1. Tshuaj muaj pes tsawg leeg
Cov qib alloy ntawm aluminium ntawv ci rau cov cua sov sib pauv fins feem ntau suav nrog 1100, 1200, 8011, thiab lwm yam. Los ntawm qhov pom ntawm kev siv, cov tshuab cua txias tsis muaj kev txwv nruj ntawm cov tshuaj muaj pes tsawg leeg ntawm aluminium heat exchanger fins. Yog tsis muaj kev kho deg, 3A21 txhuas alloy muaj qhov zoo corrosion kuj, siab mechanical zog xws li lub zog thiab elongation, thiab siab hardness. Qhov twg alloy xaiv tsuas yog nyob ntawm qhov kawg ntawm cov khoom siv kho tshuab uas cov khoom tuaj yeem ua tiav thiab qhov nyuaj ntawm cov txheej txheem ntsaum. Piv txwv li, lub dov ntawm 1100 aluminium alloy nrog ntau dua purity yog yooj yim dua, thaum uas ntawm 8011 alloy yog nyuaj dua.
2. Mechanical zog
Cov khoom siv tshuab feem ntau yog xa mus rau lub zog tensile, elongation thiab cupping tus nqi ntawm aluminium ntawv nyiaj. Los ntawm qhov kev xav ntawm kev siv, nws cia siab tias qhov siab dua ntawm peb qhov ntsuas, qhov zoo dua, tab sis raws li cov khoom nws tus kheej muaj kev txhawj xeeb, peb qhov ntsuas no yog qhov tsis sib xws, uas yog, thaum lub zog tensile ntawm aluminium ntawv ci yog qhov siab, elongation Performance index yuav txo; thiab Thaum nce qhov elongation ntawm aluminium ntawv ci, nws yuav ua rau txo qis zog tensile. Yog li ntawd, hauv kev siv tswv yim, feem ntau tus nqi nruab nrab ntawm cov khoom siv kho tshuab feem ntau yog siv, thiab qhov tshwj xeeb ntawm lub zog thiab plasticity qhov tseem ceeb muaj feem xyuam rau lub stamping tuag thaum lub sij hawm sib hloov fin. Feem ntau, cov txheej txheem xuas nrig ntaus ntawm cov cua sov sib pauv fins tau muab faib ua hom stretching thiab tsis-stretching hom. Stretch-type dies xav tau cov yas zoo dua ntawm aluminium ntawv ci, uas yog, ntau dua elongation, thiab tus txheeb ze zog tus nqi yuav qis dua; thaum uas tsis yog-stretch tuag kuj yuav tsum muaj zog dua ntawm aluminium ntawv ci, thiab plasticity yog qhov taw qhia thib ob. Muaj ntau yam uas cuam tshuam rau cov khoom siv hluav taws xob ntawm aluminium ntawv ci, feem ntau yog cov tshuaj lom neeg muaj pes tsawg leeg thiab kev siv tshuab ntawm aluminium ntawv ci. Raws li lub zog thiab plasticity ntawm aluminium ntawv nyiaj muaj kev txhawj xeeb, los ntawm kev kho cov tshuaj muaj pes tsawg leeg los yog hloov cov txheej txheem ua thiab tsis, cov yas los yog lub zog ntawm cov khoom tuaj yeem hloov pauv nyob rau hauv qee qhov ntau thaum khaws ib sab tsis hloov. Qhov ntawd yog hais tias, qhov sib piv tus nqi ntawm aluminium foil lub zog thiab plasticity tuaj yeem hloov pauv los ntawm kev hloov kho cov tshuaj muaj pes tsawg leeg thiab kev siv tshuab.
Raws li qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv ntawm cov khoom siv hluav taws xob sib txawv, muaj peb lub ntsiab lus siv ntawm aluminium ntawv ci: H22, H24, thiab H26. Txhua lub xeev sib raug rau qee yam ntawm lub zog thiab plasticity. Kev txiav txim los ntawm cov xwm txheej tam sim no ntawm kev lag luam aluminium hauv tsev, tsis muaj tus qauv zoo sib xws rau ntau yam khoom siv hauv txhua lub xeev. Nyob rau tib lub sij hawm, nyob rau hauv kev siv tswv yim, ntau yam ntawm txhua yam khoom ntawm txhua lub xeev yog dav heev, thiab cov khoom siv kho tshuab tsis tuaj yeem tswj tau zoo kom txaus siab rau cov neeg siv khoom. Table 1 qhia txog lub xeev thiab cov khoom siv ntawm cov khoom siv aluminium foil alloys rau cov cua sov exchangers.
