This article choosed out organic phase change materials, and, the solid - liquid - equilibrium of eleven binary system including fatty alcohol / fatty acid, n - octadecane / fatty acid, n - octadecane / fatty alcohol system were determined by cooling curve, and, t - x phase diagrams of these systems were drawn. the result shows that all these systems are simple eutectic, at the same time, the entropy of phase change of every system in the eutectic point is determined by using differential scanning calorimetry ( dsc ). and n - octadecane / fatty acid systems were calculated theoretically
本文初選出部分有機相變貯能材料，採用步冷曲線法測定了12醇-羧酸系列、 18烷-羧酸系列、 18烷- 12醇體系共11組體系的二元固液相平衡關系，繪制了這11組體系的t - x相圖，測定結果表明，這幾組體系均為簡單低共熔體系；同時利用差熱掃描量熱法（ dsc ）對上面各組體系低共熔點處的相變焓進行了測定；並對18烷-羧酸系列進行了熱力學理論預測。 -
The s - l - e experiment data for the eight binary condensed systems of fatty alcohol / fatty acid were treated by using the improved equation, and the equation was examined with experimental data. at the same time, we used ideal model to predict the tenary s - l - e of n - octadecane / lauric acid / stearic acid system, and we got an accurate result of the simple eutectic temperature. the relative error is 0. 51 % comparing with the experimental result, so we will offer a method of prediction for quickly obtaining multicomponent system phase change materials this article calculated the pcms quantities and energy saving effect in theory, designed the experimental apparatus to measure the energy saving effect, and analyzed the temperature equalization action of the pcms by comparing experiment
利用這種方法，建立了適合醇-羧酸等系列二元體系的單參數margules方程，本文對醇-羧酸系列等8個二元凝聚體系的單參數margules方程的參數進行回歸，並利用整個實驗數據對模型進行了檢驗，另外，本文利用理想狀態模型對一個三元體系18烷-月桂酸-硬酯酸相圖進行預測，通過與實驗數據進行比較，預測的低共熔溫度與實驗測定溫度較為吻合，其相對誤差為0 . 51 ，這將為快速獲取多元體系的相變材料提供預測方法。 -
Last, polyurea microcapsule containing octadecane as phase change material was successfully synthesized by interfacial polycondensation using tdi and deta as shell monomers in an emulsion only by reaction of tdi and deta, but also reaction of tdi and amines which are formed by hydrolysis of tdi at the interface
制備聚脲樹脂微膠囊的過程不僅包括tdi和deta的反應，還包括tdi與自身水解產物的界面反應。 tdi與deta反應質量比為3 ： 1 。另外， np - 10還與tdi反應生成脲烷。 -
In experimental research, the s - l - e of eleven binary system including fatty alcohol / fatty acid, n - octadecane / fatty acid, n - octadecane / fatty alcohol system were determined by cooling curve. at the same time, the s - l - e of one ternary system of n - octadecane / fatty acid / stearic acid was measured by pseudo - duality, and t - x phase diagrams of these systems were drawn
在實驗的研究中，採用步冷曲線法測定了12醇-羧酸系列、部分18烷-羧酸體系、 18烷- 12醇體系共11組體系的二元固液相平衡關系，同時採用擬二元法測定了18烷-硬酯酸-月桂酸體系的三元固液平衡關系，繪制了這12組體系的t - x相圖。 -
There are still knowledge gaps between fabrication and properties of nano - and microencapsulated phase change materials. the present research has investigated improving their thermal stability and preventing them from super - cooling in order to fabricate micropcms and nanopcms with higher performances. micropcms and nanopcms were synthesized by encapsulating n - octadecane and the other components within the melamine - formaldehyde ( abbr
