Abstract

Abstract: In low temperature storage and transportation, due to the outgassing of materials in the vacuum interlayer, the vacuum degree of the interlayer will decrease, the heat will be introduced from the outside to increase the evaporation rate of the low temperature container and the loss of low temperature liquid, and the vacuum life will be shortened. Therefore, it is very important to study the outgassing properties of materials in vacuum interlayer. In this paper, the outgassing rate of multilayer insulation material and FRP in vacuum for low temperature storage tank is tested and studied. The outgassing rate per unit area of multilayer insulation material and D3848 FRP is 4.93×10^-8Pa·m³/(s·m²) and 1.13×10^-7Pa·m³/(s·m²). The results can provide a reliable basis for the design of adsorption dose of vacuum interlayer.

Key words: FRP, multi-layer material, outgassing rate
