Description

Изобретение относится к составам легкоплавких опаловых стекол и может быть использовано для изготовления светотехнических изделий различного назначения. The invention relates to compositions of low-melting opal glasses and can be used for the manufacture of lighting products for various purposes.

Известно стекло [1] содержащее, мас. SiO2 67-71 CaO + MgO 12-14,5 Al2O3 4-9 Na2O 8-12,5 F' 0,3-1,2.Known glass [1] containing, by weight. SiO 2 67-71 CaO + MgO 12-14.5 Al 2 O 3 4-9 Na 2 O 8-12.5 F '0.3-1.2.

Наиболее близким является легкоплавкое стекло [2] содержащее, мас. SiO2 60,0-85,0 Al2O3 0,5-10,0 CaO 0,3-20,0 R2O 2,0-25,0 MgO 0-10,0 PbO 0-10,0 ZnO 0-10,0 BaO 0,3-20 F' 0-3,0 AO3 0,1-3,0 B2O3 0-5,0 Cl' 0,1-3,5 SrO 0-10,0 As2O3 0-1,0 Sb2O3 0-0,1 и может содержать по крайней мере один из оксидов: Cr2O3, CeO2, CuO, Mn2O3, NiO, TiO2, CoO, Za2O3 в количестве 0,01-5%
Указанный состав не может быть использован для получения светотехнических изделий сложной конфигурации, изделий специального назначения ввиду низкой отражательной способности, малой величины белизны.The closest is fusible glass [2] containing, by weight. SiO 2 60.0-85.0 Al 2 O 3 0.5-10.0 CaO 0.3-20.0 R 2 O 2.0-25.0 MgO 0-10.0 PbO 0-10.0 ZnO 0-10.0 BaO 0.3-20 F '0-3.0 AO 3 0.1-3.0 B 2 O 3 0-5.0 Cl' 0.1-3.5 SrO 0-10 , 0 As 2 O 3 0-1.0 Sb 2 O 3 0-0.1 and may contain at least one of the oxides: Cr 2 O 3 , CeO 2 , CuO, Mn 2 O 3 , NiO, TiO 2 , CoO, Za 2 O 3 in an amount of 0.01-5%
The specified composition cannot be used to obtain lighting products of complex configuration, products for special purposes due to the low reflectivity, low brightness.

Цель изобретения увеличение белизны стекла. Указанная цель достигается тем, что стекло содержит, мас. SiO 64-72,0 Al2O3 2,5-7,5 CaO 3,5-6,0 Na2O 14,5-19,0 F' 3,5-6,5
Температура варки стекла составляет 1350-1420оС. Выработку можно осуществлять на прессовыдувных автоматах или способом ручного формования.The purpose of the invention is the increase in whiteness of glass. This goal is achieved in that the glass contains, by weight. SiO 64-72.0 Al 2 O 3 2.5-7.5 CaO 3.5-6.0 Na 2 O 14.5-19.0 F '3.5-6.5
The temperature of glass melting is 1350-1420 about C. The production can be carried out on press-blowing machines or by manual molding.

Увеличение белизны стекла позволяет получать светотехнические изделия различной конфигурации не только в виде бытовых светильников, но и в виде изделий для медицинских и специальных целей. Increasing the whiteness of glass allows you to get lighting products of various configurations not only in the form of household fixtures, but also in the form of products for medical and special purposes.

Конкретные примеры выполнения изобретения представлены в табл. 1 и 2. Specific examples of the invention are presented in table. 1 and 2.
