dc.description.abstract摘要 本論文進行PET塑料之等溫結晶模式之改良,並探討PET吹氣拉伸成型寶特瓶之瓶身與其瓶胚胚口之熱處理過程(退火過程)對其結晶度之影響。於低溫時,文獻中Malkin之等溫結晶模式有高估結晶速率之現象,而Takayanagi之等溫結晶模式則會低估結晶速率,此研究修正Takayanagi之等溫結晶模式,並以PET塑料實驗所得之等溫結晶曲線與之比對,最後得到一組此修正後模式之係數,於低溫下,此修正後之結晶模式較能準確地預測實際結晶之狀況。此研究同時亦利用此修正後之等溫結晶模式以模擬PET塑料在三種等冷卻速率下之結晶行為,所得之結果並與一組Avrami等冷卻速率結晶模式所預測之結果進行比較。此研究亦發現此修正後之模式可用於預測PET瓶胚胚口於熱處理過程之結晶現象,研究中另藉由熱壓實驗來模擬PET寶特瓶瓶身之熱處理過程,以探討熱處理過程中模溫與貼合時間對於寶特瓶結晶度之影響。由X光繞射法量測之結果發現,寶特瓶之結晶主要發生在瓶胚之吹氣拉伸過程中,而熱處理過程中之結晶現象,可能由於所產生之晶體過小,且分散不集中,以致無法顯現於量測之結果中。 關鍵字:結晶度、PET、吹氣拉伸成型、熱處理。zh_TW
dc.description.abstractABSTRACT A modification of an isothermal crystallization model for PET is proposed and the effects of heat treatment (annealing process) on the crystallinity of a PET stretch-blow bottle and the mouth part of its preform were investigated. At low temperatures, Malkin's model over-estimates the crystallization rate for PET; conversely, Takayanagi's model under-estimates it. This work proposes a modified Takayanagi's model. Through a comparison with a set of isothermal crystallization lines, the coefficients in the model were obtained. At low temperatures, this model provides a better prediction of the crystallization. This model was also employed in simulation of the crystallization of PET for three cases under various cooling rates. The result was compared with that predicted using Avrami's constant cooling rate model. In this work, it was found that the modified model can not be used to predict the crystallization of the stretch-blow bottle during heat treatment. However, it yields a reasonable result in predicting the crystallization of the preform. A hot-compression experiment was used to simulate the heat treatment of the PET stretch-blow bottle. The effect of mold temperature and attaching time on the crystallinity was investigated. The result of the X-ray diffraction measurement reveals that, the crystallization for the PET bottle mainly is determined during stretch-blowing. The increase of the crystallinity through the heat treatment could not be observed from the measured data. This probably is because the increased crystals are too small and too diffuse. Thus the X-ray diffraction measurement could not detect their presence. Keywords : crystallinity, PET, stretch-blow, heat treatmenten_US
