Nrog kev loj hlob ntawm kev tawg ntawm smartphones, e-luam yeeb thiab lwm yam khoom sib txuas, nws tsis tuaj yeem hnov qab tias peb nyob ib puag ncig ntawm lithium roj teeb. Txawm hais tias lawv muaj txiaj ntsig zoo, lawv tseem muaj qhov tsis zoo: qhov kev pheej hmoo ntawm tawg. Raws li kev tshawb fawb tsis ntev los no, ib qho kev daws teeb meem zoo tau pom.
LUB TSEV? Ntxiv ib nplaim taws retardant rau lub roj teeb
seev cev kev kawm luam tawm hnub Friday, Lub Ib Hlis 13 hauv phau ntawv journal Kev Txhawb Kev Tshawb Fawb, ib pab neeg tshawb fawb ntseeg tias lawv tau pom txoj kev kho kom xaus rau cov kev tawg no. Yuav ua li cas? Los ntawm kev ntxiv cov nplaim hluav taws kub hnyiab rau lub roj teeb, cov tshuaj lom neeg uas txwv qhov hluav taws kub ntawm cov khoom, hu ua " triphenylphosphate". Qhov txawv yog pom tseeb nyob rau hauv daim duab hauv qab no, qhov twg peb pom yuav ua li cas lub ntsiab ntawm lub roj teeb ntes hluav taws yam tsis muaj tus kheej-timer (rau sab xis) thiab nrog (mus rau sab laug):
Yog tias cov khoom no tau muab tso ncaj qha rau hauv nruab nrab ntawm lub roj teeb, nws yuav " Cov teebmeem tsis zoo rau kev ua haujlwm", qhia cov kws sau ntawv. Txhawm rau tiv thaiv qhov teeb meem no, lawv muab cov triphenylphosphate tso rau hauv "capsule" (ib hom ntaub thaiv npog ua los ntawm cov polymer tshwj xeeb).
Qhov no muaj qhov tshwj xeeb ntawm kev kaw tag nrho los ntawm cov kua uas cais cov electrodes zoo thiab tsis zoo ntawm lub roj teeb. Tsuas yog tias peb ua kom sov rau ntau tshaj 150 ° C. Ntawm qhov kub no, nws tawg thiab tso tawm cov nplaim hluav taws, uas tuaj yeem tua hluav taws hauv lub roj teeb hauv 0,4 vib nas this.
Thaum kawg, cov kws tshawb fawb ntseeg tias cov txheej txheem no kuj tseem tuaj yeem ua ke rau hauv lwm lub tshuab cia siv lub zog loj. Tab sis lub capsule no tsis tau npaj ua lag luam. Cov kev tshawb fawb yav tom ntej yuav tsum tau xyuas kom meej tias nws tiv thaiv ntau yam teeb meem uas lub roj teeb tuaj yeem raug, xws li kev poob siab lossis kev them nqi tseem ceeb heev thiab tso tawm.
CEEB TOOM TAM SIM NO TXOJ CAI ZOO TSHAJ PLAWS NTAWM EXPLOSIONS
Vaping tsis tas yuav yooj yim rau txhua tus, tshwj xeeb tshaj yog thaum nws los daws qhov teeb meem ntawm cov roj teeb (lossis cov khoom ntim), cov "roj teeb" uas tso cai rau koj cov khoom siv vaping ua haujlwm.

Rau qhov no, peb muab rau koj Nov yog kev qhia ntawm "Li-ion" roj teeb uas muaj los ntawm Pascal Macarty, tus kws tshaj lij vaper hauv thaj teb.
