4 раза,In a solution of sodium chloride, imines reduce the corrosion rate of steel by 2–4 times,
