Изобретение относитс  к области панесепи  покрытий, в частности свипцовых.The invention relates to the field of panesype coatings, in particular, spray coatings.

Известен способ свипцевани  в электролите, содержащем плюмбит натри , едкий натр и органическую добавку.There is a known method for sweeping in an electrolyte containing sodium plumbite, caustic soda and an organic additive.

Предложенный способ отличаетс  от известного тем, что в электролит в качестве органической добавки ввод т полиэтилепполиамин при определенном содержании компонентов и некотором изменении режима осундествлени  процесса. Это способствует повышению качества покрыти .The proposed method differs from the well-known fact that polyethylene-polyamine is introduced into the electrolyte as an organic additive with a certain content of components and a certain change in the mode of osudalization of the process. This improves the quality of the coating.

Электролит содержит (г/л): Плюмбинат натри  (в лересчете на свинец металлический )25-48 Едкий натр 180-200 Полиэтиленполиамин 0,5-1The electrolyte contains (g / l): sodium plumbinate (in lead curing metal) 25-48 Caustic soda 180-200 Polyethylenepolyamine 0.5-1

Пропуск осуществл ют при температуре 25-90°С и катодной плотности тока 0,5- 8 а/дм. В результате получают мелкокристаллическое , полублест щее лри толщине 15- 100 мк покрытие, прочно сцепленное с основой .The pass is carried out at a temperature of 25-90 ° C and a cathode current density of 0.5-8 A / dm. The result is a crystalline, semi-glossy coating with a thickness of 15-100 microns, firmly adhering to the substrate.

Нанесение свинцового покрыти  предложенным способом производ т .при подготовке медных и латунных изделий под пайку. Покрытие сохран ет свою способность к найке в течение длительного времени.The application of a lead coating by the proposed method is carried out when preparing copper and brass products for brazing. The coating retains its ability to nike for a long time.

Электролит дл  свинцевани  приготавливают следующим образом.Lead electrolyte is prepared as follows.

Получают раствор плюмбита свинца путем растворени  в растворе едкого натра уксуснокислого свинца или гидроокиси свинца или путем анодного растворени  металлического свинца в растворе едкого натра. Затем в 100 мл 10%-ного раствора едкого натра раствор ют 5 г полиэтиленполиамина, полученныйA solution of lead plumbite is obtained by dissolving lead acetate acetate or lead hydroxide in caustic soda solution or by anodic dissolving metallic lead in caustic soda solution. Then, in 100 ml of a 10% aqueous solution of sodium hydroxide, 5 g of polyethylene polyamine is dissolved, obtained

раствор кип т т в течение 15 мин и после охлаждени  довод т объем раствора до 100 мл. Полученный раствор полиэтиленполиамина ввод т в раствор плюмбита натри  в количестве 0,5-1 г/л (в пересчете на полнэтиленполиамин ).the solution is boiled for 15 minutes and, after cooling, the volume of the solution is adjusted to 100 ml. The resulting solution of polyethylene polyamine is introduced into a solution of sodium plumbbit in the amount of 0.5-1 g / l (in terms of polyethylene polyamine).
