提出一种实心针静电纺丝方法,采用实心针作为静电发射极,并将其置于由绝缘材料制成的导液棒轴心,导液棒处于储液盒底部的圆锥沉头通孔内部并可以做升降运动以控制供液量,需要时还可以起到通流的作用,有效地解决了多针头静电纺丝堵塞和无针头静电纺丝开放式供液的问题.利用COMSOL有限元分析软件对影响场强大小及分布的各参数进行场强模拟,研究增大场强并减小边缘效应的改进方法,并采用研发的不完全齿轮横动机构纺丝头做往复横动进行纺丝实验,验证了实心针静电纺丝装置有效降低了能耗和边缘效应,避免了针头堵塞及溶剂挥发问题.
A solid needle electrospinning method is proposed, which uses a solid needle as an electrostatic emitter and places it in an axis of a liquid guiding rod made of an insulating material. The liquid guiding rod is located inside the tapered countersunk head through hole at the bottom of the liquid storing box And can do lifting movements to control the amount of liquid supply, if necessary, can also play the role of through-flow, effectively solve the multi-needle electrostatic spinning clogging and needleless electrospinning open solution for the problem.Using COMSOL finite element analysis The software simulated the field strength of each parameter influencing the size and distribution of field strength, studied the improved method of increasing the field strength and reducing the edge effect, and used the developed head of the traversing mechanism with incomplete gear to make reciprocating traverse Experiments show that the solid needle electrospinning device can effectively reduce energy consumption and edge effects and avoid needle plugging and solvent evaporation.
