在芒硝贮热物质中加入晶习改变剂P—6或S—12或P—A 等能有效阻止芒硝晶体颗粒增大,因此能保持较高的熔化热,从而大大延长贮热物质的使用寿命.
Glauber’s heat storage material in the crystal change agent P-6 or S-12 or P-A, etc. can be effective in preventing Glauber’s salt crystal particles increase, it can maintain a high heat of fusion, which greatly extend the life of thermal storage material .
