But conductivity factor of the organic phase change materials is very small , which limits its progress and use , and , becomes " bottleneck problem " of its use wide - rangingly 但是有机相变贮能材料导热系数小这一缺点严重限制它的发展和应用,成为其能否广泛实际应用的“瓶颈”问题。
Micro - encapsulated / nano - encapsulated phase change materials are novel composite phase change materials , which are prepared by micro - encapsulation and nano - encapsulation technology 摘要微纳米胶囊相变材料是将微胶囊化技术和纳米胶囊化技术应用到相变材料中而形成的新型复合相变材料。
The emphases in this paper are the measurement and analysis of thermal characteristics of stearic acid as phase change material and the design and simulation of the latent heat thermal storage radiator 全文共分为五个部分,硬脂酸相变过程中热性能的测试与分析、相变蓄热式电暖器的设计与模拟是本文的重点。
The result shows the conductivity factor of organic phase change materials was heightened , the temperature of phase change was changeless , and , the entropy of phase change was reduced after adding these additives 结果表明,加入上述添加物后,有机相变贮能材料体系的导热系数能有效地提高,相变温度几乎没有改变,相变焓会有所下降。
The strength of shell was evaluated through observing the surface change after pressure by means of scanning electron microscopy . the melting point of the microcapsules was 24 . 7 c , nearly equaled to the pure phase change material 此种微胶囊中的相变材料在发生相变时具有调温作用,将其应用于室内墙体材料中,可使墙体材料具有自调温作用。
