Raws li peb lub hom phiaj yav dhau los ntawm kev siv 304 stainless hlau nyob rau hauv kub khiav sensor sojntsuam mounting, peb tuaj yeem txiav txim siab qhov tseeb ntawm 304 stainless hlau los ntawm ntau yam - qhov ntev mus kom ze, teev hauv qab no los ntawm qhov yooj yim tshaj plaws mus rau qhov nyuaj tshaj plaws:
I. Cov txheej txheem qhia tus kheej yooj yim thiab ceev
Kev Ntsuas Kev Ntsuas: Cov khoom tsim nyog, cov khoom tsim nyog yuav muaj qhov tseeb 304 lossis SUS304 kos rau ntawm qhov chaw. Qhov tsis muaj qhov cim no qhia tau tias muaj cov khoom cuav.
Magnetic Attraction Test: 304 stainless hlau yog austenitic, tsis muaj zog hlau nplaum. Ordinary hlau nplaum muaj zog yuav tsuas tsim ib tug tsis muaj zog attraction. Yog tias nws ruaj khov, nws yuav yog qhov tsawg - cov khoom cuav xws li 201 stainless hlau. Nco ntsoov tias txias - ua haujlwm 304 tuaj yeem pom cov hlau nplaum tsis muaj zog, yuav tsum tau kuaj xyuas siv lwm txoj hauv kev.
Cov Lus Qhia Kom Paub Txog Kev Txiav Txim: Qhov Tseeb 304 muaj ib qho xim matte nyiaj -dawb tiav, du thiab flawless nto, thiab xav tias hnyav dua rau nws ntim. Cov khoom cuav feem ntau pom cov xim xiav xiav, muaj kev cuam tshuam ntau dhau, thiab burrs lossis pinholes ntawm cov npoo.
II. Tsawg-Txoj Kev Ntsuas Tus Nqi Hauv Tsev
Siv cov tshuaj ntsuam xyuas stainless hlau yuav hauv online. Siv ib qho poob rau saum npoo steel thiab tos 2-3 feeb. Qhov tseeb 304 stainless hlau yuav nyob twj ywm silvery-dawb los yog yellowish me ntsis. Yog hais tias nws sai sai tig liab los yog darkens, nws yog cov khoom cuav nrog ntau manganese cov ntsiab lus. Hnav hnab looj tes thaum kuaj kom tsis txhob muaj tawv nqaij sib cuag nrog cov tshuaj.
III. Kev tshaj lij thiab kev xeem qhov tseeb
Siv ib tug handheld spectrometer scan cov khoom. Kev lees paub cov ntsiab lus chromium Ntau dua lossis sib npaug li 18% thiab cov ntsiab lus npib tsib xee Ntau dua lossis sib npaug li 8% ua tiav raws li lub teb chaws tus qauv rau 304 stainless hlau, nws tuaj yeem yog 100% pom tias yog tiag. Xwb, nws tuaj yeem xa mus rau ib tus kws tshaj lij thib peb-chaw kuaj xyuas tog nrog CMA/CNAS kev lees paub rau daim ntawv tshaj tawm kev xeem raug cai.
