Tib neeg ntau tshaj plaws ntawm tooj liab thoob ntiaj teb yog nyob rau hauvDaim Ntawv Siv Hluav Taws Xob-}}} Tshwj xeeb, kev tsim hluav taws xob, hluav taws xob hluav taws xob, thiab faib hluav taws xob ntsig txog kev siv hluav taws xob thiab faib khoom. Qhov kev ua thawj coj no los ntawm Copper txoj kev tsis sib xws ntawm cov hluav taws xob muaj hluav taws xob (thib ob tsuas yog rau ultra {2} Tus nqi nyias nyias), thiab tus txheeb ze tus nqi ({3}} ua hauj lwm zoo.
Cov ntsiab lus tseem ceeb ntawm kev siv rooj plaub no:
Cov Hluav Taws Xob thiab Kev Lag Luam: Cov xov tooj Copper yog cov qauv nyob hauv thaj chaw, ua lag luam, thiab cov tsev muaj kev lag luam rau kev siv lub teeb, khoom siv, thiab tshuab. Lawv qhov hluav taws xob qis tsawg me ntsis lub zog poob thiab kub tsim khoom, txo cov kev pheej hmoo tua hluav taws.
Lub Hwj Huam Saws: High {- voltage Tooj liab Cabps tej hluav taws xob los ntawm fais fab nroj tsuag rau cov nroog thiab cov nroog hla cov chaw deb. Txawm hais tias nrog sawv ntawm txhuas nyob rau hauv qee kab siv ua haujlwm, tooj liab tseem yog qhov tseem ceeb rau kev ua haujlwm hauv av (qhov twg tsis tshua muaj kev cuam tshuam ntu).
Khoom siv hluav taws xob: Tooj yog qhov tseem ceeb rau cov laug cam (raws li cov khoom siv hluav taws xob (hauv cov khoom siv hluav taws xob (thiab roj teeb) {} ion roj teeb siv tooj liab cov neeg sau khoom no).
Nyob rau hauv tag nrho cov ntaub ntawv hluav taws xob rau~ 60% ntawm cov tooj liab thoob ntiaj teb{- deb tshaj lwm qhov kev siv zoo li kev tsim kho (kav dej, vov tsev) lossis kev lag luam tshuab.
Txawm hais tias nws cov versatility, tooj liab tau nthuav tawm cov kev txwv uas txwv nws siv hauv qee qhov xwm txheej:
Kev tsis zoo corrosion tsis kam nyob rau hauv ib puag ncig nyab
Tooj liab tarnishes tau yooj yim nyob rau hauv noo, acidic, lossis salading ntsuab "lossis corrodret sai). Nws yog qhov tsis zoo rau cov ntawv thov seaterwater (piv txwv li cov kav dej hiav txwv) lossis raug cov kua roj muaj zog (piv txwv li cov roj uas zoo li npib tsib caug leej.
Softness thiab tsis muaj zog
Ntsiav ntshiab yog mos mos (brinell hardness ~ 35 HB anealed) thiab muaj lub zog qis (~ 220 mpa anealed). Nws deforms yooj yim nyob rau hauv cov nra hnyav lossis kev sib txhuam, ua rau muaj kev cuam tshuam nrog lub zog, thiab cov hlau) lossis cov roj cig).
Siab thermal expansion
Tooj liab muaj cov coefficient ntawm thermal expansion (~ 16.5 × 10⁻⁶ / degree), txhais tau tias nws nthuav dav nrog qhov ntsuas kub. Qhov no tuaj yeem ua rau cov dej xau hauv cov kav dej los yog kev puas tsuaj rau cov hluav taws xob precised yog tias tsis suav nrog cov nqi sib npaug (piv txwv li no, ib npib tsib 5}}}}}}}}}}}}} Ick hlau alloy).
Kev ntxim nyiam rau hydrogen embrittlement
Thaum rhuab hauv hydrogen {{0 eg} Cov txheej txheem nplua nuj (xws li tooj liab muaj kev sib tsoo), uas yog qhov tshwm sim ua "hydrogenon tau hu ua" hydrogen classing "). This limits its use in high-temperature, hydrogen-exposed applications like some chemical reactors.
Tus nqi txheeb ze thiab muab lub zog volpatility
Thaum pheej yig dua cov hlau zoo li npib tsib xee lossis titanium, tooj liab kim dua txhuas (ib qho kev xaiv hauv hluav taws xob) lossis hlau. Tsis tas li ntawd, cov khoom siv tooj liab tau muaj nyob hauv qee lub tebchaws (piv txwv li, Chile, kev cuam tshuam rau kev cuam tshuam, kev cuam tshuam mining, lossis cov kab mob mining.
Tooj liab cov thoob plaws siv siv cov kav los ntawm nws cov cim, muaj txiaj ntsig zoo:
Tshwj xeeb conduction
Tooj liab muaj qhov hluav taws xob zoo tshaj plaws ntawm cov hlau uas nquag tshaj plaws (tsis suav nyiaj), nrog kev tshaj tawm kev ua haujlwm ntawm ~ 58 ms / m (ntawm 20 degree). Qhov no txo qis zog poob hauv cov hluav taws xob kis tau hluav taws xob {}} tseem ceeb rau cov fais fab nyiaj, xaim, thiab cov khoom siv hluav taws xob ncaj qha rau cov nqi thiab kev ua tau zoo.
Zoo heev Thermal conductivity
Tooj liab lub thermal conductivity (~ 401 w / m · k ntawm 20 degree) nyob deb dua li cov hlau ntau tshaj. Nws tau hloov nrawm nrawm, ua rau nws zoo tagnrho rau cov cua sov (hauv Computers / Electronics), cov tshuab hluav taws xob, thiab kev tswj tshav kub kub yog qhov tseem ceeb.
Kev Ductility High thiab Formaby
Tooj liab yog cov ductile, lub ntsiab lus nws tuaj yeem kos rau hauv ultra {{mm) lossis bent, stamped, stamped rau hauv cov duab uas tsis muaj kev tawg. Cov versatility no tso cai rau nws tsim mus rau ntau yam khoom, los ntawm cov board circuit Court board tau cov kav dej loj.
Biocompatibility
Tooj liab yog biologically inert thiab tsis - lom rau tib neeg, ua kom haum rau kev siv tshuaj kho mob. Nws yog siv rau hauv kev phais cov cuab yeej, cog cov khoom siv (piv txwv li cov khoom siv tshuaj tua kab mob), tooj liab alloys tua kab mob zoo li E. coli thiab MRSA txo tus kab mob hauv tsev kho mob).
Siab dua
Tooj liab yog 100% siv dua tshiab yam tsis tau poob nws cov khoom. Rov qab siv cov tooj liab tsuas yog ~ 10% ntawm lub zog uas yuav tsum muaj rau kuv thiab kho tooj liab tshiab, txo cov roj carbon monissions thiab ib puag ncig. Kwv yees li 35% ntawm cov tooj liab tooj liab kev thov tau ntsib los ntawm kev siv tooj liab, txhawb nqa kev tsim khoom ruaj khov.
