Dab tsi yog qhov txawv ntawm cov yeeb nkab steel thiab cov yeeb nkab dub?
Taw qhia:
Cov yeeb nkab steel yog ib qho ntawm cov khoom siv feem ntau siv hauv ntau qhov kev lag luam rau ntau yam kev siv. Lawv paub txog lawv lub zog, durability, thiab versatility. Txawm li cas los xij, thaum nws los txog rau kev xaiv cov yeeb nkab steel tsim nyog rau ib qhov project tshwj xeeb, muaj ntau ntau yam los xav txog. Ib qho kev sib txawv ntawm cov kav hlau tsis tu ncua thiab cov kav hlau dub. Txawm hais tias ob qho tib si ua haujlwm zoo sib xws, muaj qhov sib txawv tseem ceeb ntawm lawv nyob rau hauv cov nqe lus ntawm kev muaj pes tsawg leeg, tsos, kev siv, thiab corrosion kuj. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv qhov kev xaiv tsim nyog tshaj plaws rau ib qhov project. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov sib txawv ntawm cov yeeb nkab steel thiab cov yeeb nkab dub hauv kev nthuav dav, tso lub teeb ntawm lawv cov yam ntxwv thiab kev siv.
Kev sib xyaw:
Cov kav hlau tsis tu ncua, tseem hu ua carbon steel kav, feem ntau yog ua los ntawm hlau thiab carbon. Hlau ua raws li cov khoom siv hauv paus, thaum cov pa roj carbon ntxiv rau ntau qhov sib txawv los txhim kho cov yeeb nkab cov khoom xws li lub zog thiab hardness. Cov ntsiab lus carbon hauv cov kav hlau tsis tu ncua feem ntau qis, feem ntau yog li ntawm {{0}}.06% mus rau 0.25%.
Ntawm qhov tod tes, cov kav hlau dub yog ib hom carbon steel yeeb nkab uas dhau los ua cov txheej txheem tsim tshwj xeeb los faib cov xim oxide tsaus nti ntawm nws qhov chaw. Qhov no oxide nplai, hu ua dub nplai, yog tsim los ntawm cov txheej txheem ntawm blackening. Nws muab cov txheej txheem tiv thaiv corrosion, uas yog vim li cas cov kav hlau dub feem ntau siv rau hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion.
Qhov tsos:
Ib qho ntawm qhov pom kev sib txawv tshaj plaws ntawm cov kav hlau tsis tu ncua thiab cov kav hlau dub yog lawv cov tsos. Cov kav hlau tsis tu ncua muaj cov nyiaj-grey xim hlau zoo li, zoo li cov khoom siv hlau. Txawm li cas los xij, cov kav hlau dub muaj cov xim dub sib txawv vim muaj cov xim dub oxide txheej ntawm lawv qhov chaw.
Cov tsos ntawm cov yeeb nkab dub dub yog tshwm sim los ntawm cov txheej txheem tsim khoom uas lawv tau dhau los, uas cuam tshuam nrog kev tso dej ntawm cov kav dej hauv kev daws teeb meem uas ua rau kev txhim kho cov txheej txheem oxide. Cov txheej txheem no qhia txog qhov tshwj xeeb zoo nkauj ntawm cov kav hlau dub, ua rau lawv pom qhov txawv ntawm cov kav hlau tsis tu ncua.
Daim ntawv thov:
Cov kav hlau tsis tu ncua yog dav siv nyob rau hauv ntau yam kev lag luam thiab kev siv vim lawv lub zog muaj zog thiab kav ntev. Lawv feem ntau ua haujlwm hauv cov kav dej, cov roj thiab roj tsheb thauj mus los, kev faib dej, kev txhawb nqa cov qauv, thiab ua cov casings rau hauv av cables. Cov kav hlau tsis tu ncua pom kev siv dav hauv ib puag ncig uas tiv thaiv corrosion tsis yog qhov kev txhawj xeeb tseem ceeb.
Hauv qhov sib piv, cov kav hlau dub tshwj xeeb yog siv rau hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion. Cov nplai oxide dub ua raws li cov txheej txheem tiv thaiv, tiv thaiv cov khoom siv hlau los ntawm kev sib cuag ncaj qha nrog cov neeg ua haujlwm corrosive. Yog li ntawd, cov kav hlau dub feem ntau yog siv hauv kev lag luam xws li kev kho dej, kev ua tshuaj lom neeg, petrochemicals, cov kav dej phwj tuaj, thiab cov ntawv siv hauv av uas muaj kev sib cuag nrog cov dej noo thiab corrosive.
Corrosion Resistance:
Kev tiv thaiv corrosion yog qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov kav hlau tsis tu ncua thiab cov kav hlau dub. Cov kav hlau tsis tu ncua, tsis muaj cov txheej txheem tshwj xeeb lossis kev kho mob, muaj kev cuam tshuam rau corrosion thaum raug rau qee qhov chaw, tshwj xeeb tshaj yog cov uas muaj cov dej noo ntau lossis cov khoom corrosive. Nyob rau tib lub sijhawm, lawv tuaj yeem tsim xeb, cuam tshuam lawv cov qauv kev ncaj ncees thiab kev ua haujlwm tag nrho.
Cov kav hlau dub, ntawm qhov tod tes, nthuav tawm kev txhim kho corrosion vim muaj cov xim dub oxide. Cov oxide txheej no ua raws li kev thaiv, tiv thaiv cov hlau hauv qab los ntawm cov neeg ua haujlwm corrosion. Yog li ntawd, cov kav hlau dub yog qhov zoo dua rau cov ntawv thov hauv ib puag ncig corrosive lossis cov uas cuam tshuam ncaj qha nrog dej lossis tshuaj lom neeg.
Xaus:
Hauv kev xaus, qhov sib txawv ntawm cov kav hlau tsis tu ncua thiab cov kav hlau dub yog nyob rau hauv lawv cov muaj pes tsawg leeg, zoo li, kev siv, thiab corrosion kuj. Cov kav hlau tsis tu ncua feem ntau yog ua los ntawm hlau thiab carbon, muab lub zog siab thiab ua haujlwm ntev. Lawv muaj ib tug silver-grey metallic tsos thiab nrhiav kev siv nyob rau hauv ntau yam lag luam. Hauv qhov sib piv, cov kav hlau dub dub muaj qhov muag pom vim muaj cov txheej txheem tiv thaiv oxide tsim los ntawm cov txheej txheem blackening. Lawv tshwj xeeb yog siv nyob rau hauv ib puag ncig uas corrosion kuj tseem ceeb heev. Cov txheej txheej dub oxide tiv thaiv cov khoom siv hlau hauv qab los ntawm corrosive los ntawm ya raws thiab tshuaj. Kev nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv cov yeeb nkab steel tsim nyog rau ib qhov project tshwj xeeb.
