Description
3 Услови процесса аналогичны примеру I. Никелевое покрытие толщиной 30 мк также удал етс с основы в течение 1 мин. Предложенный состав электролита повышает качество сн ти различных гальванических покрытий, не вызыва при этом растравливани стальной основы. -Предмет изобретени Электролит дл сн ти гальванических покрытий , содержащий нитрат-ионы и триэтаноламин , отличающийс тем, что, с це4 лью повышени качества сн ти покрытий со стальной основы, в электролит введено соединение , ускор ющее растворение покрыти , выбранное из группы, содержащей хлорид аммони , роданид аммони и фенол, и буферирующа добавка, выбранна из группы, содержащей уксусную, лимонную, молочную и щавелевую кислоты, при следующем содержании компонентов, г/л: Нитрат аммони 5-100 Триэтаноламин50-400 Соединение, ускор ющее растворение покрыти 0,5-10 Буферирующа добавка До рН 5-7.3 The process conditions are similar to example I. A 30 micron thick nickel plating is also removed from the substrate within 1 minute. The proposed electrolyte composition improves the quality of the removal of various electroplating coatings without causing etching of the steel substrate. DETAILED DESCRIPTION OF THE INVENTION Electrolyte for removing electroplated coatings containing nitrate ions and triethanolamine, characterized in that, in order to improve the quality of removal of coatings from a steel base, a compound that accelerates the dissolution of the coating selected from the group containing chloride is introduced into the electrolyte ammonium, ammonium rhodanide and phenol, and a buffering additive selected from the group consisting of acetic, citric, lactic and oxalic acids, with the following content of components, g / l: ammonium nitrate 5-100 triethanolamine 50-400 Compound, accelerating its dissolution is 0.5–10–10 buffering additive to pH 5–7.
