N n-diethyl-m-tolaja / CAS 134-62-3 / deet

Cov lus piav qhia luv luv:

N, N-diethyl-Meta-Tolajamide, feem ntau yog hu ua DEET, yog ib qho tsis muaj xim daj ua kua daj. Nws muaj ntxhiab tsw ntxhiab tsw ntxhiab. Nws cov qauv tshuaj muaj cov cuab yeej toluene, ob pawg neeg ua thawj coj, thiab ib pawg neeg ua haujlwm rau sawv daws, uas ua rau nws cov tshuaj tua kab. Hauv nws daim ntawv ntshiab, DEET feem ntau yog lo thiab roj.

N, n-diethyl-Meta-Tolaja-tolajide (deet) feem ntau suav hais tias yog soluble hauv cov kuab tshuaj ethanol, acetone, thiab chloroform. Txawm li cas los xij, nws solubility hauv dej yog txwv. Tshwj xeeb, DEET tsuas yog me ntsis soluble hauv dej, lub ntsiab lus nws tsis liam zoo hauv cov kev daws teeb meem aqueous. Cov cuab yeej no yog ib qho ntawm cov laj thawj yog tias nws ua tau zoo li cov tshuaj tua kab, vim nws nyob ntawm daim tawv nqaij thiab tsis yooj yim ntxuav tawm.

Puas yog DEET phom rau tib neeg?

DEET yog cov tshuaj pleev cov tshuaj tua kab uas feem ntau suav tias yog kev nyab xeeb rau tib neeg thaum siv raws li cov khw muag ntawv cov lus qhia. Txawm li cas los xij, muaj qee qhov kev txiav txim siab hais txog nws qhov kev nyab xeeb:

1. Cov tawv nqaij khaus: Qee tus neeg tuaj yeem pom daim tawv nqaij lossis kev ua xua tsis haum thaum siv DEET, tshwj xeeb tshaj yog thaum muaj kev cuam tshuam ntau dua. Nws raug nquahu kom ua ib daim duab xeem ua ntej thov nws ntau yam.

2. Inhalation thiab noj: DEET yuav tsum tsis txhob noj lossis nqus tau. Kev noj DEET tuaj yeem ua rau muaj kev noj qab haus huv loj, thiab nqus tau nws ntau ntau tuaj yeem ua kom muaj teeb meem pa.

3. Lub siab: DEET yog muaj nyob rau ntau qhov ntau, feem ntau yog kwv yees li ntawm 5% rau 100%. Cov kev pab ntau dua muab kev tiv thaiv ntev dua tab sis kuj tseem yuav ua rau cov kev pheej hmoo ntawm daim tawv nqaij khaus. Feem ntau nws pom zoo kom siv cov kev xav tau qis dua rau cov kev tiv thaiv ntev.

4. Cov poj niam cev xeeb tub: DEET tuaj yeem siv rau cov menyuam yaus dua ob lub hlis, tab sis nws yuav tsum tau siv nrog kev ceev faj. Cov poj niam cev xeeb tub thiab cov poj niam mis pub mis yuav tsum sab laj nrog tus kws kho mob yuav tsum siv DEET DEET DACT.

5. Kev txhawj xeeb ib puag ncig: Thaum Deet muaj txiaj ntsig tawm tsam cov kab, muaj kev txhawj xeeb txog nws qhov kev cuam tshuam ib puag ncig, tshwj xeeb hauv cov tsiaj txhu etatic aremotystems.

Ceev faj thaum nkoj n, N-diethyl-m-tolajmide?

Thaum xa xov n, N-diethyl-Meta-Tolaja-tolaja (DEET) Nov yog qee qhov kev ceev faj:

1. Kev tswj xyuas ua raws li: Ua kom ua raws li cov kev cai hauv zos, thiab thoob ntiaj teb cov kev pab cuam ntsig txog kev thauj mus los ntawm cov khoom siv phom sij. DEET tuaj yeem raug cais ua cov tshuaj tiv thaiv kev puas tsuaj nyob ntawm nws cov kev xav thiab cov cai hauv koj txoj cai.

4. Kev ntsuas kub: DEET yuav tsum tau khaws cia thiab xa tawm hauv qhov ntsuas kub kom tiv thaiv kev ua kom tsis txhob muaj tshuaj lom neeg. Zam kev ua kom sov siab.

5. Zam kevcialpatibles: Khaws DEET ntawm cov ntaub ntawv tsis sib xws, xws li oxidizers muaj zog, raws li nws yuav cuam tshuam nrog lawv. Xyuas kom meej tias kev thauj khoom yog pub dawb los ntawm cov tshuaj ntawd.

6. Cov ntaub ntawv: Npaj thiab suav nrog txhua cov ntawv thauj khoom tsim nyog, suav nrog cov ntaub ntawv kev nyab xeeb, cia li muab cov ntaub ntawv qhia txog DEET.

7. Kev kawm: ua kom cov neeg ua haujlwm koom nrog kev cob qhia kev cob qhia hauv kev tuav cov ntaub ntawv muaj kev phom sij thiab paub txog cov kev pheej hmoo cuam tshuam nrog DEET.

8. Cov txheej txheem txheej xwm thaum muaj xwm ceev: muaj cov txheej txheem xwm ceev hauv qhov chaw ua rau nchuav lossis txeej thaum muaj kev thauj mus los. Qhov no suav nrog muaj cov khoom noj thiab cov khoom pab ua ntej npaj tau muaj.

9. Kev thauj khoom hom: sib txawv ntawm kev thauj (huab cua, hiav txwv) tej zaum yuav muaj cov ntaub ntawv txaus ntshai tshwj xeeb. Nco ntsoov ua raws cov lus qhia rau hom kev xaiv ntawm kev thauj.
