Puas yog cov teeb meem no nquag tshwm sim thaum siv UV number case? Nov yog qhov kev daws teeb meem - xyuas nws!

UV number case yog dav siv nyob rau hauv daim ntawv lo luam ntawv vim nws cov xim tiag tiag, siab gloss, dej tsis kam, hnyav tsis kam, abrasion tsis kam, thiab ceev curing ceev. Nws yog dav siv nyob rau hauv daim ntawv lo luam ntawv, xws li letterpress, flexograph, offset printing, thiab digital printing. Hauv tsab xov xwm no, kuv yuav qhia luv luv yuav ua li cas siv UV number case zoo, nrog rau qee qhov teeb meem tshwm sim thaum nws siv, vam tias yuav ua rau koj nyiam.

Yam yuavtsum tau kawm uantej kom siv tau zoo ntawm UV number case

Txhawm rau kom muaj txiaj ntsig zoo ntawm UV number case, lub wavelength ntawm UV teeb feem ntau yuav tsum nyob nruab nrab ntawm 180 ~ 420nm, thiab lub zog yuav tsum tsis pub tsawg dua 80W / cm². Lub neej kev pab cuam ntawm UV teeb yog 1000 teev; Yog tias lawv dhau lub sijhawm kev pabcuam, kev kho kom zoo tsis tuaj yeem lav tau. Yog tias muaj kev tso cai, UV teeb tuaj yeem tig tau 90 degree, uas yuav pab xyuas kom meej tias tag nrho cov kab hluav taws xob UV ua haujlwm tau zoo mus rau txheej txheej luam ntawv, txhim kho kev ua haujlwm zoo. Tsis tas li ntawd, thaum siv, xyuas kom meej tias cov khoom cua txias thiab qhov cua yog qhov zoo los lav tias qhov kub thiab txias ua haujlwm ntawm UV kho cov cuab yeej ib txwm nyob hauv qhov kev tso cai.

Raws li paub zoo, viscosity ntawm UV number case yog ze ze rau qhov kub thiab txias. Tsawg kub txhais tau tias qis viscosity, siab kub txhais tau tias siab viscosity. Yog li ntawd, ua ntej siv, tus number case yuav tsum raug coj mus rau lub rhiav thiab sab laug rau lub sij hawm ntawm lub sij hawm kom tswj tau qhov kub thiab txias. Tsis tas li ntawd, thaum luam ntawv, UV number case curing nyhuv yuav tsum tau saib xyuas. Tom qab cov ntawv luam tawm txias rau chav tsev kub, 3M-600 daim kab xev tuaj yeem siv los ntsuas qhov adhesion lub zog ntawm tus number case txheej. Feem ntau, tom qab 24 teev ntawm kev cia, tus number case adhesion yog qhov zoo tshaj plaws.

Cov no yog qhov yuav tsum tau ua ntej rau kev siv UV number case zoo, tab sis hauv kev luam ntawv tiag tiag, qee qhov teeb meem yuav tshwm sim, xws li ink ink curing tsis tiav thiab adhesion tsis zoo. Hauv qab no yog ib qho kev soj ntsuam ntawm cov laj thawj thiab kev daws teeb meem ntawm ntau yam teeb meem uas tau ntsib hauv cov txheej txheem luam ntawv.

Cov teeb meem uas siv UV Ink Analysis

01

Ink curing tsis tiav

Teeb meem piav qhia

Ink muaj nyob rau ntawm daim ntawv qhia cov menyuam ntawm cov tshuab luam ntawv thiab hloov mus rau substrate; Tom qab dov, lub nraub qaum ntawm cov khoom luam tawm tau qias neeg.

Kev daws

Yuav kom daws tau qhov teeb meem ntawm UV ink curing tsis tiav, koj yuav tsum nrhiav qhov laj thawj los ntawm peb yam: cov cuab yeej kho, luam ntawv, thiab tus number case nws tus kheej, thiab tom qab ntawd daws qhov teeb meem raws li.

Ua ntej, xyuas seb av puas thaiv lub teeb UV ntawm qhov chaw ntawm UV teeb thiab lub teeb pom kev zoo. Yog tias ua tau, ntxuav nws thiab txhim kho tus cwj pwm tsis tu ncua ntawm kev tu lub teeb UV, lub teeb ci, thiab lub teeb pom kev zoo nrog cov dej cawv tsis muaj dej. Tib lub sijhawm, tshawb xyuas lub sijhawm siv ntawm UV teeb. Yog tias nws tau dhau nws txoj sia, nws yuav tsum tau hloov kom ntseeg tau tias lub teeb muaj lub zog txaus, lossis siv ntau lub teeb ntawm UV kom nce UV hluav taws xob.

Kev luam ntawv nrawm dhau ua rau UV number case tau txais UV hluav taws xob tsis txaus, ua rau lub sijhawm kho luv luv, ua rau kev kho tsis tiav ntawm UV number case. Nyob rau hauv cov ntaub ntawv no, txo cov printing ceev yuav daws tau. Yog tias cov txheej number case tuab dhau lawm, tsuas yog qhov chaw ntawm UV number case kho thaum sab hauv tsis tiav. Nyob rau hauv cov ntaub ntawv no, lub anilox cov menyuam yuav tsum tau hloov, thiab tus number case yuav tsum raug txo kom tsim nyog kom txo lub thickness.

