Printing Sintering Molding Process and Performance of Vacuum Glass Support Pillar

Abstract

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.
