超低容量(ULV)喷雾技术近年来已在试用,但尚缺乏一种轻便、耐用的手动喷雾器。因此,我们同崇明电器三厂等单位协作,参考国外有关技术资料,改制成功小型国产手动喷雾器,并对雾化性能等方面进行了初步试验,结果如下。 (一)材料和方法国产翼龙牌PS-03手动喷雾器(下称国产喷雾器)三只;日产ARS手动喷雾器(下称日产喷雾器)三只,以及采样垫子、采样筒、三线油、目、物镜测微尺、铜板纸等。在室温24～26℃,相对湿度76～78％条件下进行试验。喷距、喷幅测定:喷头离地面0.5米。于喷头前及左右侧地面上,每隔0.1米置一张铜板纸。喷雾红墨水4次,10分钟后用放大镜观察结果。粒普测定:喷头离地面1米,干喷头前0.5、
Ultra-low-volume (ULV) spray technology has been tried out in recent years, but there is a lack of a lightweight, durable manual sprayer. Therefore, in collaboration with the third unit of Chongming Electric Appliance Co., Ltd. and other units, we made reference to the relevant foreign technical materials and restructured the successful small-sized domestic hand-operated atomizers. The preliminary tests on the atomization performance were carried out. The results are as follows. (A) materials and methods Domestic pterosaurs PS-03 manual sprayer (hereinafter referred to as domestic sprayer) three; Nissan ARS manual sprayer (hereinafter referred to as Nissan sprayer) three, as well as sampling mat, sampling cylinder, Measuring micrometer, copper paper and so on. At room temperature 24 ~ 26 ℃, relative humidity 76 ~ 78% under the conditions of the test. Spraying distance, spray width Determination: Nozzle 0.5 meters from the ground. In the nozzle before and on the left and right sides of the ground, every 0.1 meters to set a copperplate paper. Spray red ink 4 times, 10 minutes later with a magnifying glass to observe the results. Granule determination: the nozzle from the ground 1 m, 0.5 before the dry nozzle,
