Digital Printing Corona Treaters: Ua cov ntawv luam tawm zoo dua ntawm cov khoom siv hluav taws xob kom qhib tau qhov tshiab
Nyob rau hauv lub ntiaj teb ceev ceev -paced ntawm digital printing, tau zoo meej, ntev - cov txiaj ntsig tau ntev ntawm cov ntaub ntawv tsis yog - ntxeem tau tseem yog qhov teeb meem loj. Cov khoom siv hluavtaws xws li polypropylene, polyethylene, PET, thiab cov ntawv coated yog tsim nyog los ua cov ntim ci, cov ntawv, thiab cov khoom txhawb nqa, txawm li cas los xij lawv lub zog qis qis qee zaum ua rau tus cwj mem tsis lo, ua rau nws tawg thiab tev. Advanced Digital Printing Corona Treaters tab tom hloov cov txheej txheem no kom zoo dua niaj hnub no. Lawv yog ib qho tseem ceeb ntawm - xovxwm kev daws teeb meem rau kev txhim kho cov ntawv luam tawm ntawm cov khoom hluavtaws. Cov thev naus laus zis no tau dhau los ua qhov yuav tsum tau ua sai sai - muaj rau cov tshuab luam ntawv thiab cov hloov pauv uas xav txhim kho lawv cov kev txawj ntse thiab ua kom lawv cov khoom siv tau ntev dua.
Qhov Adhesion Challenge: Vim li cas Cov Inks Tsis Lo rau Synthetic Substrates
Qhov teeb meem tseem ceeb yog nrog rau qhov chaw chemistry ntawm hluavtaws substrates. Cov ntaub ntawv no yog tsim los ua kom tsis muaj zog, tiv taus ya raws, thiab ntev - kav ntev. Cov no yog tag nrho cov yam ntxwv uas ib txwm tso dej tawm-raws li, UV- kho tau, thiab hnyav-raws li inks siv hauv digital printing. Yog tias koj tsis npaj qhov chaw kom zoo, tus number case yuav zaum saum cov khoom es tsis txhob sib txuas nrog nws. Qhov no yuav tshwm sim:
- Tsis tiv taus khawb thiab rub
- Xim ci ntsa iab uas tsis zoo ib yam
- Cov khaubncaws sab nraud povtseg
- Teeb meem nrog kev tshaj tawm - kev luam ntawv zoo li txheej los yog laminating
Priming thiab nplaim taws kho yog ob qho piv txwv ntawm cov txheej txheem ib txwm siv uas feem ntau xav tau ntau kauj ruam, raug nqi ntau dua, thiab tsis zoo rau ib puag ncig. Kev lag luam xav tau kev daws teeb meem sai, yooj yim siv, thiab tuaj yeem tswj tau.
Yuav ua li cas Corona Treatment Technology hloov Surface Energy
Siv lub siab -voltage hluav taws xob tawm (corona) ntawm atmospheric siab, corona cov cuab yeej kho mob daws qhov teeb meem no lub taub hau-rau. Thaum cov hluavtaws substrate mus los ntawm qhov chaw kho mob, qhov paug tawm no ua rau lub plasma teb.
Science of Better Adhesion
Muaj ob txoj hauv kev tseem ceeb uas cov plasma no cuam tshuam nrog cov khoom siv:
1. Surface Activation: Lub zog cuam tshuam cov molecular bonds nyob rau sab saum toj txheej ntawm substrate, ua rau cov chaw uas muaj reactive heev.
2. Oxidation: Nws ua rau nws yooj yim dua rau cov pa oxygen los ntawm huab cua los lo rau saum npoo, uas tsim cov tshuaj polar pawg xws li carbonyls thiab hydroxyl.
Qhov kev sib xyaw ua ke no ua rau cov khoom siv lub zog saum npoo av, ua rau nws yooj yim dua rau inks, coatings, thiab adhesives lo rau nws. Qhov no ua rau muaj kev hloov pauv ntawm qib molecular uas ua kom cov kua inks kis tau zoo sib xws thiab tsim cov khoom siv hluav taws xob thiab tshuaj lom neeg muaj zog thaum lawv qhuav.
Ntxiv Corona Cov Kws Kho Mob rau cov txheej txheem luam tawm digital niaj hnub
Lub zog tiag tiag ntawm cov tshuab luam ntawv digital corona tam sim no yog lawv ua haujlwm ua ke zoo npaum li cas. Lawv tuaj yeem siv inline nrog cov xovxwm digital los ntawm sab saum toj OEMs lossis ua cov khoom rov qab. Lawv muab:
Rau kev thov kev thov, qhov tseeb, kev tswj hwm, thiab kev sib xws yog qhov tseem ceeb.
