Description
Известные способы травлени поверхности хрома или пленки хрома, нанесенной на нодложку, например, из стекла или кварца дл получени изображений шкал, рисунков и т. п. не обеспечивают их долговечности .Known methods of etching the surface of chromium or a film of chromium deposited on a backing, such as glass or quartz, to obtain images of scales, patterns, etc., do not ensure their durability.
Описываемый способ позвол ет получать прочные изображени , не порт щиес в обычных услови х, стойкие к щелочам и кислотам без покрыти их защитным слоем лака.The described method allows to obtain durable images that are not importable under normal conditions, resistant to alkalis and acids without being coated with a protective lacquer layer.
Способ состоит в том, что хромова пленка наноситс распылением частиц металла в вакууме на стекло, кварц, а также на другие стойкие подложки и травитс по рисункам, выгравированным на кислотоупорной основе, или по фотографическим изображени м на хромированном слое коллоида или смолы раствором марганцовокислого кали с последующим осветлением или сол ной кислоты с припудриванием опилками металла (например, цинка или алюмини ), выдел ющего при травлении водород.The method consists in that the chromium film is applied by spraying metal particles in vacuum onto glass, quartz, as well as other resistant substrates and etched in drawings engraved on an acid-resistant base, or in photographic images on a chromium colloid or resin layer with potassium permanganate solution subsequent clarification with hydrochloric acid and dusting metal filings (for example, zinc or aluminum), which liberates hydrogen during etching.
В последнем случае травление можно производить в контакте сло с металлической поверхностью, например, пластиной из листа цинка или алюмини .In the latter case, the etching can be carried out in contact of the layer with a metal surface, for example, a plate made from a sheet of zinc or aluminum.
Предмет изобретени Subject invention
Способ травлени поверхности хрома или пленки хрома, нанесенной на стойкую подложку, например, стекло, кварц, с целью получени изображений щкал, рисунков и т. д., от л и ч а ю щ и и с тем, что в качестве трав щей жидкости примен ют раствор марганцовокислого кали с последующей обработкой протравленной поверхности просветл ющей жидкостью, например, раствором гипосульфита.The method of etching the surface of chromium or a chromium film deposited on a resistant substrate, for example glass, quartz, in order to obtain images of shkal, drawings and so on, from l and h as well as A solution of potassium permanganate is used, followed by treating the etched surface with bleaching liquid, for example, hyposulfite solution.
2. Водоизменение способа травлени по п. 1, отличающеес тем, что в качестве трав щей жидкости примен ют сол ную кислоту совместно с металлами, способствующими выделению водорода, например , цинком или алюминием, в виде порошка или пластины, контактируемыми с протравливаемой поверхностью.2. Water treatment etching method according to claim 1, characterized in that hydrochloric acid is used as a pickling fluid together with metals that promote hydrogen evolution, for example, zinc or aluminum, in the form of a powder or a plate in contact with the surface being etched.
