Kev sib piv ntawm UV Offset Printing Inks hauv Txheej Txheem Luam Ntawv

UV offset printing inks, raws li cov duab nruab nrab hauv kev luam ntawv, ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab tonality, xim saturation, thiab clarity ntawm cov duab luam tawm. Nrog rau kev nce qib hauv kev luam ntawv thev naus laus zis, cov ntaub ntawv substrate, thiab cov qauv muaj feem xyuam, inks yuav tsum hloov mus rau ntau yam substrates thiab txheej txheem luam ntawv, ua rau muaj kev xav tau ntau ntxiv rau inks. Qhov no tau ua rau muaj ntau tus cwj mem formulations, txhua tus muaj cov yam ntxwv tshwj xeeb thiab cov kev siv tshwj xeeb, hais txog cov kev daws teeb meem thiab tshwj xeeb. Thaum xaiv cov inks, cov lag luam luam ntawv yuav tsum tsis yog tsuas yog ua tau raws li lawv tus kheej cov txheej txheem luam ntawv thiab cov kev xav tau zoo tab sis kuj ua raws li VOC cov qauv siv hluav taws xob hauv teb chaws thiab kev tiv thaiv ib puag ncig, yog li txuag nqi thiab tsis txhob muaj teeb meem kev cai.

Hauv ntau hom kev lag luam xws li luam yeeb, cawv, tshuaj pleev ib ce, khoom siv hluav taws xob, khoom noj khoom haus, thiab tshuaj ntim khoom, daim ntawv thov ntawm UV offset inks yog dav, yuav tsum ua raws li kev lag luam tshwj xeeb ib puag ncig. Piv txwv li, hauv kev lag luam hluav taws xob, kev ua raws li IEC 61249-2-21: 2003 tus qauv tsis muaj halogen yog qhov yuav tsum tau ua los tiv thaiv halogen-induced hluav taws xob kev ua tau zoo degradation thiab tsim ntawm ib puag ncig muaj kev phom sij dioxins.

Txawv luam ntawv substrates, nrog rau cov ntawv, zaj duab xis, textiles, hlau, thiab ceramics, nthuav tawm qhov sib txawv ntawm qhov sib txawv vim lawv cov khoom muaj pes tsawg leeg thiab kev kho deg, cuam tshuam rau number case adhesion. Tshaj li adhesion, cov tshuaj sib xyaw ua ke ntawm tus number case thiab substrate yuav tsum raug txiav txim siab kom tsis txhob muaj qhov tshwm sim xws li hauv qab-tom los yog number case discoloration los ntawm leached tshuaj thiab number case re-adhesion.

Cov txheej txheem tom qab luam ntawv zoo li kev tuag-txiav thiab kub stamping ua rau cov kev cai tshwj xeeb ntawm cov cwj mem, yuav tsum tau siv cov inks hloov tau yooj yim nrog cov ntom ntom ntom ntom kom tsis txhob muaj xim tawg thaum ua haujlwm lossis ua tsis tiav hauv cov txheej txheem tiav.

Tsis tas li ntawd, raws li cov khoom siv-xws li daim npav lossis cov ntim tshuaj pleev ib ce-tus number case yuav tsum ua tiav qee yam kev ua tau zoo, xws li kev ua haujlwm siab, cov xim zoo nkauj uas tiv taus fading, thiab zoo heev lightfastness, xyuas kom cov khoom muaj lub ntsej muag zoo nkauj nyob rau lub sijhawm thiab thov rau cov neeg siv khoom.
