Abstract

The invention discloses a novel centrifugal melt electrostatic spinning device. The device mainly comprises a spinning component, a receiving component, an electromagnetic heating component, a high voltage generating component, a power-driven component and a rack. The spinning component comprises a liquid storage tank, an end cover, first circular cone frustum spray head assemblies and second circular cone frustum spray head assemblies. The receiving component comprises a plastic bottom plate made of nylon and an aluminum receiving plate which can slide on the plastic bottom plate through bolt adjusting, wherein a groove is formed in the plastic bottom plate. The electromagnetic heating component comprises an electromagnetic coil, an electromagnetic control box, an infrared thermometer and supporting rods. The electromagnetic coil is located at the lower end of the liquid storage tank. The high voltage generating component comprises a high voltage generator, wherein a positive electrode of the high voltage generation is connected with the static receiving plate of the receiving component. The power-driven component comprises a motor and a shaft, the shaft is driven by the motor to rotate so as to drive the liquid storage tank to rotate. The rack is grounded and supports the whole spinning system. Centrifugal force is introduced into a traditional melt electrostatic spinning device, by the utilization of dual functions of electrostatic force and centrifugal force, fibers are stretched and refined, and finally nanometer fibers are manufactured in order in batch.

Description

technical field [0001] The invention relates to a novel centrifugal melt electrospinning device, which belongs to the field of electrospinning. Background technique [0002] With the continuous increase of nanotechnology research, the application of nanofibers is becoming more and more extensive. Electrospinning, as a simple and efficient technology for the preparation of continuous nanofibers, has attracted extensive attention from researchers and industries. The basic principle of electrospinning is to use electrostatic force as a pulling force to prepare microfibers. Electrospinning is divided into solution electrospinning and melt electrospinning. Due to a series of disadvantages of solution electrospinning, such as low yield and difficult solvent recovery, melt electrospinning has become a more promising new type of nanofiber production. technology. But so far, melt electrospinning has not been able to produce ordered fibers with diameters less than 500 nm in large q...
