摘要
为获得最佳的熔体微分静电纺丝结构参数,采用有限元分析软件ANSYS对多层锥面无针熔体微分静电纺丝中的电场分布进行模拟,分析了双锥面特征设计参数对纺丝尖端场强的影响,分别讨论了内圈直径和内圈伸出距离对内外圈纺丝尖端及纺丝路径场强分布的影响。ANSYS数值模拟结果表明:增加锥面层数会减弱最外圈纺丝尖端的电场强度;对于双锥面熔体纺丝装置,内锥面直径大小对纺丝尖端场强分布的影响不明显;当内锥面伸出距离增大时,内外圈纺丝尖端场强的差值先减小再增大;当内锥面直径为26 mm,内圈伸出距离为6 mm时,内外圈纺丝尖端电场强度分布最相似,能够保证内外锥面制备的纤维射流间距相同,实验结果和模拟结果一致。
In order to obtain optimized structural parameters of melt differential electrospining, finite element analysis software （ANSYS） was employed to simulate and analyze the distribution of the electric field intensity in multiple cone needleless melt differential electrospinning. The influence of design parameters on the electric field intensity was analyzed. The effect of inner diameter and extend distance on the electric field intensity distribution of spinning edge and spinning path was discussed respectively. The results indicate that the electric field intensity of the spinning edge was weakened with the increasing cone number, and for double cone needle-free melt differential electrospinning, the influence of inner diameter size on electric field intensity distribution of spinning edge is not obvious. While the extend distance of inner cone increase gradually, the difference value of electric filed intensity between inner and outer cone is found to decrease firstly and then increase. In particular, the electric filed intensity distribution of inner and outer cone is the most similar and the jet spacing of inner and outer cone is almost identical when the inner cone diameter is 26 ram, and inner extend distance is 6 mm. The experimental results are consistent with the simulation results.
