Central Drum CI flexographic luam ntawv xovxwm yog qhov kev xaiv zoo tshaj plaws rau nonwovens thiab ntawv luam ntawv vim lawv qhov siab precision, efficiency, thiab ruaj khov. Lawv qhov tshwj xeeb sib koom ua ke lub tog raj kheej tsim kom ntseeg tau zoo rau kev sau npe raug, ua rau lawv tshwj xeeb tshaj yog haum rau ntau-xim, siab - ntim ntau lawm. Txawm li cas los xij, kev ua tiav cov txiaj ntsig zoo luam ntawv ntawm ob lub substrates nrog cov yam ntxwv sib txawv yuav tsum muaj kev nkag siab tob txog lawv cov khoom thiab kev tswj xyuas meej ntawm txhua kauj ruam ntawm cov txheej txheem luam ntawv.
1. Substrate yam ntxwv: Kev paub yog lub hauv paus ntawm kev vam meej.
Nonwovens: Lawv feem ntau muaj qhov ntxeem tau thiab tsis sib xws, ua rau muaj zog number case absorption tab sis nws yuav ua rau muaj qhov nce. Lawv elasticity ua rau lawv raug rau stretching nyob rau hauv printing nro, cuam tshuam rau kev sau npe. Lawv qhov tsis tshua muaj zog saum npoo ua rau lawv raug rau linting thiab pilling.
Daim ntawv: Nto smoothness txawv heev (los ntawm ntxhib kraft mus rau du coated ntawv), ncaj qha cuam tshuam rau dot reproduction. Lawv cov cwj mem nqus thiab lub zog saum npoo yuav tsum tau muab sib npaug rau tus cwj mem kom tsis txhob luam tawm - los ntawm thiab xaiv plaub hau.
2.Precision Prepress Matching: Tso lub hauv paus rau kev vam meej
- Printing Phaj Xaiv: Lub hardness ntawm cov ntawv luam ntawv siv nyob rau hauv CI flexographic luam ntawv xovxwm yuav tsum tau sib phim rau cov khoom. Thaum luam ntawv nonwovens, softer daim hlau feem ntau yog siv los kho kom zoo dua rau lawv qhov ntxhib saum npoo thiab xyuas kom txaus tus number case hloov. Thaum luam ntawv daim ntawv du, me ntsis nyuaj daim hlau yuav siv tau kom ua tiav cov dots sharper.
- Anilox Roller Pairing: Qhov no yog qhov tseem ceeb rau kev tswj tus number case ntim. Nonwovens, vim lawv cov number case nqus nqus, feem ntau xav tau ntau dua number case loading peev, yog li anilox rollers nrog qis xov suav thiab ntau tus number case muaj peev xwm xaiv tau. Thaum luam ntawv siab - ntawv zoo, anilox rollers nrog cov xov ntau dua thiab cov peev txheej me me yuav tsum tau ua kom rov tsim cov dots zoo.3. Precision Process Control: Peb Cov Ntsiab Lus
Kev Tswj Kev Nyuaj Siab: Cov kev tswj nruj ntawm lub hauv paus nruas flexo tshuab luam ntawv yog lub neej ntawm cov txheej txheem. Nonwovens yog heev elastic. Kev nro ntau dhau tuaj yeem ua rau ncab thiab deformation, ua rau kev sau npe tsis raug; tsis txaus nro yuav ua rau wrinkling. Daim ntawv nruj yuav tsum tau teem raws li nws qhov hnyav thiab lub zog kom tsis txhob tawg lossis sagging. Kev tuav ruaj khov thiab sib npaug nro thoob plaws tag nrho cov kab luam ntawv yog qhov tseem ceeb.
Kev kho siab:
- Inking Pressure (Anilox Cov Menyuam thiab Phaj Cov Menyuam): Kev sib cuag maj mam yog txaus los xyuas kom meej tias txawm tias hloov tus number case rau lub phaj luam ntawv.
- Printing Pressure (Plate Roller and Impression Roller): Lub ntsiab lus ntawm flexographic luam ntawv tshuab ua haujlwm yog "siab tsawg kawg nkaus rau kev pom zoo." Kev siab dhau heev tuaj yeem ua rau muaj qhov loj me me thiab smearing, tshwj xeeb tshaj yog rau cov khoom siv tsis-woven; tsis txaus siab yuav ua rau whiteouts thiab smudged print.
Video Taw Qhia
Ink thiab Drying: CI flexographic luam ntawv xovxwm suav nrog cov tshuab ziab kom zoo. Vim qhov kev nkag mus sai sai kom qhuav cov yam ntxwv ntawm cov khoom siv tsis yog, cov xovxwm qhov cub yuav tsum tau teem kom zoo kom tsis txhob overdrying saum npoo. Rau daim ntawv, gradient kom qhuav yog yuav tsum tau ua kom huv si ntawm tus number case txheej. Lub tshuab number case yuav tsum muaj qhov ruaj khov viscosity thiab pH, uas yog qhov tseem ceeb rau cov xim sib xws.
4.Tom qab luam ntawv, lub anilox roller, phaj, thiab number case tank yuav tsum tau muab ntxuav kom huv si tam sim ntawd kom tsis txhob muaj dej -raws li number case los ntawm ziab tawm thiab txhaws cov hlwb. Qhov no yog lub hauv paus ntawm lub sijhawm ntev -, ruaj khov luam ntawv zoo.
Hauv cov ntsiab lus, kev paub txog kev kos duab ntawm lub hauv paus nruas flexo luam ntawv xovxwm rau nonwovens thiab ntawv yog txheej txheem txheej txheem uas pib nrog kev nkag siab cov ntaub ntawv thiab txuas ntxiv los ntawm kev sib tw ua ntej, txheej txheem zoo -tuning, thiab post- xovxwm tu. Tsuas yog los ntawm kev hwm qhov xwm txheej ntawm cov khoom siv thiab coj los ntawm cov ntaub ntawv thiab kev paub dhau los tuaj yeem tsim cov khoom tsis zoo nrog cov xim zoo nkauj thiab ruaj khov zoo hauv ob qhov kev thov dav dav, yog li tau txais txiaj ntsig kev lag luam tseem ceeb.
