Problems solved by technology

But this method can only be applied to small-scale industrial production, as in its embodiment, the amount of thermal melting of glass has only 180 tons per day, which can be produced on a small float glass production line; the melting temperature of glass in the melting furnace is high, and in the melting process The melting process in the melting furnace is difficult to control. If the reducing atmosphere in the melting

Embodiment 1

[0076] On the 460-ton float glass production line, the components in the glass frit in the kiln head bin of the melting furnace include (percentage by weight): SiO 2 66.2; Na 2 O 13.3; K 2 O 1.1; CaO 6.6; Al 2 o 3 1.0; C 3.8; TiO 2 2.0; CeO 2 4.9; Fe 2 o 3 0.1; ZnO 0.18; Eu 2 o 3 0.29; Dy 2 o 3 0.26; BaO 0.1; PbO 0.11. After feeding, after melting, forming, annealing, cutting and other processes, crystal yellow glass is produced, with a crystal clear appearance and a visible light transmittance of 83.5%.

Embodiment 2

[0078] Change the content of each component in the glass frit described in embodiment 1, particularly the composition and content thereof of coloring agent; Each component and its content in the glass frit of embodiment 2 are (percentage by weight): SiO 2 63.5; Na 2 O 13.2; K 2 O 1.8; CaO 7.1; Al 2 o 3 1.2; C 7.5; TiO 2 1.5; CeO 2 3.5; Fe 2 o 3 0.14; ZnO 0.15; SnI 2 0.09;V 2 o 5 0.22; 2 o 3 0.07. The process is the same as in Example 1; a slightly lighter crystal yellow glass than that in Example 1 is produced, and the visible light transmittance is 81.9%.

Embodiment 3

[0080] Change each component content in the glass frit described in embodiment 1 and embodiment 2, especially the composition and content thereof of coloring agent; Each component and its content in the glass frit of embodiment 3 are (weight percent) SiO 2 69.5; Na 2 O 12.1; K 2 O 0.8; CaO 6.2; Al 2 o 3 0.66; C 8.2; TiO 2 0.8; CeO 2 1.1; Fe 2 o 3 0.08; ZnO 0.06; BaO 0.12; MnO 2 0.21; 2 o 3 0.13. The process used is the same as in Example 1; the color of the produced crystal yellow glass is lighter than that of Example 2, and the visible light transmittance is 80.6%.

Description

【Technical field】 [0001] The invention relates to a radiation-proof crystal yellow glass composition, which belongs to the field of glass. 【Background technique】 [0002] The earliest glass product was colorless transparent glass; as people's requirements for decorative effects became higher and higher, people have been trying various methods to add color to glass, such as adding various colorants or using coating methods. Change the color of the glass. More and more colored glass products are emerging on the market, such as gray series glass, green series glass, blue series glass and so on. Colored glass can be produced by adding commonly used colorants, but it is generally gray, brown, green, blue and other colors, and yellow series, especially crystal yellow series of colored glass is rarely found. And crystal yellow is a color that people especially like. Therefore, it is imminent to develop a crystal yellow glass with a bright effect or a golden effect. [0003] Yel...
