摘要 以超临界CO2为发泡剂,用自制的动态模拟发泡装置研究了振动参数(振动频率和振动幅度)对聚碳酸酯(PC)微孔泡沫泡孔形态的影响。研究发现,在其他加工参数相同的条件下,振动频率越高,最终得到的泡孔形态越好,而对于振幅则存在一最佳值,在本实验条件下,振幅为75μm时得到的PC微孔发泡材料的泡孔形态最佳。 With supercritical CO 2 as foaming agent, the effect of vibration on cell morphology of micro- cellular formed polycarbonate （PC） plastics was studied on a self-designed dynamic simulation foaming set- up. Research showed that as other processing conditions were the same, microcellular formed PC plastics with better cell morphology could be obtained as vibration frequency increased, and there existed optimum vi- bration amplitude for microcellular foaming of PC. Under the processing conditions determined in this study, when vibration amplitude was 75 μm, microcellular foamed PC plastics with the optimum cell morphology were obtained.
