Description
Technical Field
The invention belongs to the technical field of spraying equipment, and particularly relates to an electronic spraying atomization device.
Background
The electrostatic spraying device mainly comprises a high-voltage generating device, a solution supplying device, a spraying device and a collecting device. The principle is that a static electric field is established between the jet liquid and the receiving device in the high-voltage generator, and when the intensity of the static electric field exceeds a critical value, the polymer solution or melt overcomes the surface tension thereof under the action of the electric field force to form a charged jet flow at the spinneret orifice. The charged stream is bent or whiped at a high speed due to electrostatic repulsion, and is cooled to obtain particles or fibers with diameters ranging from tens of nanometers to several micrometers along with solvent volatilization or melt cooling, and finally falls on a collecting device to form a compact particle cluster or fiber membrane material.
The electrostatic spraying technology can be used for preparing fibers with uniform thickness or particles with uniform particle size. The method has great advantages that the method can directly obtain particles with uniform particle size without an emulsifier on the preparation of micron or nanometer sized particles. However, the biggest limitation is in the preparation speed, the typical capillary tube is used as the spray head, the liquid supply speed is required to be consistent with the speed of the liquid flying to the corresponding electrode overcoming the surface tension, and the typical speed is dozens of microliters to a plurality of milliliters per hour, so that the application of the capillary tube in industrial production is greatly limited.
