Ntau cov technologies hauv kev lagluam luam tawm tau tawm ibqho ntxiv, thiab ib qho ntawm cov technologies ceev tshaj plaws yog lub zog curing siv tshuab. Nws txhais tau hais tias tus number case los yog glazing txheej yog tsau los yog tawv rau hauv substrate nyob rau hauv irradiation ntawm radiant zog kom tau txais ib daim ntawv luam qhuav. UV lub teeb thiab ceev zog siab electron beam (EB) yog ob hom kev siv hluav taws xob rau kev siv hluav taws xob tshuab. Xws li, cov phev tshuaj kho uas siv kho UV thiab EB zog, feem ntau yog raug xa mus rau UV phev thiab EB hauv qab. Vim zoo tu cov nyhuv thiab qaug qis, tus nqi ntawm kev siv kuj tau raug txo qis rau xyoo tas los, yog li nws yog nce ntxiv los ntawm cov luam ntawv.
Tsab xov xwm no yuav tsom xyuas txog qee cov teeb meem ntsig txog EB curing inks.
Lub curing txoj cai ntawm EB number case
Kev ziab ntawm lub plhaub zauv txheej tom qab luam tawm ntawm tus cwj mem zis yog tias cov khub (hnyav, roj) hauv absorbed thiab volatilized los ntawm cov substrate, thiab cov khoom teeb meem (thaij, xim, siv quav ciab, khoom noj khoom haus, thiab lwm yam) qhov saum npoo ntawm cov substrate los tsim Ib txheej txheej ntawm tus cwj mem. Kev ziab ntawm cov phaw twj thiab kev kho lub zog ntawm txoj hauv curing kuj sib txawv ntawm cov xaum xim ntawm cov cwj mem xiav / glazing coatings, thiab ob qhov seb lub tshuab luam ntawv yuav tsum tau nruab nrog zog tua cov khoom.
Txheej txheem ntawm kev ziab cov ntsiab lus ntawm EB inks thiab ntau cov phaw
EB curing yog ib hom kev tua hluav taws. Nws yog ib txoj hauv kev uas siv hluav taws xob hauv hluav taws xob ua ib qho hluav taws xob los ua kom muaj kev sib hloov ceev ceev ntawm ib qho tshwj xeeb uas muaj 100% reactor ua kua rau hauv cov khoom. Lub hauv paus ntsiab lus yog: thawj zaug, lub tshuab hluav taws xob ua ke tshuam nrog lub txheej los yog kua qaub ntim khoom los mus ua rau hauv cov dawb radicals; ces, cov dawb radical reacts nrog C = C ob leeg nyiaj los tsim ib txoj kev loj hlob saw; Thaum kawg, txoj hlua loj hlob thiab cov tsho los yog tus cwj mem los ntawm lub plhaub Qhov feem xyuam ua rau kev sib tshuam ntawm kev kho kom zoo thiab nce qhov sib npaug ntawm qhov kev sib tshuam. Vim tias lub tshuab hluav taws xob muaj zog loj tshaj plaws, qhov tshwm sim saum toj no feem ntau tshwm sim los ntawm cov kev tsis zoo tshwm sim xws li molecular degradation, molecular ion rearrangement thiab cov zoo li no. Yog li EB kho txheej ua ntau ceg thiab ntau dua ntais ntawv.
Txoj kev kho EB yuav tsum tau siv cov khoom siv curing tshwj xeeb. Cov ntsiab lus ua hauj lwm yog raws li nram no: Tom qab cov electrons tau tawm los ntawm ib txheej ntawm cov cathode linear daim hlau, ib lub teeb ntsug tib lub teb hluav taws xob yog ceev, thiab ib qho ntaub ntawm electron nqaj yog tau txais nyob rau hauv lub thawv lub raj npog irradiation. Vim tias lub xov xwm irradiated ze rau ntawm cov hluav taws xob, nws qhov tsis sib haum zog tsis siab (tsawg tshaj li 500 kV), tab sis lub hwj chim siab dua vim yog cov zis loj. Cov phom cathode phom yog cov kev cog lus ntau dua cov khoom siv roj ntsha, yooj yim dua los nruab rau ntawm cov kab ntau lawm, thiab yooj yim dua cov ntaub thaiv npog.
EB curing technology nta
Raws li kev kho tshuab curing tshiab, EB curing muaj qhov tshwj xeeb zoo tshaj rau cov cuab yeej siv tshuaj curing.
