Khoom noj khoom haus-qib stainless hlau hais txog cov khoom siv stainless hlau uas ua raws li National Standard of the People's Republic of China / Sanitary Standards for Stainless Steel Utensil Containers GB 9684-88. Nws yog cov hmoov txhuas thiab cov ntsiab lus chromium qis dua li ntawm cov hlau tsis huv.
Thaum cov hlau hnyav uas cov khoom siv hlau tsis muaj hlau txav tau siv ntau tshaj qhov txwv, nws yuav ua rau tib neeg noj qab haus huv. Vim li no, National Food Safety Standard of "Stainless Steel Products" (GB9684-2011) tau teeb tsa cov qauv nruj rau nag lossis daus ntawm ntau yam hlau hnyav xws li chromium, cadmium, nickel, thiab txhuas hauv cookware. Ib qho laj thawj yog vim li cas nrog qhov nce ntawm manganese cov ntsiab lus hauv cov hlau tsis muaj steel, muaj kev poob haujlwm xws li corrosion kuj thiab xeb kuj ntawm lub cooker. Thaum cov ntsiab lus manganese nce mus txog ib qho nqi, cov khoom no tsis tuaj yeem siv los ua lub cooker lossis tsis tuaj yeem hu ua stainless hlau cooker. Tab sis txawm tias muaj cov ntsiab lus manganese siab, feem ntau tsis muaj kev cuam tshuam rau kev noj qab haus huv. 304 stainless hlau yog cov hlau tsis muaj steel ntau heev, tseem hu ua 18-8 stainless hlau hauv kev lag luam. Nws cov corrosion kuj zoo dua li 430 stainless hlau, siab corrosion kuj, thiab kub-resistant, kev ua tau zoo, yog li nws yog dav siv nyob rau hauv kev lag luam, rooj tog kho kom zoo nkauj, thiab kev kho mob kev lag luam, piv txwv li, ib co zoo stainless hlau tableware, chav dej, khoom siv hauv chav ua noj.
Yuav kom tswj tau qhov kev tiv thaiv corrosion ntawm cov hlau tsis huv, cov hlau yuav tsum muaj ntau dua 17% chromium thiab ntau dua 8% npib tsib xee. Hauv kev sib piv, 201, 202 stainless hlau (feem ntau hu ua siab manganese steel) feem ntau yog siv rau hauv cov khoom lag luam thiab tsis tuaj yeem siv los ua tableware, vim hais tias: Manganese cov ntsiab lus tshaj tus qauv, kev noj ntau dhau ntawm manganese hauv tib neeg lub cev yuav ua rau muaj kev puas tsuaj. lub paj hlwb.
Nyob rau hauv lub neej txhua hnub, peb muaj ib tug heev tshwm sim ntawm kev tiv tauj stainless hlau cov khoom, thiab stainless hlau hluav taws xob kettles yog ib tug ntawm lawv. Nws yog qhov nyuaj rau kev paub qhov twg yog "201"? Dab tsi yog "304"?
Txhawm rau paub qhov txawv ntawm cov khoom siv stainless hlau sib txawv, txoj hauv kev hauv chav kuaj yog tsuas yog txhawm rau txheeb xyuas cov khoom muaj pes tsawg leeg. Muaj qhov sib txawv tseem ceeb hauv cov hlau sib xyaw ntawm cov khoom sib txawv ntawm cov hlau tsis muaj steel. Rau cov neeg siv khoom zoo tib yam, txoj kev no yog kev tshaj lij thiab tsis tsim nyog, thiab qhov tsim nyog tshaj plaws yog siv 304 manganese cov ntsiab lus kuaj tus neeg sawv cev. Tsuas yog yuav tsum tau poob rau saum npoo kom paub seb cov khoom puas muaj cov ntsiab lus manganese tshaj tus qauv, yog li qhov txawv ntawm 201 stainless hlau thiab 304 stainless hlau. Thiab rau qhov sib txawv ntawm 304 stainless hlau zoo tib yam thiab cov zaub mov-qib stainless hlau, yuav tsum tau kuaj xyuas kom ntxaws ntxiv kom paub qhov txawv. Tab sis peb yuav tsum paub tias cov khoom noj khoom haus-qib stainless hlau yog qhov nruj tshaj plaws, thaum kev lag luam stainless hlau yog qhov yooj yim dua.
cov khoom uas ua tau raws li lub teb chaws GB9684 daim ntawv pov thawj tus qauv thiab tuaj yeem nkag mus rau hauv cov zaub mov tiag tiag yam tsis ua rau muaj kev puas tsuaj rau lub cev. GB9864 stainless hlau yog cov khoom siv stainless hlau uas ua tau raws li lub teb chaws GB9684 daim ntawv pov thawj, yog li GB9864 stainless hlau yog cov zaub mov qib stainless. Tib lub sijhawm, lub npe hu ua 304 stainless hlau tsis tas yuav tsum tau lees paub los ntawm lub teb chaws tus qauv GB9684. 304 stainless hlau tsis sib npaug rau cov zaub mov qib stainless hlau. 304 stainless hlau tsis yog tsuas yog siv hauv chav ua noj xwb tab sis kuj siv dav hauv kev lag luam. Thaum lub sijhawm yuav khoom, cov khoom tsis tu ncua yuav raug cim nrog "khoom noj khoom haus qib 304 stainless hlau" nyob rau saum npoo thiab sab hauv phab ntsa ntawm cov khoom, thiab cov khoom cim nrog "qib zaub mov-GB9684" muaj kev nyab xeeb dua.
