Description

technical field [0001] The invention belongs to the technical field of electrostatic spinning and relates to an automatic high-efficiency melt electrostatic spinning device. Background technique [0002] With the heating up of nanotechnology, electrospinning method has become one of the current research hotspots because it can prepare nanoscale fibers. The electrospinning method has been recognized as the simplest and most effective method for preparing nanofibers. At present, more than 30 kinds of polymers have successfully prepared ultrafine fibers through this method, and the smallest diameter reaches tens of nanometers. Regarding the research results of electrospinning, the relevant literature has increased exponentially in recent years. [0003] Electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, the substances split by atomization are not tiny droplets, but tiny jets of polymers, which can run for a long distance and finally...

Problems solved by technology

[0004] Electrospinning devices are widely used in the current spinning industry, but most of them are solution electrospinning, solution electrospinning not only must add solvent, but also the added solvent will cause great pollution to the environment, and It is harmful to human health, and its unstable structure and uneven fiber cause low spinning efficiency. However, melt electrospinning does not need to add any harmful chemicals, which saves energy and protects the environment during the spinning process. At the same time, its structure is stable, The uniformity of the fiber, and there is no automated high-efficiency melt electrospinning device for industry
