Tsis tshua muaj ntxhiab UV Flexo Ink
Tsis tshua muaj ntxhiab UV Flexo Ink yog UV- kho tau flexographic luam ntawv number case formulated nrog qis-volatility monomers thiab tswj photoinitiator systems kom txo cov ntxhiab tsw qab tom qab kho.

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.
Nws ua haujlwm li cas (Curing Mechanism)
UV teeb emit zog nyob rau hauv 300-400 nm ntau yam.
Photoinitiators nqus lub zog no thiab tsim cov radicals.
Radicals pib crosslinking ntawm oligomers thiab monomers.
Cov ntaub ntawv polymer cov ntaub ntawv hauv 0.1-0.3 vib nas this hauv qab 120-200 mJ / cm² UV koob.
Kev ua haujlwm tsis tshua muaj ntxhiab yog ua tiav los ntawm kev txwv cov monomers tsis muaj kev cuam tshuam thiab xaiv cov khoom siv raw nrog qis volatility.

FAQ:
1: Dab tsi ua rau tsw hauv UV flexo inks tom qab kho?
Cov ntxhiab tsw seem feem ntau yog los ntawm cov monomers unreacted thiab photoinitiator fragments tshuav nyob rau hauv tus cwj mem zaj duab xis tom qab UV curing. Yog hais tias lub zog curing qis dua 120 mJ / cm² los yog txheej number case ntau tshaj 3 g / m², tsis tiav polymerization tuaj yeem tshwm sim, ua kom tsw tsw. Kev xaiv ntawm siab -volatility monomers kuj tseem ua rau kev tshaj tawm - luam tawm tsw.
2: Yuav ua li cas tsw yuav txo tau thaum lub sij hawm luam ntawv?
Cov ntxhiab tuaj yeem tswj tau los ntawm kev kho peb qhov tseem ceeb:
Nce UV koob rau 150-200 mJ / cm² los txhim kho kev ua kom tiav
Txo tus number case zaj duab xis thickness los ntawm xaiv ib tug qis ntim anilox roller (piv txwv li . 2.5–3.0 cm³/m²)
Tuav lub zog substrate saum npoo saum npoo ntawm 38 dyn / cm kom paub meej tias tus number case hloov tau zoo thiab ua kom zoo
Kev kho tsis txaus lossis tsis sib xws ntawm tus number case laydown yuav ua rau kom cov ntxhiab tsw seem.
3: Puas yog tsw ntxhiab UV flexo number case haum rau ntim khoom noj?
Nws feem ntau yog siv rau txheej txheej ntim khoom noj, xws li cov hnab khoom noj txom ncauj lossis cov ntawv haus dej haus, qhov twg tus number case tsis nyob rau hauv kev sib cuag nrog zaub mov. Rau cov ntawv thov no, txo cov ntxhiab tsw yog qhov tseem ceeb los tiv thaiv kev hnov mob thaum lub sijhawm khaws cia. Rau kev sib cuag zaub mov ncaj lossis tsis ncaj, kev ua raws cai ntxiv (xws li kev txwv kev tsiv teb tsaws chaw) yuav tsum tau txheeb xyuas nyias.
