Description
Известны способы сн ти ржавчины с деталей из черных металлов при помощи их травлени неорганическими кислотами или виннокаменной кислотой. Недостатком травлени деталей в неорганических кислотах вл етс то, что выдел ющийс при этом водород поглощаетс поверхностным слоем стали, который становитс хрупким.Methods are known for removing rust from ferrous metal parts by etching them with inorganic acids or tartaric acid. The disadvantage of etching parts in inorganic acids is that the released hydrogen is absorbed by the surface layer of steel, which becomes brittle.
в описываемом способе, в отличие от известных, дл сн ти ржавчины используетс водный раствор хлористого нинка в сочетании с виннокаменной кислотой. При сн тии ржавчины этим раствором он не нарушает основного металла, а снимает только окислы железа.In the described method, unlike the known ones, an aqueous solution of Nink chloride in combination with tartaric acid is used to remove rust. When removing this rust with this solution, it does not break the base metal, but only removes iron oxides.
Детали, с которых нужно сн ть ржавчину погружают в водный раствор следующего состава: 100 г/л технического хлористогоParts from which rust must be removed are immersed in an aqueous solution of the following composition: 100 g / l technical chloride
цинкй :. добавкой в качестве катализатора 2,5 г1л виннокаменной кислоты. Продолжительность обработки в растворе не менее суток. Хлористый цинк и виннокаменна кислота вступа 0:Т во взаимодейст вне с окислами железа, образу комплекс галогенидов, не затрагива при этом основного металла.zinc: addition of 2.5 g1l of tartaric acid as a catalyst. Duration of treatment in the solution for at least a day. Zinc chloride and tartaric acid entering 0: T interact with iron oxides, forming a complex of halides, without affecting the base metal.
Способ может примен тьс дл сн ти коррозии с деталей сложной конфигурации, с тонкостенных деталей, с измерительных инструментов и т. п.The method can be applied to remove corrosion from parts of complex configuration, from thin-walled parts, from measuring instruments, etc.
Предмет изобретени Subject invention
Способ сн ти ржавчины с черных металлов, отличающийс тем, что обработку металлов производ т в водном растворе, состо нием из 100 хлористого цинка и 2,5 г1л виннокаменной кислоты.The method of removing rust from ferrous metals, characterized in that the processing of metals is carried out in an aqueous solution, the state of 100 zinc chloride and 2.5 g of tartaric acid.
