Description

technical field [0001] The invention belongs to the technical field of liquid atomization, and in particular relates to a mesh microstructure for high-viscosity liquid atomization and a manufacturing method thereof. Background technique [0002] The mesh microstructure used for high-viscosity liquid atomization is a spray device that drives the mesh sheet to vibrate through the vibration of the piezoelectric sheet, contacts the liquid, and drives the liquid to spray. Among them, the mesh diameter of the liquid outlet surface on the vibrating mesh sheet is a key factor determining the diameter of the atomized droplet, and the microstructure of the mesh is one of the factors determining the viscosity of the atomized liquid. At present, the methods of realizing vibrating mesh microstructure in the industry are mainly laser ablation, chemical etching or electroforming technology. The aperture, shape requirements and material selection of the atomizing mesh are greatly restricted...
