塑料成型中聚合物的壁面滑移现象

摘要

重点阐述了目前3种主要的聚合物壁面滑移机理,介绍了几种常见的壁面滑移模型,并就相关影响因素进行了论述.最后介绍了国内外学者所取得关于壁面滑移的成果,针对壁面滑移的测量、数学建模、仿真等问题,给出了建议.%Three main machanisms of polymer wall slip are mainly reviewed. Wall slip and normal wall slip modes are demonstrated,and some related factors are discussed. At the end,some frontier achievements at home and abroad about wall slip are introduced. According to the problems in wall slip measurement, mathematic model and simulationect, some suggestions are given.
