Scratch Resistant UV Flexo Ink
Scratch-Resistant UV Flexo Ink yog qhov tseem ceeb ntawm UV-kho tus cwj mem uas tuaj yeem txhim kho kev puas tsuaj los ntawm kev nce kev sib txuas ceev thiab qhov tawv tawv.

Txoj Cai Ua Haujlwm
Kev kho ntawm UV flexographic inks yog qhov tseem ceeb ntawm cov dawb radical - pib photopolymerization cov tshuaj tiv thaiv:
Thaum UV teeb irradiation, photoinitiator decomposes los tsim cov dawb radicals. Cov dawb radicals no pib ua cov tshuaj tiv thaiv ntawm acrylate monomers thiab oligomers, tsim ib qho peb -siv qhov sib txuas sib txuas.
Lub hauv paus ntawm khawb kuj yog nyob rau hauv:
1. Ua kom Crosslink ceev
Siv siab -functionality oligomers (xws li trifunctional lossis multifunctional polyurethane acrylates)
Txhim kho qhov ceev ntawm lub network qauv
👉 Qhov tshwm sim: Ib qho tawv tawv, txhim kho khawb tsis kam
2. Nto Zog thiab Slip Control
Ntxiv cov waxes tshwj xeeb lossis cov khoom ntxiv (xws li PTFE lossis silicones)
Txo cov coefficient ntawm kev sib txhuam
👉 Qhov tshwm sim: Txo qhov kev puas tsuaj los ntawm khawb
3. Zaj duab xis qauv Uniformity
Ink leveling txiav txim siab qhov smoothness. Ib lub ntsej muag zoo sib xws ua rau muaj kev ruaj khov dua khawb tsis kam.

FAQ:
Yuav ua li cas los txiav txim qhov "scratch resistance" ntawm khawb-resistant UV flexographic inks?
Hauv kev tsim khoom tiag tiag, ib qho qauv tsis tshua muaj siv. Hloov chaw, ntawm - txoj hauv kev sim qhov chaw tau ua haujlwm:
Los ntawm txhais tes rubbing (sab rov qab thiab rov qab nrog ib daim ntaub qhuav / ntawv phuam)
Luas test
Rubbing tester (teeb tus naj npawb ntawm cov voj voog thiab siab)
Qhov tseem ceeb tsis yog "txawm tias muaj khawb," tab sis yog:
👉 Txawm tias nws cuam tshuam rau qhov tsos lossis xim fading raws li kev thauj mus los thiab kev ua haujlwm.
Cov neeg siv khoom sib txawv muaj cov qauv sib txawv, yog li kev ntsuas kev kho mob feem ntau xav tau rau txhua daim ntawv thov.
Vim li cas qhov chaw tseem yooj yim khawb tom qab UV kho, txawm tias nws nyuaj heev?
Qhov no yog ib qho teeb meem tshwm sim, thiab feem ntau muaj peb qhov laj thawj:
Surface hardness ≠ Ua kom tiav tag nrho kev kho
Surface curing ua ntej, tab sis tsis txaus sab hauv ntoo khaub lig- txuas
Qhov tseeb abrasion kuj tseem tsis zoo
Ink txheej yog tuab heev
Kev nkag mus rau UV tsis txaus
Incomplete puab txheej curing
Tsis txaus smoothness
High coefficient ntawm kev sib txhuam
Ntau zaus rau khawb
👉 Xaus: Kos kuj tsis yog hais txog kev nce hardness, tab sis hais txog kev kho qhov tob + tus qauv saum npoo + kev sib npaug
