Ntau tus neeg xav tias polished stainless hlau kav siv los tiv thaiv qhov rais thiab staircase guardrails tsis yooj yim rau xeb. Nws yog qhov tseeb tsis yog kom nkag siab qhov ntawd. Txawm hais tias nws tau hais tias yog cov kav hlau stainless, xeb tseem yuav tshwm sim. Cov khoom siv stainless hlau yog qhov nyuaj dua. Xeb yog piv rau lwm yam khoom siv hlau, tab sis koj yuav tsum ua li cas thaum cov ntaub ntawv stainless hlau xeb vim kev ua haujlwm tsis raug?
Koj tuaj yeem ntxuav nws nrog dej kais dej, so nrog phuam, lossis nug ib tus neeg uas tuaj yeem ua cov hlau tsis muaj steel rau koj thov kom muaj cov tshuaj tiv thaiv xeb lossis tshuaj tiv thaiv xeb, yog tias koj tsis tuaj yeem mus rau cov tshuaj tiv thaiv xeb, koj yuav tsum nug lawv tam sim ntawd Qhov kev pab cuam lub qhov rooj tuaj yeem pab koj daws nws, tsis txhob' tsis txhob siv xab npum kua lossis xab npum hmoov los daws koj tus kheej.
Nyob rau hauv lub neej niaj hnub, ntshiab chloride ions yuav xeb stainless hlau kav. Lub xub ntiag ntawm chloride ions ntau dua. Cov dej hiav txwv zoo ib yam, noj ntsev, dej hiav txwv txias, cov txheej hauv av, hws cov cim, thiab lwm yam txhua tus muaj cov duab ntxoov ntxoo ntawm cov tshuaj chloride ions, yog li yog tias cov hlau tsis muaj steel, cov yeeb nkab yuav xeb thaum nws khaws cov chloride ion mus ntev. Txhawm rau kom tsis txhob xeb zoo dua, cov yeeb nkab yuav tsum tau txhuam ntau zaus kom cov yeeb nkab huv si thiab qhuav.
Kuj tseem muaj cov kav hlau tsis muaj steel hlau uas tsis muaj cov yeeb nkab steel hlau melting rau hauv cov khoom siv hauv paus, uas yuav ua rau cov aluminium alloy muaj pes tsawg leeg ntawm cov khoom siv hauv paus yuav raug txo, thiab corrosion kuj tsis zoo. Ntxiv titanium thiab niobium rau cov yeeb nkab steel hlau tuaj yeem txo qhov kev ntxhov siab corrosion, hauv huab cua lossis tshuaj lom neeg. Ntawm cov khoom corrosive, lub ntiaj teb zoo nkauj ferritic stainless hlau muaj qhov zoo nkauj thiab zoo corrosion kuj. Stainless hlau phaj nrog chromium tuaj yeem tsim cov yeeb yaj kiab chromium nyias ntawm qhov chaw, uas tuaj yeem thaiv O2 thiab tiv thaiv corrosion.
Rusty steel yeeb nkab yog cov tswv yim stainless hlau ntawv. Kev tiv thaiv xeb kev ua haujlwm ntawm 200 series cov khoom zoo dua. Cov ntawv hlau stainless ntawm 200 series khoom kuj zoo dua. Qhov kev thov dav dav qhov ntsuas kub yog qis dua 650 ℃. 304 stainless hlau phaj muaj zoo stainless hlau corrosion kuj. Thiab zoo corrosion kuj. Rau amphoteric oxides, nws tau txais nyob rau hauv qhov kev xeem: ntawm sodium cyanide uas nws concentration tus nqi yog tsawg dua los yog sib npaug rau 65%, lub 304 stainless hlau phaj muaj zog corrosion kuj, thiab nws muaj zog tiv thaiv alkaline daws thiab feem ntau organics thiab muaj zog oxidants. kuj muaj zoo heev corrosion kuj.
