Yuav ua li cas kom tsis txhob muaj qhov tshwm sim ntawm corrosion ntawm cov ntsia hlau ntsaws?
Vim tias cov ntsia hlau ntsaws muaj cov khoom siv hluav taws xob thiab kev tiv thaiv corrosion, nws yog dav siv nyob rau hauv ntau yam tshuab engineering. Txawm li cas los xij, nyob rau hauv tus txheej txheem ntawm kev siv, kuj tseem yuav muaj qee qhov teeb meem, uas yog, cov ntsia hlau ntsaws yuav raug corroded nyob rau hauv lub sij hawm ntev yaig ntawm ib puag ncig sab nraud, yog li peb yuav ua li cas kom tsis txhob muaj qhov xwm txheej no?
Ua ntej tshaj plaws, peb yuav tsum xaiv cov ntsaws ruaj ruaj uas tsim nyog thiab zoo, thiab tsis txhob siv cov ntsia hlau tsis zoo nrog qhov khoob lossis cov khoom tso rau ntawm qhov chaw. Tom qab ntawd peb yuav tsum cais cov ntsia hlau ntsaws thiab cov tshuaj aqueous uas muaj chloride ions. Yog tias muaj qhov sib txawv ntawm qhov sib txuas, peb tuaj yeem ntxiv lub gasket lossis vuam qhov sib txawv los thaiv qhov sib txawv kom cov kua dej tsis tuaj yeem nkag mus.
Yog tias muaj cov kev cai tshwj xeeb, nws yog qhov zoo tshaj plaws los siv cov khoom siv stainless hlau uas muaj cov chromium siab thiab molybdenum siab hauv cov khoom muaj pes tsawg leeg. Cov ntaub ntawv stainless hlau no muaj kev tiv thaiv corrosion ntau dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qis qis, qhov chaw tank kheej kheej thiab thaj chaw uas muaj kev ntxhov siab hnyav, thiab cov nyhuv tseem ceeb dua. .
Qhov thib ob, peb yuav tsum passivate lub hau ntsaws ntsaws. Kev kho mob Passivation ntawm cov ntsia hlau ntsaws yog hais txog kev siv tshuaj siv los siv cov txheej txheem tiv thaiv ntawm cov hlau. Lub hom phiaj yog cais cov hlau los ntawm qhov chaw corrosive, yog li inhibiting cov txheej txheem corrosion. Los yog txo qhov kev sib cuag ntawm nruab nrab corrosive thiab hlau nto kom tsis txhob los yog txo corrosion.
