Multi-nozzle and spherical surface film-forming electrostatic spinning film production apparatus for hollow circular ring pipe

Abstract

The invention discloses an electrostatic spinning film-forming device used for film-forming between multi-nozzles of a hollow ring pipeline and a spherical surface. N pressure-adjustable thrusters with storage liquid are respectively communicated with corresponding hollow ring pipelines; adjacent hollow ring pipelines are connected with each other by a pipeline connector; adjacent hollow ring pipelines are communicated with each other by an insulated hollow connecting pipe with a switch valve; nozzles are arranged below each hollow ring pipeline in equal space; a power supply is connected with each hollow ring pipeline by a transmission line; and a porous spherical surface film-forming receiver and ground wires thereof are arranged below the hollow ring pipeline. Various spinning solutions are injected through the nozzles after passing by all ring pipelines, and continuous nano-fiber is received by the porous spherical surface receiver, thus forming a spherical surface high-density pore nano-fiber film. The electrostatic spinning film-forming device can produce the porous film material which has different material fiber composite proportion, distribution range, fiber diameter and convenient adjustment of load substance; and the film material needs no secondary processing and can be used for the application in the field of non-complete planar film material.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to an electrospinning film-making device with multiple nozzles in a hollow circular pipe and spherical film formation. Background technique [0002] High-voltage electrospinning is a new technology that uses non-Newtonian fluids to generate jets under high-voltage electric fields to form micro-nano continuous fibers. There are significant differences between electrospinning technology and traditional spinning technology, and it has gradually become a new technology for the preparation and processing of fibers, films, and even three-dimensional tubular and foam materials that has attracted much attention worldwide. Because electrospinning technology can compound a large number of therapeutic drugs, antibacterial substances, functional groups and even living cells into fiber materials, it is widely used in biomedicine, environmental protection, enrichment and recovery of rare and precious ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing electrospinning devices have serious problems in the following aspects: First, in the preparation of multi-material fiber composite membrane materials, the existing technology is to prepare independently prepared films by stacking and compounding them into multi-layer films, or independently Mixing and dissolving various material substances into the same fluid medium to prepare composite materials cannot realize the formation of independent fibers of different materials and evenly overlap and compound each other, and the purpose of independent functions of functional groups of materials with different charging properties cannot be achieved; second, the present Some fiber receivers cannot be prepared with local depressions (or bulges), and the film thickness is uniform, and the size and distribution of through holes in the film are uniform.

Thirdly, the electrospinning membrane material, in which different active substances are compounded by fibers of different materials and exerts their functions independently, is also a challenge to the current spinning technology.