Tus thawj EB number case kho lub sij hawm luv heev, feem ntau tsuas yog 1/10 vib nas this kom qhuav thiab txhim kho rau ntawm lub substrate. Rau cov tshuaj thermosetting thaus liv thiab cov ntawv ua noj, lub sij hawm ziab yuav siv li ob peb feeb los yog qee lub sijhawm Nws tsuas siv sijhawm ib hnub kom qhuav, yog li siv cov tshuab hluav taws xob ua haujlwm luam tawm cov haujlwm luam tawm haujlwm luv luv, kom flexo thiab gravure, thiab zoo heev txhim kho qhov tsim tau ntawm offset printing.
Lub zog EB yuav tsum muaj rau qhov kev kho thib ob ntawm 150 txog 300 keV. Nws nce mus txog ntawm cov ntaub ntawv kho kom zoo ntawm qhov ceev ntawm lub teeb, tsis tsuas yog tsis txwv los ntawm cov xim ntawm cov txheej, tab sis kuj kho cov nplaum ntawm txheej hauv daim ntawv los yog lwm cov substrate thiab opaque substrate ( xws li cov ntawv ci txhuas).
Qhov thib peb EB txoj cai pub rau 100% kev kho cov coatings, mog thiab tshuaj nplaum, tshwj xeeb tshaj yog nyob rau cov cheeb tsam uas qhov kev kho yuav tsum yog 100%, xws li cov khoom noj mov.
Qhov thib peb sau luam tawm nrog energy-curable number case muaj zog tsis kam. Cov khoom siv tshuaj hauv cov cwj pwm ua piv txwv cov duab polymer uas muaj peb sab los ntawm kab kev sib txuas, thiab tus ntiv taw xau muaj zog tshuaj tiv thaiv thiab txhuam kev sib tw.
Cov ntsiab lus ntawm cov plaub ntawm EB tom qab tua tau ze rau 100%, thiab feem ntau tsis muaj VOC (organic volatiles), uas ntseeg tau tias EB kua number case dua tus phooj ywg ntau tshaj li cov pa number case. Piv txwv, cov tshuaj hauv EB hauv thev naus laus zis yog zoo zoo, thiab cov ntxhiab ntawm ntau tus tib co zoo tib si los ntawm oxidized conjunctiva ntau me dua, thiab qhov teeb meem ntawm cov ntawv luam tawm yog huv thiab tsis muaj av.
Thib 5 Nrog txoj kev siv technology, cov nyhuv ntawm EB-curing ntawm cov tawv nqaij ntawm cov tawv nqaij ntawm cov tib neeg tej tawv nqaij yog tau me thiab me dua, thiab nws zoo ib yam li tus qauv qub uas muaj cov roj av feem.
Qhov kev siv zog thib rau qis yog tsawg, EB curing zog noj yog 5% ntawm UV curing, thiab 1% ntawm cov cua sov ua kom pom tseeb. Yooj yim rau kev khiav lag luam, yooj yim los tswj, siab raug thiab repeatability, tsis muaj kev tswj hwm huab cua.
Kev tsim kho ntawm EB curing technology thiab daim ntawv thov mus luam
Tamsim no, EB curing tshuab tau siv ntau hauv kev luam ntawv, luam ntawv thiab luam yeeb.
EB inks yog tshwj xeeb cov phev ua uas kho nrog electron beam zog. Presses uas siv EB hauv thom khwm yuav tsum muaj cov yob tshwj xeeb yob, cov ciav ntsiab, thiab cov tshuaj ntxuav vim hais tias EB gondola ntawm qhov txawv ntawm cov pa hauv plhaws.
Thaum xyoo 1970, lub Tuam Tshoj Ford tau siv EB curing technology rau lub tshuab ua ke thiab cov twj siv twj paj nruas rau thawj zaug, uas yog tus thawj coj ntawm EB curing technology rau industrial ntau lawm. Thaum tib lub sijhawm, Album Printing siv EB curing inks thiab coatings rau cov khoom ntim.
Thaum ntxov EB kho cov tswv yim tau txwv tsis pub luam tawm lossis glazing ntawm cov ntaub ntawv hauv web. Qhov no yog vim hais tias nyob rau ib daim ntawv-noj fes, tus gripper kab tuaj yeem cuam tshuam nrog X-ray shielding uas ua los ntawm txoj hlua electronics. Nyob rau ntawm lub vev xaib, EB chav tsev tua hluav taws nyob rau ntawm qhov kawg ntawm xovxwm thiab txuas tau yooj yim mus rau cov khoom siv hauv web uas tsis muaj kev pab. Qhov teeb meem tam sim no tau daws los ntawm kev ua haujlwm tas mus li ntawm cov neeg ua haujlwm R & D. EB curing siv tshuab tau dav dav siv hauv daim ntawv ntawm cov ntawv folding sheetfed, cov ntawv luam tawm luam tawm thiab cov zoo li.
