Nws yuav tsum raug sau tseg tias txawm tias qhov nyiaj ntau npaum li cas, qhov sib txawv ntawm gloss tuaj yeem txo, tab sis qhov kev ntsuam xyuas no nws tsis ywj pheej ntawm cov txheej (vim siv cov coatings ntawm cov tuam txhab txawv).
Ntawm qhov tod tes, coated paperboard rau ntawm lub tshuab yuav muab ib tus npliag zoo dua txhua lub sijhawm siv tib yam xim ntawm cov xim. Qhov txawv ntawm cov ntaub ntawv lo rau ntawm peb cov cav tov tuaj yeem hais tau los ntawm kev sib koom ntawm kev siv tshuab hmoov xim, lub tsho xim, thiab kev ua haujlwm.
5 Nws yog ib qho tseem ceeb uas yuav tau xaiv txoj hlua ntawm txoj cai
Cov number case muaj ob qhov teebmeem ntawm cov txheej pleev xim:
Vim yog lub plhaub ntawm lub plhaub tws, qhov tsis zoo ntawm cov txheej kom ntu ntawm daim ntawv xa tawm ntawm daim ntawv luam tawm tsis tuaj yeem txaus los ntawm lub substrate. Vim li no, cov degree uas tus number case yog sib xyaw nrog cov txheej no nyob ntawm qhov ua rau ob leeg.
Cov lej uas nyuam qhuav tau luam tawm tau pib ua kom nws qhuav, thiab txawm tias ob txheej txheej txheej, lub ultraviolet (UV) txheej, nws khov lawm, nws qhov ziab mus txuas ntxiv mus hauv qab no. Qhov no yuav ua rau lub cev ntim ntawm lub txheej thiab tej zaum yuav cuam tshuam los ntawm cov khoom thaum lub sijhawm oxidative. Cov kev sib txuam no ua rau txo qhov tawg thiab ua txhaum daim ntawv cog lus.
Vim yog qhov sib thooj ntawm ob, qhov gloss ntawm ultraviolet (UV) glaze nyob ntawm seb hom ntawm cov xaum xaiv. Yuav kom paub meej tias muaj qee cov ntsiab lus ntawm qhov ci ntsa iab, yuav tsum siv yawm sij haum hauv tsev. Txawm li cas los xij, number case tej zaum yuav raug tsim los txo qis ntawm qhov nqus. Thaum tus thawj chav luam ntawv siv tus cwj pwm xaj uas siv ultra-fast, nyob rau hauv chav tom ntej, tus number case yog faib thiab pauv mus rau daim pam los tsim cov cim tshwj xeeb. Yog li ntawd, nyias muaj nyias yam yuav tsum tau saib xyuas nyias. Kev daws cov dampening yuav tsum siv tsawg li sai tau thaum luam ntawv, uas txo cov zauv ntawm tus lej ntawm daim pam thiab txo cov teeb meem ntawm cov zauv ntawm cov ntawv. Cov cwj pwm siv los kuj tseem muaj feem xyuam rau qhov teeb meem uas nyob sab nraum qab ntawm pawg nqa khoom yog qhov tsis huv.
6 primer khoom
On-line ultraviolet (UV) glazing yog siv rau cov pa roj carbon dioxide, feem ntau yog nrog ib txheej dispersion. Cov tshuaj tiv thaiv kab mob hauv nruab nrab thiab cov tshuaj ultraviolet (UV) yog cov tshuaj tsis sib xws, thiab qhov "nruab nrab lo" yuav tsum siv rau hauv daim ntawv ntub, ntub daim ntawv lub sij hawm luv luv. Cov dej sib xyaw dispersion synthesis muaj 40% rau 45% solids, thiab viscosity ua haujlwm ntawm kub tau muab kho los ntawm kev ntxiv dej.
Thaum cov dispersion txheej yog siv rau daim ntawv, ib qho tseem ceeb ntawm cov dej noo yuav tsum tau kos rau hauv lub substrate thiab ib txhia yuav ploj. Tsuas yog lub sijhawm no, lub polymer pib nws txoj kev los cuam tshuam rau kev tsim cov yeeb yaj kiab txheej. Yog li ntawd, nyob rau hauv txheej txheem tsim muaj hauv online, cov ntaub ntawv qhia yuav tsum muaj peev xwm qhuav sai li sai tau. Qhov ua kom zom zaws tau yooj yim, ua kom yooj yim, nkag mus, muaj zog tshaj, muaj zog, gloss thiab adhesion nyob ntawm seb cov khoom siv thiab cov khoom siv ntxiv.
Qhov tseem ceeb ntawm cov khoom siv primer tuaj yeem pom tseeb los ntawm kev nce qib hauv kev siv thiab siv ntau hom khoom siv primer. Tshwj xeeb tshaj yog nyob rau saum npoo nrog siab number case, qhov cawv ntawm cov khoom siv primer ntau dua.
Hloov lub 13m3 / m3 anilox yob nrog 18cm3 / m3 anilox yob. UV (UV) lo yog smoother thiab muaj lub siab dua gloss. Qhov no yog qhov tseeb tshwj xeeb tshaj plaws nyob rau hauv cov chaw muaj kev kub ntxhov.
