The gelation with complete cooling time of 40min had a high yields and encapsulation efficiency , and the process may be contrplled . the micropcms was stable and its diameter was uniformity . the thermal profile of microcapsule was not affected by the ratio of gelation , but the thermal was not good enough 結果表明:以明膠-阿拉伯樹膠為壁材制備的相變儲熱微膠囊平均粒徑均勻;壁材完整,包覆效果較好;熱分析顯示,相變儲熱微膠囊具有自調溫功能,但明膠-阿拉伯樹膠為壁材的微膠囊熱穩定性較差。

First , the low profile performance of up / lpa / styrene system is governed by two critical steps : the phase separation and the microvoid formation . second , the cure of the low profile unsaturated polyester resin can be divided into four periods : induction , phase separation ( including spinodal decomposition and coalescence and growth ) , gelation and microvoid formation 指出:相分離以及微孔的形成是決定up田l隊/苯乙烯三相系統低收縮性能的關鍵,低輪廓不飽和聚醋樹脂的固化可以分成四個階段:引發、相分離(包含兩種類型:旋竹線分離以及合井與長大) 、凝膠和微孔形成。
