Matte UV Flexo Ink
Matte UV Flexo Ink yog UV-kho tau flexographic number case tsim los tsim qhov qis-gloss nto (feem ntau 5-20 GU ntawm 60℃kaum sab xis) ntawm cov tsis yog -absorbent substrates. Cov nyhuv matte yog tsim los ntawm kev tswj hwm micro- cov qauv ntxhib saum npoo tsim thaum lub sijhawm kho, feem ntau ua tiav los ntawm kev sib xyaw cov tshuaj matting xws li silica hais (2-6 µm) lossis los ntawm kev siv theem- cais oligomer systems.

Khoom Taw qhia
Composition thiab Formulation Structure
Oligomers (30-50%)
Feem ntau urethane acrylates los yog polyester acrylates. Cov no txiav txim siab ua kom yooj yim thiab adhesion. Urethane systems feem ntau raug xaiv rau kev siv zaj duab xis vim lawv cov khoom elongation.
Reactive Monomers (20-40%)
Tsawg- ntxhiab monomers xws li IBOA lossis TPGDA yog siv los tswj cov viscosity (200–800 mPa·s) thiab txo cov emissions volatile.
Photoinitiators (5-10%)
Tsawg tsiv teb tsaws / ntxhiab hom, nrog qhov nqus siab tshaj plaws sib tw rau 365-395 nm UV teeb kom sib npaug ntawm kev kho ceev thiab kev pheej hmoo ntawm kev tsiv teb tsaws.
Pigments (10-20%)
Organic los yog inorganic pigments (< 1 µm) to ensure stable dispersion and consistent color density in flexo plates.
Matte UV flexo number case yog siv raukho tsis yog - ntxeem tau substrates, qhov twg lub zog saum npoo yuav tsum tau tswj:
BOPP zaj duab xis: Ntau dua los yog sib npaug rau 38 dyn / cm (Corona kho)
PET zaj duab xis: Ntau dua los yog sib npaug rau 40 dyn / cm rau ruaj khov adhesion
PE zaj duab xis: often requires primer or higher treatment (>42 hli / cm3)
Paperboard: cov qib coated pub kom zoo matte uniformity tshaj qhov chaw tsis muaj coated
Tsawg zog nto (<36 dyn/cm) can cause uneven ink distribution, leading to inconsistent gloss and patchy matte areas.
Cov txheej txheem luam ntawv muaj
Label Printing (siab-Sensitive Labels)
Anilox:400-500 PIB, ntim 2.5-3.5 cm³ / m²
Printing ceev:80-150m / min
UV teeb:120-160 W / cm
Hauv kev tsim cov ntawv lo, matte number case feem ntau yog siv los ua ib qhosab saum toj txheejlos tsim kev sib piv nrog gloss varnishes. Kev tso npe kam rau ua yuav tsum tau tswj nyob rau hauv± 0.1 hliua kom pom kev sib xws.
Flexible Ntim (Laminated Films)
Ink siv rauthim rov qab txheej txheej luam ntawvlos yog nto luam tawm nyob ntawm tus tsim
Lamination tau ua tom qab kho, nrog cov nplaum txheej hnyav2–3 g/m²
Matte nto tuaj yeem cuam tshuam rau lamination daim ntawv cog lus vim txo qhov chaw sib cuag, yog li kev xaiv nplaum thiab siab (2-4 bar nip siab) yuav tsum tau kho.
Carton thiab Folding Box Printing
Substrate: coated paperboard (200-350gsm)
Ink coverage: cov khoom siv los yog xaiv matte tiav
Nyob rau hauv lub thawv luam ntawv, matte number case txo glare hauv khw muag khoom teeb pom kev zoo (feem ntau500-1000 lux), txhim kho kev nyeem ntawv ntawm cov ntawv luam tawm.

FAQ:
Vim li cas cov nyhuv matte ua tsis sib xws thaum luam ntawv?
Qhov tsis sib xws matte zoo li feem ntau yog tshwm sim los ntawm kev hloov pauv tus cwj mem tsis sib xws los yog qhov sib txawv ntawm lub zog substrate:
Anilox hnav lossis kis kab mob hloov pauv tus lej ntim khoom xa tuaj (± 0.5 cm³ / m² hloov pauv tuaj yeem cuam tshuam gloss)
Kev kho substrate qis dua 38 dyn / cm ua rau cov dej ntub dej tsis zoo thiab qhov chaw nyob ib puag ncig
Ink viscosity drifting sab nraum 300-900 mPa·s hloov tus cwj pwm ntws
Cov xwm txheej no ua rau pom pom qhov sib txawv ntawm qhov chaw luam tawm.
Kev kho lub zog cuam tshuam li cas rau kev ua haujlwm matte?
Curing zog ncaj qha cuam tshuam cov qauv tsim:
Ntawm 120–150 mJ / cm², ceev crosslinking xauv hauv micro-roughness → qis gloss
Tshaj 180-200 mJ / cm², ntau dhau lawm tshwm sim ua ntej kho → smoother nto → gloss nce
Kev siv lub teeb yuav tsum tau saib xyuas kom nyob tsis pub dhau 80-100% ntawm cov khoom siv ntsuas kom tswj tau qhov sib xws.
