背景技术Background technique
静电纺丝是一种特殊的纤维制造工艺，聚合物溶液或熔体在强电场中进行喷射纺丝。在电场作用下，针头处的液滴会由球形变为圆锥形(即“泰勒锥”)，并从圆锥尖端延展得到纤维细丝。这种方式可以生产出纳米级直径的聚合物细丝。Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jet-spun in a strong electric field. Under the action of the electric field, the droplet at the needle will change from a spherical shape to a conical shape (that is, "Taylor cone"), and extend from the tip of the cone to obtain a fiber filament. In this way, polymer filaments with nanoscale diameters can be produced.
现有技术中的喷射装置，多是采用泵压原理进行，但其喷涂液体的流体浓度稳定性欠佳，且在喷涂过程中，溶液容易挥发和凝固，最终会影响静电纺丝得到的产品。Most of the spraying devices in the prior art are based on the principle of pump pressure, but the fluid concentration stability of the spraying liquid is not good, and the solution is easy to volatilize and solidify during the spraying process, which will eventually affect the product obtained by electrospinning.
