Description
Изобретение относитс к составам стекол , которые могут быть использованы дл производства стеклоизделий различного назначени , в частности светотехнических изделий .The invention relates to glass compositions that can be used for the production of glass products for various purposes, in particular lighting products.
Цель изобретени - снижение температуры варки и повышение светопропускани в видимой области.The purpose of the invention is to reduce the cooking temperature and increase light transmission in the visible region.
Конкретные составы стекол и их свойства приведены в таблице.Specific compositions of glasses and their properties are shown in the table.
Дл синтеза стекол используют следующие сырьевые материалы:песок кварцевый, гидроксид алюмини , доломит, мел, сода кальцинированна , барий углекислый, сульфат натри , соль поваренна , поташ.The following raw materials are used to synthesize glasses: silica sand, aluminum hydroxide, dolomite, chalk, soda ash, barium carbonate, sodium sulfate, salt, potash.
Стекло вар т в стекловаренных печах любой конструкции при 1440-1450°С.Glass var in glass furnaces of any design at 1440-1450 ° C.
Благодар йптимальному соотношению оксидов стекло обладает хорошими варочными свойствами и повышенным светопро- пусканием.Due to the optimum ratio of oxides, glass has good cooking properties and high light transmission.
Стекло может быть использовано дл производства светотехнических изделий, а также в строительстве.Glass can be used for the production of lighting products, as well as in construction.
