摘要
采用自主设计的狭缝式熔体微分静电纺丝装置，使用聚丙烯（PP）材料进行熔体静电纺丝，研究了电压对射流根数的影响，同时探究了辅助气流对纤维直径的细化作用。试验结果表明：当挤出机端温度为200％，流道温度为230℃，纺丝距离为90mm，流量大小为0．8g／min时，射流根数随着电压增大而增加；当电压为50kV时，射流根数达到最大，为24根。纤维直径随辅助气流速度的增大而减小；当电压为50kV，辅助气流速度为8m／s时，纤维平均直径可达到1．55μm。
Based on self-made slit melt differential electrospinning device, polypropylene （PP） melt is electrospun into fibers, the effect of voltage on the number of jet roots is studied, and the refining effect of auxiliary air flow on fiber diameter is also investigated. The results show that when the extruder temperature is 200℃, the channel temperature is 230~C, the spinning distance is 90mm and the flow rate is 0.8 g/min, the jet root number increases with the increase of voltage, and when the voltage is 50 kV, the maximum number of jet roots is 24. The fiber diameter decreases with the increase of the airflow velocity, when the voltage is 50 kV and the auxiliary airflow velocity is 8 m/s, the average diameter of the fiber is 1.55μm.
