复合定型相变储能保温材料月桂酸-膨胀珍珠岩试验研究

摘要

由月桂酸-膨胀珍珠岩构成的相变材料，对其进行SEM、差热分析、月桂酸的渗出率分析来研究材料的稳定性。研究表明，月桂酸与膨胀珍珠岩能够很好的融合，并且在一定的比例范围内可以有效减少月桂酸的渗出。这一成果可为相变材料在实际工程中的应用提供技术支持。%For phase change materials composed of lauric acid and expanded perlite , we study material ’ s stability by analyzing the SEM , leaching rate of expanded perlite and differential thermal .Research shows that lauric acid and ex-panded perlite can be combined , and in certain proportion range , the lauric acid exudation can be effectively re-duced .results can provide technical support for the application of phase change materials in practical engineering .
