Description
Известно применение дл струйного обезжиривани и травлени металлов моющих растворов, содержащих растворы кислот, поверхностно активные вещества, противопенные добавки, защитный коллоид и углеводородный растворитель.It is known to use detergent solutions for jet degreasing and etching of metals, containing acid solutions, surfactants, antifoaming agents, protective colloid, and hydrocarbon solvents.
Однако эти растворы эффективны лишь при повышенных температурах и вл ютс непригодными дл очистки трубопроводов больщой длины.However, these solutions are effective only at elevated temperatures and are unsuitable for cleaning pipelines of greater length.
Применение дл очистки поверхности металлов от продуктов коррозии кислот и их смесей, а также углеводородного растворител - уайт-спирита - известно.The use of cleaning metals from acid corrosion products and their mixtures, as well as a hydrocarbon solvent, white spirit, is known.
Предлагаемый способ получени моющего раствора отличаетс от известных тем, что в качестве поверхностно активного вещества примен ют оксиэтилированный алкилкрезол, благодар чему эффективность моющего средства повыщаетс .The proposed method for the preparation of the washing solution differs from the known ones in that ethoxylated alkylcresol is used as a surfactant, due to which the effectiveness of the detergent is increased.
Моющее средство дл очистки внутренней поверхности нефтепроводов больщой длины и других стальных изделий, получаемое по -предлагаемому способу, состоит из двух несмещивающихс жидкостей - углеводорода и электролита,The detergent for cleaning the inner surface of oil pipelines of a great length and other steel products, obtained by the proposed method, consists of two unmovable liquids - a hydrocarbon and an electrolyte,
В качестве углеводорода предлагаетс использовать уайт-спирит в количестве 300 г на л моющего средства, а в качестве электролита смесь фосфорной и сол ной кислот в концентрации 50 : 50 г/л, неионогенный поверхностно активный препарат ВНИИ НП-58 в концентрации 2 г/л и защитный коллоид карбоксиметилцеллюлоза в концентрации 3 г/л.White spirit is proposed to be used in the amount of 300 g per liter of detergent, and as electrolyte a mixture of phosphoric and hydrochloric acids at a concentration of 50: 50 g / l, a non-ionic surfactant drug VNII NP-58 at a concentration of 2 g / l and protective colloid carboxymethylcellulose at a concentration of 3 g / l.