Niaj hnub no, EB tua tshuab zoo siab tau ua qhov kev xaiv zoo tshaj plaws rau kev luam ntawv yooj yim. Qhov no tsis yog vim nws ua kom muaj kev tiv thaiv ib puag ncig xwb, tab sis kuj vim tias nws zoo tshaj plaws luam ntawv zoo thiab qhov pheej yig poob rau hauv cov nqi ntawm cov khoom siv EB tua (EB tua cov khoom tau nqis los ntawm thawj daim ntau tshaj li 1 lab cov nyiaj US $ 200,000 rau hnub no Tebchaws Asmeskas las, thiab kuj Muaj ib txoj kev poob qab ntxiv). Qhov kev cuam tshuam loj tshaj nyob rau hauv daim ntaub ntawv EB yog nws daim ntawv thov ntawm CI (central lub tswv yim kheej kheej) cov ntawv cim npe flexo. Thaum lub sij hawm luam ntawv, tus number case ua tiav ntub dej ntub tsis dhau qhov tsis ziab tom qab txhua xim luam ntawv tiav. Nrog lub tshuab EB, nws tsuas yog tsim nyog kom dhau txoj kev tiv thaiv kab mob EB kom sai thiab kho kom qhuav cov substrate, uas yog, "tshuab ziab" hloov qhov ntau ntawm cov tshuab drying hauv kev luam ntawv.
Nyob rau hauv daim ntawv lo luam, EB glazing kuj tau siv dav. Qhov txawv ntawm EB kua roj voos thiab EB dawm yog qhov qub tsis muaj pigment. Hauv UV glazing, txhawm rau kom tau zoo gloss, ob chav txheej feem ntau ua tau. Thawj cov txheej txheem cov txheej txheem costraction nrog cov txheej txheem dej uas muaj cov kab dej tawm ntawm tus UV varnish los tiv thaiv kev fab tshuaj thiab luam tawm cov duab nraaj thiab cov duab tsis yog ntawm daim luam tawm. Cov kab mob me me tau ntim lawm; qhov txheej txheem thib ob yog coated nrog UV varnish los muab cov khoom luam tawm zoo dua cov ntawv luam tawm. Qhov no yuav tsum tau mus txog rau peb lub tshuab cua kub kub kom ua tiav qhov ziab ntawm kev luam. EB kho tau zoo heev ntawm kev muaj peev xwm kho tau cov quav hnyav dua. EB glazing yuav hloov cov txheej txheem ob-txheej puag-rau-multilayer qauv nrog ib zaj duab xis "single-layer", uas yog txuag cov ntaub ntawv thiab ua kom txo cov nqi tsim nyog. Txheeb xyuas tau pom tias EB txheej ib leeg tuaj yeem txo cov nqi tsim nqi li ntawm 10%. Nyob rau hauv daim teb no, kev ua tau zoo tshaj plaws yog Suntech txoj kev vam meej ntawm cov khoom qis tshaj Sun Tea. Nws raug tso cai los ntawm kev sib cuag nrog cov zaub mov thiab siv tau los ua ib txheej txheej rau khoom noj khoom haus. Hnub no, cov khoom siv tau dav siv, xws li txheej hauv cov ntawv ntim cov ntawv, cov hnab yas, cov thawv khoom noj thiab lwm yam. Muaj ib qho tseem ceeb yuav tsum tau ua tib zoo sib xws nrog cov pa luam ntawv thaum siv EB glazing, raws li waxes thiab lubricants nyob rau hauv cov cim pa hauv cov pa yuav cuam tshuam nrog cov kua nplaum ntawm EB varnish.
Los ntawm kev siv EB curing, txheej txheej txheej uas pib siv ob peb feeb los yog ob peb hnub yuav tsum tau qhuav tas tuaj yeem qhuav qhuav, thiab khiav ntawm kev khiav lag luam yog qhov ua tau pom zoo, uas ua kom zoo tshaj qhov qub txeeg qub teg. Daim ntawv thov EB curing technology tau ua kom luv luv ntawm lub sij hawm luam tawm, cia, glazing mus ntim thiab kev thauj mus los, kom txhua tus txheej txheem ntawm luam ntawv, ci ntsa iab thiab kev ntim khoom thauj tuaj yeem ua tiav nyob rau hauv ib hnub, uas muaj tseeb raws li siab laus ntawm lub caij nyoog niaj hnub . Kev sib deev thiab kev xav tau.
