摘　　要：研究了成核剂类型、成核剂粒度、成核剂含量、振动参数对微孔发泡塑料泡孔形态的影响。通过对模拟振动挤出过程PS发泡的实验研究表明:加入适当的成核剂能较好地改善泡孔形态,同时振动力场的引入有利于成核剂的均匀分散,形成均匀致密的气泡。The influences of nucleating agents type, particle size of nucleating agents, content of nucleating agents, and vibration parameters on cell morphology of formed plastics were investigated. Some conclusions were obtained from experimental research on vibration simulation extrusion process of polystyrene foaming. The results indicated adding of appropriate nucleation agents could improve the cell morphology of foamed plastics, and introduction of vibrating force field could promote the homogeneous dispersion of nucleation agents, forming homogeneous and dense cells.
