Nta
Ua ntej, tooj liab raj muaj thermal conductivity zoo heev. Tooj liab yog ib qho zoo heev thermal conductor, nrog thermal conductivity coefficient ntau dua li ntau lwm yam hlau. Qhov no tso cai rau cov raj tooj liab hloov cov cua sov sai thiab sib npaug, ua rau lawv tsim nyog rau kev tsim ntau yam khoom siv hluav taws xob xws li hluav taws xob, hluav taws xob hloov hluav taws xob, thiab cov tshuab cua txias. Cov raj tooj liab kuj tseem siv tau rau hauv lub tshuab hluav taws xob hnub ci vim tias lawv tuaj yeem hloov lub hnub ci zog rau hauv thermal zog.
Thib ob, cov raj 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 raj tooj liab yog qhov zoo tshaj plaws rau cov khoom siv hauv cov kav dej ib txwm siv, kom ntseeg tau tias lub sijhawm ua haujlwm ruaj khov ntawm cov dej xa dej. Tsis tas li ntawd, cov raj tooj liab tuaj yeem 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 ua haujlwm tau zoo. Vim tias tooj liab muaj qhov zoo ductility thiab plasticity, nws tuaj yeem tsim los ntawm ntau yam txias thiab kub ua haujlwm 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 kav dej 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 xwb, cov kav dej tooj liab kuj muaj kev ntseeg tau zoo thiab kav ntev. Cov kav dej 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 tau qhov kev ruaj ntseg ntawm lawv cov kev ua tau zoo thiab cov qauv hauv cov xwm txheej hnyav. Tsis tas li ntawd, cov kav dej tooj liab tsis yooj yim cuam tshuam los ntawm kev cuam tshuam thiab extrusion, thiab tuaj yeem tiv taus siab sab nraud. Yog li ntawd, cov kav dej tooj liab muaj lub neej ua haujlwm ntev dua thiab cov nqi kho mob qis dua.
Thaum kawg, cov kav dej 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.
