1, gloss tsis zoo, cov ci ci tsis txaus, ntxiv rau qhov matte, teeb lub teeb thiab lwm yam teebmeem ntawm UV varnish, nws feem ntau yuav tsum tau hais tias lub siab dua cov gloss ntawm UV varnish yog, qhov zoo dua:
lub ntsiab yog vim li cas
A, UV varnish nws tus kheej yog ib qho me me heev, yog li ntawm cov ntawv lo yog ib yam nkaus thiab nyias
B, ethanol, toluene thiab lwm cov tshuaj tsis haum reactive muaj tshaj
C, gloss ntawm cov yees duab-tau cob nws tus kheej tsis txaus
D, daim ntawv absorption yog qhov muaj zog heev
E, txoj kev ntxhib los mos dhau zoo, ua rau muaj kev hloov me ntsis ntawm cov kua roj vanish. F scraper thiab mesh version tsis tau xaiv.
Tshuaj:
A. Siv cov paj ntaub acrylic acrylic photocuring
B, qhov tsim nyog nce ntawm viscosity varnish
C. Txwv tsis pub tswj tus nqi ntawm ethanol thiab toluene ntxiv
D. Rau daim ntawv uas muaj permeability, koj tuaj yeem thov daim ntawv nqa los yog xaiv ib daim ntawv uas muaj qhov zoo.
E. Txaus siab ua kom lub dav F ntawm tus menyuam qhov quav anilox kom txo tau cov tawv nqaij ntawm qhov hnyav
G. Thaum luam ntawv, koj tuaj yeem xaiv qhov qis mesh ntxiv kom loj tuaj ntawm qhov txheej txheem.
2. Kev luam tawm ntawm UV varnish tsis tuaj yeem ua rau saum npoo ntawm cov ntawv luam tawm:
lub ntsiab yog vim li cas:
A, UV varnish viscosity me me, lub txheej yog ib yam nkaus thiab nyias
B, qhov teeb meem ntawm cov ntawv luam tawm yog oily
C, qhov npoo ntawm tus cwj pwm yog "vitrified", tsis muaj affinity nrog cov kua roj vanish
D, nplaim ntawm tus number case muaj ntau cov khoom siv los tiv thaiv cov nplaum (xws li roj silicone, dusting)
E, coilings anilox yog ib yam nkaus thiab nyias
Tshuaj:
A. Tu cov kev tu vaj tse uas tsim nyog rau cov ntawv luam los ua glazed
B, kom kho cov viscosity ntawm cov kua roj vanish
C. Hom thiab cov nyiaj additives nyob rau hauv cov kua roj vuas ntxiv tau ntxiv, thiab tus nqi qis dua yuav ntxiv tau.
D. So qhov nplai ntawm cov luam tawm nrog 2% alkaline kua.
3. Tom qab cov ntaub ntawv luam tawm yog glazed, lub nplaum nplaum thiab qhuav:
lub ntsiab yog vim li cas:
IB, lub zog UV tsis txaus
B, UV teeb laus laus, tsis muaj zog
C, UV cov kua vev tsuaj tsis yog xaiv tau
D, ethanol, toluene thiab lwm cov kuab tshuaj ntxiv ntau heev
E, lub tshuab ceev ntawv ceev ceev dhau lawm
F, UV varnish muaj cov duab tsis zoo-muaj zog
Tshuaj:
A, tu lub sijhawm rau cov khoom siv thiab hloov cov roj teeb
B, ntxiv ib qhov nqi ntawm cov duab yees thiab cov neeg tsis muaj zog, xws li ternary amine mus ceev cov yees duab-fixation
C, kho cov txheej txheem luam ntawv
4, sis tsis ncaj zis, plooj thiab txiv kab ntxwv plhws phenomenon:
lub ntsiab yog vim li cas:
A, UV varnish viscosity yog siab dhau heev lawm
B, lub siab tsis haum
C, qhov nyiaj ntau yog loj heev
D, qhov cuab yeej ntawm UV varnish yog qhov tsis zoo
E, daim ntawv tsis yog lub tiaj, thiab qhov nqus yog qhov muaj zog heev.
F, UV cov kua roj vov phom tsis zoo
Tshuaj:
A, txo cov viscosity ntawm UV varnish
B, txo cov nqi ntawm txheej, thiab kho tusyees hauv maub
C, ntxiv tau tus nqi qis me me
D. Corona kho cov nplai ntawm cov teeb meem tshwm sim los ua kom muaj qhov sib ze ntawm UV varnish mus rau qhov chaw
5, UV txheej muaj pinhole phenomenon:
lub ntsiab yog vim li cas:
IB, lub txheej yog ib yam nkaus thiab nyias
B, qhov quav anilox yog ib yam nkaus thiab nyias
C, ethanol, toluene non-reactive diluent ntxiv ntau heev
D, cov nplaim luam tawm muaj hmoov av
Tshuaj:
A. Ntxiv dag zog rau kev tu chaw ua haujlwm
B, ntxiv tau ib qho me me ntawm kev sib sau ua ke tus tswv tsev ntxiv, ntxais ntxiv
C, xaiv ib tug UV tshwj xeeb los ua kom lub cev tsis zoo, tiv thaiv kom tsis txhob muaj lub cev tsis ua haujlwm
D, sim ua kom lub thickness ntawm lub txheej thaum luam ntawv
6. Lub hauv paus ntsiab lus tseem ceeb rau lub qab hiav txwv thiab cov fishes nyob saum npoo ntawm cov ntawv luam tawm:
IB, qhov saum npoo ntawm qhov teeb meem luam tawm tsis pom kev, tsis muaj roj ntsha
