摘　　要：采用理论分析和试验研究相结合的方法,研究了微孔发泡注射成型工艺问题。结果表明:过饱和压力越高,气泡稳定膨胀所需的临界气泡半径越小,均相成核率越高,气泡长大越快。气体含量越高,成核速率越大,气泡成长速率降低,尺寸减小,更易达到微孔结构。The research method of theoretical analysis combined with experimental study is used to study the technologies of Microcellular foaming injection molding.The results show that high supersaturated pressure makes the bubble radius of steady bulge small and the speed of bubble growing fast.High content of gas makes the nucleation rate fast and makes the bubble growing speed slow,which is easier to form microcellular configuration.
