植保用靜電噴霧之霧粒粒徑與工作特性分析

Abstract

傳統人工噴霧因為霧滴容易受風力影響，若是風力稍大就會造成農藥飄散的問題，對人畜造成危害；農藥飄散的影響更甚者，會造成鄰田汙染，傷害其他完好的經濟作物，造成農民損失。另一方面，普通的噴槍進行噴霧常常因為需要多次噴灑才能完全覆蓋作物表面，所以容易造成農藥殘留，使消費者健康受到危害。 隨著科技日新月異，靜電噴槍應運而生。靜電噴槍之主要不同構造為在噴槍口加裝上通電鐵片或者銅片，致使噴出之霧滴帶電。靜電噴霧目前在台灣仍不普及，並且農民對靜電噴槍所知甚少，對其優點也不甚了解，因此本文旨在實測靜電噴槍的工作特性還有其物理性質。 本研究中測試三種不同之常見靜電噴槍，分別是ASABA 麻場 ES1210-LT、e-ジェッター NEO HEAT及ARIMITSU AES-03B。先進行實地實驗，分別對三種噴槍做不同工作高度還有不同工作距離之霧粒飄散測試並將蒐集完的數據建檔，後以影像分析的方法來測量霧粒粒徑和平均覆蓋面積，並利用ImageJ之影像軟體來計算平均大小，最後將數據合併整理歸納，製作成工作建議表，作為研究之總結。

Traditional artificial spray is easy to be affected by wind force. If the wind is slightly larger, it will cause the pesticide to drift, causing harm to humans and animals. Even if the pesticide is scattered, it will cause pollution in neighboring fields and harm other good economic crops which cause farmers’ losses. On the other hand, spraying of a common sprayer often require multiple sprays to covers the crop surface completely , that it is easy to cause pesticide residues and harm the health of consumers. With the development of technology, electrostatic sprayers emerged as time require. The main difference of the electrostatic sprayer is that an iron or copper piece is applied to the sprayer’s mouth, so that the sprayed droplets are charged. Electrostatic spray is still not popular in Taiwan, and farmers know little about electrostatic sprayers, and their advantages are not well understood. Therefore, this paper aims to measure the working characteristics of electrostatic sprayers and their physical properties. Three different common electrostatic spray guns were tested in this study, they are ASABA 麻場 ES1210-LT, e-ジェッター NEO HEAT, and ARIMITSU AES-03B。Firstly, the field experiment was carried out, and the sprayers of different working heights and working distances were respectively tested for the three types of sprayers, and the collected data was archived, and then the particle size and the average coverage area were measured by image analysis method. Image software ImageJ was used to calculate the average size. Finally, the data was merged and summarized, and a work recommendation form was prepared as a summary of the study.
