UV phev raug tsim tau thaum ntxov xyoo 1940, tab sis lawv tsuas tau tsim nyob hauv 20 xyoo dhau los, thiab kev lag luam muaj kev to taub txog UV dua. Txawm li cas los xij, vim muaj tus nqi siab ntawm UV inks, cov peev nyiaj loj hauv cov cuab yeej kom qhuav, thiab kev siv cov txheej txheem ntau nyuab dua cov pa roj carbon monoxide, cov no tau hindered lawv daim ntawv thov dav dua.
Kev sib hloov ntawm niaj hnub luam tawm nyob rau hauv cov kev coj ntawm cov yoo mov, ntau xim ib zaug luam tawm kuj tau muab rau cov qauv tshiab rau hauv cov phev. Yog li no, qhov zoo ntawm UV cov phev ntev tshaj yog qhov tseem ceeb tshaj plaws. Piv txwv, UV phev tsis tau qhuav rau hauv xovxwm, tiam sis tuaj yeem qhuav ntawm cov luam tawm, uas ua tau raws li cov cai ntawm cov ntawv luam tawm los ntawm kev luam ntawv thiab cov kev cai ntawm kev ua haujlwm siab, ntau cov xim.
Ntxim rau xim ntawm kev tua
Yuav kom ua tau raws li cov kev xav tau siab, nws tsis txaus kom tso siab rau peb thawj xim xim, thiab nws yog qhov yuav tsum tau siv qhov chaw xim xim. Txawm li cas los xij, rau UV inks, qee cov xim sib txuam yuav lwv nrog cov yees duab los yog cov neeg tsim khoom rau cov xwm txheej UV hluav taws xob. Yog li, qhov kawg absorbs lub radiant zog, kom lub ultraviolet lub teeb irradiated mus rau ntawm lub UV number case tsis tau ncaj qha mus kis tau los ntawm, thiab tsuas yog tom qab ntau reflections thiab lub teeb scattering bypasses saum-hais xim hais kom mus txog hauv qab ntawm cov ink number, ua kom qis qis qis, Tsawg kom qhuav qis.
Muaj ntau txhiab tus pigment uas muaj nyob rau hauv UV number case, yog li UV lub teeb yuav tsum muaj lub zog txaus los mus rau hauv qab ntawm tus number case txheej. Yog tias qhov teeb meem tsis txaus, qhov hauv qab ntawm tus number case yog tsis irradiated nrog ultraviolet lub teeb, tus number case yuav tsis kho kiag li, thiab txheej txheej ntawm tus number case txheej yog tawv thiab muag sab hauv, thiab cov nplaim yog ntsws los ntawm qhov ntswg thaum lub sij hawm polymerization, uas cuam tshuam rau cov luam ntawv zoo. Nyob rau tib lub sijhawm, nws yuav tsum raug sau tseg tias kev kho cov kab mob UV yog txawv ntawm kev tua cov kab mob UV varnishes. Ntxiv nrog rau qhov kev cuam tshuam rau kev kho ntawm UV inks, pigments tseem cuam tshuam cov viscosity, fluidity, wettability, leveling, etc. ntawm tus number case txheej; thiab kev sib cuam tshuam ntawm cov pigment thiab cov cwj pob reactive kuj yuav ua rau txo qis dua hauv lub sij hawm cia lossis teeb meem xws li cov kev hloov hauv cov xim.
Pigment xim thiab kho
Thaum qee cov pig daj daj raug siv nyob rau hauv lub tshuab photoinitiator uas muaj acrylates thiab amines, cov xim ntawm tus cwj mem hloov zoo heev. Qhov nyuaj rau kho cov pigments yog xim dub, dawb, phthalocyanine thiab daj pigments. Dawb thiab dub muaj ob qho yeeb yam tshwm sim, dawb ua rau pom qhov kaj, thiab dub tsis muaj lub teeb rau txhua tus.
Nws txawm xav hais tias nws yuav tsis ua kom dhau UV lub teeb los ntawm ib zaj duab xis txheej muaj ib co thickness thiab ua opaque mus rau lub teeb, tab sis optimizing cov kev kho mob yuav pab kom zoo tua ntawm cov pigment-muaj UV number case. Qee qhov teeb meem nws tau daws los sis zoo dua los ntawm xaiv tus yees duab thiab cov xim raws li cov yam ntxwv ntawm kev nqus ntawm pigment los ntawm UV lub teeb, thiab cov nyhuv ntawm txoj kev tua kab kuj tuaj yeem txo los ntawm kho UV teeb ci.
Pigments sib txawv muaj cov yam ntxwv ntawm kev nqus, kev xav thiab tawg ntawm lub teeb, yog li cov degree ntawm hindrance mus rau UV curing kuj sib txawv. Feem ntau cov pigments muaj qee qhov chaw nyob rau hauv cov cheeb tsam hauv UV thiab qhov pom kev, uas yog hu ua "pigment". Lub qhov muag ntawm lub qhov muag "lub qhov muag" yog qhov tseem ceeb tshaj rau kev xaiv ib tus yees duab uas tsim nyog. yuav tsum tau ua kom tsis pub dhau lub wavelength ntau yam uas cov xim paim absorbs tsawg dua UV. Yog li, yuav tsum tau saib xyuas thaum siv UV inks kom ua tib zoo soj ntsuam cov kev sib raug zoo ntawm cov xim thiab qhov cuam tshuam ntawm tus yees duab.
