85　Study on manufacturing process to suppress pressure increase 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 results of the experiment showed that after heating for 8 hours and vacuuming with two getter materials sealed, the internal pressure of the TVIP could be further reduced than before.
