Abstract

Numerical simulation and experimental verification were carried out on polymer removal from a PIM compact by thermal debinding. An integrated model, considering the interactive effects of various mechanisms, is proposed. It avoided the necessity of making the unrealistic assumption of a receding liquid/gas interface front, which is commonly employed by other models. From the numerical and experimental investigations, it is revealed that the distribution of polymer residue is a smooth continuous function of distance. The phenomenon observed experimentally by other researchers, namely enrichment with liquid polymer in the outer surface region of the compact, was predicted numerically and observed experimentally. The results of numerical simulation are in good agreement with experimental observations.
