Classification thiab dov yam ntxwv ntawm aluminium ntawv ci
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 tsis kam, fragrance retention, non-toxic thiab tasteless, tab sis kuj vim nws elegant silver-dawb luster, nws yog ib qho yooj yim rau txheej txheem zoo nkauj qauv 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 cua txias ntawv ci, Thawv ntawv ci, architectural kho kom zoo nkauj thiab muaj kev siv.
Hauv kev tsim cov ntawv ci ob npaug, qhov dov ntawm aluminium ntawv ci muab faib ua peb txheej txheem: ntxhib dov, nruab nrab dov thiab ua tiav dov. Los ntawm kev siv thev naus laus zis, nws tuaj yeem sib cais raws li qhov tuab ntawm qhov tawm ntawm dov. Txoj kev faib tawm dav dav yog tias qhov tawm thickness ntau dua Los yog sib npaug rau {{0}}}05mm yog qhov ntxhib dov, qhov tawm thickness ntawm 0.013 thiab 0.05 yog nruab nrab dov, thiab ib qho khoom tiav thiab ob chav dov tiav cov khoom nrog tawm thickness tsawg dua 0.013mm yog tiav dov. Cov yam ntxwv dov ntawm ntxhib-dov aluminium phaj thiab strips zoo ib yam. Lub thickness tswj tsuas yog nyob ntawm lub dov quab yuam thiab post-tensioning quab yuam. Lub thickness ntawm ntxhib-dov ua tus nqi yog tsawg heev. Nws cov yam ntxwv dov yog txawv kiag li los ntawm dov ntawm txhuas daim hlau thiab strips. Nws muaj cov yam ntxwv ntawm aluminium foil dov. Nws qhov tshwj xeeb feem ntau suav nrog cov hauv qab no:
(1) Aluminium phaj thiab sawb dov. Ua kom cov txhuas sawb thinner feem ntau yog nyob ntawm lub zog dov, yog li txoj kev tswj tsis siv neeg ntawm cov phaj tuab yog ua raws li qhov sib txawv ntawm qhov sib txawv raws li txoj kev tswj lub ntsiab ntawm AGC. Txawm hais tias lub zog dov hloov, lub thickness tuaj yeem tau txais los ntawm kev kho qhov sib txawv ntawm qhov yob txhua lub sijhawm kom cov yob sib txawv ntawm ib qho nqi. Cov ntaub ntawv sib xws thiab cov khoom siv strip. Thaum aluminium ntawv ci dov mus rau nruab nrab-tiav dov, vim yog nyias nyias ntawm cov ntawv ci txhuas, nws yooj yim dua los ua kom lub zog dov thaum dov ua rau elastic deformation ntawm cov menyuam dua li tsim cov yas deformation ntawm cov khoom siv dov. Lub elastic flattening ntawm cov menyuam tsis tuaj yeem tsis quav ntsej. Yog lawm, elastic dov thiab flattening ntawm cov menyuam txiav txim siab tias nyob rau hauv cov ntawv txhuas dov, lub zog dov tsis tuaj yeem ua lub luag haujlwm tib yam li dov daim hlau. Aluminium foil dov feem ntau yog dov qhov sib txawv-dawb dov nyob rau hauv lub siab tsis tu ncua. Lub hom phiaj tseem ceeb ntawm kev kho cov tuab ntawm aluminium ntawv ci yog nyob ntawm kev kho qhov nro thiab dov ceev.
(2) Overlapping yob. Rau cov ntawv ci txhuas nrog lub thickness tsawg dua 0.012mm (qhov tuab yog cuam tshuam nrog txoj kab uas hla ntawm cov yob ua haujlwm), vim qhov elasticity ntawm yob, nws nyuaj heev rau yob nws nrog ib daim ntawv. Yog li ntawd, ob txoj kev dov yog siv, uas yog, ob nplooj ntawv ntawm txhuas ntawv ci yog dov. Cov ntawv ci txhuas ntxiv nrog cov roj lubricating hauv nruab nrab, thiab tom qab ntawd dov ua ke (tseem hu ua pawg dov). Laminated dov tuaj yeem tsis tsuas yog yob tawm cov ntawv txhuas uas tsis tuaj yeem tsim los ntawm ib daim ntawv dov, tab sis kuj txo cov kab nrib pleb thiab txhim kho kev ua haujlwm. Cov txheej txheem no tuaj yeem siv los ua cov khoom tsim ib leeg-ib sab txhuas ntawv ntawm 0.006mm txog 0.03mm.
(3) Cov nyhuv nrawm. Thaum lub sij hawm dov txheej txheem ntawm txhuas ntawv ci, qhov tshwm sim uas lub thickness ntawm cov ntawv ci yuav thinner nrog rau qhov nce ntawm dov degree yog hu ua cov nyhuv ceev. Qhov kev piav qhia ntawm cov nyhuv nrawm nrawm tseem xav tau kev tshawb fawb tob. Cov laj thawj rau cov nyhuv nrawm feem ntau ntseeg tias muaj peb yam hauv qab no:
1) Kev sib txhuam lub xeev ntawm kev ua haujlwm yob thiab cov khoom siv dov hloov. Raws li lub dov ceev nce, tus nqi ntawm cov roj lubricating tau nce, yog li ua rau lub xeev lubrication ntawm cov yob thiab cov khoom dov hloov. Kev sib txhuam coefficient txo qis, cov roj zaj duab xis yuav thicker, thiab lub thickness ntawm aluminium ntawv ci yuav thinner.
2) Kev hloov pauv hauv lub tshuab dov nws tus kheej. Nyob rau hauv ib lub rolling zeb siv cylindrical bearings, raws li lub dov ceev nce, lub caj dab yob yuav ntab nyob rau hauv cov kabmob, yog li ntawd ob tug interacting loaded yob yuav txav los ze zog rau ib leeg.
3) Cov txheej txheem softening thaum cov khoom yog deformed los ntawm dov. Lub dov ceev ntawm high-speed aluminium foil dov zeb yog siab heev. Raws li qhov dov ceev nce, qhov kub ntawm qhov dov deformation cheeb tsam nce. Raws li kev suav, cov hlau kub hauv cheeb tsam deformation tuaj yeem nce mus rau 200 degree, uas yog sib npaug rau qhov nruab nrab rov qab annealing, yog li ua rau cov txheej txheem softening tshwm sim ntawm cov ntaub ntawv dov.
