Flexo luam ntawv tau maj mam ua cov ntsiab lus hauv kev lag luam qib siab kawg. Cov qauv ntawm cov txheej txheem no yog siv UV number case. Vim hais tias tus nqi ntawm flexo UV number case yog kim heev, nws squeezes tus nqi chaw ntawm daim ntawv lo, thiab vim tus UV number case nws tus kheej muaj kev cob qha thiab ib puag ncig, los ntawm kev hloov kho, ink printing + UV glazing yuav hloov cov UV. Flexo luam ntawv txo nqi thiab txhawb kev tiv thaiv ib puag ncig. Qhov no puas ua tau? Ntawm no, tus neeg sau yuav tshuaj xyuas qhov teeb meem no nrog txhua tus neeg.
Cov lus teb rau lo lus nug ntawm tus number case thiab ntxuav
Tam sim no, daim ntawv qhia kev lag luam tseem muaj kev ntseeg txog tus lej zoo, feem ntau nrog rau cov teeb meem hauv qab no: 1 case tsis yoojyim rau cov khoom ua yeeb yam; 2 tus lej dot yog loj dua ntawm cov ntaub ntawv thiab cov ntaub ntawv zaj duab xis, thiab nws yog ib qho nyuaj rau kev tswj hwm; 3 number case Drying sai, tus number case yog yooj yim rau lo rau lub phaj printing, ua rau tsis thaiv kev tsis thaiv; 4Qhov txheej txheem luam ntawv yuav tsum tau soj ntsuam xyuas qhov kev hloov ntawm pH, thiab ntxiv sijhawm ntxiv pH stabilizer, kev khiav haujlwm yog qhov tsis txaus; 5 pH stabilizer muaj dej hauv ammonia, nws tuaj yeem ua rau ntxhiab nyob rau ntawm qhov chaw nyob thiab cov khoom cim npe.
1. Adhesion rau naam
Nyob rau hauv teb rau qhov teeb meem no, qhov tseeb, qhov kev faib haujlwm ntawm number case tuam txhab thiab cov tuam txhab luam ntawv yuav tsum muaj tseeb meej. Ink tuam txhab uas muag yuav tsum paub txog cov khoom sib txuam ntawm lawv cov khoom nrog rau zaj duab xis. Kev daws teeb meem ntawm cov dej-raws li cov yeeb yaj kiab thiab cov yeeb yaj kiab yuav tsum tswj kom nruj, uas yog, qhov sib luag yog zoo sib xws, cov kev tsis sib haum xeeb yog zoo sib xws, thiab kev sib tw tshiab yuav tsum raug tsim tawm. Cov tuam txhab luam ntawv yuav tsum tau siv cov kev sim rau kev tshawb xyuas, xaiv thiab ntsuam xyuas tawm ntawm tus cwj pwm tsim nyog, xyuam xim tsis yoojyim yooj yim, dump tag nrho cov phim uas tseem muaj cov teeb meem, tab sis tsis txhob saib xyuas lub tshuab thiab nce nqi sim.
2. Tshem tawm ntawm zaj yeeb yaj kiab
Txoj kev loj tshaj plaws rau tus cwj mem kom qhuav rau hauv zaj duab xis yog volatilization, ziab yog lub ntsiab txhais tau tias. Yog li no, lub sij hawm ntev mus rau qhov teeb meem ziab no yog ua kom lub cev kub, nce qhov cua ntim, qeeb qeeb lossis txo qis ntawm lub phaj tsho. Muaj kuj yog ib qho hais tias cov zauv kua mis muab faib ua peb theem: qhov ntu qhuav yog nyob ntawm volatilisation, cia noo noo khiav; ces qhov sib txeeb ntawm tus pob txha ntawm cov pob khoom yog tom qab dej ntws tawm; thiab thaum kawg lub pob cwj pwm los ntawm kev sib koom tes (xws li catalyst). Hla-qhov kev sib tawm tsam hauv qhov kev txiav txim).
