Paper Abstract

A novel image measurement with computed digital tomography was developed for the conformation and structure of polymer material during extrusion in the paper. It is difficult to measure the configuration and structure of polymer material during extrusion. On the basis of the relation of polymer free volume and the temperature, pressure and viscosity during extrusion, the method synthetically utilizes the knowledge of nuclear physics, photo-electricity, mechanism, computer technology and mathematics, the dynamic configuration and flow behavior of polymer can be visually obtained by the interaction of the atom of polymer or polymer chain and the photon beam to come from gamma ray, in which the photoemission, Compton effect and electron pair effect will be generated. The experimental result indicates the method can not only measure the dynamic conformation and structure of extrusion polymer in the way of non-open, non-destroy and on-line, but also deduce the relationship between the mechanical properties and the conformation of extrusion polymer.
