摘要:

铂金通道是电子显示玻璃生产中最为关键的装备之一。本文针对铂金通道结构中上升段的角度变化对玻璃液中气泡运动行为的影响展开研究,通过结构和尺寸设计,构建模型-实际几何比例为1∶4的物理模拟实验平台,以聚二甲基硅氧烷为模拟液,结合相似准则(雷诺数、伽利略准数),系统分析了23°、30°、45°三种铂金通道上升段倾斜角度下气泡的运动特征与分布规律。结果表明,模拟液的实测运动黏度与理论计算运动黏度具有良好的相似性。铂金通道上升段的角度变化对玻璃液与气泡运动有着较大影响。当铂金通道上升段的倾斜角度由23°变化到45°时,其出口处的气泡更加集中分布于管道截面上部,对气泡的抬升效果明显,并在综合分析后,发现倾斜角度为30°时效果最优。在本研究范围内,铂金通道上升段倾斜角度的增大强化了气泡浮力与流体动力的协同作用。

Abstract:

Platinum channel is one of the most critical pieces of equipment in the production of electronic display glass. This paper studied the influence of inclination angle changes in ascending section of platinum channel structure on movement behavior of bubbles in molten glass. A physical simulation experimental platform with a model-actual geometric ratio of 1∶4 was constructed through structural and dimensional design. Polydimethylsiloxane was used as the simulated liquid, combined with similarity criteria (Reynolds number, Galileo number), the movement characteristics and distribution laws of bubbles were systematically analyzed under three inclination angles of the ascending section of platinum channel: 23°, 30°, and 45°. The results show that the measured kinematic viscosity of the simulated liquid has good similarity with the theoretically calculated kinematic viscosity. Changes in the inclination angle of ascending section of platinum channel have a significant impact on the flow of molten glass and the movement of bubbles. When the inclination angle of ascending section of platinum channel changes from 23° to 45°, the bubbles at its outlet are more concentrated in upper part of the pipe cross-section, and the lifting effect on bubbles is obvious. After comprehensive analysis, it is found that the effect of a 30° inclination angle is optimal.Within the scope of this study, an increase in the inclination angle of ascending section of platinum channel strengthens the synergistic effect between bubble buoyancy and fluid dynamics.
