Description
Изобретение относитс к составам глушенных стекол, предназначенных дл изготовлени отдельных строительных материалов, и может быть широко использовано в стекольной технологии.The invention relates to wilted glass compositions intended for the manufacture of individual building materials, and can be widely used in glass technology.
Цель изобретени - повышение коэффициента линейного термического расширени .The purpose of the invention is to increase the coefficient of linear thermal expansion.
Конкретные составы и свойства стекол приведены в таблице.Specific compositions and properties of glasses are given in the table.
В состав стекла могут входить красители СаО, Мп02, СиО, Сг20з, РеаОз в количестве 0,3-2,0% по массе дл расширени цветовой гаммы материала и не вли ющие на достижение поставленной цели.Glass dyes may contain CaO, MnO2, CuO, Cr20z, ReaOz dyes in an amount of 0.3-2.0% by mass to expand the color gamut of the material and do not affect the achievement of the goal.
Стекло вар т в пр моточной ванной печи при 1360-1380°С. Температура выработки 1100-1150°С.The glass is heated in a continuous bath at 1360-1380 ° C. The temperature of production 1100-1150 ° C.
Дл варки стекол используют сырьевые материалы: песок, соду, поташ, доломит , каолин, окись цинка и крас щие добавки, которые ввод т в виде индивидуальных солей, окислов, отходов.Raw materials are used to cook glasses: sand, soda, potash, dolomite, kaolin, zinc oxide and coloring additives, which are introduced in the form of individual salts, oxides, waste.
Указанный состав стекла за счет своих технологических и физико-химическихThe specified glass composition due to its technological and physico-chemical
свойств позвол ет получать стеклокристал- лические глушеные плиты повторной термообработке .properties allows to obtain glass-ceramic muffled plates by repeated heat treatment.
За счет присутстви СаО, МдО при соотношении 1,4:1 стекло становитс заглушающим при повторной термообработке. Это дает возможность заменить глушители фтора и фосфора при производстве стеклокри- сталлических плит, которые вл ютс дефицитным, дорогосто щими и токсичными . Оптимальное значение К20 и Naf) улучшает химическую устойчивость стекла, а Ре20з оказывает вли ние на снижение температуры варки и выработки.Due to the presence of CaO, MDO at a ratio of 1.4: 1, glass becomes muffled when re-heat treated. This makes it possible to replace the mufflers for fluorine and phosphorus in the production of glass-crystalline plates, which are scarce, expensive and toxic. The optimum value of K20 and Naf) improves the chemical resistance of glass, and Fe20z has an effect on lowering the temperature of cooking and generation.
