摘要
选用六水氯化锶作为成核剂,羧甲基纤维素(CMC)作为悬浮剂,进行300次冷热循环实验后对相分层样品进行分层取样,运用差示扫描量热法分别对各层样品进行相变潜热表征。实验表明,改性后材料相变潜热为144J/g;完成300次冻融循环后仍具备一定的储热性能,但完整性被破坏。
Select strontium chloride hexahydrate as nucleating, while using carboxy methyl cellulose (CMC) as suspending, After 300 times freeze-thaw cycle, usingdifferential scanning calorimetry to measure the change of phase change latent heat. These experiments show that the material' s phase change latent heat is 144J/g and it still has heat storage property after 300 times freeze- thaw cycle but its integrity had been destroried
