静电喷粉沉积性能实验研究

Experimental Research on the Deposition of Electrostatic Dusting

荷电颗粒在作物上的沉积效果是评价静电喷粉性能的主要指标之一．笔者在分析静电场力对荷电颗粒运动影响的基础上，通过风洞和应用改进的喷粉机对模拟目标物进行了沉积实验，结果发现荷电颗粒比非荷电颗粒的沉积量提高１０％以上．

The deposition efficiency of charged particles on plant is one of the main index to evaluate the performance of electrostatic dusting. Based on the effect analysis of electrostatic force on the motion of charged particle, the deposition tests on targets in wind tunnel and with improved electrostatc duster are carried out respectively in this paper and result shows that the amount of deposition of charged particles is 10% more than that of the uncharged ones.
