摘　　要：十水硫酸钠作为相变材料应用前景广阔,但是存在严重的分层现象,影响其使用效果。本文采用均匀设计软件进行了十水硫酸钠防分层剂研究,选取了五种不同的增稠剂来防止体系分层,考察了各个物质不同加入量对十水硫酸钠分层现象的影响,得到防分层剂的最佳配方。最佳配方(质量分数)为羧甲基纤维素(0.213%),聚丙烯酰胺(0.243%),白炭黑(0.968%),丙烯酸吸水树脂(0.738%),黏土(0.567)。当体系中加入此防分层剂(3%)后,十水硫酸钠相变体系无分层现象且稳定性良好。As phase change material, Na2SO4?10H2O has wide application, but the serious stratification influ-ences its effects. Uniform design software was used to prepare the anti-layered agent of phase change material on Na2SO4?10H2O to get the best formula. It could be gained from the experiment that the optimum formula was: CMC (0.213%), polyacrylamide (0.243%), silica (0.968%), acrylic water-absorbent resin (0.738%), clay (0.567%). When the anti-layered agent was added, it was stability and there was no stratification.
