Tooj liab, ua ib yam hlau uas tsis yog hlau muaj nqis, tau koom nrog tob rau hauv cov txheej txheem ntawm tib neeg kev vam meej txij li thaum ub los. Niaj hnub no, nyob rau hauv lub sijhawm ntawm kev txhim kho thev naus laus zis sai, tooj liab thiab nws cov hlau txuas ntxiv ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam nrog lawv cov kev ua tau zoo heev. Hauv cov khoom tooj liab, tooj liab liab thiab tooj dag tau siv dav hauv ntau qhov chaw vim lawv cov kev ua tau zoo thiab cov yam ntxwv tshwj xeeb. Kev nkag siab tob txog qhov sib txawv ntawm ob qho, cov xwm txheej thov thiab kev txiav txim siab yuav khoom tuaj yeem pab cov tuam txhab txiav txim siab zoo tshaj plaws hauv ntau qhov xwm txheej.
Qhov Txawv Tseem Ceeb Ntawm Tooj Liab Thiab Tooj Liab
Kev sau ua ke
Tooj liab, uas yog, tooj liab ntshiab, feem ntau muaj cov tooj liab ntau dua 99.5%. Kev ntshiab siab ua rau tooj liab muaj hluav taws xob zoo heev thiab thermal conductivity, ua rau nws yog tib qho kev xaiv hauv kev ua hluav taws xob thiab thermal conductivity. Tooj dag yog ib qho tooj liab-zinc alloy, thiab qhov sib piv ntawm zinc ntxiv ncaj qha txiav txim siab nws cov yam ntxwv. Tooj dag feem ntau muaj li 30% zinc. Kev ntxiv zinc tsis yog tsuas yog hloov cov xim qub ntawm tooj liab xwb, tab sis kuj tseem txhim kho lub zog thiab kev tiv thaiv corrosion ntawm cov khoom.
Qhov tsos thiab xim
Vim nws muaj cov khoom ntshiab heev, tooj liab muaj xim liab-ntsuab ci ntsa iab nrog xim sov so. Raws li lub sijhawm dhau mus, yuav muaj ib zaj duab xis oxide tshwj xeeb rau ntawm qhov chaw, ntxiv cov qauv rustic. Vim yog cov zinc, tooj liab muaj xim kub ci ntsa iab, uas yog qhov muag pom ntau dua thiab nyiam heev hauv kev kho kom zoo nkauj.
Cov Khoom Siv Lub Cev
Hais txog qhov nyuaj, tooj dag feem ntau nyuaj dua tooj liab vim yog kev sib xyaw ua ke thiab tuaj yeem tiv taus kev ntxhov siab ntau dua. Tooj liab muaj kev ywj pheej zoo heev thiab ductility, thiab yooj yim rau kev ua cov duab nyuaj xws li filaments thiab cov ntawv nyias nyias. Hais txog kev ua hluav taws xob thiab thermal conductivity, tooj liab zoo dua vim nws qhov purity siab thiab yog cov khoom siv nyiam rau kev tsim cov xov hlau, cables, thiab cov khoom siv hloov pauv cua sov.
Cov Ntawv Thov ntawm Tooj Liab thiab Tooj Liab
Kev siv tooj liab
Lub teb hluav taws xobQhov ua tau hluav taws xob zoo heev ntawm tooj liab ua rau nws yog cov khoom siv tseem ceeb rau kev tsim cov xov hlau thiab cov cables. Txij li cov kab hluav taws xob siab mus rau cov xov hlau sab hauv tsev, tooj liab ua kom muaj kev xa hluav taws xob zoo thiab txo qhov poob hluav taws xob. Hauv cov khoom siv hluav taws xob tseem ceeb xws li transformers thiab motors, kev siv cov xov tooj liab tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv thiab kev ua haujlwm zoo.
Lub tshav kub conduction tebCov khoom siv hluav taws xob tooj liab ua rau nws tsis tseem ceeb hauv cov khoom siv hloov cua sov, cov tshuab cua sov thiab lwm yam khoom siv. Cov tshuab cua sov ntawm lub cav tsheb thiab cov tshuab cua txias siv cov khoom siv tooj liab los ua kom muaj kev hloov cua sov zoo thiab xyuas kom cov khoom siv ua haujlwm ruaj khov.
