Spraying technology is a research area that focuses on the development and optimization of techniques for the application of liquids, powders, or other materials onto surfaces. This can include the use of various spraying methods such as air-assisted, airless, electrostatic, and ultrasonic spraying. Spraying technology is commonly used in industries such as agriculture, automotive, pharmaceuticals, and electronics for applications such as coating, painting, disinfection, and cleaning. Researchers in this field work to enhance the efficiency, precision, and quality of spraying processes, as well as to explore new applications and environmental considerations.