Tam sim ntawd, Ntawm -Kev Thov Kev Kho Mob: Tsis tas yuav muaj qhov sib cais ua ntej- kev kho mob theem, uas ua rau kom ntau lawm thiab txuag chaw hauv pem teb.
Cov neeg ua haujlwm tuaj yeem siv tau yooj yim -rau- siv digital interfaces kom zoo - kho theem kho ( ntsuas hauv dynes / cm²) rau cov substrates thiab number case sib txawv. Qhov no ua kom paub tseeb tias cov ntawv luam tawm zoo yam tsis muaj kev puas tsuaj rau cov yeeb yaj kiab.
Qhov tseem ceeb rau Cov Lag Luam Tseem Ceeb: Cov qib no yog qhov tseem ceeb heev rau kev ua haujlwm siab - siv nrog rau kev luam ntawv ntim tau yooj yim, ua rau siab - siab zoo- cov ntawv rhiab heev, thiab ua cov decals uas tuaj yeem ua rau cov xwm txheej nyuaj.
Tsis yog adhesion xwb: qhov cuam tshuam loj dua ntawm kev luam ntawv zoo thiab ib puag ncig
Kev yuav ib qho kev kho mob corona cais rau kev luam ntawv digital muaj ntau cov txiaj ntsig uas dhau mus dhau los ua cov khoom ua ke.
Txhim kho qhov zoo ntawm cov ntawv luam tawm thiab kev ua haujlwm zoo
Bright Colour Gamut: Cov cwj mem zoo dua thiab kev sib txuas ua rau cov dots ntse dua, cov xim sib sib zog nqus, thiab ntau yam xim uas tuaj yeem ua tiav.
Tsawg pov tseg: Txhim kho qhov teeb meem uas ua rau muaj teeb meem adhesion txo qis ntawm kev luam tawm thiab cov ntaub ntawv pov tseg los ntawm ntau, uas ua rau cov cuab yeej siv tau zoo (OEE).
Txheej Txheem Flexibility: Cov tshuab luam ntawv tuaj yeem siv ntau txoj kev xaiv ntawm cov khoom siv hluav taws xob pheej yig thiab sim tawm cov ntaub ntawv tshiab, muaj tswv yim yam tsis muaj kev txhawj xeeb.
Pab txhawb eco-kev luam ntawv zoo
Kev tshem tawm ntawm Primers: Corona cov kws kho mob feem ntau ua rau nws tuaj yeem luam tawm ncaj qha rau ntawm qhov chaw, uas txhais tau hais tias cov kuab tshuaj-raws li primer tsho tiv no tsis xav tau lawm. Qhov no txo qis VOC emissions thiab ua rau cov txheej txheem ntau lawm yooj yim dua.
Cov Khoom Siv Ua Haujlwm: Kev ua kom muaj zog tuaj yeem tso cai rau koj siv cov number case tsawg dua los yog cov ntaub ntawv nyias nyias uas tsis ua rau cov khoom tsis ruaj, uas yuav pab txuag tau cov peev txheej.
Lub neej yav tom ntej yog kho: Cov ntsiab lus ntawm kev nqis peev zoo
Kev kho deg tau ploj mus los ntawm qhov kev xaiv ntxiv rau cov kev daws teeb meem tseem ceeb rau kev luam ntawv zoo dua vim tias cov hom lag luam thiab cov neeg siv khoom xav kom luam tawm ntev dua thiab zoo dua rau txhua yam los ntawm eco- cov yeeb yaj kiab hloov tau yooj yim rau cov ntawv sau. Cov tshuab luam ntawv digital corona tsis yog rau ib pawg neeg tsawg xwb; lawv yog cov peev txheej ntse rau txhua qhov kev pabcuam luam tawm uas xav tau ua ntej ntawm qhov kev ua si.
Lawv tsuas muaj kev vam khom, kev tshawb fawb - txoj kev pov thawj los txhim kho kev sau ntawv ntawm cov khoom siv hluavtaws. Qhov no qhib qhov kev cia siab rau kev lag luam tshiab, tiv thaiv kev ncaj ncees ntawm cov khoom lag luam los ntawm kev ua cov khoom lag luam ntev dua, thiab npaj cov haujlwm rau kev hloov pauv kev xav tau ntawm kev lag luam. Yog tias cov tshuab luam ntawv xav tau qhov zoo tshaj plaws hauv kev ua tau zoo, hloov tau, thiab ua haujlwm tau zoo, lawv yuav tsum siv cov thev naus laus zis no.
