Abstract

The invention discloses a bubble controllability research method in bubble spinning nanofiber production, and particularly relates to the technical field of bubble spinning nanofiber production. The method specifically comprises the following operation steps: establishing a bubble growth model; analyzing and determining a change rule of bubble wall thickness in a bubble growth process; analyzing ageneration condition of bubble film fragments; determining a condition of converting the bubble film fragments into a liquid column, and specifically analyzing a motion rule of the liquid column in an external electric field force or airflow. According to the method, a bubble growth model is established by utilizing the basic law of hydromechanics, the change rule of the bubble wall thickness inthe bubble growth process is analyzed by referring to the change rule of the planar liquid film thickness, and meanwhile, the condition of converting bubble film fragments into liquid columns is determined by utilizing the law of conservation of hydromechanics mass; and the movement rule of the liquid column in the movement of external electric field force or airflow is studied, so that the controllability of the bubble size in the bubble spinning nanofiber production is improved.

Description

technical field [0001] The invention relates to the technical field of bubble spinning nanofiber production, more specifically, the invention relates to a method for researching the controllability of bubbles in the production of bubble spinning nanofibers. Background technique [0002] Bubble spinning refers to the use of external airflow or electrostatic field to overcome the surface tension of bubbles for spinning. In this process, the size of the bubble depends on the process of bubble growth and collapse, and its influencing factors include the way of bubble generation, air inlet speed, diameter of air inlet, air inlet density, etc., which is a very complicated process. In the process of bubble growth, the surface area of ​​the bubble film increases, and the thickness of the bubble wall decreases. In addition, the bubble wall drains outward under the action of the internal and external pressure difference, which also makes the bubble wall thickness gradually decrease. ...
