Dab tsi txhais Silver Loj Roll Aluminium Ntawv Nyiaj
Nyiaj loj yob aluminium ntawv ci yog lub teeb -gauge aluminium nkag rau hauv cov mills txuas ntxiv es tsis yog cov ntawv txiav. Cov nyiaj dawb-zoo li dawb tuaj ncaj qha los ntawm cov txheej txheem dov, uas tawm hauv cov xim hlau huv uas muaj kev cuam tshuam siab. Kev lag luam tus nqi ntawm cov ntawv yog nyob rau hauv yob: ib tug loj nruam ntev cia converting kab khiav tsis nquag splice nres, ua kom nro tas li los ntawm txheej txheej thiab laminating theem, thiab txo cov ntug trim pov tseg uas accumulates thaum nqaim coils koom.
Cov ntawv ci yog txhais los ntawm thickness es tsis yog lub npe: raws li EN 546-1 thiab ASTM B479 xyaum, txhuas ntawv ci yog strip hauv qab 0.2 hli, nrog cov qib ntim concentrated ntawm 0.006 hli thiab 0.15 hli. Cov ntawv yob loj rau cov khoom noj thiab cov neeg siv khoom ntim khoom feem ntau zaum hauv 0.007 hli txog 0.030 hli, qhov kev ua haujlwm tsis zoo twb tau siab thiab cov khoom siv tau yooj yim txaus rau qhwv, hau thiab lub hnab ntim khoom.
Kev xa tawm hom: zeb yob nrog 76 hli lossis 152 hli cores, sab nraud diameters txog li 1250 hli.
Dav ntau yam: feem ntau 300 mm txog 1700 mm, trimmed rau converter lub slitting txoj kev npaj.
Nto: ci zeb tiav, xaiv tau degreased rau wettability qib A rau luam ntawv thiab lacquering.
Barrier: opaque rau lub teeb thiab zoo impermeable rau dej vapor thiab gases ntawm thicknesses saum toj no li 0.009 hli.
8011 Alloy thiab Nruam Casting thiab Rolling Route
Silver loj yob aluminium ntawv ci yog tsim los ntawm 8011 alloy, ib qho Al-Fe-Si tsev neeg alloy tsim tshwj xeeb rau cov ntawv ci. Nws tsis yog cua sov- qib kho tau; lub zog los ntawm kev txo qis thiab los ntawm cov khoom zoo intermetallic uas pin cov qoob loo loj hlob thaum lub caij kawg. Lwm cov ntawv ci ua haujlwm rau cov kev xav tau uas nyob ib sab: 8079 muaj qhov yooj yim dua rau cov ntsuas nyias nyias, 1235 haum rau cov ntawv thov hluav taws xob thiab lamination, thiab 1100 lossis 3003 yog siv qhov twg yuav tsum muaj zog dua lossis sib sib zog nqus.
Ob txoj kev tsim khoom pub rau lub tshuab dov. Nruam casting thiab dov cam khwb cia hlau molten ntawm yob los tsim ib tug nyias slab uas yog tam sim ntawd txo, muab ib tug luv luv, lub zog -txoj kab npaum li cas raws li los ntawm - thickness qauv. Direct chill casting ua ib qho loj ingot uas yog homogenized, kub dov thiab ces txias dov, uas yields zoo nyob rau hauv huv si thiab yog nyiam rau cov tseem ceeb laminates. Nyob rau hauv ob qho tib si qhov kawg passes yog nqa tawm nyob rau hauv ib tug dov zeb nrog tsis siv neeg thickness thiab zoo tswj, ua raws li los ntawm slitting thiab annealing mus rau lub txiav temper.
