Description
СWITH
Изобретение относитс к защите от коррозии, в частности к раствору дл химического-пассивировани меди.и ее crolaBOB. The invention relates to protection against corrosion, in particular to a solution for the chemical passivation of copper and its crolaBOB.
Цель изобретени - уменьшение де- 5 фектности и улучшение защитных свойств пассивной пленки, ,, Сущность изобретени заключаетс в том, что дл пассивации меди и ее 1Й1Лавов используют раствор, содержа О щий, мас..%:The purpose of the invention is to reduce the defects and improve the protective properties of the passive film, ,, The essence of the invention is that for the passivation of copper and its 1X1Lavs, a solution containing O ..% is used:
Бензотриазол . 0,2-0,6 Метаналь . 0,05-0,08 Клей животный 0,01-0,03 Вода . Остальное 15 Процесс нанесени пассивной пленки ведут при 40-80°С в течение 0,331ч ..Benzotriazole. 0.2-0.6 Metanal. 0.05-0.08 Animal glue 0.01-0.03 Water. The rest 15 The process of applying a passive film is carried out at 40-80 ° C for 0.331 hours.
Присутствие в растворе кле живот-20 ного и метанал способствует заполHeHiiio пор, имеющих в пленке, и ее уплотнению. гThe presence in the glue solution of the stomach and methane contributes to the filling of the pores in the film and its compaction. g
Раствор сохран етс в течение дли-25 тельного време.ни.The solution is maintained for a long time.
Изобретение иллюстрируетс следующими примерами.The invention is illustrated by the following examples.
Раствор пассивировани готовитс следующим образом. Все компоненты раствор ютс в о.тдельных порци х во .ды и сливаютс в последовательности: бензотриазол, метаналь, клей животный . Объем раствора довод т водой до нужного значени . The passivation solution is prepared as follows. All components are dissolved in approximately portions of water and merged in the sequence: benzotriazole, methane, animal glue. The volume of the solution is adjusted with water to the desired value.
Примеры раствора дл химического пассивировани меди и ее сплавов представлены в табл. 1.Examples of the solution for the chemical passivation of copper and its alloys are presented in Table. one.
Вли ние концентрации компонентов пассивирующего раствора и режима обработки на снижение дефектности пленок представлено в табл. 2.The effect of the concentration of the components of the passivating solution and the mode of treatment on the reduction of the defects of the films is presented in Table 2
Ускоренные коррозионные испытани осуществл лись в двух.коррозионных средах: 3%-ный раствор натри хлористого и влажна ткань. Результаты испытаний представлены в табл.. 3.Accelerated corrosion tests were carried out in two corrosive environments: 3% sodium chloride solution and a damp cloth. The test results are presented in table. 3.
Длительна зксплуатаци раствора показала, что он сохран ет устойчивость по составу и качеству плен2Prolonged operation of the solution showed that it retains stability in composition and quality of the film2.
