Nqaim Web Printing Surface Treatment - Cov Ntsiab Lus Tseem Ceeb rau Txhim Kho Ink Adhesion

Kev kho deg rau Narrow Web Printing: Cov txheej txheem tseem ceeb rau kev txhim kho Ink Adhesion
Cov txheej txheem kev kho mob saum npoo av yog qhov tseem ceeb rau kev ua kom tau txais qhov tshwj xeeb luam tawm zoo thiab ua haujlwm ntev hauv kev ntim khoom yooj yim, cov ntawv lo, thiab cov ntawv tshwj xeeb, raws li cov kws tshaj lij kev lag luam.
Ua kom tiav qhov zoo tshaj plaws thiab ntev ntev - qhov ntev ntawm tus number case adhesion tseem yog ib qho teeb meem loj hauv kev sib tw thiab kev ua tau zoo -tsav teb ntawm nqaim web printing. Txhawm rau kom kov yeej lub zog qis ntawm cov substrates xws li polyethylene, polypropylene, thiab lwm yam yas, cov kws tshaj lij kev lag luam niaj hnub tab tom nrhiav rau cov khoom lag luam nqaim web printing nto kho cov kev daws teeb meem. Qhov kev tshaj tawm xov xwm no tshawb txog cov thev naus laus zis uas lav cov ntawv luam tawm ntev, kev vibrancy, thiab kev ua tau zoo rau cov ntawv sau, ntim tau yooj yim, thiab cov khoom tshwj xeeb, nrog rau cov tswv yim tseem ceeb rau kev txhim kho tus cwj mem.
Rau lub vev xaib nqaim, kev kho qhov chaw zoo tsis yog ib theem ntawm cov txheej txheem; nws yog tus yuam sij rau kev vam meej luam ntawv. Nws muaj qhov cuam tshuam tam sim ntawd ntawm cov khoom zoo li, txee rov hais dua, thiab muaj txiaj ntsig zoo nrog rau cov tshuaj lom neeg thiab cov tshuaj tiv thaiv scuff.
Surface Energy lub luag haujlwm tseem ceeb hauv Ink Adhesion
Nto lub zog nyob ntawm lub plawv ntawm kev sib tw adhesion. Txij li cov ntaub ntawv polymer thiab cov yeeb yaj kiab feem ntau muaj lub zog qis, lawv tsis yog - ntxeem tau thiab muaj tshuaj lom neeg. Kev ntub dej tsis zoo yog qhov tshwm sim ntawm qhov teeb meem no, uas ua rau inks, coatings, thiab adhesives hlaws es tsis txhob sib kis thiab sib txuas. Hloov kho qhov substrate nto ntawm qib molecular thiaj li ua kom nws lub zog saum npoo thiab tsim cov chaw ua haujlwm rau kev sib cuam tshuam tshuaj lom neeg yog lub hom phiaj tseem ceeb ntawm kev kho lub vev xaib nqaim. Cov txheej txheem no yog qhov tseem ceeb rau kev tsim cov ntawv luam tawm ntawm cov yeeb yaj kiab hloov tau yooj yim thiab rau kev lees paub kev ua tau zoo ntawm tus number case.
Txoj Kev Tu Nto Tseem Ceeb rau Narrow Web Presses
Ntau yam kev siv thev naus laus zis muaj nyob rau niaj hnub nqaim web converters. Lub substrate, xovxwm configuration, ceev, thiab npaj tau tshwm sim tag nrho cov cuam tshuam cov txheej txheem xaiv.
Txoj Cai Kev Lag Luam rau Kev Kho Mob Corona
Hauv lub vev xaib nqaim, kev kho mob corona tawm tseem yog cov txheej txheem nrov tshaj plaws. Nws ua haujlwm los ntawm kev tsim lub siab -voltage hluav taws xob tawm ntawm lub hauv paus dielectric cov menyuam thiab cov electrode. Raws li qhov tshwm sim, huab cua yog ionised, ua ib lub plasma uas ntaus lub substrate nto. Ntxiv nrog rau kev tshem tawm cov kuab paug organic, qhov kev foob pob no ntxiv cov polar functional pawg-xws li hydroxyl thiab carbonyls- rau cov saw hlau polymer. Lub substrate lub zog saum npoo tau nce zoo heev los ntawm cov txheej txheem oxidation no, uas ua rau nws tus cwj mem - teb. Ntxiv rau qhov muab kev tswj hwm lub zog kom raug, cov txheej txheem kho mob corona niaj hnub no tau txais txiaj ntsig rau lawv lub peev xwm los koom ua ke hauv thiab ua haujlwm zoo nrog ntau yam khoom siv.
Plasma Therapy: Sophisticated & Yog
Txawm hais tias corona yog hom plasma atmospheric, kev hloov pauv ntau dua thiab zoo ib yam yog muab los ntawm cov cuab yeej kho ntshav tshwj xeeb (feem ntau ntawm qhov tsis tshua muaj siab lossis nrog cov roj tshwj xeeb). Cov qib siab ntawm kev ua kom nto tuaj yeem ua tiav nrog txoj kev no yam tsis muaj kev pheej hmoo ntawm kev kho mob ntau dhau, uas qee zaus tshwm sim nrog corona. Nws ua haujlwm zoo tshwj xeeb tshaj yog rau cov khoom sib txawv 3D, cov khoom siv kho mob, thiab cov ntaub ntawv uas muaj kev kub ntxhov. Plasma deg activation yog ib qho kev daws teeb meem zoo tshaj plaws rau cov teeb meem ntawm tus number case adhesion nyob rau hauv siab -kawg daim ntawv thov uas xav tau qib siab tshaj ntawm adhesion kev ntseeg siab.
