Abstract

The invention relates to a preparation method for an ultrasonic atomization spraying film. A simple ultrasonic atomization device is used for atomizing spraying liquid into ultra-fine liquid drops; the ultra-fine liquid drops are uniformly adhered to the surface of a base material by using external auxiliary airflow, so that a coating of which the thickness is uniform and controllable and the appearance quality is high is formed; the problems that in the prior art, the surface uniformity of a coating is poor, a coating effect is low, spraying amount is not controllable, productivity is low and the like are solved; and the purpose of accurate spraying is achieved. Compared with the prior art, the preparation method for the ultrasonic atomization spraying film has the advantages that spraying efficiency is high, the quality of the film is high, the repeatability of products is high, the liquor using rate is also high, the spraying area and the thickness of the coating can be accurately controlled, and the like.

Description

technical field

[0001] The invention relates to the technical field of spraying, and relates to the spraying processing technology of nano-films, in particular to a novel method for preparing ultrasonically atomized sprayed films. Background technique

[0002] Ultrasonic atomization spraying is a method of thin film preparation, which is used to spray thin films on the surface of substrates. The process generally includes three steps: ultrasonic atomization, spraying, and post-treatment. Ultrasonic atomization is the use of ultrasonic cavitation, so that the tiny cavitation nuclei (bubbles) in the solution oscillate, grow and expand under the action of ultrasonic energy, and migrate to the surface of the solution. After reaching the surface of the solution, they rupture to form tiny droplets (fog) ). Because the droplets of ultrasonic atomization are small in size and uniform in distribution, the atomization effect is good and easy to control, which can avoid many unnecessa...
