Problems solved by technology
[0004] In the above-mentioned electrospinning method, the premise of forming a jet from the polymer solution is that the droplets in the shape of a Taylor cone must be formed first, which makes the discharge speed of the polymer solution and the intensity ratio of the electrostatic field limited within a narrow range of values. , which leads to high difficulty in the production of nanofibers and difficult production control
At the same time, using a high-voltage power supply to provide the high-voltage electrostatic field required for spinning will not only increase the production cost, but also cause a large safety hazard in the production process, and a little carelessness will endanger the lives of workers.
Furthermore, the syringe needle or capillary used as the injection function is easily blocked, and only one jet can be produced at a time, and the production efficiency is low

The invention discloses a magnetofluid spinning device which comprises a feeding mechanism and a receiving mechanism. The receiving mechanism is located above the feeding mechanism. The feeding mechanism comprises a fluid storage tank, a gas spraying nozzle arranged at the bottom of the liquid storage tank, and a gas supply source connected with the gas spraying nozzle. A gas spraying hole of thegas spraying nozzle faces upwards. The receiving mechanism comprises a rotating plate located above the liquid storage tank and a driving device for driving the rotating plate to horizontally rotate.A magnet is arranged on the rotating plate. The mode that a high-voltage power supply generates an static electric field in the prior art is replaced with the mode that a permanent magnet generates the magnetic field, the spinning process is safer and more stable, and production cost is lower; the feeding mechanism is prevented from the blockage product, material supply is continuous and smooth, nanofiber sustainable production is ensured, bubbles of the fluid storage tank break in the magnetic field and can form multiple strands of jet flow, and the spinning efficiency is greatly improved.
Description
technical field [0001] The invention relates to a nanofiber preparation device, in particular to a magnetic fluid spinning device. Background technique [0002] Nanofibers refer to fibers with a diameter in the range of nanoscale (1-100nm), which can be divided into polymer nanofibers, inorganic nanofibers and organic / inorganic composite nanofibers according to their composition. Nanofibers have the characteristics of high porosity, large specific surface area, large aspect ratio, high surface energy and activity, and high fiber fineness and uniformity. At the same time, nanofibers also have some special properties of nanomaterials, such as quantum size effects and macroscopic properties. The special electrical, magnetic and optical properties brought about by the quantum tunneling effect. Nanofibers are mainly used in separation and filtration, biological and medical treatment, battery materials, polymer reinforcement, electronic and optical devices, enzymes and catalysis....
