Vim tooj liab muaj peev xwm tiv taus corrosion, qhov no kuj yog ib qho tseem ceeb heev rau kev sivcev tooj.Nws tuaj yeem siv tau ib txwm nyob hauv acidic lossis lwm qhov chaw corrosive.Qhov no kuj yog ib qho tseem ceeb heev vim li cas nws tuaj yeem siv rau kev tiv thaiv corrosion hauv ntau qhov kev lag luam.Tsis tas li ntawd, muaj lwm txoj haujlwm zoo heev.Copper muaj peev xwm ua tau zoo heev welding muaj peev xwm thiab yog qhov yooj yim rau cov duab, uas tuaj yeem ua lub luag haujlwm zoo hauv kev tsim khoom.
Ua ntej ntawm tag nrho cov, tooj liab raj tsis tsuas yog muaj cov yam ntxwv ntawm zoo tib yam tooj liab hlab, tab sis kuj muaj zoo heev usability.Kev siv lawv tuaj yeem tiv thaiv ntau yam khoom siv kho tshuab kom tsis txhob raug corroded.Ntxiv mus, cov khoom xyaw hauv cov khoom muaj ntau heev, yog li tus nqi tsis siab heev, nyob rau hauv qhov kev siv tau.Nyob rau hauv txoj kev no, ntau tus neeg siv nws, thiab nws tuaj yeem siv los ua kom tiav cov haujlwm tiv thaiv corrosion zoo heev.
Lub raj tooj liab yog lub teeb hauv qhov hnyav, muaj cov thermal conductivity zoo thiab lub zog siab ntawm qhov kub thiab txias.Nws feem ntau yog siv los tsim cov khoom siv hluav taws xob sib pauv (xws li condensers, thiab lwm yam), thiab tseem siv los sib sau cov kav dej kub qis hauv cov khoom siv oxygen.Cov raj tooj liab uas muaj cov kab me me feem ntau yog siv los thauj cov kua dej siab (xws li lub tshuab lubrication, roj siab tshuab, thiab lwm yam) thiab cov raj ntsuas siab siv los ua cov cuab yeej.
Piv nrog rau cov kav dej tooj liab, qhov tsis zoo ntawm ntau lwm cov khoom siv yeeb nkab yog pom tseeb.Piv txwv li, cov kav dej galvanized steel siv nyob rau hauv cov tsev nyob yav dhau los yog yooj yim heev rau xeb, thiab cov kais dej yuav tig liab doog thiab cov dej ntws yuav ua me me tom qab siv sij hawm luv luv.Kuj tseem muaj qee cov ntaub ntawv uas nws lub zog yuav txo qis ntawm qhov kub thiab txias, uas yuav ua rau muaj kev phom sij tsis zoo thaum siv hauv cov kav dej kub.Txawm li cas los xij, txij li thaum lub melting point ntawm tooj liab yog siab li 1083 degrees, nws cuam tshuam los ntawm qhov kub ntawm cov dej kub system yog qhov tseem ceeb negligible.
