At the same time , the conductivity factor and the entropy of phase change of the solidation fatty alcohol were measured separately by using the time - temperature curve and dsc 同時(shí)利用時(shí)間-溫度曲線法和dsc測(cè)定了固化十二醇的導(dǎo)熱系數(shù)與相變焓。
Because of the small conductivity factor of organic phase change materials , all kinds of copper grids , gas sio2 and organic bentonite were added to organic phase change materials in order to heighten its conductivity factor . the conductivity factors were maesured by using time - temperature curve and comparison curve , and , the conductivity factor curves were drawn . at the same time , the entropy of phase change of every system was determined by using dsc 針對(duì)有機(jī)相變貯能材料導(dǎo)熱系數(shù)小的缺點(diǎn),采取在其中添加各種形狀的銅網(wǎng)格、氣相sio _ 2和有機(jī)膨潤(rùn)土的方法來(lái)改善體系的導(dǎo)熱性能,利用時(shí)間-溫度曲線法和比較法兩種方法測(cè)定體系的導(dǎo)熱系數(shù),并且繪制了體系導(dǎo)熱系數(shù)的變化曲線;同時(shí)利用dsc對(duì)上面部分體系的相變焓進(jìn)行了測(cè)定。
