Kev Luam Ntawv UV: Kho ntawm qhov ceev ntawm lub teeb, ci ntsa iab rau Cov Qib Siab Tshiab hauv Kev Luam Ntawv Niaj Hnub
Hauv kev nrhiav kev ua haujlwm tau zoo, kev phooj ywg ib puag ncig, thiab kev zoo hauv kev luam ntawv
kev lag luam, YAGUANG UV luam ntawv thev naus laus zis tau dhau los ua lub hauv paus tseem ceeb hauv kev lag luam offset
luam ntawv, luam ntawv gravure, luam ntawv flexographic, txheej, luam ntawv hlau, thiab kev kub ceev
cov tshuab nias rotary, ua tsaug rau nws qhov kev zoo nkauj tshwj xeeb ntawm "kev kho tam sim ntawd." Lub hauv paus zais cia nyob rau hauv
kev koom tes meej ntawm lub teeb thiab chemistry.
Lub Khawv Koob ntawm Lub Teeb: Kev Kos Duab Luam Tawm Tam Sim Ntawd
Lub plawv ntawm UV luam ntawv nyob rau hauv nws cov kua tshwj xeeb lossis cov varnishes. Cov ntaub ntawv no muaj ib
cov khoom tseem ceeb hu ua "photoinitiator." Thaum raug rau lub teeb ultraviolet (UV) ntawm ib qho
qhov tshwj xeeb wavelength lossis ntau lub zog txuag LED-UV teeb, lub photoinitiator tam sim ntawd
nqus cov zog teeb thiab tsim cov tshuaj reactive, ua rau muaj kev sib txuas sai sai
polymerization ntawm monomers thiab oligomers nyob rau hauv cov kua mem / varnish. Cov txheej txheem no tsis yog qhov
qeeb qeeb ziab uas cov kua mem ib txwm siv los ntawm kev ua kom yaj lossis zaj duab xis oxidative
kev tsim; es tsis txhob, nws ua tiav qhov kev hloov pauv ntawm cov kua mus rau cov khoom khov hauv feem ntawm a
qhov thib ob, ua tiav "luam tawm thiab qhuav tam sim ntawd."
Cov Kev Zoo ntawm Kev Ci Ntxoov: Lub Hauv Paus Muaj Zog rau Kev Siv Ntau Yam
Qhov kev kho mob sai sai no coj kev txhim kho tshiab rau
ntau txoj kev luam ntawv:
Kev Ua Haujlwm Zoo thiab Ceev: Tshwj xeeb tshaj yog rau kev ua haujlwm ceev ceev ntawm cov tshuab rotary, tshem tawm qhov xav tau kev ziab thiab ua kom ceev ntau ntxiv.
Zoo heev: Cov kua mem uas kho tau zoo no muaj cov xim ntom ntom, xim puv thiab ci ntsa iab, ci ntsa iab, thiab tiv taus kev puas tsuaj thiab khawb zoo heev, tshwj xeeb tshaj yog siv rau kev luam ntawv hlau (rau kev ntim hlau) thiab kev luam ntawv khoom kim heev. Kev Sib Txuas Lus Dav Dav: Kev Kho Mob UV muaj kev nplaum zoo rau cov ntaub ntawv uas tsis nqus tau xws li yas, hlau, iav, daim ntawv nplaum, thiab txawm tias cov ntawv tshwj xeeb, ua rau cov ciam teb ntawm kev luam ntawv offset, gravure, thiab flexographic nthuav dav heev.
Kev Ua Haujlwm Tseeb: Cov txheej txheem kho tsis muaj cov kuab tshuaj evaporation, ua rau cov txheej kua mem tsawg kawg nkaus thiab muaj qhov tseeb ntawm kev luam ntawv siab heev, ua rau nws tsim nyog rau cov xwm txheej nyuaj xws li kev luam ntawv hluav taws xob raug.
Kev Txhim Kho Ntsuab: Cov thev naus laus zis UV (tshwj xeeb tshaj yog LED-UV) txo qis lossis tshem tawm cov pa phem volatile organic compound (VOC) thiab siv hluav taws xob tsawg dua piv rau cov tshuab ziab khaub ncaws ib txwm muaj, ua raws li qhov sib txawv ntawm kev luam ntawv ntsuab. Hauv cov txheej txheem txheej, UV varnishing kuj muab kev daws teeb meem sai thiab zoo rau ib puag ncig.
Lub Cev Tseem Ceeb: YAGUANG UV/LED-UV Lub Teeb Ci
Ruaj khov thiab ua haujlwm tau zoo YAGUANG Cov Tshuab Kho Kom Zoo Nkauj Uv lossis LED-UV curing systems yog "engine"
uas ua rau txhua yam no ua tau. Cov txheej txheem niaj hnub no tuaj yeem tswj tau qhov ci ntsa iab,
wavelength, thiab lub sijhawm raug, ua kom ntseeg tau tias cov teebmeem kho zoo meej rau ntau yam inks / varnishes
hauv cov tshuab luam ntawv offset, cov tshuab luam ntawv gravure, cov kab luam ntawv flexographic, cov chav txheej, cov hlau
cov kab luam ntawv, thiab ntau yam khoom siv rotary.
Kev luam ntawv UV, nrog lub teeb ua nws txhuam thiab lub zog ntawm kev kho tam sim ntawd, txuas ntxiv sau ib
tshooj yav tom ntej ntawm kev ua haujlwm tau zoo, zoo, thiab kev txhim kho kom ruaj khov ntawm daim ntaub loj ntawm
kev luam ntawv, dhau los ua lub teeb pom kev zoo tseem ceeb hauv kev lag luam luam ntawv niaj hnub no.
