Nws to taub tias cov khoom lag luam txhuas feem ntau suav nrog cov khoom lag luam zoo txhuas (mos txhuas) thiab cov khoom siv txhuas (txhuas tawv). Cov ntaub ntawv yog aluminium thiab txhuas alloys.
Cov xim saum npoo tuaj yeem faib ua dawb, aluminium cookware teeb lub teeb daj thiab lwm yam xim. Cov txhuas dawb cov khoom lag luam tau muab faib ua cov cuam thiab ruaj khov. Qhov saum npoo ntawm cov cam khwb cia txhuas cov khoom lag luam tau ua tsheb polished thiab mechanically polished, thiab saum npoo yog dawb, txhuas cookware teeb tab sis cov qauv hlau yog xoob thiab muaj qee yam casting tsis xws luag.
Qhov saum npoo ntawm cov khoom sib tw ntawm aluminium yog whitewashed, aluminium cookware teev sanded thiab mechanically polished. Qhov saum npoo yog ntuj oxide zaj duab xis nrog tuab ntawm tsuas yog 0.01-0.15 μm, uas yog nyias thiab tsis sib xws, txhuas cookware teeb thiab yooj yim mechanically khawb lossis hnav. Cov khoom siv txhuas daj daj yog cov khoom lag luam uas tau muab tso ua kom pom lub teeb daj cov pa oxide zaj duab xis rau saum npoo av.
Cov oxide zaj duab xis feem ntau 5-20μm tuab, aluminium cookware teeb tsa zoo ib yam thiab ntom ntom, thiab zaj duab xis yuav tsis puas nyob rau hauv 100 vib nas this raws li kev ua ntawm alkali muaj zog. Yog li no, txhuas cookware teeb lub teeb daj aluminium khoom yog qhov zoo tshaj plaws. Lawv zoo nkauj, aluminium cookware teeb yooj yim tshem tawm av, muaj zog corrosion tsis kam, thiab muaj zog hnav tsis kam.
