Study on the influence of glass encapsulating on the hygroscopicity of high temperature phase change heat storage materials

Abstract

In this paper, Na2CO3-K2CO3 / MgO phase change composite was coated on the surface of glass by spray plating, which solved the problem of absorbing moisture and pulverizing of molten salt / MgO phase change thermal storage material in high humidity environment, and reduced the absorbing moisture and pulverizing rate from 31% to 19% without affecting the latent heat of phase change thermal storage material.
