Qhov kev tiv thaiv corrosion ntawm stainless hlau cua sov raj tsis yog qhov tseeb, tab sis tus txheeb ze thiab cov xwm txheej. Tam sim no, tsis muaj qib steel uas tsis corrode nyob rau hauv ib puag ncig hauv tsev lossis txawv teb chaws. Stainless hlau hluav taws xob cua sov raj kuj tsis siv rau hauv ib puag ncig, yog li xeb tuaj yeem tshwm sim. Lub neej ntev ntawm cov kab xeb tsis tsuas yog cuam tshuam rau cov tsos, tab sis kuj txo cov kev pab cuam lub neej vim qhov corrosion ntawm cov yeeb nkab stainless hlau. Cov kab xeb ntawm qhov chaw ntawm cov yeeb nkab stainless hlau yuav tsum tau kho raws sijhawm. Niaj hnub no peb yuav tham txog yuav ua li cas daws cov kab xeb ntawm cov cua sov raj?
Mechanical method:
Yog li ntawd, mechanically cleaned nto yuav tsum tau ntxuav kom zoo nyob rau hauv qhuav tej yam kev mob. Kev siv cov txheej txheem siv tshuab tsuas tuaj yeem ntxuav qhov chaw, thiab tsis tuaj yeem hloov qhov corrosion kuj ntawm cov khoom nws tus kheej. Yog li ntawd, nws raug nquahu kom rov polishing nrog cov khoom siv polishing tom qab kho tshuab thiab sealing nrog polishing wax.
Sandblasting, siv iav los yog ceramic particle tua blasting, rhuav tshem, txhuam thiab polishing. Nws tuaj yeem siv cov txheej txheem siv tshuab los so cov pa phem los ntawm cov khoom siv yav dhau los tshem tawm, polishing cov ntaub ntawv lossis cov ntaub ntawv pov tseg. Txhua yam kev ua qias tuaj, tshwj xeeb tshaj yog cov hlau txawv teb chaws, tuaj yeem dhau los ua qhov chaw ntawm corrosion, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej.
chemical method:
Nws yog qhov zoo tshaj plaws los siv txhuam txhuam los txhuam nws ob peb zaug thaum lub sijhawm kho. Tom qab cov nplai oxide saum npoo raug tshem tawm tag, yaug nws nrog dej huv (cov dej txiv qaub lossis dej alkaline zoo dua) kom tsis txhob rov qab xeb. Tom qab pickling, thiaj li yuav tshem tawm tag nrho cov kab mob thiab acid residues, nws yog ib qho tseem ceeb heev kom yaug nrog dej huv. Tom qab tag nrho cov kev kho mob, rov polishing nrog polishing khoom thiab sealing nrog polishing ciab. Rau cov neeg uas muaj xeb me ntsis, koj tuaj yeem siv cov roj av hauv 1: 1 thiab cov roj cav sib tov los so cov pob xeb nrog cov ntaub huv. Siv tshuaj tsuag los yog muab tshuaj txhuam los pab kom rov ua dua ntawm cov xeb xeb los tsim cov chromium oxide zaj duab xis los kho cov corrosion kuj. Siv cov tshuaj pleev xim rau saum npoo kom kho, lub thickness ntawm txheej zaj duab xis yog 0.5-2mm, lub sij hawm tshuaj tiv thaiv dav dav yog 3-10 feeb lossis ntau dua, thaum nws siv hauv qab no 0 degree lossis qhov twg cov nplai oxide tuab, lub sijhawm yuav tsum tau txuas ntxiv kom tsim nyog.
