制备了硬脂酸和62#石蜡组成的二元混合相变材料,通过差式扫描量热仪研究了其相变温度和相变潜热的变化规律。同时实验研究了添加石墨后硬脂酸、62#石蜡以及硬脂酸与62#石蜡复合相变材料的相变温度和相变潜热。以期为复合相变材料在储能领域的应用提供参考。
The mixed phase change materials(PCM) composed of stearic acid and 62# paraffin were prepared.The phase transition temperature and the latent heat of phase change were studied by differential scanning calorimetry.At the same time,the phase transition temperature and latent heat of phase change of stearic acid,62# paraffin and stearic acid and 62# paraffin mixed PCM were studied experimentally.The results can provide reference for the application of composite PCM in energy storage.
