Xyoo ntawm Kev Ntsuas Tseeb Tshaj Tawm, Aluminium Foil Inkjet Printing, Qhov Tseem Ceeb yog Ob Qhov Teeb Meem

Xyoo ntawm kev ntsuas qhov tseeb qhia, aluminium foil inkjet luam ntawv, qhov tseem ceeb yog ob qho teeb meem

Nyob rau hauv cov txheej txheem luam ntawv ib txwm, yob aluminium ntawv ci cov ntaub ntawv feem ntau luam tawm flexographically, thiab ib daim ntawv ntawm aluminium foil ntawv luam tawm nrog offset printing. Piv txwv li, txhawm rau txhim kho qhov vividness ntawm cov xim thiab txhim kho qhov adhesion ntawm number case thiab aluminium foil cov ntaub ntawv, tshwj xeeb inks nrog polyphthalamine los yog vinyl chloride acetate copolymer resin raws li cov khoom tseem ceeb feem ntau siv hauv kev lag luam.

Nrog rau kev xav tau ntau ntxiv rau kev lag luam tus kheej thiab kev lag luam sai thiab hloov pauv ib puag ncig, qhov kev faib ua feem ntawm kev txiav txim luam ntawv rau cov khoom me me thiab ntau yam ntawm cov ntaub ntawv txhuas ntawv tseem nce ntxiv. Inkjet luam ntawv tau dhau los ua ib qho tseem ceeb rau kev hloov kho rau qhov kev thov no nrog nws cov txiaj ntsig tseem ceeb ntawm cov khoom me me thiab tus kheej, tab sis yuav ua li cas thiaj li ua tau zoo ntawm cov ntawv luam ntawv zoo hauv aluminium foil cov ntaub ntawv luam tawm thiab txhawb kev lag luam tau dhau los ua qhov teeb meem ceev los daws kev lag luam.

Cov kev xav tau thiab cov ntsiab lus mob ntawm inkjet luam ntawv nyob rau hauv daim ntawv thov ntawm txhuas ntawv ci cov ntaub ntawv

Aluminium ntawv ci yog qhov sib txawv ntawm cov ntaub ntawv luam tawm ib txwm muaj xws li ntawv, PVC, PET, BOPP, thiab lwm yam, thiab feem ntau ntsib ob hom teeb meem hauv qab no hauv cov txheej txheem luam ntawv inkjet yam tsis muaj inks tshwj xeeb:

Ua ntej, lub zog tensile ntawm aluminium ntawv yog loj, yuav luag tsis yog -stretchable, thiab lub zog tsim kua muag yog me me thiab nto yog du.

Thib ob, lub zog saum npoo ntawm cov khoom siv aluminium foil yog qhov tsawg, ua rau tsis zoo adhesion tom qab cov number case txheej ntawm nws qhov chaw qhuav, thiab nws yooj yim los ua tus number case poob.

Raws li cov teeb meem saum toj no, cov cuab yeej siv inkjet luam ntawv tam sim no ntawm kev ua lag luam tsis tshua sim ua cov ntawv txhuas ntawv luam ntawv. Tus kws sau ntawv tau koom nrog kev tshawb fawb ntawm cov kev daws teeb meem digital inkjet luam ntawv tau ntau xyoo, thiab tam sim no qhia txog cov kev paub zoo nrog cov phooj ywg los muab kev siv rau kev lag luam.

Aluminium ntawv ci inkjet luam ntawv qhov mob point tov

01

daws cov teeb meem ntawm daim ntawv slippage, deflection thiab khawb ntawm lub nozzle

Nyob rau hauv saib ntawm cov yam ntxwv ntawm du nto thiab tsis tshua muaj stretchability ntawm aluminium ntawv ci, peb yuav tsum tau teem lub nro kom tsim nyog loj nyob rau hauv ntau lawm nyob rau hauv lub premise ntawm tsis wrinkling los yog tawg, thiaj li tsis txhob cov khoom slipping ntawm cov ntawv qhia cov menyuam thiab tiv thaiv lub deflection phenomenon tshwm sim los ntawm unstable khoom kis tau tus mob. Nyob rau tib lub sijhawm, tsim nyog nce qhov nro kuj tuaj yeem txhim kho qhov teeb meem ntawm cov khoom siv warping rau qee yam thiab txo qhov tshwm sim ntawm lub nozzle raug khawb.

