Vim li cas nws hu ua flexographic luam ntawv?

Lub npe ntawm flexography los los ntawm nws cov tub ntxhais feature - Qhov hloov pauv, uas tuaj yeem txheeb xyuas cov khoom luam ntawv, uas tau txheeb xyuas los ntawm qhov ntev:

1. Yooj ntawm Kev Luam Ntawv Cov Khoom Siv (Core Ntxhais Naming Hauv Paus)
Luam Ntawv Cov Qauv Qauv
Flexographic Printing siv daim phiaj hloov nyiaj (xws li polymer cob cov phiaj, cov phiaj roj hmab), uas feem ntau yog 1.7-7m tuab thiab tuaj yeem khoov thiab deformed.
Piv nrog tsoos letterpress luam ntawv (xws li Lead Letterpress, Hard Resin daim hlau), Flexographic Printing cov paib yog softer thiab muaj peev xwm zoo li yas hoses, hlau canks).
Kev them nyiaj ywj kho tshuab
Flexographic Printing daim phiaj yuav tuaj yeem yauv tsis muaj teeb meem kev lag luam, thiab cov khoom siv tau los nthuav tawm cov cwj pwm tuab tshiab ntawm lub substrate.
Piv txwv li: 100 kab / nti dots ntawm lub tshuab luam ntawv yuav nthuav dav rau 110 kab / nti.
2. Txhim kho embodiment ntawm cov txheej txheem cov yam ntxwv
Kev yoog tau ntawm substrates
Flexographic Printing tau sib haum nrog cov yeeb yaj kiab uas yog 0.02 hli (xws li ntim cov tshuaj ntim cov thawv ntim khoom), thiab cov ntaub ntawv ntim khoom noj (xws li cov tshuaj ntim khoom noj).
Piv nrog offset printing (xav tau high - cavance prostrates), qhov kev hloov kho siab ntawm kev luam ntawv flexographic yog qhov tseem ceeb.
Kev tswj hloov tau ntawm number case thiab siab
Ink Hom: tsuas yog siv dej - raws, siv cov viscosity nrog, haum rau nyias txheej txheej luam ntawv luam ntawv.
Siab hloov kho: los ntawm lub siab tswj ntawm anilox cov menyuam thiab cov phaj ntim thickness ntawm 0.8μm tuaj yeem ua tiav kom tsis txhob muaj excusion thiab dot deformation thiab dot deformation.
2. Piv nrog "letterpress luam ntawv"
Cov yam ntxwv flexographic luam ntawv cov khoom siv tsiaj ntawv
Luam Ntawv Phaj Khoom Siv Cov Khoom Siv Hluav Taws Xob
Siab Yuav Tsum Muaj Siab Siab (0.1-0.3MPA) Kev Siab Siab (0.3-0.5Mpa)
Siv tau cov ntawv sau, zaj duab xis, hlau, ntaub, thiab lwm yam ntaub ntawv qhia tuab, thiab lwm yam.
Kev Ntsuas Cov Ntawv Tshaj Tawm Dot Kev nthuav tawm 10% {}}}}} 15% (them nyiaj)

3. Keeb kwm thiab thev naus laus zis evolvution
Npe keeb kwm
Flexographic Printing lub tswv luam yog Aniline Printing (Aniline Printing (muaj npe), muaj npe tom qab siv Aniline Des Xim.
Tom qab xyoo 1950, nrog rau kev txhim kho ntawm cov phooj ywg inks thiab hloov tau daim phiaj, nws tau hloov npe flexography (hloov tau yooj yim ntawm lub tshuab luam ntawv.
Qhov zoo heev
Kev hloov pauv tau: Lub tshuab luam ntawv yog khoov tau thiab haum rau tsis xwm yeem lub hnab (xws li lub hnab ntim dej tsis sib xws, corrugated ntawv).
Kev tiv thaiv ib puag ncig: Niaj hnub no flexographic Printing tau siv dej {{}} banded} raws li txoj kab nrog cov qauv ntawm ntsuab luam ntawv.
Kev Ua Tau Zoo: Anilox Cov Menyuam Ink Khoom Siv Hluav Taws Xob tuaj yeem ua tiav high {}} kev nrawm tuaj yeem ncav cuag ntau dua 300m / min).
IV. Piv nrog Letterpress luam ntawv
Cov yam ntxwv flexographic luam ntawv cov khoom siv tsiaj ntawv
Cov Khoom Siv Phaj Yooj Yooj Yooj Yim Resin Phaj, Roj Hmab Phaj Zog Resin Phaj, Cov Phaj Lead
Cov kev xav tau cov siab, phaj elastic deformation nyiaj kho cov khoom siv siab, yuav tsum tau tswj hwm kom raug
Muaj feem cuam tshuam loj - ntim ntim, cov nqi muag muag, siab} precision cov ntawv thiab lwm yam khoom siv nyuaj
Nqi Tus Nqi Phaj Ua Nqi yog qhov nruab nrab, haum rau nruab nrab thiab loj} Kev tsim cov nqi me me, tab sis tsis muaj anilox roller poob
V. Xaus
Lub "hloov pauv tau" lo lus hauv FLEXOROROAD luam ntawv ncaj qha cuam tshuam qhov yooj ntawm nws cov luam ntawv. Cov yeeb yam no muab nws ua rau muaj txiaj ntsig zoo hauv cov xwm txheej hauv qab no:

Nkhaus nto moo: xws li yas hoses, hlau poom thiab lwm yam substrates
Nyias number case txheej yuav tsum tau: lub number txheej thickness (0.8- 1.7μm) yog haum rau loj-thaj tom qab xim luam ntawv.
Ib puag ncig sib xyaw: sib xyaw nrog dej -} bathed number case, nws ntsib cov khoom noj ntim cov qauv kev nyab xeeb.
Traditional letterpress printing is more suitable for high-precision dot printing (such as securities anti-counterfeiting) or thick ink layer requirements (such as UV glazing) due to the high hardness of the printing plate. Ob lub tshuab thev naus laus zis txuam nrog lwm tus, thiab cov tuam txhab yuav tsum tau xaiv cov kev xaiv raws li kev siv tshuab luam ntawv, batch loj, nqi, thiab lwm yam.
