Nyob ntawm cov txheej txheem ua haujlwm, muaj rau cov qauv acid Ntawm cov no, cov qauv raus dej, tshuaj txhuam, thiab cov txheej txheem txau tau ntau dua rau cov kua qaub pickling thiab passivation ntawm stainless hlau tso tsheb hlau luam thiab khoom siv.
Txoj kev Immersion:Hom no yog feem ntau haum rauStainless hlau xa, lauj tshib, seem me me, thiab muab cov nyhuv zoo tshaj plaws. Raws li cov khoom kho tuaj yeem tso siab tag nrho hauv cov kua qaub pickling thiab passivation daws, cov tshuaj tiv thaiv nto yog ua tiav, thiab cov zaj duab xis tseem ntawm thiab hnav khaub ncaws. Hom no yog haum rau cov haujlwm txuas ntxiv mus tab sis yuav tsum tau txuas ntxiv ntawm cov kev daws teeb meem tshiab raws li cov kev daws teeb meem reacting tsawg. Nws cov drawbback yog tias nws txwv los ntawm cov duab thiab peev xwm ntawm cov khoom siv acid thiab tsis haum rau cov khoom siv acid los yog cov raj xa khoom nrog ntev dhau los lossis dav duab. Yog tias tsis yog siv rau lub sijhawm ntev, qhov ua tau zoo yuav txo qis los daws cov xaib ntawm cov khoom siab, cov khoom siv acid tank, thiab cov khoom siv kua qaub.
Muab tshuaj txhuam: Cov kua qaub pickling muab tshuaj txhuam rau stainless hlau yog dav siv domestically thiab muaj nyob rau hauv cov khoom lag luam. Nws cov khoom siv tseem ceeb muaj xws li nitric acid, hydrofluoric acid, corrosion inhibitors, thiab thickening cov neeg sawv cev, nyob rau hauv cov proportions. Nws yog tus tswv ua ntawv thov thiab haum rau kev siv rau ntawm chaw. Nws yog siv rau cov pickling thiab passivation ntawm stainless hlau tank vuam, fab tom qab vuam, ntaiv nraub qaum, thiab cov chaw loj hauv cov thawv ua kua.
Qhov zoo ntawm cov txheej txheem muab tshuaj txhuam yog tias nws tsis tas yuav muaj cov khoom siv tshwj xeeb lossis cov khoom siv cua sov, acids ua tiav nyob rau hauv ib kauj ruam, thiab nws yog ywj pheej. Qhov passivation passe muaj lub txee ntev ntev, thiab txhua daim ntawv thov siv rov ua haujlwm tshiab rau ib zaug siv. Cov tshuaj tiv thaiv nres tom qab txheej saum npoo ntawm passivation, ua rau nws tsis tshua muaj rau over-corrosion. Nws tsis yog txwv los ntawm kev muab yaug lub sijhawm tom qab, thiab ua haujlwm hla dhau thaj chaw uas tsis muaj zog xws li Welds tuaj yeem siv zog. Qhov tsis zoo yog tias ib puag ncig ua haujlwm rau tus neeg teb chaws yuav yog kev siv tsis zoo, thiab cov nyhuv muaj zog, xav tau kev sib xyaw nrog lwm txoj hauv kev.
Txau txoj kev:Haum rau cov chaw ruaj, kaw ib puag ncig, kaw ib puag ncig, lossis khoom siv nrog cov acid pickling thiab passive, xws li cov tshuaj txau rau ntawm ib daim ntawv hlau ntau lawm. Nws cov txiaj ntsig yog kev ua haujlwm tsis tu ncua, kev ua haujlwm yooj yim, kev hloov kho me me ntawm cov neeg ua haujlwm, thiab cov txheej txheem hloov tuaj yeem txau cov raj xa hluav taws xob ntxiv nrog acid. Nws muaj tus nqi ntawm qhov tseem ceeb ntawm kev daws teeb meem.
