摘要
介绍了Na2SO4·10H2O用作相变材料的储能特性,综述了针对Na2SO4·10H2O过冷和相分离现象的解决方法以及Na2SO4·10H2O某些共晶盐的研究,同时简要概括了各因素对Na2SO4·10H2O结晶速度的影响,展望了Na2SO4·10H2O未来的发展方向。Na2SO4·10H2O作为相变材料的研究主要集中在成核剂和增稠剂的选择,Na2SO4·10H2O的无机共晶盐表现出较好的储热性能,可以尝试研究在微、纳米级多孔限域作用下的无机水合盐及其共晶盐的储热性能。
The characteristics of Na2SO4· 10H2O as the phase change material are introduced. The ways to solve the supercooling and phase separation and some eutectic salts are reviewed. The effects of diferent factors on the velocity of crystallization are also summarized. The development direction of the inorganic phase change material Na2SO4· 10H2O in the future is pointed. In conclusion, the study on Na2SO4·10H2O as phase change materials is focused on the selection of nucleating agents and thickening agents and the inorganic eutectic salts ofNa2SO4· 10H2O are wonderful materials for heat storage, The study on heat storage property of Na2SO4·10H2O and its inorganic salt hydrates and eutectic salts under micron-nanoscale porous limiting fields can be attempted.
