Stainless hlau yuav tsum paub txog peb txhua tus.Hauv peb lub neej, ntau yam yog ua los ntawm stainless hlau.Thaum mus yuav khoom ntawm cov khoom siv stainless hlau hauv tsev, peb tuaj yeem pom ntau tus lej ua ntej lo lus "stainless steel".Cov zauv feem ntau yog 304 thiab 316. Cov lej no txhais li cas?Peb yuav tsum xaiv qhov twg?
Stainless hlau tsis tsuas yog tsis xeb
Peb txhua tus paub tias lub ntsiab ntawm cov hlau yog hlau.Cov tshuaj lom neeg ntawm cov hlau yog cov nquag nquag, thiab nws yooj yim rau chemically hnov mob nrog cov khoom nyob ib puag ncig.Cov tshuaj tiv thaiv feem ntau yog oxidation, qhov twg hlau reacts nrog oxygen nyob rau hauv cov huab cua, uas yog feem ntau hu ua xeb.
Ntxiv qee qhov impurities (tsuas yog chromium) rau cov hlau los tsim cov hlau tsis muaj steel.Tab sis lub peev xwm ntawm stainless hlau tsis yog tsuas yog los tiv thaiv xeb, qhov no tuaj yeem pom los ntawm nws lub npe tag nrho: stainless thiab acid-resistant steel.Stainless hlau tsis tsuas yog tiv taus oxidation, tab sis kuj tiv taus acid corrosion.
Tag nrho cov hlau tsis muaj zog tiv taus oxidation, tab sis hom thiab feem ntawm impurities nyob rau hauv txawv, thiab muaj peev xwm tiv taus acid corrosion kuj txawv (qee zaum peb pom tias cov nto ntawm ib co stainless hlau tseem rusty vim nws yog corroded los ntawm acid). .Txhawm rau kom paub qhov txawv ntawm cov kua qaub tiv thaiv ntawm cov hlau tsis muaj steel, cov neeg tau teev cov qib sib txawv ntawm cov hlau tsis huv.
304 stainless hlau thiab 316 stainless hlau
304 thiab 316 yog cov qib stainless hlau ntau dua hauv peb lub neej.Peb tuaj yeem nkag siab yooj yim xws li: tus lej loj dua, qhov muaj zog ntawm cov kua qaub corrosion tsis kam ntawm stainless hlau.
Muaj cov hlau tsis muaj zog uas tsis tshua muaj zog rau cov kua qaub ntau dua li 304 stainless hlau, tab sis cov hlau tsis muaj hlau tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov khoom noj.Cov khoom noj niaj hnub niaj hnub tuaj yeem corrode stainless hlau.Nws tsis zoo rau cov hlau tsis muaj steel, thiab nws tseem phem dua rau tib neeg lub cev.Piv txwv li, stainless hlau railings siv 201 stainless hlau.
Kuj tseem muaj cov hlau tsis muaj hlau uas tiv taus cov kua qaub ntau dua li 316 stainless hlau, tab sis tus nqi ntawm cov hlau tsis zoo no siab dhau.Tej yam uas tuaj yeem ua rau lawv tsis yooj yim pom hauv lub neej, yog li peb tsis tas yuav nqis peev ntau dhau ntawm qhov no.
Khoom noj khoom haus qib stainless hlau
Ua ntej ntawm tag nrho cov, nyob rau hauv tus txheej txheem, nws tsis tau teev tias qib ntawm stainless hlau yog zaub mov qib stainless hlau.Nyob rau hauv "National Food Safety Standard Stainless Steel Products (GB 9684-2011)", ib tug series ntawm corrosion kuj yuav tsum tau rau cov zaub mov tiv tauj stainless hlau.
Tom qab ntawd, tom qab sib piv cov kev cai no, tib neeg pom tias tus qauv yam tsawg kawg nkaus ntawm stainless hlau uas tuaj yeem ua tau raws li cov kev cai no yog 304 stainless hlau.Yog li muaj cov lus hais tias "304 stainless hlau yog zaub mov qib stainless hlau".Txawm li cas los xij, txhua tus yuav tsum nkag siab ntawm no tias cov lus no tsis raug.Yog tias 304 tuaj yeem tiv tauj nrog cov zaub mov, ces 316 stainless hlau, uas yog resistant rau acid thiab corrosion dua 304 stainless hlau, ib txwm yuav zoo dua li 316 stainless hlau.Lawv ib txwm siv tau rau kev sib cuag zaub mov.
Yog li muaj lus nug kawg: Kuv puas yuav tsum xaiv qhov pheej yig dua 304 rau kev siv hauv tsev lossis tus nqi siab dua 316?
Rau stainless hlau nyob rau hauv dav dav, xws li faucets, dab dej, racks, thiab lwm yam., 304 stainless hlau yog txaus.Rau qee qhov stainless hlau uas nyob ze rau cov khoom noj, tshwj xeeb tshaj yog nrog ntau yam khoom noj, xws li cov tais diav, khob dej, thiab lwm yam, koj tuaj yeem xaiv 316 stainless hlau-304 stainless hlau tiv tauj nrog cov khoom noj siv mis, dej qab zib carbonated, thiab lwm yam., tseem yuav corroded.
