静电纺丝作为制备纳米纤维膜的主要技术,在控制方面仍然存在精确度不高等缺陷,为此设计了一种以PLC为控制核心,通过传感器和AD/DA转换模块对纺丝过程参数进行实时检测与修正并显示在触摸屏上,同时步进电机与多轴运动控制方式的结合在很大程度上提高了制备系统的控制精确度。实验结果表明,本设计达到了对二维纳米纤维膜精确制备以及动态监测的目的。 Electrospinning as the main technology for preparing nanofiber membranes, there are still some defects such as low accuracy in control. To this end, a PLC-based control core is used to conduct the spinning process parameters through sensors and AD / DA conversion module in real time Detection and correction and displayed on the touch screen, while the combination of stepper motor and multi-axis motion control system to a large extent improve the control accuracy of the preparation system. The experimental results show that the design achieves the precise preparation and dynamic monitoring of two-dimensional nanofiber membrane.
