초록

폴리(에틸렌 테레프탈레이트)(PET)의 사출 성형을 효과적으로 수행하기 위해서는 결정화 속도를 증대시키는 것이 필수적이다. 본 연구에서는 PET의 결정화 속도에 대한 용융 전단의 효과를 사출 전후로 나누어 조사하였다. 사출 전 시료의 경우에는 용융 전단의 효과가 핵제의 효과보다 우세한 것으로 관찰되었다. 반면에, 사출 시편의 경우에는 용융 전단의 효과가 뚜렷하게 나타나지 않았다.

In order to enhance the molding efficiency for poly(ethylene terephthalate) (PET) resins in injection molding, the increased crystallization rate of PET should be required. In this study, we investigated the effect of melt shearing on the crystallization rate of PET before and after injection molding. For the samples before injection molding, the effect of melt shearing on the crystallization rate was superior to that of nucleating agent. On the contrary, the effect of melt shearing was not significant for the samples after injection molding.

Keywords:poly(ethylene terephthalate);injection molding;crystallization rate;melt shearing
