Изобретение относитс к стекольной промышленности и может быть использовано на заводах, вырабатывающих листовое стекло.The invention relates to the glass industry and can be used in factories producing flat glass.
Известно, что листовое силикатное стекло в процессе хранени v транспортировки при неблагопри тных услови х способно расщелачиватьс , в отдельных случа х с полной потерей прозрачности.It is known that sheet silicate glass during storage v under unfavorable conditions can be alkalized, in some cases with complete loss of transparency.
Известен способ повышени химической устойчивости стекла путем химической модификации его поверхности, включаюший обработку поверхности воздушным потоком, содержашим равновесную смесь тетрафторида кремни , двуокись кремни , фтористого водорода и вод ного пара при 400-700° С. В результате такой обработки ион фтора замещает ионы пздроксила и немостиковых кислородов на поверхности стекла, повыша таким образом ее водоустойчивость до 8 раз 1.There is a method of improving the chemical stability of glass by chemical modification of its surface, which includes surface treatment with an air stream containing an equilibrium mixture of silicon tetrafluoride, silicon dioxide, hydrogen fluoride and water vapor at 400-700 ° C. As a result of this treatment, the fluoride ion replaces pdroxyl ions and non-bridge oxygens on the glass surface, thus increasing its water resistance up to 8 times 1.
Недостатком известного способа вл етс токсичиость фтористых соединений, что существенно ограничивает возможность ихThe disadvantage of this method is the toxicity of fluoride compounds, which significantly limits the possibility of their
практического применени в услови х массовой выработки листового стекла.practical application in conditions of mass production of sheet glass.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ повьпыени химической стойкости стекла путем обработки его поверхности тонкораспыленными спирто-водным раствором хлорида или нитрата алюмини 0,25-3,0%-ной концентрации 2.The closest to the invention to the technical essence and the achieved result is a method of chemical chemical resistance of glass by spraying its surface with sprayed alcohol / water solution of aluminum chloride or nitrate of 0.25-3.0% concentration 2.
Недостатком данного способа вл етс The disadvantage of this method is
to необходимость использовани в качестве растворител этилового спирта, вл ющегос легковоспламен ющейс жидкостью.to the necessity of using as a solvent ethyl alcohol, which is a highly flammable liquid.
Цель изобретени - повыщение безопаснос1S ти процесса.The purpose of the invention is to increase the safety of the process.
Дл достижени поставлениой цели согласно способу повышени химической устойчивости стекла термохимическую обработку поверхности ведут тонкораспыленным 0,1- 5%-ным водным раствором хлорида кальци .In order to achieve the goal according to the method of improving the chemical stability of glass, thermochemical surface treatment is carried out with sprayed 0.1-5% aqueous solution of calcium chloride.
