Copper yeeb nkab, tseem hu ua liab tooj liab yeeb nkab, yog ib yam ntawm cov yeeb nkab uas tsis yog-ferrous hlau. Nws yog ib tug nias thiab kos seamless yeeb nkab. Cov yeeb nkab tooj liab muaj cov yam ntxwv ntawm kev ua kom muaj zog thiab tiv taus corrosion, thiab tau dhau los ua thawj qhov kev xaiv rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias kav hauv txhua lub tsev lag luam.
Lub siab tsis kam ntawm cov yeeb nkab tooj liab yog ob peb zaug lossis txawm tias kaum ob lub sijhawm ntawm cov yeeb nkab yas thiab txhuas-yas yeeb nkab. Nws tuaj yeem tiv taus cov dej siab hauv cov tsev niaj hnub no, yog li cov kav dej tooj liab kuj yog cov kav dej.
Ua ntej tshaj plaws, cov yeeb nkab tooj liab muaj cov thermal conductivity zoo heev. Tooj liab yog cov khoom siv thermal conductive zoo heev nrog cov thermal conductivity coefficient ntau dua li ntau lwm cov hlau. Qhov no tso cai rau cov kav tooj liab hloov cov cua sov sai thiab sib npaug, thiab tsim nyog rau kev tsim ntau yam khoom siv hluav taws xob xws li radiators, cua sov exchangers thiab cua txias tshuab. Cov kav dej tooj liab kuj tseem siv tau rau hauv lub tshuab hluav taws xob hnub ci vim lawv tuaj yeem hloov lub hnub ci zog rau hauv thermal zog.
Thib ob, cov kav dej tooj liab muaj qhov zoo corrosion kuj. Cov khoom siv tooj liab tuaj yeem tswj tau zoo corrosion nyob rau hauv feem ntau ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv qhuav huab cua thiab tsis tshua muaj acid thiab alkali ib puag ncig. Qhov no ua rau cov kav dej tooj liab yog qhov kev hloov zoo tshaj plaws rau cov khoom siv hauv cov kav dej ib txwm muaj, uas tuaj yeem ua kom lub sijhawm ntev thiab ruaj khov ntawm cov khoom siv dej. Tsis tas li ntawd, cov raj tooj liab kuj muaj peev xwm tiv taus cov kab mob lom thiab kev loj hlob ntawm microbial, tiv thaiv kev kis kab mob thiab kab mob.
Tsis tas li ntawd, cov raj tooj liab muaj cov yas zoo heev thiab kev ua tiav. Vim tias tooj liab muaj qhov zoo ductility thiab plasticity, nws tuaj yeem tsim los ntawm ntau yam txias thiab kub ua los tsim cov raj tooj liab ntawm cov khoom sib txawv thiab cov duab. Qhov no ua rau cov raj tooj liab tau siv dav hauv ntau yam kev lag luam, xws li engineering machinery manufacturing, tsheb tsim, khoom siv hluav taws xob thiab khoom siv hauv tsev. Cov raj tooj liab kuj tseem tuaj yeem welded, riveted thiab txuas nrog lwm cov ntaub ntawv los pab tsim cov txheej txheem engineering ntau dua.
Tsis tas li ntawd, cov raj tooj liab kuj muaj kev ntseeg tau zoo thiab ua haujlwm ntev. Cov raj tooj liab ua tau zoo nyob rau hauv ib puag ncig xws li qhov kub thiab txias, siab thiab av noo, thiab tuaj yeem tswj kev ruaj ntseg ntawm lawv cov kev ua tau zoo thiab cov qauv nyob rau hauv cov xwm txheej hnyav. Tsis tas li ntawd, cov raj tooj liab kuj tsis yooj yim cuam tshuam los ntawm kev cuam tshuam thiab extrusion, thiab tuaj yeem tiv taus siab sab nraud. Yog li ntawd, cov raj tooj liab muaj lub neej ua haujlwm ntev thiab cov nqi kho mob tsawg.
Thaum kawg, cov raj tooj liab kuj muaj cov tshuaj tua kab mob. Cov kev tshawb fawb tau pom tias tooj liab muaj peev xwm tua tau thiab inhibit cov kab mob loj hlob. Piv nrog rau cov kav dej uas siv cov yas, cov kav dej tooj liab tuaj yeem txo qhov kev loj hlob ntawm cov kab mob thiab cov kab mob hauv cov kav dej, txhim kho cov dej kom zoo thiab tiv thaiv tib neeg kev noj qab haus huv.
