Description

technical field [0001] The invention relates to the field of electrostatic spinning, in particular to a 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 The 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 will be used...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the complexity of the melt electrospinning process, there is a lack of mature melt electrospinning equipment on the market. Most of the melt electrospinning equipment simply realizes the spinning function and is only used for related research purposes. These The weight and volume of the equipment are huge, the integration is low, the mobile operation is difficult, and continuous production operations cannot be realized. The control of parameters such as heating temperature, spinning material flow, spinning voltage, and spinning distance is not accurate, and it is very troublesome and has poor flexibility. , very low practicality
