Embodiment Construction

[0016] The invention discloses an acid airflow electrospinning device. The material cylinder can rotate clockwise and counterclockwise intermittently around its rotation axis. The rotation of the material cylinder increases the initial velocity of the jet. In the process of stretching by electric field force, the airflow is assisted at the same time to form a jet around the bottom of the jet. Under the action of mechanical external force, the jet converges. The acidic surrounding blower creates a weakly acidic volatile environment for the volatilization of the solvent in the jet, promotes the volatilization of the solvent, enables the jet to achieve a relatively ideal solvent volatilization effect within a short receiving distance, and helps to improve the porosity of the fiber sex.

[0017] Such as figure 1 As shown, the present invention discloses that it includes a barrel 1, a first air blowing conduit 41 extending into the barrel 1 at one end, an electrode 3 extending int...

Abstract

The invention discloses an acid airflow assistant electrostatic spinning device. The device comprises a material bucket, a first blowing duct of which one end stretches into the material bucket, an electrode stretching into the material bucket, an air pump connected to the other end of the first blowing duct, a high-voltage power supply device connected to the electrode, and a hard paper roller which faces the outlet of the material bucket and is used to receive jet flows. Multiple copper wire leads are arranged in parallel and at the equal interval; and a frame is formed through enclosing of the copper wire leads, ends of the copper wire leads are wound and connected together, the other ends are made into a hollow pipe, and a cover-free circular columnar air cylinder is equipped with an inclined air outlet.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an acid airflow assisted electrostatic spinning device. Background technique [0002] In the last ten years, with the rapid development of nanomaterials technology and interdisciplinary fields, electrospinning technology has received extensive attention from researchers. [0003] In traditional electrospinning, under the action of high voltage, the liquid droplets suspended on the needle tip of the syringe overcome their own surface tension to form a charged jet, and the flight trajectory of the jet in the electric field is a three-dimensional "jitter or vibration" of bending instability. Whip". After the solvent volatilizes or solidifies, it is collected on the fiber collector in the form of non-woven fabric. [0004] However, traditional electrospinning has technical problems such as insufficient electric field stretching force, insufficient stretching of the jet, and insuf...
