摘　　要：考察了混炼时间、混炼温度、剪切力、增塑剂用量、加工改性剂用量对PVC树脂"假鱼眼"数的影响.结果表明:以上5个因素均会影响PVC树脂的"假鱼眼"数,其中混炼时间、增塑剂用量对PVC树脂"假鱼眼"数的影响尤为明显.The effects of mixing time,mixing temperature,shear force,plasticizer content and processing modifier content on pseudo-fisheye number of PVC resins were investigated.The results showed that the above five factors could affect the pseudo-fisheye number of PVC resins,especially the mixing time and the plasticizer content.
