Dab tsi Sublimation ntawm Aluminium txhais tau tias
Dye sublimation yog kev hloov pauv, tsis yog txheej txheem luam ntawv ncaj qha rau hlau. Ib daim duab yog luam tawm nrog disperse dyes rau ntawm daim ntawv hloov, muab tso rau ntawm daim ntawv npaj, thiab tuav nyob rau hauv tshav kub thiab siab. Tshaj li ntawm 175 degrees Celsius cov dye hloov mus rau cov roj, cov ntawv txheej softens thiab qhib, thiab cov vapor mus rau hauv cov txheej txheem polymer, qhov uas nws nyob twj ywm kaw thaum lub vaj huam sib luag txias. Cov duab yog li ntawd nyob rau hauv lub txheej es tsis zaum saum nws.
Cov txheej txheem no piav qhia txog kev xav tau ntawm substrate. Bare mill-finished aluminium yuav tsis txais disperse dyes: qhov saum npoo tsis yog - ntxeem tau thiab chemically unreceptive, yog li daim duab luam tawm los yog tsis hloov txhua. Cov ntawv hlau luam tawm tau muab nrog cov txheej txheem polymer, feem ntau yog polyester-raws li lacquer, thov thiab kho ntawm lub zeb raws li kev tswj xyuas. Cov txheej, tsis yog alloy, yog dab tsi tau txais cov duab.
Yog vim li cas 3004 yog ib tug Common Substrate
3004 yog Al-Mn-Mg alloy ntawm 3xxx tsev neeg nrog 1.0 txog 1.5% manganese thiab txog 1.0 txog 1.5% magnesium. Nws ua ke lub zog nruab nrab nrog zoo heev flatness thiab formability, thiab nws tiv taus huab cua zoo dua li ib daim ntawv ntshiab 1xxx ntawm tib lub thickness. Rau lub vaj huam sib luag luam tawm qhov kev ua tau zoo yog qhov ruaj khov nyob rau hauv lub voj voog xovxwm, ib qho chaw uas tuav cov txheej adhesion los ntawm kev rov ua cua sov, thiab txaus nruj uas nyias cov ntsuas nyob twj ywm tiaj thaum mounted.
| Parameter | Ntau yam khoom siv |
|---|---|
| Alloy | 3004, qee zaus 3105 lossis 5052 rau cov haujlwm tshwj xeeb |
| Thickness | 0.3-3.0 hli |
| Daim ntawv loj | 1000 x 2000 mm thiab 1220 x 2440 mm, ntxiv rau txiav - mus rau - loj |
| Kub | H14, H24 lossis H32 nyob ntawm qhov yuav tsum tau muaj zog |
| Txheej | Sublimation -receptive polyester lacquer, ib los yog ob lub ntsej muag |

Hloov Parameters
Kev teeb tsa xovxwm tau hais los ntawm tus neeg xa khoom txheej txheej, thiab ua haujlwm sab nraud ua rau muaj qhov tsis xws luag ntau dua li lwm qhov sib txawv. Raws li qhov pib ua tau zoo, lub platen yog teem rau li 180 txog 200 degrees Celsius, siab yog nruab nrab thiab txawm, thiab lub sij hawm sib cuag los ntawm kwv yees li 30 mus rau 60 vib nas this nyob ntawm qhov ntsuas thiab txheej. Lub vaj huam sib luag tuab absorbs cua sov ntau dua thiab xav tau kev nyob ntev dua, thaum daim ntawv nyias nyias tuaj yeem dhau -hloov thiab poob qhov txhais yog tias tuav ntev dhau.
Thermal expansion yog tsim nyog npaj rau. Aluminium nthuav dav tshaj li ntawm 180℃lub voj voog, thiab cov vaj huam sib luag loj tuaj yeem hloov mus rau daim ntawv hloov chaw, uas ua rau lub ntsej muag lossis lub ntsej muag muag ntawm cov ntsiab lus zoo. Ua ntej- cua sov qhov khoob, kais qhov hloov chaw ruaj khov ntawm cov ces kaum, thiab tso cai rau lub vaj huam sib luag kom txias hauv qhov hnyav tag nrho txo qhov kev pheej hmoo. Tom qab hloov chaw, cov yeeb yaj kiab tiv thaiv lossis cov ntawv hloov pauv yuav tsum raug tshem tawm tsuas yog thaum lub vaj huam sib luag txias, txwv tsis pub cov txheej tuaj yeem raug cim thaum tseem mos.
Kev npaj thiab tuav
Deburr thiab huv si.Txiav cov npoo yuav tsum tau deburred thiab lub ntsej muag luam tawm tau so nrog isopropanol kom tshem tawm cov plua plav thiab cov ntiv tes ua ntej hloov mus.
