农药静电喷雾技术的发展

Development of Pesticide Electrostatic Spraying Technique

静电微量喷雾是跟随超低容量喷雾技术发展起来的新技术,近年来在植物保护中得到了广泛应用。为此,阐述了静电喷雾技术的研究现状;并对液体雾化、雾滴充电、雾滴输运沉降过程以及雾滴充电效果的测试等几方面研究进展进行了回顾;最后,简要地介绍了国内外研制的静电喷头。

The paper mainly describes the current situation of theoretical research on electrostatic spraying technique, which reviewed the advances of electrostatic spraying in the liquid droplets atomization, droplets charging, droplets transportation and deposition on the targets, as well as droplets charging result testing. The paper also briefly introduces some typical nozzles of electrostatic spraying.