Nws yuav tsum raug sau tseg tias tsis muaj kev sib koom ua ke tus qauv siv rau kev teeb tsa nro - muaj qhov sib txawv ntawm servo tsav system thiab kev ua kom zoo ntawm cov khoom siv sib txawv siv los ntawm cov tuam ntxhab sib txawv, thiab nws raug pom zoo kom nce qhov nro ntau npaum li qhov ua tau hauv qhov tseeb ntawm kev ua kom ntseeg tau tias cov khoom tsis plam.

02

daws qhov teeb meem ntawm tus cwj pwm tsis zoo ntawm tus number case adhesion thiab ink poob

Txhawm rau daws qhov teeb meem ntawm tus cwj mem adhesion, nws yog thawj zaug uas yuav tsum tau ua kom paub meej qhov tseem ceeb ntawm qhov nro: qhov nro ntawm inkjet luam ntawv number case nyob rau hauv kev ua lag luam feem ntau yog li 38dyn / cm, thiab tsuas yog thaum lub npoo ntawm cov khoom luam ntawv tuaj yeem loj dua qhov nro ntawm tus number case tuaj yeem ua tiav cov nyhuv ntub dej kom tsis txhob poob number case. Txawm li cas los xij, qhov nro ntawm cov ntawv txhuas tsis kho yog qhov nyuaj kom ncav cuag ntau dua 38 dyn / cm; Tsis tas li ntawd, qhov saum npoo ntawm aluminium ntawv ci tsis muaj qhov porosity, thiab tus number case tsis tuaj yeem nkag mus rau hauv nws sab hauv los ua "anchoring effect", txawm tias tus number case raug xa mus thiab qhuav, nws tseem ua rau tus number case poob.

Hauv kev teb rau qhov teeb meem no, peb feem ntau siv kev kho mob corona lossis ua ntej - txheej txheem txheej los daws nws, thiab cov kev coj ua tshwj xeeb yog raws li hauv qab no.

(1) txheej txheem kho Corona

Lub hauv paus ntsiab lus ntawm kev kho mob corona yog siv lub siab - zaus voltage ntawm cov insulating electrode thiab lub hauv paus dielectric nruas, tawg thiab plasmizing cua ntawm ob tug ncej. Thaum cov plasma particles cuam tshuam nrog lub ntsej muag ntawm aluminium ntawv ci, lawv tuaj yeem qhib cov tshuaj tiv thaiv ntawm cov khoom siv, tsim cov dawb radicals, ua kom lub ntsej muag ua kom nrawm, thiab tom qab ntawd txhim kho lub zog saum npoo thiab qhov ntub dej ntawm cov ntawv ci txhuas, thiab thaum kawg txhim kho lub zog adhesion ntawm tus number case thiab aluminium foil nto.

Hauv kev tsim khoom tiag tiag, cov cuab yeej corona tuaj yeem ntsia tau rau ntawm cov khoom siv inkjet luam ntawv kom ua tiav kev kho mob corona online, tab sis lub zog corona yuav tsum tau txiav txim siab los ntawm kev sim. Noj cov khoom siv corona nrog lub zog ntawm 2kW ua piv txwv, cov qauv ntsuas ntsuas yog 30% ~ 50% ntawm lub zog faib; Yog tias tseem muaj tus lej sau thiab tus number case poob hauv kev luam ntawv tom qab siv li 50% ntawm lub zog rau kev kho mob corona, nws txhais tau tias cov ntaub ntawv txhuas tsis tuaj yeem txhim kho kev luam ntawv los ntawm kev kho mob corona, thiab tsis tas yuav mus txuas ntxiv mus sim lwm qhov sib piv ntawm lub zog, thiab koj tuaj yeem tig mus rau qhov ua kom zoo ntawm pre- txheej txheem txheej.

