4 yam uas cuam tshuam rau tom qab luam ntawv zaj duab xis teebmeem hauv phau ntawv luam tawm
Cov yeeb yaj kiab coating tsis yog tsuas yog ntsig txog txheej txheem ntawm cov txheej txheem cov ntaub ntawv raw thiab cov kab ua luam yeeb zauv, tab sis qhov tseem ceeb dua, nws tseem muaj feem xyuam rau cov xwm txheej ntawm cov ink tab txheej ntawm cov ntawv luam tawm. Cov xwm txheej ntawm tus number case hauv cov ntawv luam tawm yog qhov kev txiav txim siab los ntawm cov ntawv ntawm daim ntawv, tus lej cim, lub thickness ntawm tus number case, cov cheeb tsam ntawm daim duab, thiab qhov sib dhos ntawm cov ntawv luam tawm. Cov cwj pwm no muaj feem xyuam rau txoj kev sib koom tes ntawm kev sib txuas ntawm lub cuab yeej ua ke, lub hwj chim ntawm lub cev chemistry, thiab cov zoo li, thiab yog li ua rau muaj kev hloov ntawm cov nplaum ntawm cov ntawv luam tawm.
1. Luam tawm ntawm cov quav
Xim txheej nrog cov khoom uas muaj tuab tuab heev mas feem ntau nyuaj rau cov nyiaj nrog cov yas yeeb yaj kiab thiab yuav sai sai no delaminate thiab ua npuas dej. Qhov no yog vim tias cov quav ntawm cov lej uas hloov cov xim ntawm cov ntawv thiab ntxig cov kab npab ntawm daim ntawv fibers, uas ua rau kom nkag mus rau qhov hluav taws xob thiab qhov hluav taws xob. Qhov nkag mus ntawm lub nplaum rau ib qho twg yog qhov zoo rau lub adhesion ntawm txheej.
Tsis tas li ntawd, thaj tsam ntawm tus cwj mem thiab tus number case txheej ntawm daim ntawv yog txawv, thiab cov nplaum ua haujlwm zoo sib xws. Kev sim ua pom tau hais tias nrog kev nce ntawm cov inkness txheej los yog qhov nce ntawm thaj tsam ntawm daim duab, qhov nqi nro nqi yog ho txo. Vim li no, ob qho tib si monochromatic printing thiab multicolor printing yog nrhiav kev tswj tus cim number case rau ib qho me me.
Lub thickness ntawm lub printing number case txheej tseem ncaj qha ntsig txog txoj kev luam ntawv. Txoj kev luam ntawv yog txawv, thiab tus lej hauv plhaub thickness kuj txawv. Piv txwv, thickness ntawm tus number case ntawm txheej lithographic yog kwv yees li 1 mus rau 2 μm, kwv yees li 2 mus rau 5 μm rau embossing, thiab 10 μm rau gravure printing. Ntawm qhov kev pom ntawm laminating, cov ntawv sau dawb yog zoo tagnrho thiab nws cov ink txheej plawg heev nyias.
2. Siv tus lej thev plaub
Tus cwj mem kua ntiv taw yog ib hom khoom uas ua rau cov xim ntawm cov cwj mem xiav lighter. Feem ntau siv cov cwj mem kua siv rau cov neeg ua haujlwm muaj xws li dawb cwj mem, roj ntsha roj thiab roj roj.
Dawb cwj mem yog ib hom cwj mem, uas muaj cov kab dawb dawb pigments, txuas cov ntaub ntawv thiab lwm yam ntaub ntawv. Nws yog siv rau xim lub teeb xim luam ntawv, qhov muag xim xim thiab trademark qauv luam ntawv. Lub plhu dawb dua yog muaj kev lim tiam, uas tsis nruj sib xyaws nrog cov phom. Tom qab luam tawm, cov phom yuav txav mus rau hauv ntawv sai sai, thiab cov xim yuav ntab rau hauv daim ntawv thiab tabkaum ntawm kev tawm. Qhov no yog vim muaj qee cov teeb uas muaj tsos kob cov xim muaj ntau zuj zus. Qhov ua rau ntawm zaj duab xis.
Xim npav yuav tsum ua tib zoo xaiv ua ntej luam ntawv, thiab tus neeg ua haujlwm rau tus kheej nrog rau kev ua tib zoo thiab tsis muaj cov ntsiab lus tseeb yuav tsum siv los ua tus neeg sawv cev ua haujlwm.
Cov roj ntsha sib daj sib npaug yog ib qho zoo li lub pob zeb uas ua los ntawm kev sib tsoo thiab ntxig txhuas hydroxide thiab cov zaub roj hauv av. Nws siv tau los ua kom cov gloss ntawm cov ntawv luam tawm thiab muaj kev luam ntawv zoo heev. Txawm li cas los xij, tus txhuas hydroxide yog lub teeb thiab yuav ntab rau ntawm cov inkstone txheej tom qab luam ntawv. Thaum cov yeeb yaj kiab coated, ib qho pom tsis muaj kab sab nrauv yog tsim ntawm cov nplaum thiab lub plhaub txheej, uas ua rau neeg pluag los sis ua npuas ntau heev. Nws yog qeeb qis rau nws tus kheej, thiab nws kuj muaj cov cuab yeej ntawm inhibiting number case ziab, uas yog qhov nyuaj rau hloov lub txheej.
