Problems solved by technology
Due to the electrostatic shielding effect, the peripheral nozzles are also subjected to a stronger electric field force, and the uneven distribution of the electric field at the tip of a single nozzle will also cause the problem of uneven distribution of the jet on the same nozzle, which will aggravate the thickness of the final product fiber film Problems with unevenness and uneven diameter
In order to solve the problems of uneven thickness of the fiber film and uneven fiber diameter caused by the uneven distribution of the electric field in the above-mentioned electrospinning industrialization process, the present invention proposes an electrospinning multi-nozzle arrangement with uniform electric field distribution and strengthening Device and method

The invention belongs to the technical field of electrostatic spinning, and discloses an electrostatic spinning multi-nozzle arrangement device and method for electric field uniform distribution and reinforcement and application, a rectangular array or a circular array is adopted, the upper end of each spinning nozzle is connected with a splitter plate playing a role in splitting, and the top of the splitter plate is provided with an inlet convenient for a spinning solution or melt to enter; the top end of the spinning nozzle is sleeved with electrode rings, one electrode ring is connected with a first high-voltage electrostatic generator through a wire, an electrode plate is arranged at the position 50 mm-200 mm away from the lower side of the top end of the spinning nozzle and connected with a second high-voltage electrostatic generator through a wire, and the splitter plate is grounded. The induction field intensity of the tips of the spinning nozzles distributed on the inner side is greatly enhanced, the overall electric field distribution uniformity is greatly improved, and the beneficial effects of the method can be proved.
Description
technical field [0001] The invention belongs to the technical field of electrospinning, and in particular relates to an electrospinning multi-nozzle arrangement device, method and application with uniform and enhanced electric field. Background technique [0002] Electrospinning is a method of preparing ultrafine fibers from polymer solutions or melts by using high-voltage static electricity. Because of its simple principle and easy operation, it is considered to be one of the simplest and most effective methods for preparing nanofibers, and has industrial prospects. The working principle of electrospinning is to establish a high-voltage electric field between the nozzle and the collecting plate, so that the nozzle is charged by induction or directly. After the received electric field force exceeds the viscous resistance and surface tension, the polymer melt or solution forms a jet and is sprayed onto the collecting plate, and the jet is cooled and solidified or the solvent ...
