Corona Tshuab rau Laminated Printing - Yuav Ua Li Cas Txhim Kho Cov Khoom Ntawm Laminates

Hauv kev sib tw heev ntawm kev ntim khoom yooj yim thiab cov ntawv luam tawm laminates, ua kom muaj qhov tshwj xeeb thaiv kev tiv thaiv kev ya raws, oxygen, thiab ntxhiab tsw yog qhov tseem ceeb. Txawm hais tias kev xaiv cov khoom siv yog qhov tseem ceeb, feem ntau saib tsis tau tseem ceeb hauv cov txheej txheem no yog cov khoom siv kho mob corona siv rau laminated luam ntawv. Qhov tseem ceeb ua ntej -kev kho technology no ua rau muaj kev txhim kho cov txheej txheem ntawm laminates, ncaj qha cuam tshuam rau lawv cov kav ntev, kev ncaj ncees, thiab cov khoom thaiv. Los ntawm kev hloov lub zog saum npoo ntawm substrates, kev kho mob corona tau lees paub qhov zoo tshaj plaws adhesion ntawm cov khaubncaws sab nraud povtseg tom ntej -xws li dyes, adhesives, thiab coatings- ua ib qho seamless thiab impervious barrier.
Cov Ntsiab Cai ntawm Kev Tshawb Fawb ntawm Nto Ua Haujlwm
Kev kho mob corona rau laminated luam ntawv ua haujlwm raws li lub hauv paus ntsiab lus ntawm atmospheric plasma paug. Raws li cov yas zaj duab xis (xws li PP, PE, PET, lossis metallised substrates) nce mus los ntawm lub tshuab, lub siab -voltage electrode ionises cov huab cua puag ncig. Qhov no ua rau muaj kev tswj hwm "corona" tso tawm ntawm cov ntshav plasma, nthuav tawm cov duab ntawm cov yeeb yaj kiab kom muaj zog ions, electrons, thiab dawb radicals.
Qhov kev foob pob tawg no cuam tshuam cov saw hlau molecular ntawm lub ntsej muag polymer, uas ua rau muaj kev ua haujlwm ntawm cov polar pawg xws li carbonyls thiab hydroxyl. Qhov tshwm sim yog qhov nce siab hauv lub zog saum npoo ntawm cov khoom, qhia hauv dynes ib centimeter. Lub zog saum npoo siab dua hloov pauv qhov qub inert, tsis yog - nplaum, thiab qis- lub zog nto rau hauv qhov chaw txais, siab - lub zog, npaj rau kev ua kom zoo.
Kev koom ua ke hauv Lamination thiab Printing txheej txheem
Feem ntau muab tso rau hauv kab ua ntej luam ntawv, txheej, los yog laminating chaw nres tsheb, tus kws kho mob corona rau cov ntim ntim tau yooj yim lav tias lub substrate tau npaj tau zoo thaum lub sijhawm nws tau txais tus cwj mem lossis nplaum. Qhov kev sib koom ua ke tsis muaj seamless no yog qhov tseem ceeb rau kev txhawb nqa kev tsim khoom thaum ua kom muaj kev sib raug zoo, siab - kev txhim kho laminate zoo.
Yuav Ua Li Cas Kho Corona Tam Sim No Txhim Kho Cov Khoom Muaj Teeb Meem
Tsim kom muaj kev sib txuas tsis zoo: Lub hauv paus ntawm Barrier Integrity
Qhov laj thawj tseem ceeb ntawm kev ua tsis tiav hauv cov teeb meem laminate feem ntau cuam tshuam ntawm qhov sib cuam tshuam ntawm cov khaubncaws sab nraud povtseg - qhov twg tus number case yuav detach los yog nplaum yuav delaminate. Daim ntawv cog lus tsis yooj yim pab txhawb kev tsim cov micro-channels uas tso cai rau kev xa cov pa roj thiab vapors. Corona nto kho kom txo tau qhov kev pheej hmoo no los ntawm kev ua kom muaj kev nthuav dav, molecular- qib adhesion ntawm cov nplaum thiab cov substrate. Qhov kev sib xyaw ua ke no tshem tawm txhua qhov tsis zoo, tsim kom muaj lub hauv paus foob uas yog qhov tseem ceeb rau cov khoom thaiv zoo dua.
Txhim khu kev ntub dej thiab nthuav tawm cov yam ntxwv ntawm kev ua haujlwm txheej txheej
Ntxiv nrog rau cov nplaum nplaum, ntau lub siab -kab laminates suav nrog cov txheej txheem ua haujlwm xws li PVdC, EVOH, lossis acrylics los txhim kho cov pa oxygen thiab noo noo barrier. Kev kho mob Corona ntawm cov yeeb yaj kiab tau lees tias cov txheej txheem no tau sib xyaw ua ke thiab faib thoob plaws tag nrho cov substrate nto. Qhov no ua rau lub cev tsis sib xws, pinhole-dawb txheej tuab, uas yog qhov tseem ceeb rau kev ua kom tau raws li qhov tshwj xeeb thiab kev cia siab rau kev ua tau zoo hauv cov yeeb yaj kiab laminated.
Ua kom yooj yim rau kev siv cov khoom sib txawv thiab ruaj khov
Raws li kev lag luam hloov mus rau kev ruaj khov dua, feem ntau nyuaj dua - mus rau - cov ntaub ntawv sib cog lus xws li rov ua dua - cov ntsiab lus plastics lossis bio- raws li cov polymers, lub zog saum npoo tuaj yeem hloov pauv. Kev kho kab mob corona ua tau zoo raws li cov txheej txheem saum npoo av, ua kom cov chaw nyuaj no kom txaus siab rau lub zog lamination adhesion lub zog thiab cov txheej txheem thaiv kev tsim nyog rau kev ntim khoom zoo.
Tus Thawj Coj Kev Lag Luam Daim Ntawv Thov thiab Qhov Zoo
Daim ntawv thov thoob plaws ntim kev lag luam
Technology yog qhov tseem ceeb rau:
