Vim li cas stainless hlau kuj xeb?
Stainless hlau muaj peev xwm tiv taus atmospheric oxidation - uas yog, xeb kuj, thiab kuj muaj peev xwm corrode nyob rau hauv xov xwm uas muaj acids, alkalis thiab ntsev - uas yog, corrosion kuj.
Txawm li cas los xij, qhov loj ntawm nws lub peev xwm los tiv thaiv corrosion nws txawv nrog cov tshuaj muaj pes tsawg leeg ntawm nws cov hlau nws tus kheej, lub xeev ntawm kev sib nrig sib ntxiv, cov xwm txheej ntawm kev siv thiab hom kev tshaj tawm ib puag ncig.
Piv txwv li, 304 steel yeeb nkab muaj peev xwm tiv thaiv corrosion zoo heev nyob rau hauv qhov chaw qhuav thiab huv si, tab sis yog tias nws tau txav mus rau thaj tsam ntawm ntug dej hiav txwv, nws yuav xeb sai sai hauv hiav txwv pos uas muaj ntsev ntau; thiab 316 steel yeeb nkab qhia tau hais tias zoo.
Yog li ntawd, nws tsis yog txhua yam stainless hlau uas tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.
Cov zaj duab xis nto yog puas nyob rau hauv cov ntaub ntawv hauv qab no:
Nyob rau saum npoo ntawm stainless hlau, hmoov av uas muaj lwm yam hlau ntsiab lus los yog attachments ntawm dissimilar hlau hais. Nyob rau hauv cov huab cua ntub, cov dej condensed nruab nrab ntawm cov ntawv txuas thiab cov hlau tsis muaj steel txuas ob mus rau hauv lub roj teeb micro, uas ua rau muaj cov tshuaj tiv thaiv electrochemical. , tiv thaiv zaj duab xis puas, hu ua electrochemical corrosion.
Qhov saum npoo ntawm stainless hlau adheres rau organic kua txiv. Nyob rau hauv lub xub ntiag ntawm dej thiab oxygen, organic acid yog tsim. Tau ntev, cov organic acid yuav corrode hlau nto.
Qhov saum npoo ntawm stainless hlau adheres rau cov khoom uas muaj acids, alkalis thiab ntsev (xws li alkali dej thiab txiv qaub dej txaws los ntawm cov phab ntsa kho kom zoo nkauj), ua rau lub zos corrosion.
Nyob rau hauv cov huab cua tsis zoo (xws li cov huab cua uas muaj ntau cov sulfide, carbon oxide thiab nitrogen oxide), thaum ntsib cov dej condensed, nws yuav ua kua me me ntawm sulfuric acid, nitric acid thiab acetic acid, ua rau cov tshuaj corrosion.
Txhawm rau kom ntseeg tau tias cov hlau saum npoo tau ci ntsa iab thiab tsis xeb, nws raug nquahu kom:
1. Qhov saum npoo ntawm cov hniav zoo nkauj stainless hlau yuav tsum tau ntxuav thiab txhuam tsis tu ncua kom tshem tawm cov ntawv txuas thiab tshem tawm cov khoom siv sab nraud uas ua rau kev hloov kho.
2. 316 stainless hlau yuav tsum tau siv nyob rau hauv seaside cheeb tsam, uas yuav tiv taus seawater corrosion.
3. Cov tshuaj muaj pes tsawg leeg ntawm qee cov kav hlau stainless ntawm lub khw tsis tuaj yeem ua tau raws li cov qauv hauv tebchaws thiab tsis tuaj yeem ua tau raws li 304 cov khoom siv. Yog li ntawd, nws tseem yuav ua rau xeb, uas yuav tsum tau ua tib zoo xaiv cov khoom los ntawm cov tuam txhab muaj npe nrov.
