Description

Состав готов т следующим образом. Компоненты взвешивают з определенных количествах и смешивают в агатовой ступке. Полученную шихту засыпают в корундовые тигли и загружают вThe composition is prepared as follows. The components are weighed in certain quantities and mixed in an agate mortar. The resulting mixture is poured into corundum crucibles and loaded into

силитовую печь. При осуществл  ют варку с вьадержкой 1ч.silicon stove. When boiling is carried out with a boil of 1 hour.

Полученное стекло и изготовленные из него микрошарики обладают свойствами , приведенными в табл. 2.The resulting glass and microbeads made from it have the properties shown in table. 2

Claims (1)

Положительным эффектом изобретеНИН  вл етс  то, что уменьшение содержани  в составе оксида по сравнению с прототипом снижает его себестоимость, наличие двух щелочноземельных оксидов улучшает провар и осветление стекломассы во врем  варки , т.е. предлагаемое стекло  вл етс более технологичным и низкотемпераггурным . Кроме того, предлагаемый состав стекла позвол ет получить синее стекло, необходимое дл  образовани  микрошариков, которые в данном случае обладают удовлетворительными физическими свойствами. Формула изобретени  Стекло дл  изготовлени  микрошари ков светоотражаю1цих дорожно-сигнальных знаков, включающее РЬО, Si 02 8203, CdO, отличающеес  тем, что, с целью снижени  температуры варки, оно дополнительно содержит ВаО, SrO, при следующем соотношении ингредиентов, мас.%; РЬОl 0,,0 8,0-20,0 5,0-15,0 8,0-12,0 8,0-12,0 8,0-12,0 1,0-3,0 Источники информации, прин тые во внимание при экспертизе 1.Авторское свидетельство СССР 804584, кл. С 03 С 3/10, 1979. 2,Авторское свидетельство СССР № 608774, кл. С 03 С 3/10, 1976 (.прототип).The positive effect of the invention is that reducing the content of the oxide in comparison with the prototype reduces its cost, the presence of two alkaline earth oxides improves the penetration and clarification of the glass melt during cooking, i.e. The offered glass is more technological and low-temperature. In addition, the proposed glass composition produces blue glass required for the formation of microbeads, which in this case have satisfactory physical properties. The invention The glass for the manufacture of microbeads of light-reflecting traffic signs, including PHO, Si 02 8203, CdO, characterized in that, in order to reduce the cooking temperature, it additionally contains BaO, SrO, in the following ratio of ingredients, wt.%; PALL 0, 0 8.0-20.0 5.0-15.0 8.0-12.0 8.0-12.0 8.0-12.0 1.0-3.0 Sources of information, taken into account during the examination 1.
