Dab tsi yog yam uas tuaj yeem ua rau 304 stainless hlau xeb?
304 stainless hlau paub txog nws zoo heev corrosion kuj, tab sis nyob rau hauv tej yam xwm txheej, nws tseem tuaj yeem xeb.
Ib qho ntawm cov ntsiab lus tseem ceeb uas tuaj yeem ua rau xeb yog raug rau qhov chaw hnyav, xws li cov av noo siab, dej ntsev, lossis cov kua qaub.
Lwm qhov tseem ceeb yog kev sib kis ntawm qhov chaw, xws li raug hlau lossis carbon hlau, uas tuaj yeem ua rau galvanic corrosion.
Tsis tas li ntawd, kev cia khoom tsis raug lossis kev tuav pov hwm kuj tuaj yeem ua rau xeb, vim tias khawb lossis dents ntawm qhov chaw tuaj yeem tsim cov chaw kom ya raws thiab oxygen nkag mus. Nws yog ib qho tseem ceeb los tswj thiab ntxuav cov hlau tsis tu ncua kom tsis txhob xeb.
Siv cov txheej tiv thaiv, xws li pleev xim lossis electroplating, tuaj yeem pab txhim kho nws cov kev tiv thaiv corrosion.
Los ntawm kev nkag siab txog yam uas tuaj yeem ua rau xeb, peb tuaj yeem ua cov kauj ruam tiv thaiv thiab txuas ntxiv lub neej ntawm 304 stainless hlau hauv ntau daim ntawv thov.
304 stainless hlau yog cov khoom siv corrosion-resistant, tab sis nws tsis yog tiv thaiv xeb tag. Muaj ntau txoj hauv kev los tiv thaiv nws los ntawm xeb, suav nrog:
Kev Tiv Thaiv Passive: Cov txheej txheem feem ntau yog kev tiv thaiv passive, uas cuam tshuam nrog tsim cov txheej nyias nyias ntawm chromium oxide rau ntawm cov hlau. Cov txheej no tiv thaiv cov hlau hauv qab ntawm ib puag ncig thiab tiv thaiv xeb. Txoj kev no siv tau ntev npaum li qhov chaw tsis raug puas los yog muaj kab mob.
Txheej: Lwm txoj hauv kev los tiv thaiv 304 stainless hlau yog los ntawm kev siv cov txheej txheem, xws li xim lossis hmoov txheej. Cov coatings no ua ib qho kev thaiv ntawm cov hlau thiab ib puag ncig, tiv thaiv cov dej noo thiab oxygen los ntawm qhov chaw.
Kev Tiv Thaiv Cathodic: Txoj kev no suav nrog kev txuas cov hlau mus rau cov hlau ntau dua, xws li zinc lossis magnesium. Cov hlau no corrode sai dua li cov hlau tsis muaj steel, txi lawv tus kheej los tiv thaiv cov hlau los ntawm xeb.
Kev Tu thiab tu kom zoo: Kev tu thiab tu tsis tu ncua tuaj yeem pab tiv thaiv xeb los ntawm kev tshem tawm cov kab mob thiab ua kom lub ntsej muag qhuav.
Los ntawm kev ua raws li cov txheej txheem no, nws tuaj yeem tiv thaiv xeb thiab ua kom lub neej ntev ntawm 304 stainless hlau hauv ntau daim ntawv thov, suav nrog kev tsim kho, kev ua zaub mov, thiab khoom siv kho mob.
Yuav ua li cas 304 stainless hlau tiv thaiv los ntawm xeb?
Puas yog 304 stainless hlau ntau dua los yog tsawg dua rusting piv rau lwm hom stainless hlau?
Thaum nws los txog rau stainless hlau, lub npe ib leeg tuaj yeem dag. Tsis yog tag nrho cov hlau tsis muaj steel yog tsim sib npaug, thiab txhua tus muaj nws tus kheej cov khoom uas cuam tshuam rau nws txoj kev tiv thaiv xeb. Thaum 304 stainless hlau paub txog nws zoo heev corrosion kuj, nws tsis tiv thaiv xeb. Qhov tseeb, nyob ntawm qhov chaw tshwj xeeb, nws yuav muaj ntau dua los yog tsawg dua rau xeb piv rau lwm hom stainless hlau.