Ib qho ntawm cov lus sib txawv yog tib yam, uas yog, cov tshooj qhuav qhuav yog volatilized, thiab tsis muaj lwm txoj kev. Tag nrho lwm txoj kev tsuas yog ua raws li los ntawm qhov ziab ziab los tsim cov tshuaj tiv thaiv hauv cov dej kub, nrog rau kev siv lub tshuab ua si. Vim li no, nws tseem zoo siv lub khob ciav hlau qhov ntsuas qhov ntsuas kom ntev ntev ntawm tus cwj pwm kom ntsuam xyuas cov yam ntxwv ntawm cov cwj mem qhuav. Hom no tuaj yeem paub cov zauv ntawm tus cwj pwm qhuav ua ntej lub tshuab nyob rau ntawm lub tshuab, thiab txiav txim tau qhov tsis ua rau luam ntawv ntawm lub tshuab. Npaum li cas.
3. Lub caij nplooj ntoos zeeg nthuav tawm hauv kev luam ntawv
Qhov txawv ntawm qhov luam tawm yog dab tsi? Hauv qhov tseeb, tus lej ntawm tus cwj mem qhuav, tus xauv npo ntawm tus number case thiab tus UV number case tsis yog nyob rau ib theem, thiab qhov txawv ntawm ob yog 1-2 zaug. Nyob rau hauv lwm yam lus, qhov nthuav ntawm tus number case dot yog hais txog nws cov low viscosity. Tom qab ntawd, tuaj yeem siv cov tshuaj pleev kom siv tau cov teeb meem ntawm kev nthuav dav hauv lub network? Cov lus teb yog muaj. Daim duab hauv qab no qhia txog 150 tus kab / ntiv tes 1% dot thiab 175 kab / ntiv 1% dot luam tawm uas muaj siab khov viscosity. Los ntawm cov kev sib koom ntawm kev sib txuam ntawm cov uas nyob ib sab, txoj kab uas hla ntawm qhov dot tuaj yeem txawv qhov txawv. Lub khob ntawm tus cwj mem xau yog 15dPa s, uas yog ob zaug tus viscosity ntawm UV number case (7dPa s).
Vim li cas kuv tuaj yeem luam tawm tau zoo li tus lej no? Vim tias lub tsev loj uas muaj lub khoob khoob khuav loj dua qub, yuav siv tsis tau tus lej-khaus (viscosity number ink) yog tias lub tsev pheebsuab uas raug kaw khomob siv. Lub hauv paus ua rau kev txiav txim siab txog tus cwj pwm ntawm tus cwj pwm xaws yog cov qauv ntawm cov chav tsev ntawm cov flexo nias. Nyob rau tib lub tsev luam, UV number case yuav siv tau rau siab khov. Vim li cas koj yuav tsum siv qis qis thaum siv tus number case?
4. Yooj yim kom qhuav ntawm lub phaj
Kev vam meej ntawm UV flexo printing yog vim UV number case muaj ib qho tseem ceeb heev feature, uas yog, qhov nro tsis nruj heev, feem ntau ntawm 31 ~ 32mN / m, seb nws yog Hanghua UV number case, los yog Shengweike los yog Flint UV inks, cov ntaub ntawv ntawm qhov kev ntsuas nrawm ntawm txhua yam nyob hauv qhov no. Uas yog hais, qhov nro qhov nrawm ntawm UV number case yog tshuam, thiab qhov nro ntawm qhov ob tuaj yeem sib khi los ntawm kev xaiv ib qho kev tsis haum siab nrawm ntawm lub phaj luam ntawv. Ib yam li, thaum siv cov ink printing, tsuav yog koj tswj qhov kev sib tsoo ntawm qhov kev sib tsoo ntawm cov ntawv xov xwm thiab tus number case, koj tuaj yeem tau txais kev tu tus kheej ntawm cov ntawv xov xwm kom tsis txhob cuam tshuam ntawm kev txhaws tsis ua haujlwm.
