摘要: 提出了对成型中固体输送段聚合物进行计算机层析图像测量的新方法.该方法综合运用核物理学、光电子学、高分子物理、计算机技术和数学知识‚通过γ-射线的光子流与聚合物原子、聚合物链段相互作用所产生的光电效应、康普顿效应和电子对效应‚来图像化地测量固体输送段的聚合物形态.实验结果表明‚利用该方法不仅能对处于密闭空间的聚合物形态进行非破坏性在线测量‚而且可以推导出固体输送段聚合物形态与其性能的关系.

Abstract: This paper presents the image measurement and analysis method with computed tomography for polymer in solid conveying.It utilizes the knowledge of nuclear physics‚photo-electricity‚polymer physics‚computer technology and mathematics synthetically‚the polymer morphology in solid conveying can be visually obtained by the interaction of polymer atom or polymer chain and the photon beam caused by γ-ray‚in which the photoemission‚Compton effect and electron pair effect will be generated.The experimental results indicate the method can not only measure the deformation and morphology of polymer in the way of non-open‚non-destroy and on-line‚but also find the relationship between the morphology and the mechanical properties of polymer in solid conveying.

Key words: image measurement, computed tomography, extrusion theory, polymer morphology