Khaws cov txheej txheem kom zoo.Abrasive pads, alkaline cleaners thiab nplaum residues tag nrho cov kev puas tsuaj rau cov txheej txheem, thiab qhov kev puas tsuaj tshwm sim raws li ib tug patchy luam.
Tswj lub rooj cob qhia.Grit thiab swarf daig nruab nrab ntawm daim ntawv thiab txheej xovxwm los ntawm cov cim mus tas li.
Sib piv cov hloov.High-Tsev cov ntaub ntawv muab cov npoo ntawm cov ntawv zoo, thaum cov ntawv hnyav dua siab dua.
Xav txog qhov raug UV.Cov vaj huam sib luag npaj rau ntev - siv sab nraum zoov ib txwm tau txais kev tiv thaiv cov laminate los yog ib qho ntxiv UV- lub tsho tiv no ruaj khov, vim tias tsis muaj hnub ci uas tsis muaj hnub ci yuav ploj mus ntau cov xim pleev xim rau lub sijhawm.
Daim ntawv thov
Kos npe.Kev taw qhia thiab kev tshaj tawm cov vaj huam sib luag nrog tag nrho -cov duab xim uas yuav tsum tiv thaiv khawb hauv cov chaw pej xeem.
Diam duab thiab tso saib panels.Rigid qhia qhov chaw tiaj tus, qis- glare coated nto muab cov ntsiab lus zoo yam tsis muaj iav.

Kev Ntseeg Tsis Zoo
"Lub dye soaks rau hauv aluminium."Nws diffuses rau hauv lub polymer txheej; liab qab hlau yam tsis muaj cov txheej txheem txais tsis tuaj yeem luam tawm li no.
"Txhua daim ntawv txhuas tuaj yeem ua sublimated."Tsuas yog coated, sublimation- npaj ua haujlwm, thiab cov txheej txheem tau teev tseg nyias los ntawm cov hlau.
"Lub sublimated luam tawm tau txais huab cua tsis zoo."Cov duab zaum hauv cov txheej txheem organic, yog li ntev - siv sab nraum zoov ib txwm xav tau UV- cov txheej sab saum toj ruaj khov lossis laminate.
"Thicker daim ntawv ib txwm muab qhov txiaj ntsig zoo dua."Kev ntsuas cuam tshuam rau qhov tawv nqaij thiab qhov cua sov- lub sijhawm nce ntau dua li cov ntawv luam tawm zoo, thiab cov vaj huam sib luag tuab xav tau lub voj voog ntev dua.
"Kev kub siab dua txhais tau tias muaj xim zoo dua."Cov cua sov ntau dhau ua rau cov xim sib sib zog nqus, ua kom pom tseeb thiab tuaj yeem ua xim daj.
FAQ
Q: Puas yog daim ntawv 3004 tuaj yeem siv rau sublimation?
Tsis muaj; daim ntawv yuav tsum nqa ib sublimation -receptive polymer txheej, vim uncoated txhuas yuav tsis tuav disperse dye.
Q: Dab tsi xovxwm kub yog raug?
Feem ntau cov coated panels raug xa mus ntawm li 180 thiab 200 degrees Celsius rau 30 mus rau 60 vib nas this, ua raws li cov txheej txheem cov ntaub ntawv.
Q: Cov duab sublimated puas yuav ploj mus sab nraum zoov?
Lawv tuaj yeem ploj mus nyob rau lub hnub ncaj qha mus ntev, yog li kev ua haujlwm sab nrauv yuav tsum siv UV-cov yeeb yaj kiab tiv thaiv ruaj khov lossis txheej txheej ntxiv.
Q: Puas yog cov hlau tsis muaj teeb meem ntev npaum li daim ntawv coated?
Nws tseem ceeb rau kev nruj, flatness thiab corrosion kuj; 3004 tau xaiv dav vim nws sib npaug zog thiab huab cua tsis kam ntawm tus nqi qis.
Q: Yuav ua li cas coated ntawv yuav khaws cia?
Pav ca, qhuav, tiv thaiv los ntawm tshav ntuj ncaj qha, nrog interleaving los yog zaj duab xis nyob rau hauv qhov chaw thiab tsis muaj dab tsi stacked ntawm lub ntsej muag coated.
Q: Lub vaj huam sib luag luam puas tuaj yeem khoov tom qab hloov?
Yog, nrog kev saib xyuas; cov txheej yog nkig ntau dua li cov hlau, yog li khoov hla lub dov kev taw qhia nrog lub dav dav dav muab qhov txiaj ntsig zoo tshaj plaws.
