Stainless hlau muaj peev xwm corrode nyob rau hauv nruab nrab uas muaj acid, alkali thiab ntsev, namely corrosion kuj; Nws kuj muaj peev xwm tiv taus atmospheric oxidation, uas yog, xeb; Txawm li cas los xij, qhov loj ntawm nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg ntawm cov hlau nws tus kheej, cov kev siv thiab hom kev tshaj tawm ib puag ncig. Xws li 304 stainless hlau, nyob rau hauv ib qho chaw qhuav thiab huv si muaj kev tiv thaiv corrosion zoo heev, tab sis thaum tsiv mus rau thaj tsam ntawm ntug dej hiav txwv, nws yuav sai sai xeb hauv hiav txwv pos uas muaj ntsev ntau; 316 khoom muaj kev ua tau zoo. Yog li nyob rau hauv ib puag ncig tsis yog txhua yam stainless hlau tsis tuaj yeem xeb.
Stainless hlau nto tsim ib txheej ntawm nyias nyias thiab muaj zog zoo ruaj khov chromium oxide zaj duab xis, thiab tom qab ntawd tau txais lub peev xwm los tiv thaiv corrosion. Ib zaug rau qee yam, zaj duab xis no tsis tu ncua. Cov pa oxygen atoms nyob rau hauv cov huab cua los yog kua yuav nkag mus ntxiv los yog hlau atoms nyob rau hauv cov hlau yuav txuas ntxiv mus cais tawm, tsim ntawm xoob hlau oxide, hlau nto yuav corroded tas li, stainless hlau tiv thaiv zaj duab xis yuav raug puas tsuaj.
Ntau qhov xwm txheej ntawm stainless hlau corrosion hauv lub neej txhua hnub
Qhov saum npoo ntawm stainless hlau muaj cov plua plav, uas muaj cov khoom sib txuas ntawm lwm cov hlau. Nyob rau hauv cov huab cua ntub, cov dej condensate nruab nrab ntawm qhov txuas thiab cov hlau tsis muaj steel yuav txuas ob mus rau hauv microbattery, yog li ua rau cov tshuaj tiv thaiv electrochemical, cov yeeb yaj kiab tiv thaiv raug puas tsuaj, uas yog hu ua electrochemical corrosion; Qhov saum npoo ntawm stainless hlau adheres rau cov kua txiv hmab txiv ntoo (xws li melons thiab zaub, noodle kua zaub, phlegm, thiab lwm yam), thiab tsim cov organic acids nyob rau hauv cov ntaub ntawv ntawm dej thiab oxygen.
Stainless hlau nto yuav ua raws li cov kua qaub, alkali, ntsev (xws li kho kom zoo nkauj phab ntsa alkali, txiv qaub dej txaws), ua rau hauv zos corrosion; Hauv cov huab cua tsis zoo (xws li cov huab cua uas muaj ntau cov sulfide, carbon oxide thiab nitrogen oxide), sulfuric acid, nitric acid thiab acetic acid yuav tsim thaum ntsib nrog dej condensed, yog li ua rau cov tshuaj corrosion.
Tag nrho cov xwm txheej saum toj no tuaj yeem ua rau cov yeeb yaj kiab tiv thaiv nyob rau saum npoo ntawm stainless hlau thiab ua rau xeb. Yog li ntawd, txhawm rau xyuas kom meej tias cov hlau saum npoo yog ci thiab tsis xeb, peb xav kom cov hlau tsis huv yuav tsum tau ntxuav thiab txhuam kom tshem tawm cov ntawv txuas thiab tshem tawm lwm yam. Lub seaside cheeb tsam yuav tsum siv 316 stainless hlau, 316 cov khoom tuaj yeem tiv taus seawater corrosion; Qee qhov stainless hlau yeeb nkab tshuaj muaj pes tsawg leeg ntawm kev ua lag luam tsis tuaj yeem ua tau raws li cov qauv sib xws, tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm 304 cov khoom, kuj yuav ua rau xeb.