Peb tuaj yeem txheeb xyuas qhov teebmeem ntawm ntau hom khoom siv primer. Cov kab mob loj heev nyob ntawm thaj chaw ntawm 200% ntawm cov av tsuas pom thaum siv cov phom feem ntau. Cov ntawv nyuab primer tshwm sim kom muaj ib tus ntug ua ntej UV (UV) glazing. Txawm li cas los xij, qhov khawb ntawm qhov khaus yog txo. Qhov me me qhov nyiaj siv, qhov ntau dua qhov tus ntawm cov hom primer khoom. Cov kev ntsuam xyuas no qhia meej meej tias qhov ziab ntawm cov txheej txheej tseem ceeb heev. Yog tias lub sij hawm ziab thiab lub sij hawm qhuav zom tsis txaus ua ntej ultraviolet (UV) glazing, uas yog, siv qhov zoo tshaj plaws primer thiab zoo npaum li cas, qhov zoo tshaj plaws gloss tsis tau tiav. Yog li, siv ob lub coaters rau glazing, nws pom zoo kom siv ib lub tsev qhuav qhuav.
7 ultraviolet (UV) glazing txheej
Niaj hnub no, sib cav sib zog kho ultraviolet (UV) glazing coatings feem ntau siv rau hauv kev lag luam luam tawm. Cov ultraviolet (UV) coatings muaj ib phau ntawv, ib qho tshuaj tsis sib haum, thiab ib tug yees duab. Nyob rau hauv ultraviolet (UV) lub teeb, qhov tshwm sim hauv lub network tshwm sim los kho tus txheej txheem. Ultraviolet (UV) lub teeb ua rau tus neeg pleev kob los tso tawm cov tshuaj lom neeg, ua rau lub pob txha los ua lub cev kom tsim tau cov hlua sib txuas ntev. Cov pa tawm cov tshuaj tiv thaiv no.
Rau cationic hardening coatings, ultraviolet (UV) lub teeb initiates ion tsim thiab cov saw cov tshuaj tiv thaiv ntawv. Vim yog lub rooj sib txuas ntawm txoj kev kho, tab sis kev ceev ceev yog qeeb, nws tuaj yeem kho tau. Cov hau kev ntawm cov cationic hardening ultraviolet (UV) glazing coatings feem ntau yog siv rau hauv cov zaub mov ntim vim lawv tsis muaj ntxhiab thiab muaj zog heev kom huv si. Peb cov kev tshuaj ntsuam xyuas los ntawm sib sib zog sib zog (UV) glazing coatings.
Nce tus nqi ntawm UV coating yuav ua rau kom ci ntsa iab, tab sis cov nyhuv tsis zoo li nce ntxiv npaum li cas. Thaum kuaj, tus nqi ntawm UV txheej yog nce ntawm 20 cm 3 / m 3 mus rau 30 ccm 3 / m 3, thiab gloss ntau zog los ntawm tsawg kawg 10 ntsiab lus tsis hais txog qhov kev pab cuam ink. Thaum txiav txim siab txog tus nqi ntawm UV txheej, tsis txhob hnov qab tias nws tsis yooj yim rau kev thov khov kho yog hais tias tus nqi loj heev vim yog qhov ua kom siab. Cua kub hauv UV lo rau 40 ° C yuav ua kom muaj zog thiab ua rau kom ci ntsa iab dua.
Ntxiv mus, qhov geometry ntawm lub anilox yob kuj muaj feem xyuam rau kev khiav ntawm cov txheej. Ntxiv nrog rau qhov muaj peev xwm, tus naj npawb ntawm cov kab txuas network kuj ua haujlwm. Tsuas yog ib lub tsho uas tsis yog-foamed ua ib qho zoo gloss. Thaum lub anilox dov ntawm tes tau ntim nrog cov xim, nplua npuas daim ntawv micro-ua npuas ncauj rau hauv cov xim. Cov xwm txheej no tuaj yeem ua ke nrog kev kho kom zoo dua qub, nrog rau kev sib xyaw ua ke ntawm cov xim muaj hlau ua kom pom tseeb tias cov xim tsis pub dhau.
8 ziab yog qhov tseem ceeb
Nyob rau hauv ib qho teeb meem ntawm vib nas this, cov khoom muab cov xim thiab gloss yog siv rau lub substrate. Thaum tus neeg xa khoom sim ua kom cov khaubncaws sab nraud povtseg hloov sai sai los ntawm cov kua rau cov khoom, kev kub ceev luam tawm muaj cov kev txwv. Yog li ntawd, qhov txheej txheem glazing yuav tsum tau txais kev txhawb los ntawm txoj kev tu kom qhuav.
