几种气溶胶杀虫器械雾化性能的比较研究

本文对4种冷、热雾杀虫器械的雾化性能进行了室内比较研究。结果发现:(1)热雾机型3Y—1型,转笼式超低容量喷雾器WS—1型,雾化性能较好,雾滴均勻,为较好机种。(2)雾滴NMD、VMD,雾滴密度随喷雾距离增加逐渐降低,雾化均匀的机种降低较慢,雾化不均匀的机种降低较快,有离心风力的机型降低较慢,旦各距离密度较均匀,反之则否。(3)冷、热雾雾滴对蚊笼穿透力不同(P<0.01),热雾对蚊笼穿透力较强,推测其在郁闭程度高的地点使用是有利的。

Comparison Study of Atomizing Performance of Several Insecticide Aerosol Sprayers

The comparison study of atomizing performance of four types of cold and thermal fog sprayers had been done in laboratory.The results showed:(1)The thermal fog sprayer3Y-1 and untralow volume sprayer-WS-1 with even aerosol droplets are well atomizing machines.(2)NMD VMD and depesit density of droplet declined along with the increase of spraying distance.The droplets sprayed out by well atomizing sprayers fall down slower than by poor atomizing sprayers.The droplets sprayed out by sprayers with air-pump drop down slower than by those without air-pump,and the depesit density of droplet was well-distributed.(3)The penetration through the mosquito cages between cold aerosol and thermal fog is different(P<0.05).The thermal fog can penetrate the cages easier than cold aerosol.So that it is available for using in denoely wooded areas.
