Description
Известны иигибиторы коррозии металлов, которыми вл ютс органические вещества, такие, как альдегиды, амины, тиомочевииа и другие.Corrosion inhibitors of metals, which are organic substances such as aldehydes, amines, thioureas, and others, are known.
Предлагаетс дл защиты от коррозии углеродистой стали в воде и водных растворах кислот примен ть в качестве ингибитора сланцевый деэмульгатор, изготовл емый по СТУ-27-1 Куйбышевским СНХ.It is proposed to use shale demulsifier manufactured according to STU-27-1 by the Kuibyshev CHX as an inhibitor against corrosion of carbon steel in water and aqueous solutions of acids.
Действие ингибитора было испытано авторами в водных растворах серной кислоты и неорганических солей, в сточной воде сланцеперерабатывающего комбината при рН от 2,0 до 7,4.The effect of the inhibitor was tested by the authors in aqueous solutions of sulfuric acid and inorganic salts, in the waste water of the oil shale processing plant at a pH of 2.0 to 7.4.
Введение 1 -10 г/л сланцевого деэмульгатора уменьшает скорость коррозии углеродистой стали в 2-15 раз.Introduction of 1-10 g / l of shale demulsifier reduces the corrosion rate of carbon steel by 2-15 times.
Предмет изобретени Subject invention
Способ защиты металлов от коррозии в воде и водных растворах кислот с помощью ингибитора , отличающийс тем, что, с целью защиты металлов в воде и водных растворах кислот, в качестве ингибитора добавл ют сланцевый деэмЗльгатор, получаемый известным методом.A method of protecting metals from corrosion in water and aqueous solutions of acids with an inhibitor, characterized in that, in order to protect metals in water and aqueous solutions of acids, a shale demulsifier obtained by a known method is added as an inhibitor.
