Dab tsi yog aluminium foil chemical?
Chemically, aluminium ntawv ci feem ntau yog tsim los ntawm cov khoom txhuas (Al). Cov khoom siv tshuaj lom neeg ntawm cov ntawv txhuas txhuas feem ntau yog vim cov khoom ntawm txhuas nws tus kheej thiab cov txheej txheem tiv thaiv oxide uas tsim rau ntawm nws qhov chaw. Ntawm no yog ib qho kev sib cais:
Elemental Composition
Aluminium (Al):Qhov tseem ceeb ntawm aluminium ntawv ci yog aluminium hlau. Hauv nws daim ntawv dawb huv, txhuas muaj tus lej atomic 13 thiab sawv cev los ntawm lub cim Al.
Oxide Txheej
Aluminium Oxide (Al₂O₃):Thaum txhuas raug rau huab cua, nws reacts nrog oxygen los tsim ib txheej nyias, tiv thaiv aluminium oxide rau ntawm nws qhov chaw. Cov txheej no tiv thaiv ntxiv oxidation thiab corrosion. Cov tshuaj tiv thaiv tuaj yeem sawv cev raws li: 4Al+3O2 → 2Al2O34 Al + 3 O₂ \rightarrow 2 Al₂O₃4Al+3O2 →2Al2O3
Alloying Elements:
Nyob ntawm seb yam tshwj xeeb ntawm aluminium ntawv ci, me me ntawm lwm cov ntsiab lus tuaj yeem muaj los txhim kho qee yam khoom. Common alloying ntsiab muaj xws li:
Manganese (Mn)
Hlau (Fe)
Silicon (Si)
Cov ntsiab lus no feem ntau muaj nyob rau hauv me me thiab tsis cuam tshuam cov tshuaj lom neeg ntawm aluminium ntawv ci tab sis txhim kho nws cov khoom siv kho tshuab.
Chemical Properties:
Corrosion Resistance:Vim lub oxide txheej, aluminium ntawv ci yog heev resistant rau corrosion.
Tsis-Toxicity:Aluminium yog non-toxic, uas ua rau nws haum rau ntim khoom noj.
Reflectivity:Aluminium ntawv ci muaj qhov cuam tshuam siab rau ob qho tib si cua sov thiab lub teeb, ua kom muaj txiaj ntsig zoo hauv thermal rwb thaiv tsev thiab ua noj ua haus.
Vim li cas aluminium foil tsis xeb?
Aluminium ntawv ci tsis xeb vim xeb yog ib hom kev xeb uas tshwm sim nrog hlau thiab nws cov alloys. Kev xeb yog qhov tshwm sim ntawm oxidation ntawm hlau nyob rau hauv lub xub ntiag ntawm dej thiab oxygen, ua rau lub tsim ntawm hlau oxide (xeb). Aluminium, txawm li cas los xij, coj txawv txawv thaum raug huab cua thiab ya raws:
Oxide Txheej Txheej
Thaum txhuas raug rau huab cua, nws sai sai tsim ib txheej nyias ntawm txhuas oxide ntawm nws nto. Cov txheej oxide no nyias nyias, feem ntau tsuas yog ob peb nanometers tuab, tab sis nws yog tuab thiab nruj nreem rau cov hlau nto.
Qhov txheej txheej aluminium oxide no ua haujlwm tiv thaiv kev tiv thaiv, tiv thaiv oxidation ntxiv ntawm cov txhuas hauv qab. Cov txheej txheem no hu ua passivation.
Stable thiab Tsis-porous
Tsis zoo li xeb, uas tuaj yeem flake tawm thiab nthuav tawm ntau cov hlau rau cov ntsiab lus, aluminium oxide txheej yog ruaj khov thiab tsis ntxeem tau. Qhov no txhais tau tias nws zoo seals nto thiab tiv thaiv corrosion ntxiv.
Corrosion Resistance
Aluminium lub ntuj oxide txheej muab kev tiv thaiv corrosion zoo heev hauv ntau qhov chaw. Qhov no suav nrog kev tiv thaiv corrosion los ntawm huab cua, dej, thiab ntau yam tshuaj.
Tsis-Reactivity
Aluminium yog tsis tshua muaj reactive tshaj hlau nrog dej thiab oxygen, uas ntxiv yuav txo tau ntawm corrosion.
