摘要
本文把十酸和十四酸按四种不同比例进行复合,并对四种二元相变材料进行了一系列的实验研究。通过DSC测试,最终得到了四种二元相变材料以及两种纯物质的相变温度和焓值。实验数据显示,二元相变材料中十酸与十四酸质量比为3：1时相变温度最低,为20.0℃;质量比为1：1时相变温度最高,为26.7℃。相变焓值在130~190J/g之间。
The capric acid and mistiric acid were compound into four types of binary complex phase change materials according to four different proportions,and a series of experiments were done.The phase transition temperatures and enthalpy values of four kinds of binary complex phase change materials and two kinds of pure substances were obtained eventually by the DSC test.Experimental data show that the lowest phase transition temperature is 20.0 ℃ when the mass ratio of capric acid and mistiric acid is acid 3：1;the highest is 26.5 ℃ when 1：1.Enthalpy values are between 130 J/g to 190 J/g.
