Abstract

The invention relates to a uniform dispersion type gas flow assisted humidity control system for electrostatic spinning. The uniform dispersion type gas flow assisted humidity control system for electrostatic spinning comprises an gas flow uniform dispersion device and a humidity control device; the gas flow uniform dispersion device mainly comprises a gas storage bin, a gas flow buffering pile, aplurality of rotary shifting pieces and a plurality of radial supporting rods; the gas storage bin mainly comprises a hollow large circular table and a hollow large cylinder which are coaxial, the gas flow buffering pile is located inside the gas storage bin, the shape of the gas flow buffering pile is the same as that of the gas storage bin, the gas flow buffering pile and the gas storage bin are coaxial, the gas flow buffering pile mainly comprises a small circular table and a small cylinder, the rotary shifting pieces are sector-shaped and have the same size, the rotary shifting pieces aredistributed on the end face, which is away from the large circular table, of the large cylinder at equal intervals, and the radial supporting rods are distributed among the adjacent rotary shifting pieces; the humidity control device mainly comprises a control panel, humidity sensors, a humidifier, a dehumidifier and a blowing device; and the humidity sensors are distributed in an electrostatic spinning cabin body. The system provided by the invention can accurately regulate and control the humidity of a spinning environment, and stable flow-in of gas flow can be realized.

Description

technical field [0001] The invention belongs to the technical field of electrospinning, and relates to a uniformly dispersed airflow-assisted humidity control system for electrospinning. Background technique [0002] Electrospinning technology is a method of preparing micro / nano fibers that has emerged rapidly in recent years. It has the advantages of simple manufacturing equipment, good fiber structure adjustability, wide range of spinnable raw materials, strong technical integration, and high product added value. It is widely used in national defense industry, biomedicine, environmental governance, electronic energy and other fields. [0003] During the spinning process of organic solvent system solution, the humidity of the environment will bring about changes in the dielectric constant of the air around the jet, especially affecting its compatibility with the solvent in the jet, which in turn will affect the size of the electric field, so to a large extent Humidity will...
