xov xwm

Hauv kev luam ntawv, tus cwj mem siv rau kev luam ntawv kuj tau qhia txog cov kev cai sib xws, UV number case rau kev kho sai, kev tiv thaiv ib puag ncig thiab lwm yam zoo ntawm kev lag luam luam ntawv.UV luam ntawv number case thoob plaws hauv offset printing, letterpress, gravure printing, screen printing thiab inkjet luam ntawv thiab lwm yam luam ntawv, tsab xov xwm no qhia UV number case txog kev paub, cov ntsiab lus rau cov phooj ywg siv:

Txhais

UV: luv rau ultraviolet lub teeb.Ultraviolet (UV) tsis pom ntawm qhov muag liab qab.Nws yog ib feem ntawm hluav taws xob hluav taws xob uas tsis yog pom lub teeb liab.Lub wavelength yog nyob rau hauv thaj tsam ntawm 10 ~ 400nm

UV number case: UV number case, hais txog UV teeb irradiation instant curing number case

Yam ntxwv

1, lub ziab ziab yog ceev ceev, txuag lub sij hawm, nyob rau hauv UV teeb irradiation, xav tau ob peb vib nas this mus rau ob peb vib nas this yuav kho tau.

2, cov khoom siv npog thaj tsam me me, luam ntawv khiav lag luam, txuag cov neeg ua haujlwm, cov txiaj ntsig kev lag luam.

3, tshaj li txhua tus cwj mem tshwj tsis yog ntuj evaporation ziab khaub ncaws, tuaj yeem txuag hluav taws xob.

4, nyob rau hauv cov ntaub ntawv ntawm tib lub qhuav zaj duab xis thickness, ntau number case txuag.

5, yuav tsis crust, tsuav yog tsis hu rau ultraviolet hluav taws xob yuav tsis qhuav khoom ntawm tus number case.

6, xim zoo stability.

7, siab brightness.

8, number case me me, tuaj yeem luam cov qauv zoo.

9, luam ntawv ib puag ncig huab cua yog tshiab, tsis hnov ​​tsw, tsis muaj VOC.

Cov khoom xyaw tseem ceeb

Cov khoom tseem ceeb ntawm UV number case muaj xws li pigment, oligomer, monomer (active diluent), photoinitiator thiab ntau yam auxiliaries.Ntawm lawv, resin thiab nquag diluent ua lub luag haujlwm ntawm kev kho cov xim thiab muab cov yeeb yaj kiab tsim cov khoom;Pigments muab tus cwj mem xim xim thiab npog lub zog rau lub substrate;Photoinitiator yuav tsum muaj peev xwm nqus tau photons nyob rau hauv kev cuam tshuam ntawm pigments los pib polymerization.

1, Monomolecular Compounds (reactive diluent)

Qhov no yog ib qho yooj yim compound nrog me me molecular hnyav, nws yuav txo tau viscosity, ua lub luag hauj lwm dispersive, muaj peev xwm disperse pigments, yaj resin, txiav txim siab curing ceev thiab adhesion ntawm number case, thiab koom nyob rau hauv UV resin curing crosslinking cov tshuaj tiv thaiv.

2, Additives

Xws li cov pigments, lubricants, thickening tus neeg saib xyuas, muab tub lim, solidifying tus neeg sawv cev, thiab lwm yam. Nws cuam tshuam rau tus number case gloss, viscosity, softness, xim, zaj duab xis thickness, curing ceev, luam ntawv haum thiab lwm yam khoom.

3, Lub Teeb Khoom Resin nws yog UV Ink Txuas Khoom

UV number case curing ceev, gloss, adhesion, kev sib txhuam tsis kam thiab lwm yam khoom, cov cwj mem sib txawv muaj ntau hom sib xyaw ua ke.

4, Lub teeb Initiator

Lub teeb pib ua tus choj ntawm cov tshuaj tiv thaiv tshuaj, yog ib yam ntawm lub teeb excitation ua active heev, tom qab absorbing photons tsim dawb radicals, dawb radical hloov lub zog mus rau lwm yam photosensitive polymer, tsim ib tug saw cov tshuaj tiv thaiv, ib tug molecule khoom, additives, lub teeb khoom resin. ua ke, ua kom tus number case curing cov tshuaj tiv thaiv, thiab tom qab kev tso tawm ntawm lub zog nyob rau hauv nws tus kheej yog tsis koom nrog crosslinking cov tshuaj tiv thaiv.

Txoj Cai Solidification

Nyob rau hauv lub irradiation ntawm ultraviolet lub teeb, lub teeb pib lub zog nqus los tsim cov dawb radicals, dawb radical kev ua si ntawm kev kub ceev, kev sib tsoo tshwm sim nrog resin thiab ib qho molecular compound, hloov lub zog rau resin thiab ib qho molecule compounds, resin thiab ib qho molecular compound. Tom qab absorbing zog excitation uas muaj unsaturated ob daim ntawv cog lus atoms polymerized monomer polymer thiab radicals, uas yog, resin thiab ib tug molecule tebchaw, Lawv qhib ob daim ntawv cog lus thiab pib ib tug cross-linking cov tshuaj tiv thaiv, ib tug cross-linking kho, uas lub photoinitiator poob lub zog thiab rov qab los. mus rau nws lub xeev qub.

Tej yam cuam tshuam

UV curing number case yuav tsum muaj UV teeb los kho, txwv tsis pub nws siv tsis tau.Hauv kev siv UV number case, thawj qhov teeb meem adhesion yog tias UV number case tsis muaj qhov tob tob.Nyob rau hauv cov nqe lus ntawm lub teeb khoom siv, vim li cas tej zaum yuav tsis ua hauj lwm ntawm UV curing khoom, uas yog, lub wavelength ntau yam ntawm UV curing khoom tsis phim UV lub teeb khoom number case, los yog lub teeb lub zog tsis txaus, los yog lub teeb ceev ceev yog tsis. tsim nyog.

1, lub teeb xim xim UV lub teeb khoom spectral rhiab heev rau wavelength ntawm 180-420NM.

2, lub hwj chim ntawm UV teeb yuav tsum ua tau raws li cov txheej txheem kev cai ntawm ink curing.

3, luam ntawv ceev heev kuj cuam tshuam rau kev kho ceev ntawm number case.

4, tus cwj pwm ntawm tus number case thickness, number case yog tuab heev yuav cuam tshuam cov nyhuv curing, tag nrho cov yam cuam tshuam rau lub thickness ntawm printing zaj duab xis yuav cuam tshuam cov nyhuv curing.

5, qhov cuam tshuam ntawm kev nyab xeeb: kub kub, UV number case viscosity yuav qis, tom qab luam ntawv, yooj yim los tsim paste version phenomenon.Tsis tshua muaj kub, siab viscosity, cuam tshuam rau thixotropy ntawm number case, rhiav kub tsis tuaj yeem siab dhau heev lawm, thaum lub caij ntuj no hauv lub tsev khaws khoom cua txias, yuav tsum tau muab tso rau hauv chav tsev kub, thiab tsim nyog ua kom qeeb ntawm kev kho ceev.

6, kev cuam tshuam ntawm cov xim ntawm UV number case: vim muaj ntau yam xim ntawm lub teeb nqus, kev xav thiab cov ntsiab lus xim ntawm tus number case feem ntau, dawb, dub, xiav yog qhov nyuaj rau kho, liab, daj, lub teeb roj, pob tshab roj yooj yim kho. .
