UV Flexo Ink Ua Haujlwm li cas hauv Folding Carton Production

Nyob rau hauv ib lub flexographic folding thawv xovxwm, tus number case hloov raws li ib tug taag mechanical sequence.

Txheej txheem luam ntawv:

Ink nkag mus rau chamber kws kho mob hniav system

Tus kws kho mob hniav ntsuas number case ntim ntawm anilox cov menyuam

Anilox hloov cov tswj tus lej ntim rau photopolymer phaj

Phaj cylinder hloov cov duab mus rau hauv lub thawv ntawv

UV teeb kho cov ntawv luam tawm zaj duab xis tam sim ntawd

Printed board txuas ntxiv mus rau hauv tuag txiav los yog hloov seem

Cov yeeb yaj kiab kho tau yog tsim los ntawm photopolymerization.

UV lub teeb ua kom cov photoinitiators hauv tus number case thiab hloov cov kua resin rau hauv cov yeeb yaj kiab.

Zaj movie no yuav tsum:

Bond rau coated los yog uncoated carton board

Tiv thaiv rubbing thaum lub thawv stacking

Flex thaum folding

Nyob ruaj khov thaum gluing thiab downstream tuav

1. Kuv yuav xaiv UV flexo number case rau coated vs uncoated folding carton board li cas?

Lub substrate nto txiav txim siab number case wetting thiab adhesion.

Rau coated SBS los yog C1S board, tus number case xav tau kev tswj qhov chaw ntub dej thiab ruaj khov hloov ntawm cov txheej coated du. Ink viscosity thiab anilox ntim feem ntau xav tau kev tswj nruj dua vim tias cov txheej nqus cov kua dej tsawg heev.

Rau uncoated kraft los yog recycled board, qhov saum npoo yog ntau ntxeem tau thiab ntxhib. Kev hloov tus cwj mem feem ntau xav tau cov xim xim muaj zog dua thiab ua tib zoo saib xyuas lub rooj tsavxwm absorbency.

Ua ntej ntau lawm, converters feem ntau txheeb xyuas:

board txheej hom
lub zog nto
anilox cell ntim
cross hatch adhesion tom qab kho
rub tsis kam tom qab tuag txiav

Cov txheej txheem sib txawv tuaj yeem xav tau sib txawv adhesion txhawb nqa.
