Air bubble electrostatic spinning device

Abstract

The invention discloses an air bubble electrostatic spinning device, comprising a liquid storage tank, a high-voltage electrostatic generator, an air pump, a receiving pole plate and a temperature control device, wherein the liquid storage tank is arranged into two layers, which are an inner layer and an outer layer, respectively; a sealing space is formed between the inner layer and the outer layer; the sealing space is internally provided with a circulation passage; and the temperature control device is communicated with one end of the circulation passage through a heating pipe and communicated with the other end of the circulation passage through a return pipe. As temperature of a spinning liquid is controlled through the temperature control device, the influence of a temperature factor on an air bubble electrostatic spinning process can be reduced, the production controllability and the production efficiency are improved, and the realization of large scale industrial production of nanofibers is facilitated.

Problems solved by technology

[0003] Studies have shown that in addition to factors such as tip potential, fluid viscosity, electrical conductivity, receiving distance and surface tension, environmental factors including temperature also have a certain impact on the fiber size obtained by air bubble electrospinning, but the existing equipment rarely involves the control of environmental temperature Most of the bubble electrospinning devices do not have temperature adjustment and control devices, the production controllability is poor, it is easy to cause large differences in product quality, and the production efficiency is reduced.
