Description

Известны фотохромные стекла, содержащие Si02 55-75, ВгОз 0-6, АЬОз 2-12, 12- 18 и С1, F, Ag, Cu2O, CdO в качестве добавок, обусловливающих фотохромность стекла.Known photochromic glass containing SiO 55-75, VgOz 0-6, AOOz 2-12, 12-18 and C1, F, Ag, Cu2O, CdO as additives, contributing to the photochromic glass.

В предложенном изобретении фотохромные стекла дл  иовыщени  их фотохромных свойств содержат компоненты в следующих соотнощени х (в о/о по весу): SiOg 58,5-60; EzOs 19-20; AUOg 9-9,3; NazO 9-11,3; Cl 0,75-1,6; F 0,3-0,7; Ag 0,45; CujO 0,02; CdO 0-0,2.In the proposed invention, the photochromic glasses for analyzing their photochromic properties contain components in the following ratios (in about / o by weight): SiOg 58.5-60; EzOs 19-20; AUOg 9-9.3; NazO 9-11,3; Cl 0.75-1.6; F 0.3-0.7; Ag 0.45; CujO 0.02; CdO 0-0,2.

Варка стекла происходит в обычных услови х . Сразу же после выработки стекло во избежание растрескивани  должно быть помещено в муфель с температурой 450-550 °С, т. е. ири температуре ниже температуры отжига стекла. В результате такого отжига стекло не обладает еще фотохромными свойствами.Glass melting takes place under normal conditions. Immediately after making the glass, in order to avoid cracking, it should be placed in a muffle with a temperature of 450-550 ° C, i.e., and a temperature below the annealing temperature of the glass. As a result of this annealing, the glass does not yet possess photochromic properties.

Дл  получени  фотохромных свойств стекла должны подвергатьс  термообработке в To obtain the photochromic properties of the glass, heat must be subjected to heat treatment in

температурной области 680-650°С Б течение 1 -10 час. Полученные таким образом стекла обладают фотохромпыми свойствами, которые в значительной степени  вл ютс  функцией мощности и спектральной характеристики источника освещени .temperature range 680-650 ° C B for 1 -10 hours. The glasses thus obtained have photochromic properties that are largely a function of the power and spectral characteristics of the source of illumination.

Например, при облучении светом ртутной лампы ДРШ-250 (плотность освещени  на образце 750 вт1м) стекло за врем  30 сек измен ет свою прозрачность от 90 до IQVoПредмет изобретени For example, when a DRSh-250 mercury lamp is irradiated with light (the density of illumination on a sample is 750 W 1 m), the glass changes its transparency from 90 to IQVo in 30 seconds.

Фотохромное стекло на о снове SiOg, , АЬОз, NaO, Cl, F, Ag, Cu.O и CdO, отличающиес  тем, что, с целью повыщени  их фотохромных свойств, они содержат указанные компоненты в следующих соотношени х (в Ь/о по весу): SiOs 58,5-60; -БгОз 19-20; АЬОз 9-9,3; NasO 9-11,3; Cl 0,75-1,6; F 0,3-0,7; Ag 0,45; СшО 0,02, CdO 0-0,2.Photochromic glass on the back of SiOg, AO3, NaO, Cl, F, Ag, Cu.O and CdO, characterized in that, in order to enhance their photochromic properties, they contain these components in the following ratios (in b / o by weight): SiOs 58.5-60; -BGOZ 19-20; ABOZ 9-9,3; NasO 9-11,3; Cl 0.75-1.6; F 0.3-0.7; Ag 0.45; SSO 0.02, CdO 0-0.2.
