Dab tsi yog cov khoom tseem ceeb ntawm cov roj luam yeeb hluav taws xob?

Muaj kev sib tham ntxiv txog e-luam yeeb, thiab cov neeg siv khoom feem ntau tsom mus rau lub hom phiaj ntawm e-luam yeeb siv thiab qhov tsw ntawm cov luam yeeb zoo dua rau kev haus luam yeeb. Yog tias koj xav siv nws nrog kev ntseeg siab, koj yuav tsum muaj kev nkag siab zoo ntawm cov roj luam yeeb hluav taws xob. Niaj hnub no, cia peb kawm txog qhov muaj pes tsawg leeg thiab kev ua haujlwm ntawm cov roj luam yeeb nrog Tij Laug David.

Electronic luam yeebroj yog tsim los ntawm plaub yam: glycerol (VG), propylene glycol (PG), spices, thiab nicotine. Nov yog cov lus qhia ntxaws ntxaws txog cov haujlwm ntawm plaub cov khoom xyaw no:

Glycerin (VG)

VG, tseem hu ua VG, yog ib hom tshuaj thiab khoom noj khoom haus uas feem ntau siv los ua cov khoom qab zib xws li ncuav qab zib thiab chocolates. Nws tsis muaj kev phiv rau tib neeg lub cev, tsis muaj xim thiab tsw, thiab yog hygroscopic heev, tab sis viscous. Yog li ntawd, nws me ntsis ua rau qhov nyuaj ntawm kev ntxuav lub atomizer thiab txo cov roj hloov ceev ntawm cov tub ntxhais (kuj yooj yim kom qhuav hlawv / muab tshuaj txhuam). VG tuaj yeem raug rho tawm ncaj qha los ntawm cov roj zaub, txiv maj phaub roj, thiab cov roj xibtes, rhuab mus rau qhov kub thiab txias, thiab tom qab ntawd distilled rau purification. Yog li USP zaub mov qib zaub glycerol siv tsis tu ncuae-luam yeebmuaj purity ntawm 99.7 feem pua ​​thiab 0.3 feem pua ​​dej.

Propylene glycol (PG)

Kuj hu ua PG, nws yog siv los dilute lub viscosity ntawm VG. Hygroscopic, me ntsis qab zib, tsis muaj xim thiab tsw, nrog flowability zoo li dej. Lub US Food and Drug Administration (FDA) piav qhia txog PG li "feem ntau muaj kev nyab xeeb rau tib neeg noj qab haus huv" (xav txog tsuas yog noj) thiab yog ib qho tshuaj thiab khoom noj ntxiv. PG muaj cov roj conductivity zoo thiab ua rau "cov pa luam yeeb me me" thiab "caj pas" zoo ib yam li kev haus luam yeeb.

PG tau raug lees paub los ntawm FDA cov kev tshawb fawb kom raug cais raws li kev nyab xeeb ntxiv (xa mus rau kev noj tshuaj xwb), txawm hais tias nws kuj yog ib qho ntawm cov khoom siv rau kev tiv thaiv kab mob, feem ntau siv hauv kev ua kom tsis muaj zog thiab khoom noj khoom haus thiab dej haus nrog cov kev cai tshwj xeeb. Txawm hais tias PG feem ntau muaj kev nyab xeeb, tseem muaj cov neeg tsawg tsawg uas yuav muaj cov tsos mob ua xua me, xws li caj pas tsis xis nyob, phlegm, kiv taub hau, thiab lwm yam. Cov kev mob tshwm sim no luv luv thiab me me.

Txawm li cas los xij, FDA cov lus tshaj tawm yog qhov tseeb "Kev Pom Zoo Raws Li Kev Nyab Xeeb (GRAS)", uas yog hais txog "kev noj mov". Lwm txoj hauv kev xws li nqus pa, txhaj tshuaj, lossis siv hauv zos tsis nyob hauv thaj tsam ntawm GRAS! Yog li ntawd, kev nyab xeeb ntawm aerosols uas tsim los ntawm cov luam yeeb hluav taws xob tom qab atomizing cov luam yeeb roj tsis yog nyob rau hauv qhov kev lees paub ntawm FDA.

Artificial los yog natural essence

Ntxiv nrog rau kev haus luam yeeb tsw, ntau yam txuj lom uas tuaj yeem siv tau los tsim cov khoom sib txawv thiab ntau yam, xws li txiv hmab txiv ntoo, khoom qab zib, dej haus, thiab lwm yam khoom qab zib.

Nicotine

Nicotine yog ib qho tshuaj tiv thaiv. Piv nrog rau kev haus luam yeeb, cov ntsiab lus nicotine hauv cov roj luam yeeb tau raug lees paub tias nyob rau hauv qhov kev nyab xeeb rau tib neeg noj. Tau kawg, kuj tseem muaj cov roj nicotine tsis pub haus luam yeeb muag hauv khw.
