Abstract

The invention relates to a spraying nozzle device for electrostatic spinning, comprising a spinning liquid flow channel through which spinning liquid passes; the spinning liquid flow channel comprises a liquid inlet and a liquid outlet; the liquid outlet of the spinning liquid flow channel is provided with a flow dividing net in a covering manner; the side of the flow dividing net, which is far from the liquid inlet, is distributed with flow guiding filaments overhanging towards the outer side of the liquid outlet; and at least one of the flow dividing net and the flow guiding filaments is made of a conductor material. As the spraying nozzle device for electrostatic spinning adopts the flow dividing net to replace the traditional spraying head to spray spinning liquid and guides the spinning liquid to flow to form spinning liquid drop by the flow dividing filament instead of adopting the traditional spraying nozzles of spraying pipes, for the net holes compared with the spraying holesof the spraying nozzle, the processing difficulty is greatly reduced, the accuracy is easy to guarantee and the problem that the traditional spinning nozzle is difficult to process is solved; in addition, as the flow guiding filament can lead the spinning liquid flow sprayed from the net holes of the flow dividing net to further be lengthened and fined, finer flow guiding filament can be processed, and specifically, the nano level can be achieved.

Description

technical field [0001] The invention relates to a polymer spinning device, in particular to a nozzle device for electrostatic spinning. 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 worldwide attention. Since 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 substances, air cleaning and filtration, and military affairs. Many fields hav...