Bright oil yog ib tus neeg tuaj yeem qhuav ntawm sab nraud mus rau sab nrauv. Nws yog ib qho khoom siv pob tshab ntawm cov pob zeb, cov roj zaub, thiab cov khoom ua si. Nws muaj ib qho zoo nkauj, ib zaj dab neeg zoo nkauj, thiab ib qho kev zoo. Cov xuab zeb polypropylene tuaj yeem muab cov adsorbed tso rau ntawm tus lej ntawm cov xoom txheej. Nyob rau tib lub sijhawm, cov roj qaim yuav ua rau cov duab prints glossy thiab qhuav sai dua, kev luam ntawv zoo yog qhov zoo. Yog li ntawd, nws yog ib qho zoo ntawm tus cwj mem ink.
3. Hom luam ntawv number case
Cov yeeb yaj kiab-npog cov khoom yuav tsum ceev ceev tsau npo offset. Cov phev yog tsim los ntawm cov khoom cua, khoom noj roj, kub-roj kerosene, thiab me me ntawm cov pos hniav. Synthetic reactive molecules muaj polar pawg, thiab polar pawg yuav yooj yim heev diffuse thiab permeate nrog pawg polar hauv lub nplaum molecules, thiab tsim kev sib txuas ntawm kev sib txuas, tsim lub cev thiab tshuaj ua kom qis, uas yog qhov tsim kom muaj txheej; yoo kho Qhov kev yees duab offset number no kuj muaj qhov kom zoo ntawm kev ziab ntawm lub plhaub txheej tom qab luam ntawv, thiab kuj zoo heev rau cov txheej txheem. Txawm li cas los xij, nws tsis yog tswv yim los muab ntau cov khoom muag thaum siv nws. Txwv tsis pub, tus ntiv nplhaib ntawm cov xoom txheej yuav ua kom tawv nqaij, uas yuav cuam tshuam cov yeeb yaj kiab coating.
4. Ntxiv rau qhov av chiv
Yuav kom yoog rau kev ua haujlwm siab-ntau xim, cov ntawv luam ntawm kev txhim kho feem ntau yog siv los daws cov teeb meem ntawm sab nraub qaum.
Txau yog feem ntau ntawm cov cereal starch thiab cov khoom raug tshem tawm. Cov nyhuv siv tshuaj tua kab mob ntawm cov plua plav yog tsuas yog tsim los ua ib qho kev tsis tuaj yeem rau saum npoo ntawm cov xoom txheej, uas yog txo cov adhesion. Vim yog cov coarse particle, yog tias ntau plua plav yuav tsuag thaum txheej txheem luam ntawv, cov khoom ntab saum nplaim ntawm cov ntawv luam tawm. Thaum cov yeeb yaj kiab coated, cov nplaum tsis tuaj yeem ua rau lub khob rau ntawm txhua qhov chaw, tab sis theej adheres rau txheej txheej ntawm hmoov av hmoov av, ua rau ua qhov tseeb. Viscosity tau cuam tshuam loj heev rau qhov zoo ntawm txheej. Yog li, yog tias cov ntawv luam tawm yuav tsum tau coated, npaum li cas cov hmoov av yuav tsum tswj kom ntau li ntau tau thaum luam ntawv.
Cov neeg pluag ziab ntawm tus cwj mem ntawm qhov teeb meem luam tawm tau muaj kev raug mob loj rau qhov zoo ntawm zaj duab xis. Cov cwj pwm uas cuam tshuam rau ziab ntawm lub plhaub zauv txheej, ntxiv rau hom cwj mem, qhov nyiaj thiab hom driers hauv kev luam ntawv, thiab qhov kub thiab txias ntawm luam ntawv thiab cia, cov qauv ntawm daim ntawv nws tus kheej kuj yog heev tseem ceeb. Yog hais tias tus qauv ntawm coated ntawv thiab offset ntawv yog txawv, qhov ziab zis ntawm tus number case txheej yog txawv.
Seb nws yog coated ntawv los yog offset ntawv, zaj duab xis yog them thaum lub cwj mem tsis yog kiag li qhuav, thiab tus cawv ntawm qhov zoo ntawm cov txheej coating yog unfavorable. Cov kaus poom uas kub hnyav uas muaj nyob hauv tus cwj pwm tau yooj yim ua rau cov yeeb yaj kiab los nthuav thiab txhim kho, thiab qhov nthuav dav thiab kev loj hlob ntawm cov yeeb yaj kiab yuav yog qhov tseem ceeb tshaj rau cov tshuaj thiab cov khoom ntawm cov khoom tom qab cov yeeb yaj kiab.