Txoj kev kho ntawm UV phom txawv ntawm cov xim txawv txawv, vim tias cov wavelengths ntawm lub teeb tsis pom los ntawm cov xim sib txawv ntawm cov xim sib txawv nyias txawv nyias, thiab qhov ze ntawm lub wavelength ntawm lub siab xav mus rau lub wavelength ntawm UV lub teeb, qeeb qeeb ntawm txoj kev ceev, yuav tsum tau UV lub teeb. Qhov siab dua zog; conversely, qhov kev kho sai dua, txo qis UV lub teeb zog. Yog li, txoj kev tiv thaiv UV ceev nrooj yuav tsum muab kho rau cov xim sib txawv kom tsawg los txo cov nyhuv xim ntawm number case curing.
Cov pigment ntawm tus cwj mem tsis zoo tib yam tsis tshua muaj kev cuam tshuam cov ziab lub zog. Cov cim huam sib txawv ntawm cov pigments sib txawv, cov khoom qub thiab tib pabcuam, tab sis qhov teeb meem ntawm UV number case yog txawv kiag li, vim hais tias cov pigments ntawm txawv xim muaj ntau wavelengths ntawm lub teeb. Xaiv lub nqus dej kom zoo thiab muaj cai khwv yees, qhov ua kom sib xyaw ntawm cov Hawj Xim txawv tsis zoo ib yam. Tsis tas li, luam ntawv yuav tsum sib tov sib txawv xim ntawm number case, uas yog, xim txuam, vim muaj xim yog ntawm kev tsim ntawm kev sib xyaw xyaw, ces yog UV number case; kuj xav txog lub zog ntawm lub plab hnyuv tws, ntawm qhov pigment thiab lwm yam khoom. Tseem ceeb ntawm kev sib txuas lus, kev haum ntawm UV lub teeb los ntawm cov xim, thiab lwm yam., Yog tias muaj kev txaus siab, nws yuav tsis txo qhov kev kho kom ceev, thiab ua rau txoj kev ua kom muaj teebmeem, ntxiv rau qhov sib txawv ntawm cov xim, kuj Nws yog qhov nyuaj tshaj rau tus tswv, thiab nws yog ib qhov tsim nyog yuav tau xyaum thiab nrhiav kom tau ib txoj kev kho kom haum. Cov kev sib raug zoo ntawm kev xa tawm ntawm UV lub teeb mus rau ib lub pigment ntxhia roj rho tawm uas muaj ib qho concentration ntawm 10% thiab qhov puav pliaj ntawm UV lub teeb. Cov curves no sib txawv ntawm wavelength, tab sis nyob rau ntawm ib lub suab tsho, magenta xim feem ntau muaj lub siab tshaj plaws, thiab lwm tus yog daj, cyan, thiab dub, uas yog sim curves UV teeb siv thiab kev kho kom ceev. Cov kev faib raws nraim qhov sib txawv.
Rau UV cov phev tshuaj uas muaj xim dawb los sis dub, vim muaj peev xwm ua kom pom tseeb ntawm lub kaum sab xis ntawm tag nrho cov pom pom, lub zog dua yuav tsum tau kho kom zoo. Ntawm qhov tsis sib xws, txawm hais tias dub tau nqus tau tag nrho lub teeb, nws yog vim muaj xim hais. Cov nyhuv nyhuv ntawm qhov kaj kuj huas txoj kev sib sib zog nqus ntawm tus cwj mem, ces nws kuj yuav tsum tau muaj zog dua, yog li txoj kev ceev ceev yog qeeb qeeb.
Cov xim dawb feem ntau yog siv cov titanium dioxide (TiO2), uas ua rau pom lub teeb ntawm ib lub tsho ntawm 380 nm, thiab tseem muaj kev cuam tshuam cov teeb uas muaj lub qhov ntev ntawm 420 nm. Yog li no, lub wavelength ntawm lub teeb pom kev zoo yog li ntawm 380 mus rau 420 nm, uas yog lub teeb-ntxias. Kev xaiv ntawm tus neeg sawv cev xaiv tsa tau nce siab ntxiv. Thaum xaiv ib tug yees duab, lub spectrum absorption yuav tsum tau soj ntsuam kom nws tuaj yeem phim rau cov pa roj carbon lim dej ntawm UV teeb, thiab nws tuaj yeem nqus tau cov ncov hauv cov kabmob ntau qhov chaw uas xaiv cov pigment uas tsis muaj zog UV haum, thiaj li yuav kho tau nrog ib nrab ntawm lub dag zog. nyhuv. Dub pigments nqus hauv tag nrho cov spectrum pom. Yog li ntawd, tus number case dub yog qhov nyuaj tshaj plaws los kho. Nws yog qhov nyuaj rau lub pigments nrog zoo nkaum lub hwj chim thiab cov dub txheej kom muaj ib lub thickness ntawm 20μm los yog ntau tshaj. Qib cov xim dub tau zoo heev ntawm kev tua kab. Tsis tas li ntawd, kev siv cov pigments tshwj xeeb kuj tseem hloov tau qhov teeb meem no.
Tam sim no, UV number case pigments tau tiav qee yam tau ua hauv tshuab, xws li cov khub tshiab tsim acetylphosphorus oxide photoinitiator, BASF thiab Tsinghua Unisplendour tus TPO thiab Ciba refined BAPO hom rau qhov no. Tus yees duab, uas nws lub cev nqus dej tob tob ntev tshaj li ib tus qauv yees duab, thiab nws tsim nyog rau txoj kev ua pigmented. Tau kawg, tseem muaj ntau yam tseem ceeb rau kev kawm, uas yuav tsum muaj kev sib koom tes ntawm cov neeg hauv kev lag luam.
