The Applications of Vacuum Drying Technology in the VIP Core Material’ Pre-Treatment

Abstract

This paper researched the mechanism and model of moisture transfer in the core material of VIP- glass fiber, and introduced the vacuum drying technology to enhance the gas molecules’ movement under vacuum, accelerate the speed of water vaporization and avoid voids adhesion to overcome the adsorption resistance. The article also designed the equipment to provide experimental possibilities for the theoretical study.
