Qhov sib txawv tseem ceeb ntawm cov tawv anodised thiab cam khwb cia hlau yog qhov nyuaj anodized hlau muaj cov khoom tsis-stick, whereas cam khwb cia hlau muaj qhov ruaj khov, pheej yig, thiab sib npaug ntawm cov hlau qhov chaw.
Iron yog cov hlau tseem ceeb hauv kev lag luam thiab hauv kev tsim cov khoom siv hlau sib txawv xws li cookware. Hard anodized hlau thiab cam khwb cia hlau feem ntau yog siv los ua cookware hlau vim lawv cov khoom muaj txiaj ntsig.
Dab tsi yog Hard Anodised Iron?
Hard anodised hlau yog tsim los ntawm cov txheej txheem electrolytic uas muaj txiaj ntsig zoo hauv kev ua kom cov tuab ntawm cov txheej txheem oxide nyob rau saum npoo ntawm cov hlau. Nws yog txheej txheem electrolytic passivation. Peb hu nws ua txheej txheem anodizing vim hais tias, nyob rau hauv cov txheej txheem no, peb kho cov hlau raws li anode electrode ntawm ib tug electrolytic cell. Cov txheej txheem no tseem ceeb heev vim tias nws tuaj yeem ua rau muaj kev tiv thaiv corrosion thiab hnav. Tsis tas li ntawd, nws muab adhesion zoo dua rau cov xim primers thiab cov nplaum. Ntxiv mus, peb tuaj yeem siv cov yeeb yaj kiab anodic hauv ntau yam tshuaj pleev ib ce nrog rau cov tuab, ntxeem tau txheej (uas tuaj yeem nqus cov xim nrog cov txheej pob tshab) uas tuaj yeem ntxiv qhov cuam tshuam ntawm lub teeb yoj cuam tshuam.
Daim duab 01: Cov Khoom Siv Hlau Anodized
Feem ntau, cov txheej txheem anodizing tuaj yeem hloov qhov kev ntxhib los mos (microscopic) ntawm qhov chaw ntawm cov hlau thiab cov qauv siv lead ua ntawm cov hlau uas nyob ze ntawm qhov chaw. Feem ntau, cov txheej tuab tau los ntawm txoj kev no yog ntxeem tau. Nyob rau hauv tas li ntawd, peb yuav tsum tau siv lub sealing kauj ruam kom tau corrosion kuj. E.g. anodized aluminium nto yog ib qho nyuaj tshaj li ib txwm txhuas hlau qhov chaw, tab sis peb yuav tsum tau siv cov sealing agents los tiv thaiv lawv ntawm corrosion.
Cast Iron yog dab tsi?
cam khwb cia hlau yog cov hlau uas peb tuaj yeem muab pov rau hauv pwm. Nws yog ib qho nyuaj thiab kuj nkig. Nws muaj cov hlau, carbon, silicon, thiab manganese, nrog rau cov kab ntawm leej faj thiab phosphorous ib yam nkaus. Tus nqi ntawm carbon nyob rau hauv no alloy yog siab heev piv rau steel. Tsis tas li ntawd, nws muaj ntau npaum li cas ntawm silicon (1-3%) yog li, nws yog ib qho alloy ntawm hlau-carbon-silicon. Tsis tas li ntawd, nws muaj qhov kub thiab txias tsawg dua li lwm cov hlau alloys.
Cov alloy no solidifies raws li ib tug heterogeneous alloy. Nws tsis yog ductile; yog li, nws tsis haum rau dov. Tsis tas li ntawd, nws tsis hnov mob nrog cov khoom molding thaum melted thiab poured. Qhov laj thawj tseem ceeb rau qhov muaj txiaj ntsig ntawm cov hlau no yog nws qhov qis melting point. Qhov qis melting point no ua rau zoo fluidity, castability, zoo heev machinability, tsis kam mus deformation, thiab hnav tsis kam.
Daim duab 02: Cam khwb cia hlau
Muaj ntau hom cam khwb cia hlau raws li microstructure ntawm cov hlau. Cov hom no yog raws li nram no:
- Grey cam khwb cia hlau
- cam khwb cia hlau
- Malleable cam khwb cia hlau
- cam khwb cia hlau
Peb siv cam khwb cia hlau rau engineering thiab kev tsim qauv vim nws ruaj khov. Yog li ntawd, nws muaj txiaj ntsig zoo hauv cov kav dej, cov tshuab, thiab cov khoom siv hauv tsheb, xws li lub tog raj kheej taub hau (kev siv qis), lub tog raj kheej thaiv, thiab cov rooj plaub gearbox. Ntxiv mus, nws tiv taus kev puas tsuaj los ntawm oxidation.
Qhov txawv ntawm Hard Anodised thiab Cast Iron yog dab tsi?
Iron yog cov hlau tseem ceeb hauv kev lag luam thiab hauv kev tsim cov khoom siv hlau sib txawv xws li cookware. Hard anodized hlau thiab cam khwb cia hlau yog ob qho kev siv tseem ceeb ntawm cov hlau hlau. Qhov sib txawv tseem ceeb ntawm cov tawv anodised thiab cam khwb cia hlau yog qhov nyuaj anodized hlau muaj cov khoom uas tsis yog-stick, whereas cam khwb cia hlau muaj qhov ruaj khov, pheej yig, thiab sib npaug ntawm cov hlau qhov chaw.
Daim duab hauv qab no qhia txog qhov sib txawv ntawm cov tawv anodised thiab cam khwb cia hlau hauv daim ntawv tabular.
Summary – Hard Anodised vs Cast Iron
Hard anodised hlau thiab cam khwb cia hlau yog qhov tseem ceeb hauv kev tsim cov khoom noj khoom haus. Qhov sib txawv tseem ceeb ntawm cov tawv anodised thiab cam khwb cia hlau yog qhov nyuaj anodized hlau muaj cov khoom uas tsis yog-stick, whereas cam khwb cia hlau muaj qhov ruaj khov, pheej yig, thiab sib npaug ntawm cov hlau qhov chaw.
