Cov txheej txheem ntawm ntim cov ntawv txheej txheem aluminium yog: aluminium ntawv pov thawj unwinding → gravure printing → drying → coating tiv thaiv txheej txheem → drying → txheej txheej txheej nplaum → kom qhuav tshuab aluminium winding. Yuav kom ua tau raws li cov kev cai saum toj no hauv PTP txhim kho cov ntawv xov xwm thiab cov txheej txheem txheej txheem, nws tseem ceeb heev kom paub txog cov khoom ntawm cov ntaub ntawv raw, thiab them nyiaj rau cov teeb meem nram qab no thaum lub sijhawm ua haujlwm:
1. Qhib cov yam ntxwv ntawm aluminium ntawv ci thiab luam ntawv number case
Cov khoom siv rau kev zus ntawm PTP cov ntawv txhim khu yog cov ntaub ntawv muaj kuab aluminium. Feem ntau, lub thickness yog 0.02 hli, lub zog tensile 98kPa, tawg qhov yog 90kPa, nplaim huv, tiaj, tsis wrinkles, tsis muaj indentation puas, tsis muaj flakes, tsis muaj deg. Lub qhov nro tsis yog tsawg tshaj 32. Qhov yuav tsum tau ua rau lub pinhole ntawm cov ntaub ntawv kho paj yeeb uas yog tias cov pinhole muaj ib txoj kab uas muaj 0.1-0.3 hli tsis tshaj 1 / m 2. Vim cov pinhole nyob rau hauv cov ntawv txhuas txhuas hniav yog qhov tob tob, qhov tshuaj yog degraded los yog deteriorated los ntawm intrusion ntawm oxygen, dej vapor thiab lub teeb, yog li qhov yuav tsum tau rau cov pinhole yog nruj heev; Ntxiv rau, yog tias cov tuab tuab ntawm cov ntawv pov thawj aluminium ntau tshaj qhov yuav tsum tau sib txawv (Thaum nws yog 10%), nws yuav cuam tshuam qhov txheej txheem ntawm cov txheej txheej thiab cov txheej txheem tiv thaiv, thiab nws yog ib qho tsim nyog yuav tsum nyiam cov neeg ua haujlwm.
Cov ntawv luam tawm hauv cov ntawv txhuas txhuas yog tam sim no muab faib ua ob pawg: ib qho yog ib tug cwj mem polyamide. No hom ntawm tus cwj pwm muaj zoo adhesion, dispersibility, gloss, abrasion kuj, hnyav tso, softness thiab yog siv rau cov luam ntawm yas zaj duab xis. Thaum siv cov ntawv luam ntawv aluminium ntawv ci, cov khoom siv zoo ntawm cov zauv muaj peev xwm yuav qhia tau, thiab cov cua kub kuj tuaj yeem ua tau raws li cov ntawv ntawm cov ntawv xov xwm ntawm cov ntawv xov xwm. Lwm hom yog tus cwj mem tshwj xeeb rau aluminium foil muaj cov chloride yas acetate copolymerized hluavtaws resin / acrylic cob raws li lub ntsiab tivthaiv. Nws cov taw tes tuav yog ci xim, siab concentration, muaj zog adhesion rau aluminium ntawv ci, zoo transparency, tab sis vim nyob rau hauv lub gravure printing, qhov hnyav volatility loj, thiab nws yog yooj yim ua tus number case kom qhuav thiab deposit hauv lub inking qhov ntawm lub gravure dov thaum lub PTP tshuaj txhuas cov ntawv sau, thiab qhov tshwm sim tshwm sim tshwm sim. Yog li, nws tsim nyog yuav tsum ua kom tsim nyog rau kev tso dej thiab muab khov ntawm tus cwj pwm los ntawm kev nplawm los yog nce lub ntsuas kub (dej da dej) ntawm khov dua uas khov. Yog hais tias lub sij hawm cia ntawm tus number case ntev, tus number case yuav tso, uas ua rau ntau resin nyob rau hauv txheej sab sauv ntawm tus cwj mem, ntau xim hauv cov txheej sab nraud, xim sib dua hauv txheej txheej, thiab xim ib tsos tsaus nti hauv sab txheej. Nws kuj yuav tsum tau ua thiab siv tau.
2. Tus nqi hnyav ntxiv rau tus cwj pwm yuav tsum tsim nyog
Thaum ib tus cwj pwm viscosity siab yuav tsum tau diluted nrog ntau tus nqi ntawm kev ua si, nws yuav tsum tau sib tov thaum ntxiv ib qho kev sim kom sib npaug muab faib rau txhua hnub ntawm tus cwj mem. Lub ntsuas yog ntsuas txog 20-30 li. Sab hauv tsev sov thiab cov av noo muaj cov nyhuv ntawm cov ink mem tes. Nws yog qhov zoo tshaj plaws los siv tus ntim roj hmab ntim quav los txiav txim seb qhov hnyav npaum li cas, thiab txiav txim siab txog tus lej mem tes ntawm cov kev ua haujlwm raws li cov kev hloov hauv qhov kub thiab txias. Thaum cov roj hmab txhuas khoom tau sau los ntawm gravure printing, tus number case concentration tsawg dhau, uas yuav ua rau cov ntawv luam tawm qauv tsis kaj lug thiab cov tshuaj muab los ntawm lub vas sab; Yog hais tias tus number case concentration ntau dhau, cov kab nrib pleb yuav tshwm sim ntawm tus qauv, uas tsis yog cias quav, tab sis kuj yog yooj yim ua rau luam tawm tsis ncaj thiab tsis zoo nkauj. Ntxiv rau qhov no, tus cwj pwm zoo yog xaiv raws li kev ceev ntawm cov ntawv pov thawj cov ntawv xov xwm thiab qhov tob ntawm tus cwj mem xaj cim ntawm lub pob zeb gravure yob.
