Description
Изобретение относитс к составам глушеных стекол, предназначенных дл изготовлени отделочных строительных материалов, и может быть широко использовано в стекольной технологии . Известно глушеное стекло i, включающее SiO СаО, МдО, АС205 и в следующих количествах, вёс.%: SiO2 65-80 СаО 15-30, МдО 0,5-3,0, АвуОз 1-2,5, 0,52 ,0. Наиболее близким к изобретению по технической сущности и достигаемо му рейультату вл етс глушенсе стекло 2} следующего состава,вес.% Si02 50-63, СаО 22-33, МдО 13-21, 1-30, Nb,2O 0,5-2,0.Это стекло глушитс при выработке, из него.можн делать непрозрачные белые и окрашенные строительные материалы, К недостаткам этих стекол относ тс высокие температуры варки ( 1530-1550 с) и выработки (13001350°С ), а также повышенные температуры кристаллизации (1000-1100°С), Цель изобретени - понижение температуры варки и выработки стекла . достигаетс тем, что стекло щее SiO2, СаО, Na2O, держит указанные компоненты ющих количествах, масс.%: SiO2 43 29-50,92 СаО 35,68-41,96 0,1-4,00 2,74-3,99 МдО 4,37-13,04 ретные составы стекол приветабл . 1. Таблица,The invention relates to a glass jerked composition for the manufacture of finishing building materials, and can be widely used in glass technology. Known jammed glass i, including SiO CaO, MDO, AC205 and in the following amounts, weight.%: SiO2 65-80 CaO 15-30, MDO 0.5-3.0, AvuOz 1-2.5, 0.52, 0 The closest to the invention according to the technical nature and achievable reyatudu is glass 2} of the following composition, wt.% Si02 50-63, CaO 22-33, MgO 13-21, 1-30, Nb, 2O 0.5-2 , 0. This glass is jammed when working out, it is possible to make opaque white and painted building materials from it. The disadvantages of these glasses include high temperatures of cooking (1530-1550 s) and production (13001350 ° C), as well as elevated crystallization temperatures ( 1000-1100 ° C), The purpose of the invention is to lower the temperature of melting and glass production. is achieved by the fact that the glass SiO2, CaO, Na2O, keeps the indicated component quantities, wt.%: SiO2 43 29-50.92 CaO 35.68-41.96 0.1-4.00 2.74-3, 99 MDO 4.37–13.04 retina glass compositions hiabl. 1.
