Description

technical field [0001] The invention relates to the field of electrostatic spinning, in particular to a centrifugal melt electrostatic spinning device. Background technique [0002] Nanofiber refers to a linear material with a diameter of nanoscale and a large length with a certain aspect ratio. Due to its large specific surface area and special surface effects, nanofibers are widely used in filter materials, life sciences, etc. , protective clothing and nano-sensors and other fields; electrospinning technology is one of the simplest and most effective methods for producing nanofibers. The existing electrospinning technology includes solution electrospinning and melt electrospinning. Among them, melt electrospinning Spinning technology does not have the problems of low yield, low strength, safety and environmental protection caused by the use of solvents, and can prepare some thermoplastic polymer materials without room temperature solvents such as PP, PE and PPS, which has ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a lack of melt electrospinning related equipment on the market. Although there are equipment produced for experimental purposes, these equipment are only assembled in modules and are only used for related research purposes. The production efficiency is low, and, Because of the complex melt electrospinning process, these devices also have the problems of complex structure, large weight and volume, and difficult mobile operation. Moreover, the existing melt electrospinning equipment has low integration, and the control of parameters also has operational problems. Trouble and poor precision, frequent shutdowns are required to replenish spinning materials during the production process, continuous production cannot be achieved, and it is difficult to apply in actual production
