摘要: 传统真空玻璃支撑柱采用人工或机器布放,存在生产效率低、漏布率高等缺点。本文采用低熔点玻璃浆料印刷烧结制备支撑柱,优化了支撑柱印刷浆料调和浓度及印刷板参数,分析了不同烧结温度对支撑柱成型尺寸和强度的影响。结果表明,优化后的浆料调和浓度为5 g/mL,优化后的印刷板孔径为1.0 mm,厚度为0.5 mm,支撑柱最佳烧结温度为380 ℃,成型后支撑柱直径为1.25 mm,高度为0.23 mm,硬度达549.92 HV,性能较好。该研究对真空玻璃制造工艺具有指导意义。

Abstract: The traditional vacuum glass support pillar is manually or mechanically arranged, which has the disadvantages of low production efficiency and high leakage rate. In this paper, a support pillar was prepared by printing sintering of low melting point glass slurry, the blending concentration and printed plate parameters of the support pillar printing slurry were optimized, and the effects of different sintering temperatures on the molding size and strength of the support pillar were analyzed. The results show that the optimized slurry blending concentration is 5 g/mL, the optimized pore size and thickness of the printed plate are 1.0 mm and 0.5 mm, the optimal sintering temperature of the support pillar is 380 ℃. The diameter of support pillar after molding is 1.25 mm, the height is 0.23 mm, the hardness is 549.92 HV, and the performance is good. This study has guiding significance for the vacuum glass manufacturing process.
