Kev siv tooj liab hauv kev tsim khoom thiab lub neej

conductivity ntawm tooj liab
Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawmtxhuas-dawb tooj liabyog tias nws muaj cov khoom siv hluav taws xob zoo heev, nrog rau kev ua haujlwm ntawm 58m / (Ω.mm square).Cov cuab yeej no ua rau tooj liab siv dav hauv cov khoom siv hluav taws xob, hluav taws xob, kev sib txuas lus thiab kev lag luam hluav taws xob.Qhov hluav taws xob hluav taws xob siab ntawm tooj liab no muaj feem xyuam rau nws cov qauv atomic: thaum ntau tus neeg tooj liab atoms ua ke rau hauv ib qho tooj liab, lawv cov valence electrons tsis nyob rau hauv cov tooj liab atoms, yog li lawv tuaj yeem txav mus los hauv txhua qhov khoom tooj liab., nws conductivity yog thib ob tsuas yog cov nyiaj.Cov txheej txheem thoob ntiaj teb rau cov khoom siv ntawm tooj liab yog qhov kev sib txuas ntawm tooj liab nrog qhov ntev ntawm 1m thiab qhov hnyav ntawm 1g ntawm 20 ° C raug lees paub tias yog 100%.Tam sim no tooj liab smelting tshuab tau tsim tau tib qib tooj liab nrog ib tug conductivity ntawm 4% mus rau 5% siab tshaj tus qauv thoob ntiaj teb no.
Thermal conductivity ntawm tooj liab
Lwm qhov tseem ceeb ntawm cov hluav taws xob dawb hauv cov tooj liab yog tias nws muaj thermal conductivity siab heev.Nws thermal conductivity yog 386W / (mk), uas yog thib ob tsuas yog nyiaj.Tsis tas li ntawd, tooj liab muaj ntau dua thiab pheej yig dua li kub thiab nyiaj, yog li nws tau ua rau ntau yam khoom xws li cov xov hlau thiab cables, connector terminals, busbars, lead thav duab, thiab lwm yam, uas yog dav siv hauv hluav taws xob thiab hluav taws xob, kev sib txuas lus. thiab kev lag luam hluav taws xob.Tooj liab kuj tseem yog cov khoom siv tseem ceeb rau ntau yam khoom siv hluav taws xob xws li cov khoom siv hluav taws xob sib hloov, condensers, thiab radiators.Nws yog dav siv nyob rau hauv lub hwj chim chaw nres tsheb auxiliary machines, cua txias, tub yees, tsheb dej tso tsheb hlau luam, hnub ci collector daim phiaj, seawater desalination thiab tshuaj, tshuaj kev lag luam., metallurgy thiab lwm yam kev sib hloov cua sov.
Corrosion kuj ntawm tooj liab
Tooj liab muaj qhov zoo corrosion kuj, zoo dua li cov hlau zoo tib yam, thiab zoo dua li txhuas hauv alkaline cua.Qhov muaj peev xwm ntawm tooj liab yog + 0.34V, uas siab dua li ntawm hydrogen, yog li nws yog cov hlau uas muaj peev xwm zoo.Tus nqi corrosion ntawm tooj liab hauv dej tshiab kuj tseem tsawg heev (li 0.05mm / a).Thiab thaum cov kav dej tooj liab tau siv los thauj cov kais dej, cov phab ntsa ntawm cov kav dej tsis tso cov ntxhia, uas nyob deb dhau qhov ncav cuag ntawm cov kav dej hlau.Vim hais tias ntawm no feature, tooj liab kav dej, faucets thiab lwm yam khoom siv lug siv nyob rau hauv advanced chav dej khoom siv.Tooj yog tsis tshua muaj resistant rau atmospheric corrosion, thiab nws muaj peev xwm tsim ib tug tiv thaiv zaj duab xis yog tsim los ntawm yooj yim tooj liab sulfate nyob rau saum npoo, uas yog patina, thiab nws cov tshuaj muaj pes tsawg leeg yog CuS04 * Cu (OH) 2 thiab CuSO4 * 3Cu (OH) 2.Yog li ntawd, tooj liab yog siv rau lub tsev ru tsev panels, cov kav dej nag, cov kav dej sab saud thiab qis, thiab cov yeeb nkab fittings;chemical thiab tshuaj ntim, reactors, lim pulp;cov khoom siv nkoj nkoj, cov kiv cua, lub neej thiab cov yeeb nkab hluav taws xob sib txuas;punched npib (corrosion resistance) ), kho kom zoo nkauj, medals, trophies, sculptures thiab handicrafts (corrosion kuj thiab elegant xim), thiab lwm yam.
