Yuav ua li cas yog stainless hlau hluav taws xob cua sov kav hlau xeb

Nyob rau hauv peb niaj hnub siv stainless hlau hluav taws xob cua sov kav, peb qee zaus pom cov xim av xeb ntawm lawv, feem ntau hu ua xeb. Peb xav tias peb tau dag thaum lub sijhawm kev yuav khoom. Qhov tseeb, yog tias koj tshawb hauv online lossis muaj qee yam kev nkag siab ntawm stainless hlau hluav taws xob cua sov kav, koj yuav ua siab ntev txog tej yam zoo li no. Lub npe stainless hlau suab zoo, tab sis cov khoom feem ntau txheeb ze tsis yog qhov tseeb. Tam sim no, tsis muaj qib steel uas tiv taus corrosion hauv ib puag ncig, ob qho tib si hauv tsev thiab txawv teb chaws. Kev tiv thaiv corrosion thiab tsis xeb kuj ntawm stainless hlau hluav taws xob cua sov kav yuav raug rau tej yam kev mob. Thaum lub corrosion kuj ntawm stainless hlau hluav taws xob cua sov kav mus txog, lawv yuav corrode thiab ces xeb. Niaj hnub no peb yuav tham txog qhov ua rau corrosion nyob rau hauv stainless hlau hluav taws xob cua sov kav thiab yuav ua li cas nrog cov xeb me ntsis rau lawv?

Yog vim li cas rau corrosion ntawm hluav taws xob cua sov raj

Stainless hlau kuj tuaj yeem xeb nyob rau hauv qee yam mob. Stainless hlau muaj peev xwm tiv taus atmospheric oxidation, uas yog xeb kuj, thiab kuj muaj peev xwm tiv thaiv corrosion nyob rau hauv xov xwm uas muaj acids, alkalis, thiab ntsev, uas yog corrosion kuj. Tab sis nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg, kev sib nrig sib lub xeev, kev siv tej yam kev mob, thiab hom ntawm ib puag ncig nruab nrab ntawm cov hlau nws tus kheej. Thaum raug cov tshuaj chlorine los yog hnyav ib puag ncig, tshwj xeeb tshaj yog thaum cov txheej txheem passivation ntawm nws qhov chaw yog mechanically lossis chemically puas, nws yog feem ntau xeb dua li niaj zaus. Piv txwv li, 304 steel kav muaj cov xeb zoo heev nyob rau hauv qhov chaw qhuav thiab huv si, tab sis thaum tsiv mus rau thaj chaw ntug dej hiav txwv, lawv sai sai xeb hauv hiav txwv huab cua uas muaj cov ntsev ntau; Txawm li cas los xij, 316 steel kav ua tau zoo. Yog li ntawd, tsis yog txhua hom stainless hlau tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.

(Kev sib txuas: Cov hlau tsis muaj zog corrosion kuj txo qis nrog qhov nce ntawm cov ntsiab lus carbon. Feem ntau cov hlau tsis muaj cov ntsiab lus carbon tsawg, thiab qee cov hlau tseem muaj cov ntsiab lus carbon hauv qab 0.03% (xws li 00Cr12 Lub ntsiab alloying nyob rau hauv stainless hlau yog chromium, uas yog lub hauv paus ntsiab lus uas ua rau cov hlau tsis muaj corrosion kuj. oxide zaj duab xis nyob rau saum npoo ntawm cov hlau, uas tuaj yeem tiv thaiv corrosion ntxiv ntawm cov hlau substrate. Ntxiv nrog rau chromium, feem ntau siv alloying ntsiab muaj xws li npib tsib xee, molybdenum, titanium, niobium, tooj liab, nitrogen, thiab lwm yam. siv rau cov qauv thiab cov khoom ntawm stainless hlau