| Qib | Cov thickness (mm) | Kub | Hom tensile zog (MPa) | Kev siv tseem ceeb |
|---|---|---|---|---|
| 8011 | 0.007-0.15 | H18 / H22 | 120-180 | Khoom noj khoom haus, luam yeeb thiab ntim tshuaj |
| 8079 | 0.006-0.05 | H18 / O | 80-160 | Nyias heev, siab - yooj yooj yim lidding |
| 1235 | 0.005-0.05 | H18 / O | 90-160 | Lamination, insulating ntsej muag |
| 3003 | 0.05-0.2 | H14 / H24 | 140-190 | Tsim cov thawv, cov khoom siv hluav taws xob |
Mechanical thiab Barrier Properties uas txiav txim siab daim ntawv thov
Peb ntsuas cov khoom txiav txim seb qhov twg muab yob tuaj yeem siv tau. Thickness kam rau ua tswj txheej qhov hnyav sib xws thiab kev foob kev ntseeg tau. Lub zog tensile thiab elongation txhais tau tias cov ntawv ci tseem muaj sia nyob ntawm kev luam ntawv, lacquering thiab lub hnab tsim yam tsis muaj cracking. Pinhole suav ib square meter teeb tsa qhov kev txwv tiag tiag, vim tias ntawm cov ntsuas hauv qab li 0.008 hli cov ntawv ci tsis tas mus tas li thiab qhov seem kis tau tus nqi nce nrog pinhole ntom.
Moisture, mildew thiab kev tiv thaiv poob siab ua raws li cov khoom no. Ib txheej ntawv ci tsis zoo thaiv cov dej vapor, oxygen thiab lub teeb yuav luag tag, yog li cov khoom ntim tau tiv thaiv los ntawm cov av noo-tsav caking, pwm loj hlob, oxidative rancidity thiab yees duab- degradation. Cov txheej hlau kuj tseem faib cov khoom cuam tshuam thiab muab cov neeg tuag-fold uas tuav lub crease, uas yog vim li cas cov ntaub qhwv ntawv kaw tsis muaj cov nplaum thiab vim li cas cov ntawv laminates tiv thaiv cov khoom tawg yooj yim thaum thauj.
Wettability yog cov cuab yeej converters ceeb toom ua ntej. Cov ntawv ci nqa cov roj nplaum uas seem uas yuav tsum tau muab tshem tawm ua ntej luam ntawv, lacquering lossis laminating, txwv tsis pub number case thiab nplaum yuav tsis thauj tog rau nkoj. Degreasing tau txheeb xyuas los ntawm kev ntsuas dej- ntub dej, uas cov yeeb yaj kiab dej txuas ntxiv yuav tsum nyob twj ywm tsis tawg rau ntawm qhov chaw, thiab cov khoom coil feem ntau tau lees paub rau qib A lossis B kom cov dej adhesion tuaj yeem rov ua dua tom qab khiav.
Daim ntawv thov hauv Khoom noj, luam yeeb thiab ntim khoom siv
Kev ntim zaub mov tseem yog qhov chaw loj tshaj plaws. Cov ntawv ci qhwv thiab lub hau cia siab rau txheej txheej thaiv kom tsis txhob ya raws thiab aroma hauv thiab oxygen tawm, thiab ntawm cov hlau saum npoo kom zam tau qhov kub thiab txias ntawm kev ua, los ntawm lub freezer cia rau qhov cub reheating, tsis deforming. Cov ntawv ci laminates nrog cov ntawv lossis cov yeeb yaj kiab polymer ntxiv rau kev tiv thaiv thaum ua kom cov txhuas txheej nyias txaus kom nyob twj ywm.
Kev ntim luam yeeb thiab luam yeeb siv cov ntawv ci los ua ib lub liner los yog cov ntawv ci -lined board, qhov twg cov khoom yuav tsum nyob twj ywm ci, tuav cov ntawv luam tawm kom meej thiab muaj sia nyob siab - ceev folding yam tsis tau tawg raws cov qhab nia kab. Cov neeg siv khoom thiab cov ntawv thov hauv tsev muaj xws li cov khoom siv mis nyuj, cov khoom siv tshuaj kho mob rov qab, cov tshuaj ntxuav tes thiab cov hnab ntim tshuaj pleev ib ce, rwb thaiv tsev ntsej muag thiab cov laminates zoo nkauj. Nyob rau hauv tag nrho cov no, kev xaiv ntawm 8011, 8079 thiab 3003 yog tsav los ntawm kev tsim hnyav thiab yuav tsum tau tuag-fold es tsis yog los ntawm ib leeg.
