摘要
以高密度聚乙烯(HDPE)、石蜡为相变主材料,活性炭为吸附载体材料,采用熔融共混法制备了HDPE/石蜡/活性炭三元相变储能材料,并分别利用真空烘箱和差示扫描量热仪(DSC)对该相变储能材料的宏观相变转换温度和热性能进行了表征。结果表明:随着HDPE/石蜡/活性炭相变储能材料中石蜡含量的增加(HDPE的含量相应减少),活性炭对石蜡的吸附能力相对降低;HDPE/石蜡/活性炭相变材料中,HDPE的实际焓值高于其理论焓值。
With high density polyethylene（HDPE） and paraffin as the main components of phase change material and activated carbon as the adsorption carrier material, a kind of ternary phase change energy storage material was prepared by melt blending method. The temperatures of macroscopic phase change transformation and thermal properties of the ternary phase change materials were characterized by vacuum oven and different scanning calorimeter（DSC）, respectively. The results show that： with the increasing content of the paraffin（and the content of HDPE correspondingly decreases）, the adsorption capacity of activated carbon for paraffin decreases. In the composite phase change material, the practical enthalpy of HDPE is higher than the theoretical enthalpy.
