摘要
通过熔融物理吸附法将月桂酸、活性炭复合制备得到复合相变储能材料。测试分析表明,复合相变材料的相变温度范围在44.61℃-46.51℃之间,并且有一个较大的吸热峰,可实现相变吸放热,热稳定性好,相变物质热性能基本不受影响。微相结构显示活性炭能有效吸入大量的月桂酸,具有较好的物理吸附结合能力。综合分析表明,该复合相变储能材料在储热、保温方面具有较好的应用参考价值。
Using lauric acid,activated carbon and so on,the composite was prepared in melting phase by physical adsorption.The test and analysis showed that its phase temperature range was between 44.61℃ and 46.51 ℃,and there was a large endothermic peak between them,which can realize heat absorption and heat releasing,with good thermal stability.Thermal properties of phase change material were not affected.Micro-phase structure showed activated carbon can effectively absorb large quantities of lauric acid.It had good combination capacity of physical adsorption.Comprehensive analysis showed that the composite had good application reference value in thermal storage and thermal insulation.