Piv txwv li, 316 stainless hlau muaj molybdenum, uas txhim kho nws cov corrosion kuj nyob rau hauv ntau aggression ib puag ncig xws li marine ib puag ncig. Ntawm qhov tod tes, 430 stainless hlau muaj ntau dua ntawm chromium tab sis tsis muaj npib tsib xee, ua rau nws pheej yig dua tab sis kuj tsis tshua muaj kev tiv thaiv corrosion dua li 304 stainless hlau.
Nyob rau hauv luv luv, rusting susceptibility ntawm stainless hlau nyob ntawm nws cov tshuaj muaj pes tsawg leeg thiab ib puag ncig nyob rau hauv uas nws yog siv. Thaum 304 stainless hlau yog qhov kev xaiv nrov rau nws qhov kev tiv thaiv corrosion tag nrho, nws yuav tsis yog qhov kev xaiv zoo tshaj plaws rau txhua daim ntawv thov.
Thaum nws los txog rau xeb, 304 stainless hlau tuaj yeem ua me ntsis finicky.
Tshwj xeeb, muaj cov tshuaj los yog dej ntsev tuaj yeem cuam tshuam nws lub peev xwm los tiv thaiv xeb. Thaum raug cov tshuaj hnyav lossis dej ntsev, 304 stainless hlau tuaj yeem ua rau muaj kev tiv thaiv corrosion thiab xeb.
Qhov no yog vim tias cov tshuaj no tuaj yeem rhuav tshem cov txheej txheem ntawm chromium oxide uas tiv thaiv cov hlau los ntawm xeb. Yog tias cov txheej txheem passive raug cuam tshuam, cov hlau yuav raug oxygen thiab noo noo, uas tuaj yeem ua rau xeb tsim.
Txhawm rau tiv thaiv qhov no, nws yog ib qho tseem ceeb uas yuav tsum siv cov qib tsim nyog ntawm cov hlau tsis huv thiab xyuas kom meej tias nws raug ntxuav kom zoo thiab tswj xyuas kom tiv thaiv nws los ntawm cov tshuaj hnyav thiab dej ntsev.
Lub xub ntiag ntawm cov tshuaj los yog dej ntsev cuam tshuam li cas rau xeb ntawm 304 stainless hlau?
Puas yog rusted 304 stainless hlau tseem siv tau rau ntau yam kev siv?
Thaum nws los txog rau rusted 304 stainless hlau, cov lus teb tsis yog ib txwm ncaj nraim. Nws nyob ntawm qhov hnyav ntawm xeb thiab kev thov tshwj xeeb ntawm cov khoom siv.
Feem ntau, cov xeb me me yuav tsis cuam tshuam rau kev ua haujlwm ntawm cov hlau tsis muaj steel, tshwj xeeb tshaj yog tias nws nyob hauv qhov chaw tsis muaj corrosive.
Txawm li cas los xij, hauv cov ntawv thov tseem ceeb dua, xws li kev sib cuag nrog zaub mov lossis tshuaj, txawm tias xeb me tuaj yeem ua rau cov khoom siv tsis tau.
Nyob rau hauv cov ntaub ntawv no, nws yog ib qho tseem ceeb kom huv si huv si thiab kho tej chaw rusted, los yog hloov cov ntaub ntawv tag nrho los xyuas kom meej kev ua tau zoo thiab kev nyab xeeb.
Raws li ib txwm muaj, kev tiv thaiv yog qhov zoo tshaj plaws ntawm kev nqis tes ua, yog li kev saib xyuas tsis tu ncua thiab kev cia kom zoo tuaj yeem pab tiv thaiv xeb thiab txuas ntxiv lub neej ntawm 304 stainless hlau hauv ntau daim ntawv thov.