Kev siv tooj dag
Kev tsim khoom siv tshuabCov khoom siv kho tshuab zoo ntawm tooj dag ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim ntau yam khoom siv kho tshuab. Txij li cov txiv ntoo thiab bolts mus rau iav thiab bushings, cov khoom siv tooj dag ua lub luag haujlwm tseem ceeb hauv cov tshuab kis tau tus mob. Nws txoj kev tiv thaiv kev hnav thiab kev tiv thaiv corrosion ua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv mus sij hawm ntev.
Kho kom zoo nkauj teb: Cov xim kub ci ntsa iab thiab kev ua haujlwm zoo ntawm tooj dag ua rau nws nyiam hauv kev lag luam kho kom zoo nkauj. Cov tes tuav qhov rooj, teeb, cov kab dai kom zoo nkauj hauv kev kho kom zoo nkauj hauv tsev, nrog rau kev tsim cov duab kos duab thiab khoom siv tes ua, tooj dag tuaj yeem qhia nws lub ntxim nyiam tshwj xeeb.
Cov Kev Ceev Faj Thaum Yuav Tooj Liab Thiab Tooj Liab
Paub meej tias qhov purity ntawm cov khoom siv
Thaum yuav tooj liab, nco ntsoov xyuas kom meej tias qhov huv ntawm tooj liab ua tau raws li qhov yuav tsum tau ua kom tsis txhob muaj cov khoom tsis huv ntau dhau uas cuam tshuam rau kev ua haujlwm. Rau tooj dag, cov ntsiab lus zinc yuav tsum tau ua kom meej. Tooj dag uas muaj cov ntsiab lus zinc sib txawv muaj qhov sib txawv ntawm kev ua haujlwm thiab tus nqi. Nws raug pom zoo kom nug tus neeg muag khoom kom tau daim ntawv pov thawj khoom siv lossis ua kev sim tshaj lij kom ntseeg tau tias cov khoom siv yuav zoo.
Soj ntsuam qhov zoo ntawm qhov tsos
Ua tib zoo xyuas seb qhov chaw ntawm cov khoom puas tiaj tus thiab du, thiab seb puas muaj qhov tsis zoo xws li tawg thiab xuab zeb. Qhov chaw ntawm tooj liab yuav tsum yog xim liab-liab sib npaug, thiab xim ntawm tooj dag yuav tsum sib xws. Rau cov chaw uas muaj kev xav tau tshwj xeeb xws li kev kho kom zoo nkauj, xim ntawm qhov chaw thiab qhov ci ntsa iab yog qhov tseem ceeb.
Muab qhov tseem ceeb rau cov neeg muag khoom uas muaj npe nrov thiab muaj kev paub dhau los, thiab nkag siab tob txog lawv cov txheej txheem tsim khoom thiab kev tswj xyuas zoo. Koj tuaj yeem soj ntsuam qhov zoo ntawm cov khoom thiab qib kev pabcuam ntawm tus neeg muag khoom los ntawm kev kuaj xyuas daim ntawv pov thawj kev tsim nyog ntawm tus neeg muag khoom, kev ntsuam xyuas cov neeg siv khoom, thiab lwm yam. Peb lub tuam txhab cog lus tias yuav muab cov khoom tooj liab thiab tooj dag zoo rau cov neeg siv khoom thiab cov kev pabcuam tshaj lij, pab koj nkag siab txog lawv qhov sib txawv, cov xwm txheej siv thiab cov ntsiab lus yuav khoom, thiab pab koj ua si tag nrho rau lawv cov txiaj ntsig thiab ua tau raws li ntau yam kev xav tau. Txawm hais tias nyob rau hauv kev tsim khoom lag luam lossis lub neej txhua hnub, kev xaiv thiab siv cov khoom siv tooj liab kom raug yuav tsim kom muaj txiaj ntsig ntau dua rau koj.
