Stainless hlau fwj ua lub luag haujlwm tseem ceeb hauv lub neej niaj hnub no thiab nyiam rau lawv cov kev ua tau zoo thiab ua haujlwm ntev. Ntawm lawv, 304- qib stainless hlau tau nyiam ntau xim rau nws zoo heev corrosion kuj thiab tsis tshua muaj hlau nplaum. Txawm li cas los xij, tseem muaj cov khoom sib txawv ntawm cov khoom lag luam. Hauv qab no, GINT yuav qhia ob peb txoj hauv kev yooj yim thiab siv tau los txheeb xyuas 304- qib stainless hlau, thiab peb kuj tuaj yeem nrhiav tau qee qhov qhia los ntawm kev soj ntsuam txhua hnub.
Yuav kuaj li cas 304-qib stainless hlau?
1. Stainless hlau kuaj kua
Siv stainless hlau kuaj kua yog ib txoj kev yooj yim. Tsuas yog tso cov kua ntsuas rau ntawm qhov chaw ntawm cov hlau tsis huv kom kuaj xyuas. Tom qab li ntawm 2-3 feeb, cov xim yuav hloov. Cov xim sib txawv sib txawv rau ntau hom stainless hlau. Tiag 304- qib stainless hlau yuav tsis hloov xim li ntawm 3 feeb, lossis xim hauv qab yuav tsaus me ntsis. Feem ntau, stainless hlau kuaj kua tuaj nrog cov duab sib piv, uas tso cai rau koj los txiav txim siab cov khoom raws li cov txiaj ntsig.
1. Ua ntej kuaj, so cov plua plav, av, roj thiab dej ntawm cov khoom siv los kuaj.
2. Cov khoom no yog me ntsis corrosive. Yog tias nws raug mob ntawm koj daim tawv nqaij, thov yaug nrog dej huv.
3. Cov txiaj ntsig ntawm qhov ntsuas saum toj no yog kwv yees qhov muaj nqis. Tib qib ntawm stainless hlau yuav muaj qhov sib txawv me ntsis vim yog kev hloov pauv hauv lub koom haum, lub xeev nto thiab lwm yam uas cuam tshuam rau kev ua haujlwm ntawm xeb.
4. Tsis tas li ntawd, thaum lub ambient kub siab, lub peev xwm corrosion ntawm cov reagent kuj yuav nce, thiab cov tshuaj tiv thaiv ceev kuj yuav nce, uas ua rau muaj qhov sib txawv me ntsis.
2. Magnetic Identification
Kev kuaj hlau nplaum yog ib txoj hauv kev yooj yim kom paub qhov txawv ntawm cov hlau tsis muaj hlau los ntawm lwm cov ntaub ntawv. Txawm hais tias stainless hlau feem ntau tsis sib nqus, qee qib, suav nrog 304, tuaj yeem pom cov hlau nplaum tsis muaj zog. Muab cov hlau nplaum nyob ze ntawm qhov chaw ntawm cov hlau tsis muaj steel. Yog tias nws muaj zog txaus nyiam los yog lo rau saum npoo, nws feem ntau yuav tsis yog 304 stainless hlau.
3. Copper Sulfate Test
Tshem tawm cov oxide txheej los ntawm qhov chaw ntawm cov hlau, ntxiv ib tee dej, thiab so nrog tooj liab sulfate. Yog tias tsis muaj kev hloov xim, nws feem ntau yog stainless hlau. Yog tias nws hloov ntshav-liab, nws yuav yog cov hlau tsis sib nqus high-manganese, thiab yog tias nws pom cov hlau nplaum, nws yuav yog cov hlau zoo tib yam lossis cov hlau tsis tshua muaj hlau.
4. Kev Ntsuas Ntsuas
Lub txim hluav taws xob yog ua los ntawm kev sib tsoo cov hlau tsis huv ntawm lub log sib tsoo thiab soj ntsuam cov sparks. Yog hais tias lub sparks yog streamlined, nrog ntau ntom paj zoo li cov qauv, nws yuav qhia tau hais tias ib tug siab manganese cov ntsiab lus, xws li high-manganese steel los yog manganese-ammonia steel.
5. Tshuaj ntsuam xyuas
Kev tshuaj xyuas tshuaj yog ib txoj hauv kev zoo dua los txiav txim siab qib ntawm stainless hlau. Nws suav nrog kev coj tus qauv me me thiab kuaj nws tshuaj. Qhov no tuaj yeem ua tiav los ntawm cov txheej txheem spectroscopic xws li X-ray fluorescence (XRF) lossis cov tshuaj ntub dej hauv chav kuaj. Cov kev ntsuam xyuas no tuaj yeem txheeb xyuas cov ntsiab lus ntawm cov hlau tsis muaj steel thiab paub meej tias nws puas ua tau raws li qhov xav tau ntawm qib 304.
Xaus
304 stainless hlau muaj ntau dua 18% chromium thiab ntau dua 8% npib tsib xee, uas yog ob qho tseem ceeb uas txiav txim siab tus nqi ntawm 304 cov ntaub ntawv. Cov hlau muaj zoo toughness, plasticity thiab corrosion kuj thiab kuj yog dav siv. Txawm li cas los xij, qhov zoo ntawm stainless hlau nyob rau hauv kev ua lag luam tsis sib xws, muaj cov khoom tsis zoo thiab cov khoom cuav, ntau tus neeg yuav khoom tsis paub yuav xaiv li cas.
Los ntawm kev siv cov txheej txheem saum toj no, peb tuaj yeem txheeb xyuas cov khoom ntawm cov hlau tsis muaj steel, xyuas kom meej tias peb yuav txhim khu kev qha 304 qib stainless hlau fwj rau kev siv txhua hnub, thiab muab kev yooj yim thiab kev thaj yeeb rau peb.
