Problems solved by technology

The surface of the waste glass is polluted by inorganic substances such as polyvalent metals and metal oxides such as thin film transistors (TFT) or transparent conductive films (ITO), and organic substances such as color filters and polarizing films, so that not only the overall waste glass The color changes, and depending on the situation, even the composition of the glass changes, so it cannot be reused as a raw material for liquid crystal display glass substrates in reality, and can only be landfilled or used as a raw material for low-cost cement

Embodiment 1～15

[0050] Weigh and mix various raw materials according to the proportions of the ingredients in Table 2, Table 3, and Table 4 below, so that the weight of the total ingredients is 500g, and then use a 600cc platinum crucible to melt at 1550°C for 3 hours before using A platinum stirrer homogenizes the molten glass, then forms it into a plate shape, keeps it at 700°C for 1 hour in an electric furnace, and then slowly cools it to room temperature to produce glass.

[0051] For each ingredient composition, the composition of the glass is shown in the middle of Table 2, Table 3, and Table 4, and the measurement results of the high-temperature physical properties of the glass are shown at the bottom of Table 2, Table 3, and Table 4. Among high temperature physical properties, T m Indicates the temperature corresponding to 100poise, T w Indicates the molding temperature corresponding to 1000poise, T liq Indicates the highest temperature at which crystallization occurs, that is, the ...

Abstract

The present invention relates to the borosilicate system filament glass batch composition having the mixture between the glass frit generated in the commercial production process of the glass for the thin-film transistor liquid crystal display (TFT-LCD) and the waste glass generated in the commercial production process of the liquid crystal display panel as the raw material of the borosilicate system filament glass, more specifically, provides the batch composition of the borosilicate system filament glass which includes the mixture of the waste glass and thin-film transistor liquid crystal display glass frit 14-220 parts by weight as to the borosilicate system filament glass batch composition among the batch composition about 100 parts by weight of limestone and it does so that for the weight ratio which the waste glass occupies in the mixture of the waste glass and glass frit is 1:0.05-9, or relative to 100 parts by weight of limestone, the batch composition comprises 29-400 by weight parts of mixture of the cullet and waste glass, wherein the weight ratio between the cullet and the waste glass in the mixture is 1:0.05-9. The cullet and the waste glass are alkali-free aluminum oxide borosilicate glass which is used on a glass substrate for a TFT of a liquid crystal display device. Therefore, generation amount of waste can be reduced. Furthermore an effect of reducing cost and fusion energy of an ingredient composition is realized.

Description

technical field [0001] The present invention relates to an ingredient composition, which combines cullet produced in the commercial production process of glass substrates for thin film transistor liquid crystal displays (TFT-LCD), waste glass produced in the commercial production process of thin film transistor liquid crystal display panels The mixture is reused as a raw material for borosilicate-based long-fiber glass while maintaining the manufacturing process and physical and chemical properties of the long-fiber glass. Background technique [0002] Alkali-free alumina-borosilicate-based display glass substrates used in TFT-LCD panels are uniformly mixed with materials such as SiO 2 、Al 2 o 3 , B 2 o 3 And the composition of alkaline earth oxide (MgO+CaO+SrO+BaO), so it is a high-grade glass substrate with extremely high uniformity. The function of the display glass substrate is to protect the core components of the display and transmit images, so the quality control...
