Melt Electrospinning Equipment

Abstract

The invention provides fusion electrostatic spinning equipment. A high-molecular polymer is made to form nanofibers through high-temperature and high-speed air and static electricity. The fusion electrostatic spinning equipment comprises spinning die heads, spinning nozzles, high-voltage power supply devices, a receiving plate, high-pressure gas conveying pipes and spinning die head cover plates. Material conveying chambers are formed among the spinning die heads, the high-pressure gas conveying pipes and the spinning die head cover plates. Protruding ribs are arranged on the outer circumferential walls of the spinning die heads and located inside the material conveying chambers, a plurality of metal conduits communicated with the material conveying chambers and gas conveying channels in the middle parts of the spinning die heads are arranged on the protruding ribs, and primary gas ejector pipe heads are fixedly arranged on the upper portions of the discharging ends of the metal conduits. The spinning nozzles stretch out of the spinning die heads in a downward mode. The receiving plate is located below the spinning nozzles. The high-voltage power supply devices are connected with the metal conduits and the spinning nozzles through high-voltage power lines. By the adoption of the fusion electrostatic spinning equipment, continuous high-efficiency production of micron or nano fibers can be achieved, production efficiency is high, production cost is low, and the requirements for the nano fibers and related products of the nano fibers by mass production, product application and the like can be met.

Description

technical field [0001] The invention belongs to the technical field of nanofiber preparation, and relates to a melting electrospinning equipment for producing nanofibers and nanofibers prepared by the equipment. Background technique [0002] Nanofiber: Refers to a thread-like material with a diameter of nanoscale and a large length with a certain aspect ratio. In addition, fibers that are modified by filling nanoparticles into ordinary fibers are also called nanofibers. In a narrow sense, the diameter of nanofibers is between 1nm and 100nm, but in a broad sense, fibers with a diameter of less than 1000nm are called nanofibers. [0003] Nanofibers have a wide range of uses, such as implanting nanofibers into the surface of the fabric, a stable gas film can be formed to make an amphiphobic interfacial fabric, which can not only waterproof, but also prevent oil and dirt; made of nanofibers Advanced protective clothing, the fabric is porous and has a membrane, which not only al...
