摘要

水合盐是一种储热能力强的相变材料，应用领域广泛，但本身存在的过冷问题会严重影响其应用。通过添加金属氧化物颗粒能够有效降低其过冷度，同时进一步提升储热性能。因此，本研究以KAl(SO

)

·12H

O-MgSO

·7H

O二元共晶水合盐为储热基材，采用熔融共混法在二元共晶水合盐相变材料中微量掺杂两种氧化铝颗粒以调节水合盐的储热性能。通过分析材料相变特性确定最佳Al

颗粒及添加量，对Al

颗粒掺杂前后材料的热物性和热稳定性进行了研究。结果表明，γ-Al

对过冷度的改善效果优于α-Al

，γ-Al

颗粒最佳添加量为0.3%。掺杂0.3% γ-Al

后复合相变材料的过冷度为6.2℃，相较基材降低了33.3%；熔点和热分解温度较基材几乎不变；相变潜热为459 J/g，较基材升高了16.5%；在80℃下保温168 h，过冷度为3.5℃，其仍能保持良好的热稳定性。本研究将为实现水合盐相变储热材料在建筑节能和工业余热回收领域的高效利用提供参考。

Abstract

Salt hydrates are phase change materials with high heat storage capacity and wide application potential. However

supercooling seriously limits their use. The addition of metal oxide particles can effectively reduce its supercooling and further enhance its heat storage performance. Herein

KAl(SO

)

·12H

O-MgSO

·7H

O binary eutectic salt hydrates were selected as the heat storage matrix

and two types of Al

particles were separately slightly doped through melt blending to regulate the heat storage performance of the hydrated salt. The optimal alumina type and doping amount were determined by analyzing phase change characteristics. The effect of Al

particles on thermophysical properties and thermal stability of the binary eutectic salt hydrates was analyzed. Results show that γ-Al

suppresses supercooling more effectively than α-Al

. With 0.3% γ-Al

the supercooling degree of the composite PCM is 6.2℃

33.3% lower than that of the substrate. The melting and thermal decomposition temperatures remain almost unchanged

and the melting enthalpy reaches 459 J/g

16.5% higher than that of the substrate. After storage at 80℃ for 168 h

the supercooling degree is 3.5℃

maintaining good thermal stability. This study provides guidance for t efficient application of hydrated-salt phase-change heat-storage materials in building energy conservation and industrial waste heat recovery.
