Kev siv ntau ntawm cov khoom siv hlau tsis zoo yog qhov hloov pauv hauv chav ua noj, lawv zoo nkauj, ruaj khov, yooj yim los ntxuav, thiab ncaj qha hloov xim thiab kev xav ntawm chav ua noj. Yog li ntawd, qhov pom kev ib puag ncig ntawm chav ua noj tau zoo heev, thiab nws tsis tsaus thiab ntub, thiab nws yog qhov tsaus ntuj.
Txawm li cas los xij, muaj ntau hom stainless hlau, thiab qhov sib txawv ntawm lawv tsis yog me me. Qee lub sij hawm, cov lus nug txog kev nyab xeeb tau hnov, thiab nws yog ib qho teeb meem xaiv.
Tshwj xeeb tshaj yog thaum nws los txog rau lub lauj kaub, tais diav thiab lwm yam khoom siv uas ncaj qha nqa cov khoom noj, cov khoom yuav nkag siab dua. Yuav ua li cas paub qhov txawv lawv?
Stainless hlau yog dab tsi?
Qhov tshwj xeeb ntawm stainless hlau yog txiav txim los ntawm ob lub ntsiab lus, uas yog chromium thiab npib tsib xee. Yog tsis muaj chromium, nws tsis yog stainless hlau, thiab tus nqi ntawm nickel txiav txim siab tus nqi ntawm stainless hlau.
Stainless hlau muaj peev xwm tswj tau cov luster nyob rau hauv cov huab cua thiab tsis xeb vim hais tias nws muaj ib co ntawm cov chromium alloy ntsiab (tsis tsawg tshaj li 10.5%), uas muaj peev xwm tsim ib tug oxide zaj duab xis nyob rau saum npoo ntawm cov hlau uas yog insoluble nyob rau hauv tej yam xov xwm.
Tom qab ntxiv npib tsib xee, qhov kev ua tau zoo ntawm cov hlau tsis muaj zog ntxiv, thiab nws muaj cov tshuaj lom neeg ruaj khov hauv huab cua, dej thiab chav dej, thiab nws kuj muaj kev ruaj ntseg txaus nyob rau hauv ntau cov kev daws teeb meem ntawm cov kua qaub, alkalis thiab ntsev, txawm tias nyob rau hauv qhov kub thiab txias. Tsis tshua muaj kub ib puag ncig, nws tseem tuaj yeem tswj nws cov corrosion kuj.
Raws li microstructure, stainless hlau muab faib ua martensitic, austenitic, ferritic thiab duplex stainless hlau. Austenite muaj cov yas zoo, tsis muaj zog, qee qhov toughness, yooj yim ua thiab sib sau, thiab tsis muaj ferromagnetic zog.
Austenitic stainless hlau tau tawm hauv lub teb chaws Yelemees xyoo 1913, thiab ib txwm ua lub luag haujlwm tseem ceeb tshaj plaws hauv stainless hlau. Nws cov khoom siv thiab kev siv nyiaj txog li 70% ntawm tag nrho cov khoom tsim thiab siv cov hlau tsis muaj steel. Kuj tseem muaj cov qib steel feem ntau, yog li feem ntau ntawm cov hlau tsis muaj steel koj pom txhua hnub yog austenitic stainless hlau.
Lub npe nrov 304 steel yog austenitic stainless hlau. Cov qauv hauv Suav teb dhau los yog 0Cr19Ni9 (0Cr18Ni9), uas txhais tau hais tias nws muaj 19% ntawm Cr (chromium) thiab 9% ntawm Ni (nickel). 0 txhais tau tias carbon cov ntsiab lus <= 0.07%.
Qhov zoo ntawm kev sawv cev ntawm Suav teb tus qauv yog tias cov ntsiab lus muaj nyob rau hauv stainless hlau yog qhov tseeb ntawm ib nrais muag. Raws li 304, 301, 202, thiab lwm yam, cov no yog cov npe ntawm Tebchaws Meskas thiab Nyij Pooj, tab sis tam sim no txhua tus tau siv lub npe no.
