Tooj liab yog cov hlau uas tau cuam tshuam nrog tib neeg txoj kev loj hlob rau ntau txhiab xyoo thiab ua si yog lub luag haujlwm irreplaces hauv ntau thaj teb. Nws cov khoom tshwj xeeb ua rau nws sawv ntawm ntau cov hlau, thiab nws yog dav siv hauv kev lag luam, lub neej txhua hnub, thiab kev tshawb fawb txhua hnub, thiab kev tshawb fawb txhua hnub, thiab kev tshawb fawb txhua hnub, thiab kev tshawb fawb txhua hnub
Los ntawm lub tswv yim lub cev, tooj liab muaj hluav taws xob hluav taws xob zoo. Cov xeeb ceem no ua rau nws xaiv thawj zaug rau kev tsim cov xov hlau thiab cables hauv kev lag luam hluav taws xob. Txawm hais tias nws yog lub zog kis kab uas cov nroog hla lub nroog Crisscross lossis cov xov hlau me me sab hauv cov cuab yeej siv hluav taws xob, tooj yog qhov tsis tseem ceeb. Ib qho ntxiv, tooj liab kuj muaj cov thermal conductivity. Nws yog feem ntau siv los ua cua sov- Kev ua kom sov xws li kub thiab cua sov hloov cua sov thiab ua kom muaj kev ua haujlwm zoo ntawm cov cuab yeej. Ntxiv mus, tooj liab muaj lub reddish zoo nkauj {6} brown xim thiab tom qab cov khoom siv zoo nkauj, ntxiv ib qho kev sib tw ntawm cov neeg muaj kuab heev rau tib neeg lub neej.
Chemically, tooj liab yog qhov ruaj khov nyob rau hauv ib txwm muaj xwm txheej thiab tsis yooj yim kom hnov mob nrog huab cua thiab dej, uas muab nws zoo corrosion tsis kam. Txawm li cas los xij, hauv qee qhov chaw tshwj xeeb, xws li nyob rau hauv muaj cov muaj kua qaub thiab alkalis, tooj liab kuj tseem yuav ua rau cov tshuaj lom neeg. Cov cuab yeej no nco qab tib neeg kom them sai sai thaum siv cov khoom lag luam tooj liab kom tsis txhob muaj kev poob.
Hais txog cov peev txheej, tooj liab muaj nyob rau hauv xwm feem ntau yog nyob rau hauv daim ntawv ntawm ores. Tomqab kev tsuas, tau txais txiaj ntsig, smelting thiab lwm yam txheej txheem, tooj liab nkag tuaj yeem hloov mus rau hauv tus tooj liab. Nrog kev txhim kho kev kawm txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, smelting tshuab tooj liab kuj tau txhim kho tas li, uas tsis yog txo qhov kev cuam tshuam rau ib puag ncig.
Nyob rau hauv kev teb cov teb, tooj liab tau siv dav. Ntxiv rau cov hluav taws xob thiab cov cua sov tau hais tawm saum toj no, nws tseem yog cov khoom siv tseem ceeb hauv kev tsim khoom ntawm cov cuab yeej siv tshuab, cov kav dej, thiab cov khoom siv tshuaj chees. Piv txwv li, hauv kev lag luam hauv tsheb, tooj liab tau siv rau hauv kev tsim cov tshuab hluav taws xob, cov tshuab hluav taws xob, thiab cov hluav taws xob sib xyaw thiab kev nyab xeeb ntawm cov tsheb. Hauv kev tsim kho kev tsim kho, cov kav dej tooj liab feem ntau yog siv rau cov dej thiab cua sov vim yog lawv lub neej kev pabcuam ntev.
Nyob rau hauv lub neej txhua hnub, cov khoom lag luam tooj liab tseem nyob txhua qhov chaw. Tooj liab hotse, xws li tooj liab tais thiab tooj liab, tsis tsuas yog muaj cov kev thov noj qab haus huv tshwj xeeb. Nws yuav tsum raug sau tseg tias thaum siv cov khoom tooj liab, nws yog qhov tsim nyog yuav tsum ua kom lawv huv kom tsis txhob muaj kev sib txuam ntawm cov av cuam tshuam rau lawv siv. Tsis tas li ntawd, tooj liab kub yog poj niam tau hlub los ntawm ntau tus neeg rau nws cov qauv txawv.
Txawm li cas los xij, nws yuav tsum tau sau tseg tias tseem tooj liab muaj ntau yam zoo, nws cov peev txheej txwv. Yog li ntawd, kev rov ua dua tshiab thiab rov siv tooj liab tau dhau los thiab tseem ceeb dua. Kev ua dua cov neeg tooj liab tsis tuaj yeem tsuas yog txuag cov khoom siv xwb tab sis kuj tseem yuav txo cov kev qias neeg thiab ib puag ncig cov pa paug paug tau los ntawm kev txiav thiab zom. Tam sim no muaj ntau lub teb chaws tau tsim cov txheej txheem tooj liab ua kom tiav, thiab tus nqi rov ua dua tshiab ntawm kev txhim kho tas li.
Hauv kev xaus, tooj liab yog hlau nrog cov khoom siv zoo ntxiv. Nws cov hluav taws xob zoo ua haujlwm, thermal conductivity, corrosion ua kom nws ua qhov zoo nkauj ua rau nws ua lub luag haujlwm tseem ceeb hauv tib neeg. Nrog rau kev nce qib ntawm lub sijhawm, cov neeg yuav txuas ntxiv mus tshawb nrhiav ntau daim ntawv sau npe ntawm tooj liab thiab ua kom zoo dua siv cov khoom siv hlau no. Nyob rau tib lub sijhawm, peb kuj yuav tsum tau txhim kho kev paub txog cov chaw pabcuam kev pab thiab txhawb nqa cov khoom siv tooj liab ntawm tooj liab.
