Abstract
Description
Изобретение относится к области химии, преимущественно к способам обработки стекла, и может быть использовано в полупроводниковой технологии, стекольной промышленности и т. п. The invention relates to the field of chemistry, mainly to methods for processing glass, and can be used in semiconductor technology, glass industry, etc.
Известен способ химического матирования стекла, включающий предварительную обработку поверхности стекла в водном содовом растворе, матирование в растворе плавиковой кислоты с добавками, нейтрализацию в растворе серной кислоты и промывку водой. A known method of chemical matting of glass, including pre-processing the surface of the glass in an aqueous soda solution, matting in a solution of hydrofluoric acid with additives, neutralization in a solution of sulfuric acid and washing with water.
Недостатками способа являются невысокое качество обработки поверхности стекла. The disadvantages of the method are the low quality of the surface treatment of glass.
Цель изобретения - повышение качества. The purpose of the invention is improving quality.
Способ матирования реализуют следующим образом. The matting method is implemented as follows.
Стеклянные изделия (пластины) предварительно обрабатывают в 10% -ном содовом растворе, затем промываются водой. После этого проводят собственно операцию матирования стекла - обработку его поверхности в смеси плавиковой кислоты и углекислого аммония при соотношении компонентов 1: 2, нейтрализацию в 20% -ной серной кислоте. Завершают цикл обработкой поверхности в 40% -ном содовом растворе и промывкой в воде. Glass products (plates) are pre-treated in a 10% soda solution, then washed with water. After that, the glass matting operation itself is carried out - processing of its surface in a mixture of hydrofluoric acid and ammonium carbonate with a component ratio of 1: 2, neutralization in 20% sulfuric acid. The cycle is completed by surface treatment in a 40% soda solution and washing in water.
Цифровые значения параметров способа определены экспериментально. The digital values of the parameters of the method are determined experimentally.
Положительный эффект от использования изобретения заключается в повышении качества обработки поверхности стекла и результирующем повышении процента годных изделий. The positive effect of the use of the invention is to improve the quality of surface treatment of glass and the resulting increase in the percentage of suitable products.