Kev kho nplaim taws: ruaj khov rau cov khoom tshwj xeeb
Ib txoj kev muaj zog ntawm thermal oxidation yog kev kho cov nplaim taws. Lub vev xaib substrate taug kev hla lub txhab nyiaj hluav taws xob, qhov chaw ua tib zoo tswj cov nplaim taws hloov kho qhov chaw chemistry los ntawm kev sib txuas cov txheej txheem dawb - radical thiab cua sov. Nws ua haujlwm zoo kawg nkaus ntawm polyolefins thiab feem ntau siv rau cov yeeb yaj kiab tuab, ntim, thiab cov xwm txheej uas yuav tsum tau ua kom ntev, ntev - hloov kho qhov chaw. Nws yog ib qho tseem ceeb rau kev txhim kho tus cwj mem ua raws li cov yeeb yaj kiab yas vim nws lub peev xwm los muab qhov sib sib zog nqus thiab ruaj khov rau saum npoo.
Tshuaj ua ntej- kho thiab primer txheej
Qee lub sij hawm siv cov tshuaj primer lossis tshuaj ua ntej - kho, tshwj xeeb tshaj yog rau cov substrates uas nyuaj heev los luam tawm lossis rau cov inks tshwj xeeb (xws li inks conductive). Cov txheej txheej no muaj lub siab - lub zog, txheej txheej txheej txheej txheej txheej uas ua kom yooj yim rau tus number case anchoring. Ntawm qee qhov qis-zog polymers, qhov twg kev kho tus mob corona ncaj qha yuav tsis txaus, cov txheej txheem no yog qhov tseem ceeb rau kev txhim kho UV number case adherence.
Txhim khu kev kho rau Sustainability thiab kev ua tau zoo
Optimization yog qhov tseem ceeb ntxiv rau kev xaiv cov txheej txheem. Kev sib raug zoo tau lees paub los ntawm kev siv dyne cwjmem lossis cov neeg sim online los saib xyuas lub zog saum npoo. Cov kab ke uas muab kev ua haujlwm siab tshaj plaws- kho kom zoo ntawm cov xovxwm nrawm dua thaum siv lub zog tsawg kawg nkaus - yog qhov sib txawv ntawm kev lag luam. Tsis tas li ntawd, los ntawm kev txhim kho kev hloov pauv thiab kev pab them nqi, kev kho qhov chaw tsim nyog tuaj yeem txo qis kev siv number case thiab txhawb kev luam ntawv zoo dua qub los ntawm kev txo cov khoom pov tseg. Cov txiaj ntsig ib puag ncig thiab kev ua haujlwm ntawm cov ntawv luam tawm ncaj qha cuam tshuam los ntawm kev tsom mus rau adhesion nce qib los ntawm kev kho kom zoo.
Lub neej yav tom ntej: Intelligent Technology thiab kev koom ua ke
Smarter, ntau integrated systems yog txoj kev ntawm lub neej yav tom ntej rau nqaim web printing nto kho. Cia siab tias yuav muaj kev txhim kho ntau ntxiv hauv cov kaw lus kaw, chambered corona units uas ua rau kom muaj txiaj ntsig zoo thiab txo qis ozone ntau lawm. Kev tswj hwm kev tswj hwm kev sib koom ua ke yuav ua kom muaj kev hloov pauv hloov hluav taws xob raws li substrate thiab ceev, lav qhov kev kho zoo tshaj plaws nrog cov neeg ua haujlwm me me. Kev tsim kho tshiab yuav txhawb nqa los ntawm kev tshawb nrhiav cov tswv yim tseem ceeb ntxiv los txhim kho kev ua raws li tus lej, tshwj xeeb tshaj yog rau cov tshiab tsim bio-raws li thiab siv cov yeeb yaj kiab uas ua rau muaj teeb meem adhesion tshiab.
Hauv luv luv
Hauv kev xaus, converters siv zog rau qhov zoo tsis tuaj yeem cuam tshuam txog kev kho qhov chaw rau lub vev xaib nqaim. Cov txheej txheem no, uas muaj ntau yam los ntawm kev siv dav siv los kho corona mus rau kev ua kom cov ntshav plasma ntog, yog cov yeeb yaj kiab zais uas muab cov ntawv sau thiab ntim lawv lub sijhawm ntev - kav ntev, muaj xim zoo nkauj. Cov tshuab luam ntawv tuaj yeem daws cov teeb meem adhesion, qhib lub sijhawm thov tshiab, thiab muab lawv cov neeg siv khoom nrog cov khoom zoo - zoo, muaj kev ntseeg siab los ntawm kev nkag siab thiab ua raws li cov txheej txheem tseem ceeb rau kev txhim kho tus cwj mem. Kev nqis peev tsis tu ncua thiab kev ua tau zoo hauv kev kho saum npoo yuav ua rau muaj txiaj ntsig zoo ntawm kev sib tw hauv lub vev xaib nqaim vim cov txheej txheem hloov pauv thiab cov ntawv luam tawm yuav nyuaj dua.
