液晶显示器玻璃基板技术与市场分析

目前,制造液晶显示器用平板玻璃的方法主要有3种：浮法工艺、槽口下引工艺和溢流下拉工艺。浮法工艺是目前最通用的平板玻璃制造技术。熔融玻璃液经锡槽成形,再经退火、切裁等制成。浮法技术生产厚度小于2mm,且平整度高的超薄平板玻璃,工艺条件难于控制,一般平板玻璃制造企业无法掌握。

Synthesis of Zeolite A from Aluminoborosilicate Glass Used in Glass Substrates of Liquid Crystal Display Panels and Evaluation of Its Cation Exchange Capacity

Synthesis of zeolite A from aluminoborosilicate glass used in liquid crystal display (LCD) panel glass substrate was attempted. Mixture of aluminoborosilicate glass and sodium aluminate was hydrothermally treated with sodium hydroxide solution for 10.8–345.6 ks at 368–423 K. Aluminoborosilicate glass was also acid treated with nitric acid before hydrothermal treatment. Obtained samples were characterized by X‐ray diffraction and scanning electron microscope observation. Zeolite A, hydroxysodalite, and zeolite P were synthesized, and with the specific conditions of hydrothermal treatment, a single phase of zeolite A was successfully obtained. Acid treatment was effective for synthesis of a single phase of zeolite A, because the components of aluminoborosilicate other than SiO₂ preferentially eluted for acid solution and during following hydrothermal treatment SiO₂ was supposed to elute for alkaline solution. Cation‐exchange capacities (CECs) were investigated for these products. It was clarified that CEC of the product with a single phase of zeolite A obtained from aluminoborosilicae glass was 4.2 mol/kg. CEC of the product consisted of zeolite A and hydroxysodalite was 3.9 mol/kg, and the one consisted of zeolite A, hydroxysodalite, and zeolite P was 2.6 mol/kg. This results shows that aluminoborosilicate glass could be expected to be recycled in zeolite A with good CEC by the appropriate process.

Formation of Barrier Ribs for Plasma Display Panels via Powder-Blasting Process: Part II, Effects of Powder-Blasting Angle

The effects of powder-blasting angle on the powder-blasting rate of a thick film prepared using a tape-casting technique were investigated. The results revealed that the etching rate was sensitive to the angle of powder blasting. The mechanism of this dependency was discussed based on brittle fracture and erosion caused by the powders blasted on the surface of the film. In addition, a new processing route for barrier ribs for plasma display panels was attempted, using the sensitive dependency of the etching characteristics on the powder-blasting angle. It was demonstrated that the ribs could be processed successfully using layers having different etching rates.
