Stainless hlau muaj peev xwm corrode hauv nruab nrab muaj kua qaub, alkali thiab ntsev, namely corrosion tsis kam; Nws kuj muaj peev xwm tiv taus atmospheric oxidation, uas yog, xeb; Txawm li cas los xij, qhov ntau ntawm nws corrosion tiv taus txawv nrog cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau nws tus kheej, cov xwm txheej ntawm kev siv thiab hom kev tawm tsam ib puag ncig. Xws li 304 stainless hlau, hauv ib puag ncig qhuav thiab huv tau zoo tshaj plaws, tab sis thaum twg tsiv mus rau hauv hiav txwv huab, nws yuav tau xeb sai sai hauv qab ntsev; 316 cov khoom siv muaj kev ua tau zoo. Yog li nyob rau hauv ib puag ncig tsis yog txhua yam ntawm stainless hlau tsis tuaj yeem xeb.
Stainless hlau nto tsim ib txheej ntawm nyias nyias thiab muaj zog ruaj ruaj chromium oxide zaj duab xis, thiab tom qab ntawd tau txais kev tiv thaiv corrosion. Ib zaug rau qee qhov laj thawj, zaj yeeb yaj kiab no tas li. Oxygen atoms hauv cov huab cua lossis kua yuav txuas ntxiv mus rau cov hlau xoob, hlau yuav sib cais tas li, kev tiv thaiv stainless hlau, yuav raug rhuav tshem.
Muaj ntau kis muaj qee kis ntawm stainless hlau corrosion hauv lub neej txhua hnub
Qhov saum npoo ntawm stainless hlau tau nce plua plav, uas muaj cov ntawv txuas ntawm lwm cov hlau. Nyob rau hauv huab cua noo, lub condensate dej nyob nruab nrab ntawm cov ntawv txuas thiab stainless hlau yuav txuas ob lub tswv yim entrochifaty, yog li ua yeeb yaj kiab tiv thaiv, uas yog hu ua electrochemical corrosion; Qhov saum npoo ntawm stainless hlau ua rau cov kua txiv kab ntxwv (xws li cov txiv hmab thiab zaub, noodle kua zaub, thiab lwm yam organic acids nyob rau hauv rooj plaub ntawm dej thiab oxygen.
Stainless hlau nto yuav ua rau cov kua qaub, alkali, xws li phab ntsa hluav taws xob alkali), ua rau muaj kev sib txig hauv zos; Hauv cov huab cua qias neeg (xws li huab cua muaj cov sulfide loj, cov pa roj carbon aus, cov pa roj acid, nitrogen acid yuav ua tau thaum ntsib nrog condensed dej, yog li ua rau tshuaj corrosion.
Tag nrho cov xwm txheej saum toj no yuav ua rau cov yeeb yaj kiab tiv thaiv nyob rau saum npoo ntawm stainless hlau thiab ua rau xeb. Yog li ntawd, txhawm rau kom ntseeg tau tias cov hlau saum npoo av ci thiab tsis muaj xeb, peb pom zoo kom tshem tawm cov ntawv txuas thiab tshem tawm cov ntawv txuas thiab tshem tawm cov ntawv txuas ntxiv thiab tshem tawm cov ntawv txuas ntxiv thiab tshem tawm cov ntawv txuas rau sab nraud. Cov dej hiav txwv dej hiav txwv yuav tsum siv 316 stainless hlau, 316 cov khoom tuaj yeem tawm tsam dej hiav txwv corrosion; Qee tus stainless hlau yeeb nkab tshuaj muaj pes tsawg leeg muaj pes tsawg leeg tsis tuaj yeem ntsib cov qauv sib xws tsis tuaj yeem ua tau raws li 304 cov khoom siv, yuav ua rau muaj xeb.
