摘要
研制了一种新型三元复合相变蓄冷材料。利用差示扫描量热仪测量物质的性能,测得相变材料相变温度为-14℃,相变潜热为172J/g。主要成分是丙三醇、乙酸钠和水,原材料价格便宜且易购得,可以大规模应用于冷库冷藏、低温物流等领域。
A new phase change material which was formed by three different materials was prepared. The temperature and the latent heat of this material were measured by the Differential Scanning Calorimetry which was - 15℃ and 174. 1J/g. The component of this material were propanetriol,sodium acetate and water, all of them were cheap and easy to buy, so the new material can be used in the filed of refrigeratory and cryogenic transportation greatly.
