Lub twj tso kua mis dej muaj ob yam tseem ceeb: thawj zaug, nws tsis xeb, thiab qhov thib ob, nws tuaj yeem tiv taus qhov kub thiab txias. Tab sis thaum lub npoo ntawm stainless hlau dej twj tso kua mis rusts, cov neeg yuav xav tias stainless hlau tsis xeb. Ua li cas nws xeb? Puas muaj teeb meem zoo nrog kev yuav khoom. Qhov tseeb, qhov kev xav no tsis raug. Raws li lub npe qhia, cov khoom tseem ceeb ntawm stainless hlau dej twj yog stainless hlau, uas tsis muaj xeb thiab corrosion kuj. Tab sis nws txoj kev tiv thaiv - muaj peev xwm corrosion nyob ntawm kev siv thiab ib puag ncig. Qhov ntawd yog hais tias, tsis yog txhua hom stainless hlau tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.
Ntawm no, tus editor tau qhia qee qhov kev paub txog stainless hlau dej twj tso kua mis rau txhua tus. Stainless hlau muaj peev xwm tiv thaiv kev nkag mus tsis tu ncua ntawm oxygen atoms los ntawm chromium nplua nuj oxide zaj duab xis ntawm nws qhov chaw, uas ntxiv oxidizes thiab tiv thaiv xeb corrosion. Txawm li cas los xij, yog tias cov yeeb yaj kiab no tsis tu ncua, cov pa oxygen atoms hauv huab cua lossis cov kua txuas ntxiv nkag mus, lossis cov hlau atoms hauv cov hlau tau raug tshuaj xyuas tas li los tsim cov hlau oxide xoob, cov hlau saum npoo yuav raug corroded tsis tu ncua.
Nyob rau tib lub sijhawm, vim qhov tshwj xeeb siv ib puag ncig ntawm stainless hlau dej twj tso kua mis, cov khoom yuav tsum tau ceev faj heev thaum yuav khoom. Peb xav paub qhov tseeb ntawm cov ntaub ntawv thiab seb lawv puas yuav raug muag zoo kom tsis txhob raug dag. Ntawm no, tus editor piav qhia txog ntau txoj hauv kev siv rau kev siv nkaus xwb.
1. Cov cim xim yog pickling stainless hlau, nrog ib tug silver dawb nto xim uas yog huv heev: chrome nickel stainless hlau nyiaj dawb yog jade xim. Chromium stainless hlau muaj me ntsis greyish dawb xim thiab tsis muaj zog luster; Cov xim ntawm chromium nitrogen stainless hlau zoo ib yam li cov chromium nickel stainless hlau. Cov xim saum npoo ntawm cov hlau tsis huv: Chromium nickel steel yog xim av, chromium hlau yog xim av, thiab chromium nitrogen yog xim dub (cov xim peb no hais txog cov xim uas hnyav dua oxidation). Txias dov chromium npib tsib xee stainless hlau yam tsis muaj degradation muaj ib tug silver dawb nto reflection.
2. Stainless hlau twj tso kua mis siv cov hlau nplaum kom paub qhov txawv ntawm ob hom stainless hlau. Vim tias chromium stainless hlau tuaj yeem nyiam los ntawm cov hlau nplaum hauv txhua lub xeev. Chromium nickel stainless hlau feem ntau tsis muaj hlau nplaum hauv lub xeev annealed, tab sis nws kuj muaj hlau nplaum tom qab ua haujlwm txias. Tab sis siab manganese hlau tsis muaj hlau nplaum. Cov khoom sib nqus ntawm chromium, nickel, nitrogen, thiab stainless hlau yog qhov nyuaj dua. Qee tus tsis muaj hlau nplaum, qee qhov muaj hlau nplaum, qee qhov tsis muaj hlau nplaum nyob rau hauv ntu ntev, thiab qee qhov muaj hlau nplaum hauv ntu ntu. Yog li, cov hlau nplaum tuaj yeem paub qhov txawv ntawm chromium stainless hlau thiab chromium nickel stainless hlau, tab sis tsis tuaj yeem paub qhov txawv ntawm cov khoom tshwj xeeb ntawm cov qib steel, thiab lawv tsis tuaj yeem paub qhov txawv ntawm cov qib steel.
3. Stainless hlau dej twj siv tooj liab sulfate los txheeb xyuas thiab tshem tawm cov oxide txheej ntawm cov hlau. Ntxiv ib tee dej thiab so nrog tooj liab sulfate tsis hloov xim. Feem ntau, nws yog stainless hlau. Tig ntshav, tsis yog- hlau nplaum yog siab manganese hlau, thiab hlau nplaum feem ntau yog cov hlau zoo tib yam lossis qis- alloy steel lossis siab dua. Ob qho tib si yog kev txheeb xyuas qhov tseeb, thiab cov txiaj ntsig kev txheeb xyuas yuav tsis raug thiab yuav tsum tau ntxiv. Ntxiv mus, nws tsuas tuaj yeem txheeb xyuas qib steel ntawm stainless hlau thiab tsis tuaj yeem txheeb xyuas cov khoom siv tshwj xeeb.