Yob Geometry, Kev Siv Khoom Siv thiab Kev Ua Haujlwm
Vim hais tias cov nyiaj loj yob aluminium ntawv ci yog yuav los ntawm qhov hnyav tab sis noj los ntawm qhov ntev, lub converter tus specification yuav tsum kho thickness thiab kam rau ua, dav thiab ntug mob, core txoj kab uas hla, sab nraud txoj kab uas hla thiab siab tshaj yob hnyav. Tight thickness kam rau ua kom cov txheej hnyav tuaj yeem kwv yees tau, thaum lub ntsej muag zoo ib yam tiv thaiv telescoping thiab web so thaum lub sij hawm unwinding. Rolls yuav tsum tau muab cia rau hauv tsev nyob rau hauv qhuav tej yam kev mob thiab tuav nrog ib tug mandrel es tsis yog los ntawm lub ntsej muag yob, vim hais tias txawm lub teeb txhua yam kev puas tsuaj rau lub txheej wraps tsim pinholes uas ncav cuag lub laminate tiav.
Rau kev tswj kom zoo, txhua lub kauj yog ib txwm txhawb nqa los ntawm daim ntawv pov thawj zeb npog alloy thiab temper, thickness profile, mechanical zog, wettability qib thiab pinhole tus nqi, kom cov kev soj ntsuam tuaj tuaj yeem sib phim rau cov kev hloov pauv hloov pauv tsis yog kev cia siab rau qhov pom kev pom ib leeg.
FAQ: Silver Loj Roll Aluminium Ntawv Nyiaj
Q: Dab tsi alloy yog siv rau nyiaj loj yob aluminium ntawv ci?
8011 yog qib feem ntau, nrog 8079 rau nyias nyias siab heev -cov ntaub ntawv yooj yim, 1235 rau lamination thiab 3003 qhov yuav tsum muaj zog ntau dua los yog tsim kom muaj qhov hnyav.
Q: Dab tsi thickness suav li txhuas ntawv ci?
Raws li EN 546-1 thiab ASTM B479 xyaum, ntawv ci yog txhuas sawb hauv qab 0.2 hli; Cov qib ntim ib txwm khiav ntawm 0.006 hli txog 0.150 hli.
Q: Vim li cas lub yob loj dua li cov ntawv txiav?
Ib qho txuas txuas ntxiv tso cai rau kev hloov pauv tsis tu ncua, lub vev xaib tsis tu ncua thiab tsis tshua muaj kev cuam tshuam, thiab nws txo cov pob qij txha uas tsim cov kab hauv laminates.
Q: Cov nyiaj ua tiav puas cuam tshuam rau kev ua haujlwm tsis zoo?
Tsis yog. Cov tsos mob tshwm sim los ntawm cov dov hlau nto, thaum qhov kev ua haujlwm tsis zoo yog teeb tsa los ntawm thickness thiab pinhole ntom, uas yog vim li cas kev ntsuas ntsuas qhov tseem ceeb tshaj xim.
Q: Vim li cas cov ntawv ci yuav tsum tau degreasing ua ntej luam ntawv lossis laminating?
Residual dov roj tiv thaiv tus number case thiab nplaum los ntawm anchoring; ib qho dej-kev ntsuas ntub dej rau qib A lossis B pom tseeb tias qhov chaw huv si ua ntej txheej txheej.
Q: Yuav ua li cas loj yob yuav tsum khaws thiab tuav?
Khaws cia rau hauv tsev thiab qhuav, nqa nrog lub mandrel los ntawm cov tub ntxhais, thiab tsis txhob sib cuag lub ntsej muag, vim hais tias cov ntaub qhwv sab nrauv qhia cov pinholes uas pheej mus rau hauv pob tiav.
