Research progress of uniform droplets formation technology
The application of uniform droplets is extensive,and the generation methods are increasingly efficient and controllable.This paper describes the principles of continue ink jet(CIJ)and drop-on-demand(DOD).Based on different pulse force formation principles,the technology for producing uniform droplets can be categorized into piezoelectric mode,electromagnetic vibration mode,magnetic fluid mode,gas pulse actuation mode and laser fluid resonance mode.The principles and technical status of these five modes are analyzed and summarized.Furthermore,this paper summarizes the application status of uniform droplet production technology in electronic packaging,inkjet printing technology,micro 3D printing,and biopharmaceuticals.And it provides a prospect for the development trend of uniform droplet production technology.
