Thaum muas lub khob dej stainless hlau, ntau tus neeg siv khoom yuav txhawj xeeb txog seb cov khoom siv stainless hlau siv hauv lub khob puas tau raws li cov qauv, vim tias cov khoom siv stainless hlau sib txawv muaj cov yam ntxwv sib txawv. Raws li tus kws tshaj lij stainless hlau tsim khoom, kuv yuav qhia qee txoj hauv kev los txiav txim siab yam khoom siv stainless hlau siv hauv stainless hlau dej khob los pab cov neeg siv khoom paub xaiv.
1. Kos lub logo stainless hlau:
Txhua yam khoom siv stainless hlau yuav tsum muaj lub logo ntshiab stainless hlau. Feem ntau, stainless hlau dej fwj cim nrog "18/8" lossis "18/10" siv 304 stainless hlau, thaum cov cim nrog "316" qhia tias lawv siv 316 stainless hlau. Cov cim no yog ib txoj hauv kev rau cov tuam txhab lag luam los qhia cov qib ntawm cov hlau tsis muaj steel siv hauv lawv cov khoom.
2. Magnetic test:
Stainless hlau muaj hlau, tab sis qee cov ntaub ntawv stainless hlau muaj cov ntsiab lus hlau tsawg thiab tej zaum yuav tsis yog hlau nplaum. Siv cov cuab yeej ntsuas magnetic, xws li cov hlau nplaum, txuas rau lub khob dej. Yog tias nws tuaj yeem raug adsorbed, nws qhia tau hais tias lub khob dej tsis muaj steel hlau muaj cov ntsiab lus hlau ntau dua thiab tej zaum yuav yog 304 stainless hlau ntau dua.
3. Saib cov xim ntawm cov iav dej:
304 stainless hlau feem ntau yog ci nyiaj hauv cov xim, thaum 316 stainless hlau tuaj yeem muaj qhov ci ntsa iab zoo nkauj ntawm qhov chaw. Los ntawm kev soj ntsuam cov xim ntawm lub khob dej, koj tuaj yeem pib ntsuas cov khoom siv stainless hlau siv.
4. Siv acid-base test:
Siv cov kua txiv hmab txiv ntoo (acidic) thiab baking soda daws (alkaline) thiab siv rau ntawm lub khob dej raws li. Yog tias cov khoom siv stainless hlau yog 304, nws yuav tsum ruaj khov nyob rau hauv qhov kev txiav txim ntawm cov kua qaub; thaum nyob rau hauv qhov kev txiav txim ntawm alkaline kua, stainless hlau cov ntaub ntawv feem ntau yuav tsis hnov. Nco ntsoov tias txoj kev ntsuas no yog qhov zoo tshaj plaws tau txais los ntawm cov tub lag luam ua ntej yuav khoom thiab siv ceev faj kom tsis txhob muaj kev puas tsuaj rau cov khoom.
5. Kev ntsuas kub:
Siv tus pas ntsuas kub ntsuas qhov ntsuas kub ntawm lub khob dej.
316 stainless hlau feem ntau muaj cov khoom siv hluav taws xob zoo dua qub, yog li yog tias lub raj mis dej txias los yog kub ceev hauv lub sijhawm luv luv, cov qib siab ntawm stainless hlau yuav raug siv.
Cov txheej txheem no tuaj yeem pab koj pib txiav txim siab txog qee yam ntawm cov khoom siv stainless hlau siv hauv stainless hlaukhob dej. Tab sis thov nco ntsoov tias qhov tseeb tshaj plaws yog nug cov chaw tsim khoom lossis tus muag khoom, uas feem ntau yuav muab cov ncauj lus kom ntxaws txog cov khoom.