5. Khawm pH thiab nws txoj kev ruaj ntseg
Tus cwj mem yuav tsum ntsuas thiab kho thaum lub sij hawm, uas ua rau cov neeg tsav tsheb tsis txaus siab tsis txaus. Yog li, hauv cov txheej txheem luam ntawv, puas muaj cov cwj mem uas tsis saib xyuas thiab kho tus pH? Cov lus teb yog muaj, tab sis koj yuav tsum kawm kom ntsuam xyuas ntau ntawm tus cwj mem. Hauv kev luam ntawv, qhov laj thawj tseem ceeb rau lub plhom ntawm tus nqi pH ntawm tus cwj pwm yog evaporation ntawm ammonia dej li stabilizer, thiab evaporation ntawm ammonia dej yog qhov ua rau pH fluctuation ntawm tus number case. Tom qab ntawd, yog tias muaj tus lej tsis muaj ammonia, lo lus teb yog muaj. Qhov tseeb, txheej txheem dej hauv ammonia tsuas yog ib qho ntawm peb txoj kev loj ntawm aqueous rein amination. Lwm cov txheej txheem ob, txheej txheem organic amine thiab cov txheej txheem alkali inorganic, yog ob txoj kev nrog zoo stability hauv tus number case.
Kev siv cov organic ammonia los yog kev xyaw ua dej caw tsis muaj ammonia no twb yog cov txheej txheem rau cov kua mis ntau lawm. Ntxiv mus, tus number case uas tsis muaj ammonia yog yooj yim li UV number case hauv kev siv, thiab tshem tawm cov ntxhiab tsw ntawm tus cwj mem. Qee lub cev tam sim no ntawm kev ua lag luam tseem siv ammonia ua tus stabilizer, vim yog cov nqi tsim nyog thiab tus nqi xav tau. Yog li, rau lub tuam txhab luam ntawv, thiaj li ua tus nqi pH ntawm tus number case number case ruaj khov thaum lub sij hawm luam ntawv, thiab nws tsis tas yuav saib xyuas thiab kho txij li ib lub sijhawm, lub ntsiab lus dag hauv kev kuaj xyuas ntawm tus number case, tshwj xeeb tshaj yog nyob hauv kev kuaj tej yam kev mob.
Vim li cas peb tseem xav tau UV glazing?
Lub ntsiab ntawm tus cwj pwm xaj yog dej-dispersed hloov acrylic. Thaum tus cwj pwm xiav yog qhuav, nws yog irreversible rau dej, tab sis nws tsis tas yuav ua rau ntau hom tshuaj lom neeg. Piv nrog rau tus cwj mem piv txwv ntawm UV inks, tseem muaj qhov khoob ntawm lub cev ntawm cov yeeb yaj kiab ntawm cov yeeb yaj duab ntawm cov npuav, yog li cov ntawv luam tawm kuj yuav tsum tau UV varnish lug txhim khu lawv cov khoom nto. Tshaj tej ntawm, daim nplaum ntawm tus kheej daim nplaum yuav tsum tau glazed kom tau raws li lub siab gloss, matte, low coefficient ntawm kev sib txhuam los yog siab overprinting yuav tsum tau ntawm daim ntawv qhia nws tus kheej, yog li UV glazing txheej txheem yog khaws cia thiab siv. Nws tsis yog qhov nyuaj rau sawv tuaj.
Vim hais tias UV varnish tsis muaj pigments, nws muaj peev xwm tsis txhob poob lub zog ntawm UV number case thaum lub ziab vim kev nqus cov teeb ntawm lub teeb tsis muaj los ntawm ntau cov pigments, thiab nws txoj kev ziab kom qis dua. Ntxiv mus, tus yees duab rau cov kua roj hmab ntau dua hauv UVC zaus, thiab cov yam ntxwv ntawm UV number case faib rau hauv UVB thiab UVA yog qhov txawv txav. Qhov sib piv nrog cov xov tooj cua tam sim no zoo dua, thiab nws tsis yooj yim los xaiv UV teeb. Lub tswv yim ntawm flexo number case + UV varnish yog qhov ua tau zoo heev nyob rau hauv tus txheej txheem, thiab tsis xav kom txhob txwm ua zoo hloov rau cov cuab yeej thiab lub ntsiab raw raw. Qhov tseem ceeb tshaj plaws yog tias tus nqi ntawm UV varnish tsis siab, thiab tus nqi ntawm kaum ntawm ib kilogram yog pheej yig rau cov tuam txhab sau npe. Nrog rau cov cuab yeej txo kev pom zoo, tsis tu ncua cov kev luam zoo, zoo siab rau qhov chaw zoo, thiab tshawb cov tshiab rau kev siv tus kheej flexo daim ntawv, puas muaj kev sim?