1 ziab yog txiav txim siab los ntawm kev ceev zus
Kev kub ceev yog qhov tseeb uas peb xav tau, tab sis nws yog ib qho tseem ceeb kom nco ntsoov tias txoj kev ziab piav qhia yog tsuas siv tau rau cov cuab yeej kom qhuav. Raws li qhov ceev ceev nce, nws yog qhov nyuaj heev kom qhuav thiab tawv. Tom qab luam ntawv, qhov teeb meem no tshwm sim ncaj qha rau sab qaum thiab sab qis ntawm kev xa khoom tuaj. Yog tias nws pom, nws raug hu rov qab smearing. Cov yam ntxwv zoo ntawm UV glazing prints yuav stabilized tom qab ob peb hnub. Gloss thiab bond bond yuav txawv tom qab 24 teev, nyob ntawm seb tus number case thiab txheej siv. Txawm li cas los, kev hloov tsis yog ib qho kev tsis zoo.
Txhawb kom ruaj ntseg ntawm qhov chaw ntawm high-speed hardening lo, tom qab ziab, nws tsis muaj cai hloov hauv kom. Cov ntawv txheeb tau los ntawm ib qho ntawm ib qho ntawm cov khoom xa tuaj thiab raug rau kev txiav txim siab. Yog li, qhov chaw ntawm cov nplooj ntawv yuav tsum tau ua kom tsis txaus los xyuas kom meej tias lawv tsis raug mob los ntawm kev sib cuag nrog sab nraum qab ntawm daim ntawv teev lus tas. Qhov no hardened yog los ntawm UV qhov nqaj ziab drying ua qhov tsim kom muaj qhov nqaj zog.
Kev ziab ua rau qhov kub ntawm qhov khoom thauj ntawd nce siab, ua rau rov qab ua qias neeg thiab txawm tias daim ntawv lo. Yog li ntawd, nws yog ib qho tseem ceeb tshaj plaws los siv qhov kom qhuav tsim nyog thaum tsim nyog. Yog li, tom qab luam ntawv thiab glazing ntim, infrared (IR) roj yuav tsum tau cia, ntxiv rau cov cua kub thiab kub thiab siv. Nws raug nquahu kom siv ob hom ntaub ntawv ntawm kev tu ncua qhov nruab nrab ntawm ob lub coaters. Yog hais tias nws tsuas yog lub sij hawm qhuav zom zaws, uas yog qhov kev hloov qis dua, ces ib qho kev hloov ntxiv ntawm ob lub tsho loj kom ntseeg tau tias cov zis ntau yuav nce tau ntxiv los ntawm 40% uas tsis cuam tshuam rau cov nyhuv loj. Lub zog tso zis ntawm chav tsev ziab tshav kub yuav tsum ua kom zoo tshaj qhov qub. Lub zog ntawm UV yuav tsum ua raws li cov kev ceev ntawm cov xovxwm, tab sis txoj kev sib raug zoo ntawm nonlinear. Lub zog tso zis ntawm IR yog linear.
Ua raws li cov nias ntawm cov nias nce, qhov gloss txo thaum cov kev hloov pauv cov ntaub ntawv. Raws li tau piav saum toj no, lub caij nyoog ntawm qhov txheej txhua txheej yuav txiav txim siab qhov "ruaj khov txheej" uas ruaj khov. Daim ntawv txav ntawm cov chav luam luam ntawm kev ceev ceev ntawm 10,000 nplooj ntawv ib xuab moos, thiab tus number case penetrates rau hauv ntawv tsawg dua ib pliag. Cov kev kuaj no qhia tau hais tias gloss ntawm cov ntawv luam tawm ntawm cov ntawv luam tawm thawj zaug thiab cov ntawv luam tawm thaum muab piv rau cov qis tshaj li qub, uas ua rau qhov tsis zoo ntawm lub chav tsev luam ntawv kawg. Cov xwm txheej no tuaj yeem raug siv los ua ib qho kev siv, uas yuav pab tau peb los teeb tsa qhov kev teeb tsa thiab txiav txim siab cov xim ntawm cov xim. Txawm li cas los xij, thaum luam ntawv nrog cov npuav tib lub ntsiab, lub ci ntsa iab yog degraded raws li cov ntawv luam tau nce, thiab qhov teeb meem qhov teeb meem ntawm tus cwj pwm no yog ib qho tsis muaj kev cuam tshuam. Nws tau raug hais tias qhov xim txuam ntawm inks, coatings thiab ziab cov cuab yeej ua rau txo qhov tsis zoo.
Cov nyhuv uas ultraviolet (UV) glazing tuaj yeem nyob ntawm qhov tsuas yog siv rau hauv substrate. Cov nyhuv ntawm txheej txheej high gloss dispersion txheej rau ib lub substrate, cov nyhuv yam ntawm UV (UV) glazing rau zoo li ib lub substrate, muab ib qho kev siv rau cov kev pab them nqi siab uas muaj peev xwm ua rau gloss Nws txo, tab sis nws yog ua tau kom txhim kho lub tshooj ntawm tus number case thiab nws cov adhesion rau primer los ntawm kev siv lub siab concentration ntawm pigment thiab ib tug cwj pwm absorbent, thiab adhesion yog ruaj khov heev ob peb hnub tom qab luam ntawv. Ua tib zoo xaiv cov hom thiab cov nqi ntawm cov siv primer siv, uas yog qhov kev txiav txim siab rau cov paj nruag.
