摘    要:研究了不同吸水倍率的高分子吸水树脂的相变温度、相变潜热及作为蓄冷材料在35℃环境下的相变时间,并与冰做了对比。结果显示:吸收不同倍率水的高分子树脂,相变温度和相变潜热基本与水相似,随着吸水倍率的增加,相变潜热越接近于水的潜热;在相同条件下放置于隔冷袋中的高分子吸水树脂,在35℃的高温环境中,可以维持20℃以下低温5h,比冰多了将近1h,克服了渗漏的缺点,在蓄冷领域表现出了明显的优势。

关 键 词:高分子吸水树脂  蓄冷剂

Abstract:Phase change temperature,phase enthalpy of super absorbent polymers with different water absorbent rate,and the cool releasing time by using its as cool storage material under 35℃ were researched.Which was compared with ice.The results showed that phase change temperature and phase enthalpy that was nearer to ice with the increment of water absorbency of the super absorbent polymers with different water absorbent rate were similitude with ice.In addition,in the same temperature environment,the cool releasing time of the super absorbent polymers was one hour longer than that of ice.which had good advantages in cold storage field.
Keywords:super absorbent polymer  accumulating cold agent  ice
