Abstract

FIELD: manufacture of sheet glass. SUBSTANCE: the glass comprises (wt % ): 5.2-5.5 aluminium oxide; 3.2-3.8 magnesium oxide; 9.5-10.2 calcium oxide and 0.03-0.05 ferric oxide; and 12-13 at least one of sodium oxide or potassium oxide; 0.8-1.2 zinc arsenide; and silicon oxide, the balance. The translucence 94-96% . EFFECT: improved properties of the glass.

Description

Изобретение относится к технологии силикатов, в частности к составам листового стекла, применяемого, в основном, в строительстве. The invention relates to the technology of silicates, in particular to the compositions of sheet glass, used mainly in construction.

Известно стекло, включающее SiO2, Al2O3, Fe2O3, MgO и другие ингредиенты [1] .Known glass, including SiO 2 , Al 2 O 3 , Fe 2 O 3 , MgO and other ingredients [1].

Известно стекло, включающее следующие ингредиенты, мас. % : SiO2 69,5-83,5; Al2O3 2,5-4,5; CaO 5,7-8,5; MgO 3,0-4,5; Na2O 14,0-16,5; K2O 0,01-1,0; SO3 0,03-0,5; Fe2O3 0,03-0,5 [2] .Known glass, including the following ingredients, wt. %: SiO 2 69.5-83.5; Al 2 O 3 2.5-4.5; CaO 5.7-8.5; MgO 3.0-4.5; Na 2 O 14.0-16.5; K 2 O 0.01-1.0; SO 3 0.03-0.5; Fe 2 O 3 0.03-0.5 [2].

Светопропускание этих стекол составляет 89-92% (при толщине стекла 2 мм). The light transmission of these glasses is 89-92% (with a glass thickness of 2 mm).

Цель изобретения - повышение светопропускания стекла. The purpose of the invention is to increase the light transmission of glass.

Цель достигается тем, что состав стекла, включающий SiO2, Al2O3, CaO, MgO, Fe2O3 по крайней мере один из окислов группы Na2O, K2O, дополнительно содержит Zn3As2, при следующем соотношении ингредиентов, мас. % : Al2O3 5,2-5,5; CaO 9,5-10,2; MgO 3,2-3,8; Fe2O3 0,03-0,05, по крайней мере один оксид из группы Na2O, K2O 12,0-13,0; Zn3As2 0,8-1,2; SiO2 - остальное.The goal is achieved in that the glass composition, including SiO 2 , Al 2 O 3 , CaO, MgO, Fe 2 O 3 , at least one of the oxides of the group Na 2 O, K 2 O, additionally contains Zn 3 As 2 , in the following ratio ingredients, wt. %: Al 2 O 3 5.2-5.5; CaO 9.5-10.2; MgO 3.2-3.8; Fe 2 O 3 0,03-0,05, at least one oxide from the group of Na 2 O, K 2 O 12,0-13,0; Zn 3 As 2 0.8-1.2; SiO 2 - the rest.

В таблице приведены конкретные составы стекла. The table shows the specific compositions of glass.

Светопропускание предложенного стекла (при его толщине 2 мм) составляет следующие величины: для 1 состава - 96% , для 2 состава - 96% , для 3 состава - 94% . The light transmission of the proposed glass (with a thickness of 2 mm) is as follows: for 1 composition - 96%, for 2 composition - 96%, for 3 composition - 94%.
