Description
Изобретение относитс к производству кварцевого стекла и изделий на основе кремнезема и может быть использовано дл очистки поверхности изделий из кварцевого стекла от посторонних примесей.The invention relates to the production of quartz glass and products based on silica and can be used to clean the surface of quartz glass products from impurities.
Примеси внедр ютс в поверхностные слои стекла при высоких температурах , необходимых дл плавлени и формовани кварцевого стекла (1500-2000°с) за счет диффузии из окружающих сопутствующих материалов , примен емых в производстве кварцевого стекла. К таким материалам относ тс : графит, огнеупоры, молибден, вольфрам, газы-теплоносители и т.п. Удал ть посторонние примеси с поверхности кварцевого стекла путем химического травлени необходимо дл качественного проведени процессов спекани , формовани и при кварцедувных работах.Impurities are introduced into the surface layers of glass at the high temperatures required for melting and molding quartz glass (1500-2000 ° C) due to diffusion from the surrounding accompanying materials used in the production of quartz glass. Such materials include: graphite, refractories, molybdenum, tungsten, heat-transfer gases, etc. Removing impurities from the surface of silica glass by chemical etching is necessary for high-quality sintering, molding and quartz-forming processes.

Цель изобретени - повьшение скорости процесса травлени и его удешевление.The purpose of the invention is to increase the speed of the etching process and reduce its cost.
Составы растворов и скорость травлени образцов приведены в таблице .The compositions of the solutions and the etching rate of the samples are given in the table.
По данным, приведенным в таблице , видно, что скорость травлени кварцевого стекла в 1,2-1,5 раза вьше, чем у известного раствора би- фторида аммони .According to the data in the table, it can be seen that the etching rate of quartz glass is 1.2–1.5 times higher than that of the known solution of ammonium bifluoride.
Повьшение скорости травлени приводит к сокращению длительности процесса, что дает экономию как трудовых, так и материальных затрат на его проведение, кроме того, стоимость известного раствора по сравнению с предлагаемым выше.The increase in the rate of etching leads to a reduction in the duration of the process, which gives savings both labor and material costs for its implementation, in addition, the cost of a known solution compared with the proposed above.
Использование предлагаемого раст- вора позвол ет улучшить услови The use of the proposed solution allows to improve the conditions
труда, избежать загр знени окружающей средь и т.п.; поскольку не дает токсичных испарений.labor, avoid environmental pollution, etc .; because it does not give toxic fumes.
