Description

Изобретение относится к составам травильных растворов, которые могут быть использованы для обработки стекол.The invention relates to compositions of etching solutions that can be used for processing glasses.

Известен травильный раствор, содержащий, мас.%: фтористоводородная кислота 50,0-60,0; азотная кислота 20,0-30,0; полиакриламид 1,0-5,0; вода - остальное [1]. Скорость травления стекла таким раствором составляет 0,5-0,69 мкм/мин.Known etching solution containing, wt.%: Hydrofluoric acid 50.0-60.0; nitric acid 20.0-30.0; polyacrylamide 1.0-5.0; water - the rest [1]. The etching rate of glass with such a solution is 0.5-0.69 μm / min.

Задача изобретения состоит в увеличении скорости процесса травления стекла.The objective of the invention is to increase the speed of the etching process of glass.

Технический результат достигается тем, что травильный раствор для обработки стекла, содержащий фтористоводородную кислоту, азотную кислоту, полиакриламид, воду, дополнительно содержит соляную кислоту и глицерин при следующем соотношении компонентов, мас.%: фтористоводородная кислота 50,0-60,0; азотная кислота 20,0-30,0; полиакриламид 2,0-3,0; соляная кислота 9,0-11,0; глицерин 1,0-2,0; вода 5,0-7,0.The technical result is achieved by the fact that the etching solution for processing glass containing hydrofluoric acid, nitric acid, polyacrylamide, water, additionally contains hydrochloric acid and glycerin in the following ratio, wt.%: Hydrofluoric acid 50.0-60.0; nitric acid 20.0-30.0; polyacrylamide 2.0-3.0; hydrochloric acid 9.0-11.0; glycerol 1.0-2.0; water 5.0-7.0.

В таблице приведены составы травильного раствора для обработки стекла.The table shows the compositions of the etching solution for processing glass.
