Raws li peb txhua tus paub, cov yam ntxwv cuam tshuam rau qhov zoo ntawm cov xaim pas nrig tsis muaj dab tsi ntau tshaj li cov khoom siv thiab thev naus laus zis, thiab yam khoom siv twg yog siv nyob rau hauv lub hauv paus ntawm cov hlau pas nrig yog qhov txiav txim siab rau qhov zoo ntawm cov hlua hlau. Feem ntau ntawm lawv yog ua los ntawm tooj liab hlau. Vim li cas lawv siv tooj liab hlau?
1. conductivity ntawm tooj liab
Tooj liab yog cov khoom siv dav siv ntau tshaj plaws, thiab ib qho ntawm cov khoom tseem ceeb tshaj plaws yog nws cov conductivity zoo heev. Tsis tas li ntawd, tooj liab muaj nplua nuj reserves thiab tsim nyog tus nqi ntau tshaj kub thiab nyiaj, yog li nws yog dav siv nyob rau hauv cov xov hlau thiab cables, connector terminals, tsheb npav tuav, txhuas thav ntawv thiab lwm yam khoom.
2. Corrosion kuj ntawm tooj liab
Tooj liab muaj qhov zoo corrosion kuj thiab tsis yooj yim rau oxidize hauv huab cua qhuav. Nyob rau hauv cov huab cua ntub uas muaj cov pa roj carbon dioxide, nws yog ib qho yooj yim los tsim ib txheej ntawm cov tshuaj lom yooj yim tooj liab carbonate (tooj liab ntsuab) rau saum npoo, uas tuaj yeem tiv thaiv tooj liab los ntawm corrosion.
3. Ductility ntawm tooj liab
Txhim kho los ntawm cov tuam txhab tooj liab nrog cov cuab yeej paub tab thiab cov cuab yeej siv siab heev, tooj liab nrog cov ductility zoo heev tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev xaim hluav taws xob. Piv txwv li, ntawm cov thawv sib txuas thiab cov terminals, tooj liab tuaj yeem khoov, twisted thiab rub tsis tau ncab lossis tawg. Rau cov cables loj, stranded tooj liab xaim (kwv yees rau cov khoom siv hlau) feem ntau yog siv. Stranded hlau ua rau lub cable hloov tau yooj yim thiab yuav luag tib yam conductivity li ib leeg stranded (khoom) neeg xyuas pib.
Yog li ntawd, cov xov hlau ua los ntawm cov yam ntxwv ntawm tooj liab yog dav siv hauv kev lag luam hluav taws xob thiab hluav taws xob (xws li fais fab, kab xov tooj thiab network cable). Yog tias cov tooj liab siv rau hauv cov khoom no yog cov khoom zoo, cov khoom no tsis tsuas yog muaj kev ua haujlwm zoo, tab sis kuj muaj lub neej ua haujlwm ntev.
Txawm li cas los xij, txhawm rau muag ntawm tus nqi qis thiab txeeb lub khw, qee qhov kev lag luam tsis zoo yuav txuag tau cov nqi tsim khoom, txiav cov ces kaum ntawm kev ua haujlwm thiab cov khoom siv, siv lwm cov tooj liab xws li tooj liab-clad hlau thiab tooj liab-clad aluminium, los yog cov hlau inch uas tsim. tsis ua raws li tus qauv.
Lub neej ua haujlwm luv luv ntawm cov hlua hlau no yuav ua rau lub teeb liab kis tau tus mob, nce kev cuam tshuam ntawm txoj kev, cov ntaub ntawv xa mus tsis raug, thiab ua rau muaj kev hem thawj rau kev nyab xeeb ntawm tus kheej thiab khoom.
