Stainless hlau yog ntau tshaj li ib tug corrosion resistant hlau.Stainless hlau feem ntau raug xaiv los ua ntau yam khoom siv rau ntau daim ntawv thov vim nws lub zog, kev tiv thaiv corrosion thiab muaj peev xwm hloov mus rau cov xwm txheej tshwj xeeb.
304 304L 316 316L Stainless hlau phaj lwm tus neeg nyob hauv Suav teb
Stainless hlau 304 yog cov qib stainless hlau siv dav tshaj plaws.Nws yog ib qho chromium-nickel austenitic stainless hlau uas muaj cov ntsiab lus ntawm cov pa roj carbon tsawg thiab me ntsis siab dua chromium thiab npib tsib xee dua li AISI hom 301 thiab 302. Qib 304 yog ductile heev thaum nyob rau hauv ib qho kev mob annealed.Nws muaj qhov kub siab zoo thiab zoo toughness ntawm qhov kub thiab txias.Nws yog qhov zoo rau kev vuam thiab qhov twg cov khoom tiav yuav tsum tiv taus cov ntaub ntawv hnyav dua ntawm corrosion.

Qhov no siv tsis tau tsuas yog rau cov tshuaj sib txawv uas tsim los ntawm cov hlau tsis muaj steel, tab sis kuj rau cov txheej txheem sib txawv thiab kev kho deg uas tau thov nyob ntawm qhov kawg npaj siv cov khoom.
Qib 2B yog ib qho ntawm cov kev kho mob feem ntau siv hauv kev lag luam stainless hlau.Nws yog semi-reflective, du thiab uniform, tab sis tsis yog daim iav.Kev npaj nto yog cov kauj ruam kawg hauv cov txheej txheem: cov ntawv hlau yog thawj zaug los ntawm nias ntawm yob ntawm qhov hluav taws xob ntawm lub qhov cub.Tom qab ntawd nws yog softened los ntawm annealing thiab rov qab los ntawm yob.
Txhawm rau tshem tawm cov kab mob, qhov saum npoo yog acid-etched thiab dhau ntawm polishing rollers ob peb zaug kom ua tiav qhov xav tau tuab.Nws yog qhov kawg dhau los ua kom tiav 2B.
2B yog cov txheej txheem tiav ntawm cov qib stainless hlau ntau, suav nrog 201, 304, 304 L, thiab 316 L. Qhov nrov ntawm 2B polishing, ntxiv rau kev lag luam thiab kev tiv thaiv corrosion ntau dua, nyob hauv qhov yooj yim ntawm polishing nrog lub log ntaub thiab compound.
Feem ntau, 2B tiav steel yog siv rau hauv kev ua zaub mov, khoom noj khoom haus, ntim khoom, ntim cia, thiab cov khoom siv tshuaj thiab ua tau raws li USDA cov qauv rau cov kev lag luam no.
Txoj hauv kev no tsis tuaj yeem siv tau thaum cov khoom kawg yog kev txhaj tshuaj lossis otic kua.Qhov no yog vim qhov khoob lossis hnab ris tuaj yeem tsim rau ntawm cov hlau.Cov voids no tuaj yeem ntes cov kab mob hauv qab ntawm polished nto los yog hauv cov hlau.Thaum kawg, cov khoom txawv teb chaws no tuaj yeem khiav tawm thiab kis cov khoom.Deg electropolishing yog qhov zoo tshaj plaws thiab pom zoo txoj hauv kev los txhim kho deg smoothness rau cov ntawv thov.
Electropolishing ua haujlwm los ntawm kev siv tshuaj lom neeg thiab hluav taws xob kom du tawm cov cheeb tsam ntawm cov hlau stainless.Txawm tias muaj lub Hoobkas siv Smooth 2B Txheej, qhov tseeb stainless hlau nto yuav tsis zoo li du thaum magnified.
Nruab Nrab Roughness (Ra) yog siv los xa mus rau qhov smoothness ntawm cov hlau nto thiab yog qhov sib piv ntawm qhov nruab nrab qhov sib txawv ntawm cov ntsiab lus qis thiab siab ntawm lub sijhawm.
Feem ntau, lub Hoobkas tshiab stainless hlau nrog 2B tiav muaj tus nqi Ra nyob rau hauv thaj tsam ntawm 0.3 micron (0.0003 hli) txog 1 micron (0.001 hli) nyob ntawm nws qhov tuab (thickness).Nto Ra tuaj yeem txo mus rau 4-32 micro ntiv tes los ntawm electropolishing kom zoo, nyob ntawm cov yam ntxwv ntawm cov hlau.
Ib chav kawm 2B tiav yog ua tiav los ntawm compressing cov khoom nrog ob lub rollers.Qee tus neeg ua haujlwm xav tau kev kho kom zoo tom qab kho dua tshiab lossis kho lub nkoj lossis lwm yam khoom siv.
Txawm hais tias qhov saum npoo tiav tau los ntawm kev siv tshuab lossis electropolishing tsis yooj yim rov tsim dua, nws tuaj yeem nyob ze, tshwj xeeb tshaj yog hais txog Ra qhov tseem ceeb.Raws li qhov tshwm sim ntawm kev kho electropolishing kom zoo, txawm tias kev ua tau zoo dua ntawm kev ua cov khoom siv tuaj yeem ua tiav dua li qhov qub tsis tiav 2B nto kho.
Yog li, kev kwv yees 2B tuaj yeem suav tias yog qhov pib zoo.2B txheej txheej muaj cov txiaj ntsig zoo thiab muaj txiaj ntsig zoo.Nws tuaj yeem txhim kho ntxiv nrog electropolishing rau kev ua tiav zoo dua, cov qauv siab dua thiab ntau yam txiaj ntsig ntev.
