Rheological Analysis of Polymeric Melt Flow in a Wire Coating Die

김동표, 박헌진, 이기준

초록

본 연구에서는 전선피복 die내 고분자 물질의 이동현상에 관하여 Carreau model을 도입하여 유한요소법으로 수치해석을 수행하였다. Polyvinyl chloride(PVC)의 유변상수들의 변화가 유동에 미치는 영향을 조사하였고 온도에 따른 점도의 변화를 고려한 비등온 조건 및 전선 피복 공정에서 발생할 수 있는 slip 경계조건을 적용시킨 경우에 대한 수치모사도 수행하였다.

The flow phenomena through a wire coating die are quantitatively analyzed using Carreau model by a finite element method. The effect of the rheological parameters for polyvinyl chloride (PVC) melt and tion is also incorporated to account for the fluid slip along the fast moving wire and the stationary die wall.

Keywords:Wire Coating;Polymer Rheology;Computer Simulation
