Aluminium ntawv ci yog ib yam khoom ntawm txhuas dov. Aluminium ntawv ci feem ntau yog hais txog thickness. Hauv kev lag luam, cov khoom siv txhuas uas muaj qhov tuab tsawg dua 0.2 hli feem ntau hu ua aluminium foil. Cov npoo feem ntau yog txiav vertically thiab xa hauv yob. Aluminium ntawv ci yog ib hom mos hlau zaj duab xis. Nws tsis tsuas yog muaj qhov zoo ntawm noo noo-pov thawj, huab cua-tight, lub teeb-shielding, abrasion resistance, fragrance retention, non-toxic thiab tasteless, tab sis kuj vim nws elegant silver-dawb luster, nws yog ib qho yooj yim mus ua cov qauv zoo nkauj thiab xim ntawm ntau yam xim. qauv.
Raws li cov thickness, aluminium ntawv ci tuaj yeem muab faib ua ob chav xoom ntawv, ib qho xoom ntawv ci thiab ntawv ci tuab. Muab ob npaug rau-zero ntawv ci hais txog cov ntawv ci uas muaj ob xoom tom qab tus lej lej thaum nws qhov tuab yog ntsuas hauv mm (xws li thickness<0.01mm); similarly, single-zero foil refers to a foil that has one zero after the decimal point when its thickness is measured in mm. Foil (0.01mm≤thickness<0.1mm); thick foil refers to aluminum foil with a thickness between 0.1mm and 0.2mm.
Feem ntau hais lus, ob daim ntawv xoom yog siv rau kev ntim khoom noj, ntim luam yeeb, hluav taws xob kho qhov muag, thiab lwm yam.; ib qho xoom ntawv ci yog siv rau qee qhov ntim khoom noj, ntim tshuaj, hluav taws xob hluav taws xob tiv thaiv hluav taws xob, ntawv ci cua txias, thiab lwm yam; tuab ntawv ci yog tsuas yog siv rau cov cua txias ntawv ci, Thawv ntawv ci, architectural kho kom zoo nkauj thiab muaj kev siv.
Txheej txheem ntau lawm
Cov txheej txheem aluminium ntawv ci yog cov khoom siv txhuas nrog cov txheej txheem ua haujlwm ntau tshaj plaws, qhov tsawg tshaj plaws thickness, thiab qhov nyuaj tshaj plaws hauv kev lag luam aluminium. Tam sim no, muaj ob txoj kev siv thev naus laus zis hauv kev lag luam: (1) Ingot kub dov txoj kev; (2) Ob chav-roller casting thiab dov txoj kev.
Ingot kub dov txoj kev
Ua ntej, cov txhuas yaj yog cam khwb cia rau hauv lub tiaj tus ingot, thiab tom qab ntawd tom qab homogenization, kub dov, txias dov, intermediate annealing thiab lwm yam txheej txheem, nws yog txuas mus rau txias dov rau hauv lub phaj nrog ib tug tuab ntawm txog {{0 }}}.4 ~ 1.0 hli raws li cov ntawv ci dawb (casting → kub dov) Billet → txias dov → foil dov).
Nyob rau hauv ingot kub dov txoj kev, lub kub dov billet yog thawj milled kom tshem tawm qhov tsis xws luag xws li oxide txheej thiab impurities nyob rau saum npoo ntawm lub ingot, thiab ces lub microstructure ntawm lub ingot yog ua ntau uniformity los ntawm homogenization, thiab ces kub dov. , txias dov thiab nruab nrab Tom qab ntau cov txheej txheem xws li annealing thiab recrystallization, cov txheej txheem sab hauv cov qauv sib xws thiab cov nplej loj ntawm cov pob zeb tau zoo tuaj. Yog li ntawd, kub-kuav los tiag billets feem ntau yog zoo dua thiab yog haum rau high-zoo ob-zero txhuas ntawv ci thiab sib sib zog nqus ua. Cov khoom siv aluminium foil. Txawm li cas los xij, qhov kub-dov blanks muaj teeb meem xws li pob ntseg tawm los, yooj yim tawg, thiab qhov chaw deformation tsis sib xws thaum lub sij hawm sib sib zog nqus nqus cov txheej txheem, uas txwv kev txhim kho ntawm cov txiaj ntsig zoo ntawm aluminium ntawv ci.
Ob-yob casting txoj kev
Piv nrog rau txoj kev ingot kub dov, cov txheej txheem ntws ntawm kev tsim cov ntawv txhuas blanks los ntawm txoj kev cam khwb cia-dov yog qhov yooj yim; Tsis tas yuav mus dhau cov txheej txheem nyuaj xws li ingot melting, milling, homogenization thiab kub dov, tab sis cov txhuas yaj yog nchuav ncaj qha. Nkag mus rau ob lub rotating casting rollers (crystallizer), thiab ua kom tiav cov txheej txheem solidification thiab kub dov ib txhij nyob rau hauv lub casting thiab dov cheeb tsam nyob rau hauv 2 mus rau 3 vib nas this kom tau ib tug phaj nrog ib tug tuab ntawm 4 mus rau 7 hli. Zoo ib yam li kub-dov txhuas ntawv ci billets, cam khwb cia dov daim hlau kuj yuav tsum tau mus los ntawm ib tug series ntawm txias dov thiab intermediate annealing txheej txheem, thiab thaum kawg dov mus rau hauv 0.3 ~ 0.7 hli tuab daim hlau raws li aluminium foil billets.
