Sterile Processing Departments (SPDs) inevitably yuav tsum tau nrog stainless hlau corrosion, kuj hu ua xeb. Corrosion nyob rau hauvchav sterilizersyog tshwm sim los ntawm cov tshuaj tiv thaiv ntawm ya raws thiab stainless hlau. Thaum corrosion feem ntau yog ib qho teeb meem tsis to taub rau ntau tus, nws yog ib qho tseem ceeb uas yuav tsum tau tshem tawm kom tsis txhob raug nqi kho.
Yog tias tsis muaj chaw nyob, chav sterilizer corrosion tuaj yeem:
Ua rau muaj kab mob, ua rau lub cev tsis ua haujlwm
Ua kom cov khoom siv downtime thiab kho tsis tau npaj
Yuav tsum tau them nqi hloov ua ntej tshaj qhov kev npaj
Dab tsi yog stainless hlau corrosion (xeb)?
koj puas paub? Qhov tseeb yog, stainless hlau tseem tuaj yeem stained. Nws yuav muaj tseeb rau nws lub npe yog tias nws hu ua anti-fouling steel. Thaum cov txheej txheej passivation ntawm nws qhov chaw puas, eroded lossis cuam tshuam, cov hlau hauv qab yuav pib oxidize ua rau staining.
Stainless hlau corrosion, tseem hu ua "xeb," piav qhia ntau yam xim ntawm qhov chaw. Cov xim nyob ntawm tus nqi ntawm cov pa oxygen ntawm qhov chaw raug. Corrosion nyob rau hauv chav kav dej feem ntau yog dub, thaum corrosion nyob rau hauv autoclave chambers feem ntau yog xim liab-xim av ntawm phab ntsa. Txawm hais tias nws yog dej ntshiab, dej ultrapure, chav dej los yog cov kais dej yooj yim, xeb tuaj yeem tshwm sim vim muaj dej los yog noo noo uas accumulates ntawm qhov chaw.
Txij li thaum corrosion yog tshwm sim los ntawm cov tshuaj tiv thaiv ntawm ya raws thiab stainless hlau, qhov no yog ib tug unavoidable nyhuv. Txhim khu kev tiv thaiv corrosion ntawm stainless hlau cov cuab yeej thiab pib tshem tawm xeb yuav tsum yog ib feem tseem ceeb ntawm txhua qhov kev ua haujlwm tsis muaj menyuam txoj kev tiv thaiv kev saib xyuas.
Dab tsi yog txoj hauv kev zoo tshaj los txo cov xeb ntawm cov hlau tsis muaj steel?
Txo kev sib cuag nrog dej thiab noo noo. Thaum qhov no yuav zoo li nyuaj, nco ntsoov tias cov sterilizers siv chav qhuav hauv lawv lub voj voog. "Npaj ntub dej" yuav qhia tau tias muaj teeb meem nrog koj cov cuab yeej, uas yog tias tsis daws, yuav ua rau tsis ua haujlwm.
Tsis txhob siv cov tshuaj uas yuav cuam tshuam rau cov zaj duab xis passive ntawm stainless hlau. Cov tshuaj abrasive tuaj yeem khawb qhov chaw, thaum cov khoom siv ntxuav hnyav xws li tshuaj dawb tuaj yeem ua rau cov txheej txheem tiv thaiv.
Siv cov txheej txheem tu niaj hnub rau kev tshem tawm xeb thiab passivation ntawm cov khoom tsim hluav taws xob. Kev tshem tawm tsis tu ncua thiab kev tiv thaiv corrosion ua kom cov khoom siv poob qis tsawg.
Yuav ua li cas daws Stainless Hlau Corrosion
Txij li thaum corrosion yog inevitable nyob rau lub sij hawm, thaum nws tshwm sim, nws yuav tsum tau hais sai sai los tiv thaiv corrosion ntxiv thiab ua kom cov cuab yeej khiav hauj lwm zoo. Cov txheej txheem rau kev tshem tawm xeb thiab passivation ntawm cov khoom siv stainless hlau suav nrog:
Txiav txim siab qhov ua rau corrosion los ntawm kev tau txais kev ntsuam xyuas raws li kev soj ntsuam. Raws li qhov ua rau, kev ntsuas dej zoo tuaj yeem muab kev nkag siab txog kev tiv thaiv corrosion yav tom ntej.
Ntxuav nrog cov tshuaj alkaline kom tshem tawm cov organic residues. Kev kho cov kua qaub tuaj yeem siv los tshem tawm cov hlau oxide
Ntxiv txheej tiv thaiv kom tsis txhob muaj corrosion ntxiv
Tshem tawm xeb thiab tarnish los ntawm stainless hlau
Txij li cov xeb yog hlau oxide, cov tshuaj uas ua rau cov hlau oxide tshem tawm cov xeb. Cov txheej txheem no, hu ua deodorization, yuav tsum tau kho kom haum rau hom tshwj xeeb ntawm corrosion thiab tej zaum yuav muaj cov tshuaj uas yuav tsum tau siv cov cuab yeej tiv thaiv tus kheej, yog li nws raug pom zoo kom siv cov txheej txheem ua pov thawj rau kev ua tiav deodorization.
