Studies of structures of copper phthalocyanine films grown by vacuum sublimation
酞菁銅納米微粒的制備及其聚集態行為 -
Results showed that moisture content was mostly removed during sublimation period of freeze - drying, while rapidly dropped during earlier period of air - drying and gradually decreased during vacuum belt drying
結果表明：真空冷凍乾燥物料中的大部分水分在升華階段去除，熱風乾燥初期水分含量迅速下降，真空帶式乾燥物料水分隨時間延長呈比較均勻的下降。 -
The results indicate that drying thickness, radiant temperature and pressure of drying chamber are the most three significant factors. there ' s hardly any relationship between freezing rate and drying time, the sublimation drying time of slow freezing material is shorter than quick freezing one, but its desorption drying time is relatively longer, so the total drying time is approximately the same. the initial freezing temperature and freezing manner has little influence on vacuum freeze drying process
試驗表明：凍干厚度、加熱板溫度、系統的真空度是最重要的三個過程參數；凍結速率對總凍干時間沒有影響，慢凍物料的升華乾燥時間要比快凍物料短，但慢凍的解析時間相對較長，兩者的總凍干時間相差很小；初始凍結溫度對凍干過程的影響可以忽略。 -
Cdte films deposited by close space sublimation have better appearance and larger grain than the films deposited by rf - sputtering and vacuum thermal evaporation
