Tus passivation zaj duab xis nyob rau saum npoo ntawm 304 stainless hlau pluaj kho nrogStainless Hlau Passionationfeem ntau yog lub luag haujlwm tiv thaiv. Txawm li cas los xij, hauv kev siv tiag tiag, muaj ntau yam uas coj mus rau kev rhuav tshem ntawm lub xeev passive, kom lub xeev passive thiab oxidation tsis kam ntawm 304 stainless hlau pluaj, kawg ua rau xeb thiab xeb.
1. Chlorine ions.Chloride ions rau ntawm 304 stainless hlau muaj kev phom sij, txawm tias thaum ua tiav cov ntsiab lus corrosine, yog li thaum ua tiav cov corrosion tsis kam ntawm 304 stainless hlau pluaj.
2. Nto kom huv.304 Stainless hlau pluaj muaj qhov chaw du, nws yog qhov nyuaj rau cov khoom txawv teb chaws mus rau nws, yog li qhov tshwm sim ntawm corrosion yog tsawg kawg nkaus. Txawm li cas los xij, qee qhov chaw yog ntxhib, cov khoom txawv teb chaws tuaj yeem yooj yim txuas rau nws, uas yuav ua rau kev xeb npoo ntawm stainless hlau pluaj.
3. Kev siv cov xov xwm ib puag ncig.304 stainless hlau pluaj deg passivation zaj duab xis los ntawm cov qauv thermodynamic keeb kwm pom, yog inhibited los ntawm cov qauv hloov, cov nyhuv tiv thaiv thiab cov kev tiv thaiv ib puag ncig. Hauv kev siv yuav tsum tau ntxuav tu, uas pab tshem tawm cov teeb meem ua ke txuas rau saum npoo.
4. Cov ntsiab lus ntawm kev siv hluav taws xob ntawm cov hlau stainless hlau nws tus kheejCov. Qee cov hlau stainless hauv qee cov khoom siv tseem yuav muaj kev cuam tshuam rau ntawm nws cov ntsiab lus chromium thiab cov ntsiab lus npib chrom thiab npib nyiaj tsawg, yog tias cov ntsiab lus npib nyiaj Chromium thiab cov neeg npib nyiaj npib tsawg, yog qhov tsis tshua muaj neeg ua haujlwm qis dua. Thiab Martensitic Stainless Hlau Strap thiab Austenitic Stainless Hlau Pluaj piv rau passivation kev ua tau zoo kuj yog neeg pluag.
