53. Experimental Investigation of Methods to Reduce Gas Emission from Core Material in the Manufacturing Process of Transparent Vacuum Insulation Panels

Abstract

In this study, an experimental apparatus was constructed for Transparent Vacuum Insulation Panels (TVIP), which can be easily installed as insulation for building windows, by applying the pressure-rise-rate method to establish a manufacturing process for TVIP that suppresses pressure increase. In this experiment, a gas barrier film with a straw was used as a vacuum vessel. The experimental results showed that the internal pressure of TVIP could be reduced to about 1 Pa after vacuuming while heating for 8 hours, coating the core material, and sealing the getter material.
