Taw qhia rau Aerosol Insecticides

Aerosol insecticides, tseem hu ua sanitary aerosol insecticides, yog cov khoom uas encapsulate insecticide concentrate thiab propellant nyob rau hauv siab-cov kaus poom resistant, thiab yog txau raws li ib tug pos huab ntawm tshuaj tua kab los ntawm lub valve. Cov micro-particles hu ua aerosols. Cov khoom xyaw tseem ceeb suav nrog cov tshuaj tua kab pyrethroid xws li permethrin, deltamethrin, thiab cypermethrin; Qee cov khoom muaj ethers synergistic. Cov khoom no yog thawj zaug ua tiav hauv Suav teb hauv xyoo 1982. Raws li txoj kev txau, nws tau muab faib ua aerosols thiab tshuaj tsuag, thiab yog tus cwj pwm los ntawm kev txav mus los thiab kev ua tau zoo sai.

Aerosol insecticide cans yog cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tawg thiab yuav tsum tau tiv thaiv los ntawm qhov kub thiab txias. Qee cov khoom muaj kev pheej hmoo ntawm kev tawg vim yog lub siab sab hauv ntau dhau. Tom qab siv, cov tshuaj phem xws li formaldehyde tuaj yeem raug tso tawm; qhov cua raws sij hawm yog tsim nyog tom qab txau. Kev tshuaj xyuas zoo hauv tebchaws tau pom tias qee cov khoom tsis ua raws li cov qauv rau cov khoom xyaw nquag lossis tsis raug cai ntxiv cov tshuaj tua kab ua liaj ua teb xws li deltamethrin. Cov khoom lag luam zoo yuav tsum muaj kev ntsuam xyuas dav dav ntawm cov khoom siv physicochemical, cov teebmeem lom neeg, thiab kev nyab xeeb.

Cov micro-particles tsuag los ntawm cov tshuaj tua kab aerosol hu ua aerosols. Cov tshuaj tsuag tsis siv cov tshuaj tiv thaiv tab sis yog txau manually siv cov cua compressed. Kuj tseem muaj ib hom tshuaj tsuag zoo ib yam li aerosols hu ua "air-extruded sprays," uas yog hu ua "air-extruded sprays" vim hais tias lub propellant tsis ejected ntawm lub kaus mom thaum siv; Hloov chaw, cov concentrate yog extruded li tee los yog streaks. Huab cua-extruded sprays tsis tsim pos huab thiab tsis yog -aerosol-raws li, tab sis lawv cov qauv thiab cov qauv kev khiav hauj lwm zoo ib yam li aerosols.
