Embodiment Construction

[0017] specific implementation plan

[0018] An embodiment of the invention is figure 1 . The workflow is: after the design, processing, and assembly are completed, such as figure 1 After installation, use the mechanical adjustment device 6 to adjust the distance between the electrospinning head 1 and the receiving device 3 according to different needs, generally 100-250mm, and at the same time, different polymer solutions that need to be configured according to different costs are passed through the feeding system 2 Sent to each electrospinning head 1. Start the high-voltage DC power supply 4 to establish a relatively independent 10-50KV high-voltage electric field between each electrospinning head 1 and the receiving device 3 . At this time, the polarization and charging process of the action of the electrostatic field on the polymer solution, and under the action of the electric field force, a variety of Taylor cones and eruptions form nanofibers that lead to the recei...

Abstract

The invention discloses a system for electrospinning nanofiber from polymer, and relates to spinning, biomedicine, membrane filtering technology, storage battery diaphragms and the like. The system for electrospinning the nanofiber from the polymer -adopts polarized effuser type electrospinning heads with bell mouths and adopts a separate energy storage electric field for each electrospinning head, so that the electrospinning capacity of each electrospinning head is improved by tens even hundreds of times, and each spinning head is ensured to have the relatively independent electric field to radically solve the problem that mutual interference between the spinning heads reduces the silk yield, namely the key problem influencing the silk yield in a common nano-fiber electrospinning device, so that each electrospinning head is effectively ensured to have the stable and independent silk yield; therefore, the difficulty that the yield cannot be increased by the prior common electrospinning technology, is overcome, and production equipment for electrospinning nonafiber from the polymer with commercial value can be designed and manufactured.

Description

technical field [0001] Polymer electrospun nanofibers have extremely attractive applications in many fields, such as textiles, biomedicine, filter membranes, and battery separators. It involves a variety of disciplines: high voltage technology, polymer chemistry and physics, mechanical equipment, electrical control automation, etc. Mainly in the fields of high voltage technology and polymer chemistry and physics. Background technique [0002] Polymer electrospinning technology has been recorded not only in the 1930s but even earlier. Although this project, which has aroused great interest in many fields in the international scientific and technological circles due to nanotechnology, has not developed well in the past few decades, including many patented technologies that have not been seen in the market. commercial effect. This is due to the fact that the biggest problem it faces is that the number of electrospun nanofibers is extremely limited. This is the crux of the f...
