Lus Cim: Raws li cov neeg siv khoom xav tau ntawm nano particle tuaj yeem muab cov khoom sib txawv.

Khoom ua haujlwm

Melting point 1630 ℃, boiling point ntawm 1800 ℃ .Nws yog ib qho zoo heev pob tshab conductive khoom, thiab nws yog thawj pob tshab conductive khoom yuav tsum tau muab tso rau hauv kev lag luam siv.Nws muaj cov yam ntxwv ntawm kev cuam tshuam infrared tawg, cov nyhuv me me, cov nyhuv quantum loj, cov nyhuv nto thiab macro quantum tunneling nyhuv.

Daim ntawv thov kev taw qhia

SnO2 nano hmoov yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob semiconductor, cov pa hluav taws xob ua los ntawm nws lub siab rhiab heev, dav siv rau kev tshawb nrhiav thiab kev kwv yees ntawm ntau yam combustible gas, ib puag ncig muaj kuab paug, muaj pa roj thiab cov pa phem.Lub ntsuas dej noo raws li SnO2 tau siv rau hauv kev txhim kho ib puag ncig sab hauv tsev, chav ntsuas ntsuas qhov tseeb, tsev qiv ntawv, kos duab tsev cia puav pheej thiab tsev cia puav pheej.

Raws li qhov ntxov tshaj plaws kev lag luam roj sensor, tin oxide gas sensors muaj siab rhiab heev, Cov lus teb ceev ceev, tus nqi qis thiab lwm yam kev ua tau zoo, nws tseem nyob hauv txoj haujlwm tseem ceeb ntawm kev lag luam roj.Nws yog dav siv nyob rau hauv kev tshawb nrhiav ntawm combustible gases xws li natural gas, liquefied petroleum gas, C2H2 thiab H2.Nrog rau kev txhim kho ntawm tib neeg kev ua neej nyob thiab ua kom muaj kev mloog zoo rau ib puag ncig muaj kuab paug, cov khoom tshawb pom ntawm cov pa hluav taws xob tau nthuav dav mus rau CO, H2S, NH3, NO2, NO, SO2 thiab lwm yam pa phem.

Tam sim no, muaj kev xav sib txawv ntawm cov khoom siv roj-sensing mechanism.Cov neeg sawv cev tseem ceeb yog lub zog theem tsim txoj kev xav, qhov chaw ntawm qhov chaw them nqi txheej txheem, cov qauv ciam teb barrier, thiab cov qauv ua haujlwm dual.Ntawm lawv, tus qauv dual muaj nuj nqi tuaj yeem piav qhia qhov loj ntawm cov nplej tam sim no.Yog vim li cas vim li cas cov roj rhiab heev ntawm cov khoom siv tau zoo dua thaum nws raug txo qis dua ib qho txiaj ntsig tseem ceeb.

Cia tej yam kev mob

Cov khoom no yuav tsum tau muab cia rau hauv qhuav, txias thiab sealing ntawm ib puag ncig, tsis tuaj yeem raug rau huab cua, ntxiv rau yuav tsum zam qhov hnyav, raws li kev thauj khoom zoo tib yam.
