Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm DEET yog tsim kom muaj vaporous barrier nyob ib puag ncig ntawm daim tawv nqaij los ntawm volatilization, uas tuaj yeem cuam tshuam cov induction ntawm volatiles ntawm tib neeg lub cev los ntawm cov tshuaj sensors ntawm yoov tshaj cum, yog li ua rau yoov tshaj cum tsis xis nyob thiab ua rau tib neeg tsis txhob yoov tshaj cum tom.
Cov tshuaj yoov tshaj cum:
Cov tshuaj yoov tshaj cum, tseem hu ua ethyl butyl acetylaminopropionate , IR3535 , thiab Yimening , yog cov yas yas thiab cov broad-spectrum, high-efficiency thiab tsawg-tshuaj tua kab.Cov khoom siv tshuaj lom neeg ntawm cov tshuaj tiv thaiv ester yog qhov ruaj khov thiab tuaj yeem siv rau hauv cov huab cua sib txawv.Nyob rau tib lub sijhawm, nws muaj thermal stability thiab siab tawm hws.Cov yoov tshaj cum kuj tsis muaj zog.
Lub hauv paus ntsiab lus ntawm cov tshuaj yoov tshaj cum yog tias yoov tshaj cum siv lub tshuab olfactory los nrhiav lub hom phiaj nrog cov ntxhiab tsw tawm los ntawm tib neeg lub cev, xws li exhaled gas thiab tsw ntawm daim tawv nqaij, thiab lub luag hauj lwm ntawm yoov tshaj cum yog nyob rau hauv tib neeg lub cev.Qhov saum npoo tsim ib qho kev thaiv, yog li cais cov emission ntawm tib neeg lub cev tsw, ua rau tuag tes tuag taw olfactory system ntawm yoov tshaj cum, thiab cuam tshuam nrog induction ntawm tsw los ntawm yoov tshaj cum, yog li ua tiav cov nyhuv ntawm repelling yoov tshaj cum.
