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 sau nqi chaw ntawm daim ntawv lo, thiab vim tus UV number case nws tus kheej muaj kev tsim thiab ib puag ncig tsis muaj teeb meem, nws pib nrog txoj kev hloov kho, thiab ntau xyoo cov tshuaj UV nrog ink printing + UV txheej . 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 cov yeeb yam sib txawv ntawm lawv cov khoom nrog rau zaj duab xis, thiab yuav tsum nruj nruj tswj hwm cov teeb meem ntawm cov dej thiab cov yeeb yaj kiab, uas yog, cov kabmob zoo sib xws, cov kev tsis sib haum xeeb yog cov zoo sib xws, thiab cov kev sib ntxiv ntawm hydrogen tshiab yuav tsum generated. Cov tuam txhab luam ntawv yuav tsum tau siv cov kev ua sim los soj ntsuam, xaiv thiab ntsuam xyuas tawm ntawm tus cwj pwm uas tsim nyog, xyuam xim tsis yoojyim veto, dump tag nrho cov phim uas tseem tsis sib thooj, tab sis tsis txhob blindly ntsuam xyuas lub tshuab, nce tus nqi kuaj.
2. Tshem tawm ntawm zaj yeeb yaj kiab
Qhov tseem ceeb ntawm kev ziab khaub zig rau hauv zaj duab xis yog kev tsis txaus siab, thiab ziab yog txhais tau hais tias lub ntsiab lus tseem ceeb. 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 kev kub ntxhov, tso dej khiav tawm; tom qab ntawd ces qhov ze ntawm cov nplaim phom molecules, dej ntub dej; thiab thaum kawg lub pob cwj pwm los ntawm kev sib koom tes (nrog rau kev sib koom tes sib txuas hauv kev sib koom tes).
Ib qho ntawm cov lus sib txawv yog tib yam, uas yog, cov tshooj qhuav qhuav yog volatilized, tsis muaj lwm txoj hau 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. Yog li, nws tseem zoo los txiav txim seb tus dryness ntawm tus number case saum npoo los ntawm kev siv lub ntsuas phom finest los txiav txim siab lub sijhawm ntev ntawm tus number case. Hom no tuaj yeem paub ceev ceev ntawm tus number case ziab zis ua ntej lub tshuab nyob rau, thiab txiav txim tau qhov tsis ua tiav ntawm lub tshuab luam ntawv. Npaum li cas.
3. Lub caij nplooj ntoos zeeg nthuav tawm hauv kev luam ntawv
Qhov txawv ntawm qhov sau rau ntawm daim duab saum toj no yog dab tsi? Nyob hauv qhov tseeb, tus lej ntawm tus cwj mem qhuav, tus xauv npog ntawm tus number case thiab tus UV number case tsis yog nyob rau ib theem, thiab qhov txawv ntawm ob yog 1 mus rau 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? Txij li thaum siv lub tshuab xauv nrog qhov khoob khov mis khov (raws li pom hauv daim duab hauv qab no), yog tias siv lub khoob khoob loj nrog cov kws kho hniav kaw, lub vev xaim-siab khov tsis tuaj yeem siv tsis tau. 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, puas muaj cov cwj mem uas tsis saib xyuas thiab kho tus pH thaum lub sij hawm luam ntawv? Cov lus teb yog muaj, tab sis koj yuav tsum kawm kom ntsuam xyuas ntau ntawm tus cwj mem. Hauv kev luam cov txheej txheem, lub ntsiab tseem ceeb rau lub fluctuation ntawm tus nqi pH ntawm tus cwj pwm yog cov evaporation ntawm ammonia ua stabilizer, thiab evaporation ntawm ammonia yog qhov ua rau muaj kev hloov hauv pH 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 cov tuam txhab luam ntawv, yuav kom 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 ntus mus rau lub sijhawm, qhov tseem ceeb nyob hauv kev ntsuam xyuas ntawm number case, tshwj xeeb tshaj yog kuaj 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 tawv nqaij ntawm nws tus kheej-adhesive daim ntawv yog thawj tsim nyog yuav tsum tau glazed kom tau raws li lub siab gloss, matte, tsawg coefficient ntawm kev sib txhuam los yog siab overprinting yuav tsum tau ntawm daim ntawv qhia nws tus kheej, yog li ntawd tus thawj 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 yuav tsis txhob poob lub zog ntawm UV number case nyob rau hauv cov txheej txheem so vim ntawm cov yam ntxwv ntawm lub teeb ntawm lub teeb tsis pom los ntawm ntau cov pigments, thiab nws txoj kev ziab kom qis. Ntxiv mus, tus yees duab rau cov kua roj hmab ntau dua hauv UVC zaus zaus, thiab cov yam ntxwv ntawm UV number case thiab UVA tis yog 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?