Patented trademark Cromargan 18-10 rau WMF lauj kaub stainless hlau
Peb feem ntau pom cov khoom siv hauv chav ua noj uas cim nrog cov lus 18-10 thiab 18-8. Hom kev cim no qhia txog qhov feem ntawm chromium thiab npib tsib xee hauv stainless hlau. Qhov kev faib ua feem ntawm nickel yog siab dua thiab qhov xwm txheej ruaj khov dua.
18-8 (nickel tsis tsawg dua 8) sib raug rau 304 steel. 18-10 (nickel tsis pub tsawg tshaj 10) sib raug rau 316 steel (0Cr17Ni12Mo2), uas yog hu ua kev kho mob stainless hlau.
304 steel tsis yog khoom kim heev, tab sis nws tsis yog pheej yig
Qhov kev xav tias austenitic 304 stainless hlau yog high-end yog vim Xiaomi, uas tau ntim cov khoom siv niaj hnub niaj hnub rau ntau xyoo rau hauv cov khoom siv high-tech.
Nyob rau hauv lub chav ua noj txhua hnub ib puag ncig, corrosion kuj thiab kev nyab xeeb ntawm 304 yog kiag li txaus. Qhov siab tshaj 316 (0Cr17Ni12Mo2) yog siv rau hauv tshuaj, kev kho mob thiab lwm yam kev lag luam, nrog rau cov khoom siv tshuaj ruaj khov thiab ntau dua corrosion.
Austenitic 304 steel muaj lub zog qis dua thiab feem ntau yog siv hauv cov thawv hauv chav ua noj, thaum riam siv cov khoom siv tawv martensitic stainless hlau (420, 440), uas tsis muaj xeb tsis kam.
Yav dhau los, nws tau xav tias nws yuav ua rau muaj teeb meem, feem ntau yog 201, 202 thiab lwm yam manganese-muaj stainless hlau. 201 thiab 202 stainless hlau yog cov khoom qis tshaj plaws nyob rau hauv stainless hlau, thiab 201 thiab 202 yog tsim los hloov ib feem ntawm 304 stainless hlau. Yog vim li cas yog tias piv nrog npib tsib xee, manganese yog pheej yig dua. Cr-nickel-manganese austenitic stainless hlau xws li 201 thiab 202 yog ib nrab ntawm tus nqi ntawm 304 steel.
Yog lawm, 304 steel nws tus kheej tsis kim li nws yog, txog 6 lossis 7 yuan ib catty, thiab 316 steel thiab 11 yuan ib catty. Tau kawg, cov khoom siv tus nqi feem ntau tsis yog qhov tseem ceeb ntawm cov khoom kawg. Imported stainless hlau cookware yog kim heev, tsis yog tag nrho vim cov ntaub ntawv zoo.
Chav tsev nqi ib tuj ntawm steelmaking cam khwb cia hlau tsuas yog 1/25 ntawm chromium thiab 1/50 ntawm nickel. Ntawm cov nqi uas tsis yog cov txheej txheem annealing, tus nqi raw khoom ntawm austenitic stainless hlau yog pom tseeb ntau dua li ntawm martensite thiab hlau tsis muaj nickel. Khoom stainless hlau. 304 steel yog qhov zoo tib yam tab sis tsis pheej yig, yam tsawg kawg ntawm cov nqi hlau nyoos.
Raws li cov qauv hauv tebchaws tam sim no, koj tsis tuaj yeem paub tias tus qauv twg siv tsis tau hauv chav ua noj
Lub teb chaws qub tus qauv GB9684-1988 qhia tias cov zaub mov-qib stainless hlau muab faib ua ntim thiab cov tais diav. , Martensitic stainless hlau (0Cr13, 1Cr13, 2Cr13, 3Cr13) yuav tsum tau siv. "
Yooj yim yooj yim, ib saib ntawm cov qauv steel thiab koj paub tias cov khoom siv twg tuaj yeem siv rau hauv kev ua zaub mov, ntim khoom, cutlery. Obviously, lub teb chaws tus qauv nyob rau lub sij hawm ntawd yeej ncaj qha txheeb xyuas 304 steel li zaub mov-qib stainless hlau.
