Abstract

The paper concentrates on the skills of tomography image processing and analysis for polymer configuration in polymer extrusion. Firstly, the tomography image segmentation is brought forward to resolve the problem that the amount of polymer information is small and the tomography image resolution is low, which comes from the great difference of physical dimension and material density between polymer (object) and processing equipment (background). And then, the object region extraction is performed to distinguish object region from segmentation image. Under the guidance of basic theory on polymer processing, the object configuration and its characteristics have been obtained by the tomography image measurement from the object region. The rheological property of polymer can be analyzed by the characteristics of object tomography configuration. Finally, the experiment result shows that this method can measure and analyze the polymer configuration and improve the measurement system resolution effectively. It has offered a novel experimental method to solve the problem that engineering material configuration in enclosed and complicated space is detested dynamically and nondestructively.
