Description
Известные способы традлени лент, .тистов и полос не обеспечивают достаточно высоких скоростей обработки и св заны с большим расходом кислоты.The known methods of traversing tapes, brushes and strips do not provide sufficiently high processing speeds and are associated with high acid consumption.
Описываемый способ травлени ноз1}о,т ег довестм скорость тратзлени до 240 м в минуту и обеспечивлст регенералипо большей части кислоты, что снижает ее расход.The described method of etching nos1} o, t it will bring the speed of traction up to 240 m per minute and ensured the regeneration of most of the acid, which reduces its consumption.
Достигаетс это тем, что травление производ т при наложении посто нного тока, подключа протравливаемые издели в качестве анода. Кроме того, процесс ведут J-; нагретом до 99° растворе с невысоким содержанием серной кислоты.This is achieved by the fact that the etching is performed when applying a direct current, connecting the etched products as an anode. In addition, the process is conducted by J-; heated to 99 ° solution with a low content of sulfuric acid.
Травление лент, например латунны.х, осуществл ют в растворе, содержащем от 0,5 до 3,5% серной кислоты, нагретом до 90-99 . Плотность наложенного посто нного тока поддерживают в предела. 300-1000 а на квадратный метр поверхности протравливаемы.х изделий . Скорость движени .тенты через травильную ванну vrr 1 до 4 MJceK, а продолжительность пребывани ленты в травильном растворе от 0,1 до 0,45 сек.Etching tapes, such as brass x, is carried out in a solution containing from 0.5 to 3.5% sulfuric acid, heated to 90-99. The density of the imposed direct current is maintained to the limit. 300-1000 per square meter of surface of etched products. The speed of movement of the tent through the etching bath is vrr 1 to 4 MJceK, and the duration of the stay of the tape in the etching solution is from 0.1 to 0.45 sec.
Описанный способ по;- вол ет одновременно с тра.вленнем осущест}з ть также частичную электрохимическую полировку новер.хности ленч а счет того что плотность тока па мнкровыступах шероховатой поверхности больн1е, чем в других ее местах, вследствие чего эти выступы стравливаютс быстрее. Высока температура травильного раствори способствует очистке ленты от остатков жира и других загр знении. Коэффициент использовани кислоты благодар ее регенерации достигает 0,85-0,9.The described method takes advantage of simultaneously carrying out the partial electrochemical polishing of the renovation of lunch as the current density of the patient on the rough surface of the hospital than in other places, as a result of which the protrusions release more quickly. The high temperature of the pickling solution contributes to cleaning the tape from fat residues and other contaminants. The acid utilization rate due to its regeneration reaches 0.85-0.9.
Предмет изобретени Subject invention
Способ травлени лент, .тистов и полос из цветных металлов и ставов отличающийс тем. что, с целью повышени скорости травлени до 240 метров к минуту и выше, процесс ведут в слаоом растворе серной кислоты при температуре до 99 с на.тожением посто ного тока.The method of etching tapes, brushes and bands from non-ferrous metals and stavos differing in that. that, in order to increase the etching rate to 240 meters per minute and above, the process is carried out in a weak sulfuric acid solution at a temperature of up to 99 s at a constant DC current.
