Yuav ua li cas tuav lub tshuab hluav taws xob stainless hlau

Kev tiv thaiv corrosion ntawm stainless hlau hluav taws xob cua sov tsis yog qhov tseeb, tab sis muaj cov xwm txheej. Tam sim no, tsis muaj stainless hlau nyob rau hauv ib puag ncig ob qho tib si domestic thiab thoob ntiaj teb. Stainless hlau hluav taws xob cua sov kuj yog ib qho nyuaj rau siv nyob rau hauv txhua qhov chaw, yog li lawv muaj rusting. Lub neej ntev ntawm cov xeb tsis tsuas yog cuam tshuam rau kev zoo nkauj, tab sis kuj txo cov kev pab cuam lub neej vim corrosion ntawm qhov chaw ntawm stainless hlau yeeb nkab fittings. Cov kab xeb ntawm qhov chaw ntawm cov kav hlau stainless yuav tsum tau kho raws sijhawm. Tam sim no cia peb tham txog yuav ua li cas daws cov kab xeb ntawm cov kav hlau tsis muaj hluav taws xob hluav taws xob.
Nyob rau hauv cov cheeb tsam corroded, tshuaj tsuag los yog pickling muab tshuaj txhuam yuav siv tau los pab passivation, tsim ib tug chromium oxide zaj duab xis thiab restore nws corrosion kuj. Siv cov kua qaub pickling muab tshuaj txhuam rau ntawm qhov chaw los kho, nrog rau zaj duab xis tuab ntawm {{{0}} 5-2 hli thiab lub sijhawm tshuaj tiv thaiv ntawm 3-10 feeb. Tom qab ua tiav hauv thaj chaw qis dua 0 degree lossis nrog cov nplai tuab, lub sijhawm yuav tsum tau txuas ntxiv kom tsim nyog. Txhuam ob peb zaug ua ntej siv, tshem tawm cov nplais saum npoo, thiab tom qab ntawd yaug nrog dej huv (cov dej txiv qaub lossis dej alkaline) kom tsis txhob xeb.
Tom qab pickling, nws yog ib qho tseem ceeb heev uas yuav tsum yaug nrog dej kom tsim nyog thiaj li yuav tshem tawm cov pa phem thiab acids. Tom qab tag nrho cov txheej txheem, siv cov cuab yeej polishing los rov polish thiab foob nrog polishing. Rau cov cheeb tsam uas muaj xeb me ntsis, 1: 1 roj av kuj tuaj yeem siv los so cov roj sib tov nrog ib daim ntaub huv. Sandblasting, ntxuav nrog iav los yog ceramic hais, polishing, txhuam, thiab polishing.
Kev kis kab mob tshwm sim los ntawm cov khoom siv yav dhau los tshem tawm, cov khoom siv polished, thiab cov ntaub ntawv pov tseg tuaj yeem raug wiped mechanically. Txhua yam kuab paug, tshwj xeeb tshaj yog cov hlau txawv teb chaws, tuaj yeem yog qhov chaw ntawm corrosion, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej. Yog li ntawd, cov tshuab ntxhua khaub ncaws yuav tsum tau ntxuav tsis tu ncua nyob rau hauv ib qho chaw qhuav kom ntau li ntau tau. Cov txheej txheem siv tshuab tsuas tuaj yeem ntxuav qhov chaw thiab tsis tuaj yeem hloov kho corrosion ntawm cov khoom nws tus kheej. Yog li nws raug pom zoo kom siv cov cuab yeej polishing tom qab kev tu txhua yam, thiab tom qab ntawd muab khi nrog polishing ciab.
