Stainless hlau yog cov khoom siv nrov paub txog nws cov kav ntev, corrosion kuj, thiab zoo nkauj. Nws yog siv rau hauv ntau yam kev siv, los ntawm cov khoom siv hauv chav ua noj mus rau cov khoom siv hauv tsev. Txawm li cas los xij, nrog kev loj hlob ntawm cov hlau sib txawv thiab cov alloys ntawm kev ua lag luam, kev txheeb xyuas cov hlau tsis zoo tuaj yeem ua rau qee zaum nyuaj. Hauv tsab xov xwm no, peb yuav tshawb nrhiav txoj hauv kev zoo los pab koj txheeb xyuas cov hlau tsis muaj steel thiab nkag siab txog nws cov khoom tshwj xeeb.
Nkag siab Stainless Hlau
Ua ntej peb delve rau hauv cov txheej txheem kev txheeb xyuas, nws yog ib qho tseem ceeb kom nkag siab tias stainless hlau yog dab tsi. Stainless hlau yog ib qho hlau alloy uas feem ntau yog hlau, chromium, thiab qee zaum nickel thiab lwm yam khoom. Cov ntsiab lus chromium feem ntau yog tsawg kawg yog 10.5%, uas muab cov hlau tsis muaj steel nws cov corrosion kuj. Stainless hlau los ntawm ntau qib, txhua tus muaj cov khoom tshwj xeeb thiab siv, suav nrog 304, 316, thiab 430.
Kev tshuaj xyuas qhov muag
Ib txoj hauv kev yooj yim tshaj plaws los txheeb xyuas cov hlau tsis huv yog los ntawm kev tshuaj xyuas qhov muag. Stainless hlau muaj qhov tshwj xeeb ci ntsa iab hlau uas txawv ntawm lwm cov hlau. Nrhiav ib tug du nto uas qhia txog lub teeb zoo. Txawm li cas los xij, ceev faj vim qee cov hlau kuj tseem muaj qhov ci ci.
Magnet Test
Lwm txoj kev txheeb xyuas cov hlau tsis zoo yog cov hlau nplaum. Txawm hais tias feem ntau cov hlau tsis muaj hlau tsis sib nqus, qee cov qib stainless hlau (xws li 430) yog hlau nplaum. Txhawm rau ua qhov kev sim no, siv cov hlau nplaum thiab saib seb nws lo rau cov hlau. Yog tias cov hlau nplaum tsis lo, nws yog ib qho austenitic stainless hlau (xws li 304 lossis 316). Yog tias nws lo, nws yog ib qho ferritic stainless hlau (xws li 430) lossis lwm cov hlau nplaum.
Kev kuaj dej zoo
Stainless hlau yog lub npe hu rau nws tiv thaiv xeb thiab corrosion. Txhawm rau ua qhov ntsuas dej, tsuas yog tso ob peb tee dej rau saum npoo ntawm cov hlau. Yog tias cov hlaws dej nce thiab tsis sib kis, nws feem ntau yuav tsis muaj steel hlau. Yog tias cov dej sib kis thiab tawm mus, cov hlau yuav tsis yog stainless hlau lossis tsis zoo.
Kev kuaj kos
Kev kuaj khawb kuj tseem tuaj yeem pab txheeb xyuas cov hlau tsis muaj steel. Siv cov khoom ntse, xws li riam los yog ntsia hlau, txhawm rau khawb qhov saum npoo ntawm cov hlau. Stainless hlau yog ib qho nyuaj thiab tsis khawb yooj yim. Yog hais tias lub nto yog khawb los yog puas, nws yog tej zaum tsis stainless hlau thiab tej zaum yuav yog ib tug qis qib alloy.
Kev kuaj tshuaj
Txhawm rau kom paub meej ntxiv, kev kuaj tshuaj tuaj yeem ua tau. Muaj cov kev daws teeb meem tshwj xeeb uas cuam tshuam nrog cov hlau tsis muaj steel los tsim cov xim hloov. Piv txwv li, ib qho tshuaj uas muaj nitric acid tuaj yeem siv rau cov hlau. Yog hais tias nws yog stainless hlau, yuav muaj cov tshuaj tiv thaiv me ntsis, thaum lwm cov hlau yuav corrode los yog discolor.
Kev txheeb xyuas cov hlau tsis huv yog qhov tseem ceeb rau ntau yam kev siv, txawm tias koj tab tom yuav khoom noj khoom haus, cov cuab yeej, lossis cov khoom siv hauv tsev. Los ntawm kev siv kev sib xyaw ua ke ntawm kev kuaj pom, ntsuas hlau nplaum, kuaj dej, kuaj kos, thiab tshuaj ntsuam xyuas tshuaj, koj tuaj yeem txiav txim siab tias cov hlau yog stainless hlau. Kev nkag siab txog cov txheej txheem no yuav tsis tsuas yog pab koj txiav txim siab, tab sis kuj xyuas kom meej tias koj tab tom nqis peev hauv cov ntaub ntawv zoo uas yuav sawv cev rau lub sijhawm. Nco ntsoov, thaum tsis ntseeg, kev sab laj tus kws tshaj lij lossis tus kws tshaj lij cov ntaub ntawv tuaj yeem muab kev lees paub ntxiv hauv koj cov txheej txheem qhia.