Txawm li cas los xij, lub teb chaws tus qauv rov muab dua tom qab - National Food Safety Standard for Stainless Steel Products GB 9684-2011 tsis tau teev cov qauv lawm, thiab tib neeg tsis tuaj yeem txiav txim ncaj qha txog qib zaub mov ntawm tus qauv. Nws tsuas yog hais nyob rau hauv dav dav:
"Tableware ntim, khoom noj khoom haus thiab cov cuab yeej ua haujlwm, thiab cov khoom tseem ceeb ntawm cov khoom siv yuav tsum tau ua los ntawm cov khoom siv stainless hlau uas ua tau raws li cov qauv hauv lub tebchaws, xws li austenitic stainless hlau, austenitic ferritic stainless hlau, thiab ferritic stainless hlau; tableware thiab khoom noj khoom haus ntau lawm machinery Martensitic stainless hlau kuj yuav siv tau rau lub ntsiab lub cev ntawm cov khoom, xws li drilling thiab sib tsoo cov cuab yeej. "
Nyob rau hauv lub teb chaws tus qauv tshiab, nag lossis daus ntawm cov khoom siv hlau yog siv los txiav txim seb tus qauv puas ua tau raws li qhov ntsuas lub cev thiab tshuaj.
Qhov no txhais tau hais tias rau cov neeg zoo tib yam, nws yog ib qho nyuaj rau kev paub qhov txawv ntawm cov khoom noj khoom haus qib stainless hlau, zoo li txhua yam tuaj yeem ua tau, tsuav yog tsis muaj teeb meem.
Kuv qhia tsis tau, kuv yuav xaiv li cas?
Kev txhawj xeeb txog kev nyab xeeb ntawm stainless hlau yog manganese. Yog tias kev noj cov hlau hnyav xws li manganese ntau dhau ntawm cov qauv, yuav muaj qee yam kev puas tsuaj rau lub paj hlwb, xws li kev nco thiab tsis muaj zog.
Yog li nws puas yuav ua rau muaj tshuaj lom vim yog siv cov khoom siv stainless hlau xws li 201 thiab 202? Cov lus teb yog vague.
Thawj yog qhov tsis muaj ntaub ntawv pov thawj hauv lub neej tiag tiag. Tsis tas li ntawd, nyob rau hauv txoj kev xav, tsis muaj kev ntseeg siab.
Muaj ib txoj kab classic hauv cov kev sib tham no: tham txog toxicity yam tsis muaj koob tshuaj yog hooliganism.
Zoo li ntau lwm yam, tus txiv neej yog inseparable los ntawm manganese, tab sis yog hais tias nws absorbs ntau dhau lawm, nws yuav ua rau muaj xwm txheej. Rau cov neeg laus, "qhov txaus" ntawm manganese yog 2-3 mg ib hnub twg hauv Tebchaws Meskas thiab 3.5 mg hauv Suav teb. Rau qhov txwv siab, cov qauv tsim los ntawm Tuam Tshoj thiab Tebchaws Meskas yog nyob ib ncig ntawm 10 mg ib hnub. Raws li cov xov xwm tshaj tawm, cov manganese tau txais ntawm cov neeg nyob hauv Suav yog kwv yees li 6.8 mg ib hnub, thiab tseem tau tshaj tawm tias manganese precipitated los ntawm 201 steel tableware yog qhov tsis txaus ntseeg thiab yuav tsis tshua hloov tib neeg cov manganese kom tsawg.
Cov koob tshuaj no tau txais li cas, lawv puas yuav hloov pauv yav tom ntej, thiab kev noj thiab nag lossis daus los ntawm cov xov xwm tshaj tawm yuav ua rau tsis ntseeg. Yuav ua li cas txiav txim rau lub sijhawm no?