Cov saum toj no yog cov laj thawj sab nraud rau kev kho tsis tiav ntawm UV number case, thaum qhov ua rau sab hauv yog tias UV number case qhov nqus spectrum sib phim cov emission spectrum ntawm UV teeb nyob rau hauv ib qho kev nqaim. Hauv qhov no, tus nqi tsim nyog ntawm photosensitizer tuaj yeem muab ntxiv rau tus lej ntawm qhov sib piv ntawm 1% ~ 3%. Los ntawm kev nthuav dav qhov nqus spectrum ntawm tus number case, kev kho kom zoo tuaj yeem txhim kho, yog li txhim kho cov nyhuv curing.

Poor number case txheej adhesion

Teeb meem piav qhia

Thaum kuaj tus number case txheej adhesion nrog 3M-600 daim kab xev, tus number case yuav detach los ntawm substrate nto, los yog tom qab number case yuav detach los ntawm pre-printed number case txheej.

Kev daws

Kev xaiv tsis raug ntawm cov substrate lossis qhov nro qis yog qhov ua rau muaj qhov tsis zoo ntawm tus number case adhesion. Yog hais tias lub substrate tsis phim tus number case, nws yuav tsum tau hloov; Rau cov ntaub ntawv yas zaj duab xis, kev kho mob corona tuaj yeem ua rau muaj qhov nro saum npoo los yog ntxiv cov txheej txheem los txhim kho adhesion. Nyob rau hauv luv luv, xyuas kom meej qhov nto nro mus txog saum 38 dynes.

Qee qhov xwm txheej, tus cwj pwm tsis zoo kuj tseem cuam tshuam nrog kev tsim tus number case. Yog hais tias qhov teeb meem no tshwm sim nyob rau hauv txawv batch ntawm tus number case piv thaum lub sij hawm sim, ib tug pre- luam ntawv txheej yuav siv tau ua ntej luam tus number case.

Thaum siv stamping ua ntej luam ntawv, yog tias tus number case adheres tsis zoo rau saum npoo ntawm stamping ntawv ci thiab yooj yim tev tawm, kua roj vanish tuaj yeem siv rau kev tiv thaiv. Kev ua tsis zoo ntawm cov txheej number case feem ntau yog tshwm sim los ntawm ntau tshaj - kho ntawm pre- xim number case, yog li lub zog kho ntawm pre- xim UV teeb tuaj yeem raug txo kom tsim nyog. Ink curing tsis tiav kuj yog ib qho ntawm cov laj thawj rau cov cwj pwm tsis zoo. Nrhiav qhov laj thawj thiab ntsuas qhov tsim nyog.

03

Random kab -zoo li cov xim xim tshwm

Teeb meem piav qhia

Nyob rau tib nplooj ntawv thiab tib xim, tsis xwm yeem linear dots tshwm, zoo li tua hnub qub.

Kev daws

Ntau yam teeb meem nrog tus squeegee yog feem ntau ua rau qhov tshwm sim no. Yog hais tias lub squeegee puas lawm, nws yuav tsum tau hloov; Yog hais tias lub squeegee yog nyias los yog cov khoom yog mos, koj muaj peev xwm ntxiv ib tug rov qab hniav los yog hloov mus rau ib tug scraper hniav nrog ib tug tuab ntawm 0.15mm ~ 0.3mm. Tsis tas li ntawd, kev sib cuag cov ces kaum tsis raug kuj tuaj yeem ua rau qhov teeb meem no. Nws raug nquahu kom teem lub kaum sab xis rau 20℃~ 35 degree. Siab squeegee siab kuj yog ib qho ntawm cov laj thawj, yog li nws yog qhov zoo tshaj plaws los siv lub lightest squeegee siab.

Txhawm rau daws qhov teeb meem no, koj tuaj yeem pib nrog anilox rollers. Thaum ua kom tus number case hloov ntim, hloov lawv nrog cov yob nrog cov kab ntau dua tuaj yeem muab kev txhim kho zoo. Tsis tas li ntawd, ntau tus cwj mem viscosity tuaj yeem ua rau tsis zoo rau cov cwj mem hloov thiab teeb meem. Ntxiv cov thinner tuaj yeem siv los txo tus lej viscosity. Txhawm rau khaws cov xim concentration, cua sov tuaj yeem siv tau, tshwj xeeb tshaj yog nyob rau sab qaum teb thaum lub caij ntuj no.

04

Cov khoom luam tawm tsis yog hnub ci -resistant

Teeb meem piav qhia

Cov ntawv sau ploj tom qab raug tshav ntuj rau lub sijhawm.

Kev daws

Cov inks sib txawv muaj qib sib txawv ntawm lub hnub tiv thaiv. Yuav kom ua tiav lub hnub zoo tshaj plaws, koj yuav tsum xaiv cov inks nrog cov qib siab dua. Thaum sib xyaw cov xim xim xim, yuav tsum tau them nyiaj mloog rau lub hnub - qib ntawm cov xim xim xim nyob ntawm lub hnub - resistant qib ntawm txhua tus thawj xim number case siv. Yog tias lub hnub xaiv tau- tus number case resistant twb txaus lawm tab sis tseem tsis tuaj yeem ua tau raws li lub hnub xav tau - lub sij hawm tiv taus, cov number case txheej thickness tuaj yeem tsim nyog.
