Kev siv UV txheej rau ntawm daim ntawv luam, qee zaus yellowing phenomenon, nws muaj ob yam tseem ceeb: Ua ntej, UV coating nws tus kheej daj; Qhov thib ob, nyob hauv txoj kev txheej txheem, cov txheej roj tsuas yog kho rau ntawm daim ntawv. Sab hauv tsis tau kho kiag li.
Lub daj ntawm cov kua roj vuas yog muaj feem xyuam rau kev siv cov oligomers thiab cov tshuaj tsis haum nrog cov xim daj. Vim li no, tsis muaj xim tsis muaj zog thiab cov roj reactive yuav tsum siv los tsim cov kua roj vanish. Tsis tas li ntawd, tus cwj pwm ntawm cov duab yees kuj zoo heev, thiab cov duab ntawm cov duab yuav ua rau lub daj daj tom qab tua, xws li benzoin dimethyl ether, yog li siv cov yees duab no yuav tsum zam ntawm cov kua roj vuas.
Hauv txheej txheej, thaum lub sab hauv ntawm cov txheej roj tsis kho, tus txheej txheem thinner cov roj thaw xim yuav maj mam absorbed ntawm tus number case thiab daim ntawv, thiab tib lub sij hawm, nws yuav muaj cov nyhuv ntawm lub binder rau tus cwj mem thiab ua rau muaj roj poob. Cov pigment tsis txaus tiv thaiv thiab cov xim ua pigment yog dawb. Nyob rau lub sij hawm no, tus smoothness ntawm qhov saum npoo ntawm ntawv lo thiab ink number case yuav raug txo. Qhov ntxhib ntog yuav tsim diffuse reflections ntawm lub teeb, muab qee qhov ntawm cov nroj tsuag dawb cov xim rau cov xim, uas yuav ua rau kom ci ntsa iab thiab txo qhov kev tuaj yeem, muab lub tswv yim ntawm zuag qhia tag nrho thiab tshav ntuj. Yog li, txoj kev ceev ntawm UV txheej yuav tsum tau nce lossis tsim kho UV kho kom pom qhov yuav tsum tau xaiv. Tsis tas li ntawd, kev siv cov dej UV kua roj muaj peev xwm tiv thaiv tau cov tshuaj siv ntawm cov kua thev Liu thiab daim ntawv pov tseg, thiab tuaj yeem tsis txhob tso daj ntawm cov ntawv luam tawm.