Tom qab kev sim, nws tau pom tias kev kho mob corona tuaj yeem txhim kho lub zog saum npoo ntawm txhuas ntawv ci ua cov khoom siv hluav taws xob, tab sis tseem muaj chaw rau kev ua kom zoo ntawm cov nyhuv (cov nyhuv sib piv yog pom hauv daim duab 1).

(2) Ua ntej- txheej txheem txheej

Tom qab lub sijhawm ntev - kev ntsuas lub cev, tus sau tau pom tias cov txheej txheem ua ntej - txheej txheej tuaj yeem txhim kho cov nyhuv adhesion ntawm tus number case, tab sis nws yog ib qho tsim nyog yuav tsum tau tsom mus rau peb qhov teeb meem tseem ceeb, xws li, xaiv tus naj npawb ntawm anilox rollers (tswj tus nqi ntawm pre- txheej), pre- txheej txheem txheej txheem (online/offline 4} txheej txheem), tag nrho cov no yuav tsum tau txiav txim siab los ntawm kev ntsuam xyuas qhov tseeb.

Kev xaiv ntawm anilox rollers tuaj yeem xa mus rau cov qauv hauv qab no: anilox rollers nrog 600 ~ 1000 kab thiab number case load txog 3.95bcm³ feem ntau siv rau ua ntej- txheej cov khoom siv pa; Rau cov ntaub ntawv tshwj xeeb xws li txhuas ntawv ci, nws raug nquahu kom xaiv anilox rollers nrog txog 800 kab tom qab kuaj, thiab cov txheej thickness tsis tas yuav tsum yog tuab heev kom tau raws li cov kev xav tau ntawm number case adhesion.

Txoj kev ua ntej- txheej txheej yog muab faib ua offline ua ntej- txheej thiab online ua ntej- txheej: offline pre- txheej yog hais txog ua ntej- txheej txheej aluminium ntawv rau ntawm cov khoom siv flexo luam ntawv ua ntej, thiab tom qab ntawd cov ntawv ua ntej- coated aluminium ntawv yog muab tso rau hauv lub tshuab rau inkjet luam ntawv; Online pre- txheej yog nruab nrog lub tshuab luam ntawv flexo ntawm lub tshuab luam ntawv inkjet, uas paub txog kev ua tiav online ntawm ua ntej- txheej thiab inkjet luam ntawv, thiab muaj kev hloov pauv ntau dua. Tus sau kuj pom zoo kom siv online ua ntej - txheej rau aluminium foil inkjet luam ntawv.

Kev xaiv cov dej ua ntej- txheej txheej yuav tsum coj mus rau hauv tus account ob qhov ntev: ua ntej, kev hloov pauv ntawm cov txheej txheem ua ntej- txheej txheej thiab cov khoom siv aluminium ntawv ci, raws li cov khoom siv aluminium ntawv ci, cov khoom siv flexo luam ntawv ua ntej - txheej txheej tuaj yeem xaiv tau; Qhov thib ob yog qhov kev hloov pauv ntawm cov tshuaj ua ntej - txheej txheej thiab cov cwj mem digital, uas yuav tsum tau kuaj thiab txheeb xyuas los ntawm kev ua kom muaj kev hloov pauv ntawm cov txheej txheem ua ntej - txheej txheej thiab txhuas ntawv ci, ua ke nrog cov cwj mem digital hom siv.

Lub thickness ntawm pre- txheej muaj qhov cuam tshuam loj rau cov nyhuv adhesion ntawm tus number case, raws li pom nyob rau hauv daim duab sab laug ntawm daim duab 2, cov nyhuv ntawm pre- txheej yog tuab, thiab tus number case tseem poob tawm thaum lub sij hawm khawb. Daim duab ntawm sab xis qhia tau hais tias cov nyhuv thaum ua ntej - txheej tuab yog tsim nyog, txawm tias muaj cov khawb pom tseeb, tsis muaj tus lej poob.