3. Cov nplaum yuav tsum ua kom tau raws li cov cai
Lub nplaum ntawm PTP txhuas cov ntawv nyiaj yog coated rau sab hauv sab ntawm cov ntawv ci txhuas, thiab nws cov kev ua haujlwm yog ua rau cov ntawv ci txhuas thiab cov ntaub ntawv ntawm cov tawv nqaij PVC kom ruaj nrees thaum tshav kub kub, yog li ntawd cov tshuaj nyob rau hauv cov yas tawv daim ntawv cov hlwv yog sib cais los ntawm sab nraud kom ua tau lub sealing ntawm cov tshuaj. lub hom phiaj. Nyob rau hauv txoj kev kub-sealing cov tshuaj, cov txheej nplaum yog qhib los ntawm cov tshav kub lub siab, thiaj li yuav khov kho ua ke rau PVC yas tawv ntawv, uas yuav tsum tau cov txheej nplaum thiab cov PVC resin kom muaj cua kub zoo thiab lub substrate . Compatibility.
4. Kub thiab lub sij hawm qhuav yuav tsum tau siv thaum lub sij hawm luam ntawv thiab txheej
Cov ntawv luam tawm thiab cov txheej nplaum thiab cov txheej txheem tiv thaiv yuav tsum tau qhuav thaum lub txheej txheem txheej txheem. Kev ziab ntawm cov nplais txheej ntawm cov txheej txheem aluminium yuav tsum muaj txheej txheem, vim li ntawd nws yuav tsum nyob hauv lub qhov ziab ntawm cov cuab yeej siv rau ib lub sijhawm, uas nyob ntawm cov txheej tshuab winding. Qhov ceev thiab qhov kub tau xaiv nyob hauv qhov ziab qhov ziab yuav tsum sib txuas rau txhua lwm yam. Vim yog qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom ci txhuas, cov khoom thiab lub zog sib txawv, thiab thermal expansion, shrinkage, thiab elongation ntawm cov khoom thaum lub sijhawm ua haujlwm kuj sib txawv, yog li qhov chaw nyob yuav tsum tsis txhob ntev dhau ntawm lub siab kub, lwm yam ntawv txhuas txhuas Nws yog ib qho yooj yim rau wrinkles thiab deg. Feem ntau, qhov kub ntawm qhov ziab qhov quav yog tswj ntawm 170-210 ° C.
5. Tsom xam ntawm kev luam cov txheej ceev, txheej nro thiab txheej thickness thiab tsevneeg zoo
Qhov txheej thickness ntawm cov nplaum txheej thaum lub sij hawm luam thiab txheej txheej tau zoo heev ntawm lub zog ntawm adhesion lub hnab yas PVC, thiab cov nplaum dhau lawm yog nyias. Thaum cov ntawv tawv PVC raug kub hnyiab, lub adhesion ceev nrooj txo vim yog tsis muaj cov khoom; Qhov txheej yog tuab heev, uas tsis tsuas yog nce tus nqi, tab sis kuj xav kom ntev lub sij hawm qhuav, yog li nws yuav tsum tau tswj raws li qhov tsim nyog tuab. Lub txheej thickness ntawm cov nplaum kab yog cuam tshuam los ntawm cov concentration ntawm lub nplaum, lub nro qhov nrawm, qhov txheej ceev, thiab cov xov tooj ntawm anilox yob. Nyob rau hauv cov ntaub ntawv ntawm cov duab, qhov tob, tus lej ntawm ib nti, thiab txoj kab siab ntawm ob lub yob, qhov ntau dua qhov txuas ntawm phau ntawv, qhov me me qhov nro nrawm, thiab ceev ceev txheej, lub thicker lub txheej. . Yog li ntawd, lub thickness ntawm cov nplaum kab feem ntau yog kho los ntawm cov concentration ntawm lub binder thiab qhov nro ntawm lub coater. Txawv ntawm hom aluminium ntawv nyias muaj nyias txoj hauv cov thickness ntawm cov txheej nplaum. Feem ntau, lub thickness ntawm txheej yuav tsum tau tswj ntawm 3.5-7.0 hli. Nyob rau hauv cov ntawv txhim khu printing thiab txheej, qhov ceev, kub thiab nro muaj feem xyuam rau ib leeg thiab muaj kev txwv khi. Kev koom tes zoo ntawm lawv yog ncaj qha ntsig txog kev luam ntawv zoo ntawm cov ntawv nyiaj txhuas.
