UV Printing yog ib txoj hauv kev tshwj xeeb

Cov txheej txheem ntawm UV curing - cov txheej txheem photochemical ntawm ziab - yog thawj zaug qhia raws li ib txoj hauv kev kom qhuav gel ntsia thawv polishes sai sai siv hauv manicures, tab sis nws tsis ntev los no tau txais los ntawm kev lag luam luam ntawv uas nws tau siv los luam tawm ntawm txhua yam los ntawm kos npe thiab daim ntawv qhia rau npias fwj. Cov txheej txheem yog tib yam li ib txwm luam ntawv, qhov sib txawv tsuas yog cov inks siv thiab cov txheej txheem ziab - thiab cov khoom lag luam zoo tshaj plaws.

Nyob rau hauv ib txwm luam ntawv, hnyav inks yog siv; cov no tuaj yeem evaporate thiab tso tawm cov tshuaj tsis haum tshuaj organic (VOCs) uas tsim kev puas tsuaj rau ib puag ncig. Txoj kev kuj tsim - thiab siv - cua sov thiab ib qho tsw nrog. Tsis tas li ntawd, nws yuav tsum muaj cov tshuaj tsuag ntxiv los pab nrog cov txheej txheem ntawm tus number case offsetting thiab ziab, uas tuaj yeem siv sijhawm ob peb hnub. Cov inks yog absorbed rau hauv lub tshuab luam ntawv nruab nrab, yog li cov xim yuav zoo li ntxuav tawm thiab faded. Cov txheej txheem luam ntawv tsuas yog siv rau cov ntawv thiab daim npav nruab nrab, yog li nws tsis tuaj yeem siv rau ntawm cov ntaub ntawv xws li yas, iav, hlau, ntawv ci lossis acrylic zoo li UV luam ntawv.

Nyob rau hauv UV luam ntawv, mercury / quartz los yog LED teeb yog siv los kho es tsis txhob kub; qhov tshwj xeeb tsim high-siv UV lub teeb ze ze raws li tus cwj mem tshwj xeeb tau muab faib rau ntawm qhov nruab nrab luam ntawv, ziab nws sai li sai tau thaum nws siv. Vim tias tus number case hloov los ntawm cov khoom lossis muab tshuaj txhuam rau hauv cov kua yuav luag tam sim ntawd, tsis muaj lub sijhawm rau nws evaporate thiab yog li tsis muaj VOCs, cov pa phem lossis ozone raug tso tawm, ua rau cov thev naus laus zis zoo ib puag ncig nrog yuav luag xoom carbon footprint.

Cov kua nplaum, nplaum los yog txheej muaj cov khoom sib xyaw ua kua monomers, oligomers - polymers uas muaj ob peb qhov rov ua dua tshiab - thiab photoinitiators. Thaum lub sij hawm kho, lub teeb siv hluav taws xob siab nyob rau hauv ultraviolet ib feem ntawm lub spectrum, nrog lub wavelength ntawm 200 thiab 400 nm, yog absorbed los ntawm photoinitiator uas dhau los ua cov tshuaj tiv thaiv - tshuaj lom neeg sib txuas - thiab ua rau tus number case, txheej lossis nplaum kom tawv sai sai.

Nws yooj yim pom tias vim li cas UV luam ntawv tau dhau los ntawm cov dej ib txwm siv thiab cov txheej txheem ua kom qhuav raws li thermal drying thiab vim li cas nws thiaj li yuav tsum tau nce ntxiv hauv cov koob meej. Tsis tsuas yog cov txheej txheem ua kom ntau lawm - lub ntsiab lus ntau dua yog ua tiav nyob rau hauv tsawg lub sij hawm - tsis lees txais cov nqi raug txo vim qhov zoo dua. Cov tee dej ntawm tus number case raug tshem tawm, yog li tsis muaj qhov rub tawm lossis smudging, thiab vim tias qhov ziab yuav luag tam sim ntawd, tsis muaj evaporation thiab yog li tsis muaj qhov poob ntawm txheej tuab lossis ntim. Cov ntsiab lus zoo dua yog qhov ua tau, thiab cov xim zoo dua thiab pom tseeb dua vim tias tsis muaj qhov nqus ntawm cov luam ntawv nruab nrab: xaiv UV luam ntawv tshaj li cov qauv luam ntawv yuav yog qhov sib txawv ntawm kev tsim cov khoom kim heev, thiab qee yam uas xav tias tsis tshua muaj txiaj ntsig.

Cov inks kuj tau txhim kho lub cev lub cev, txhim kho gloss tiav, zoo dua khawb, tshuaj lom neeg, hnyav thiab hardness kuj, zoo elasticity thiab cov khoom tiav kuj tau txais txiaj ntsig los ntawm kev txhim kho lub zog. Lawv kuj muaj ntau ruaj thiab huab cua resistant, thiab muaj kev tiv thaiv kom fading ua rau lawv zoo tagnrho rau sab nraum zoov signage. Cov txheej txheem kuj tseem raug nqi ntau dua - cov khoom lag luam ntau dua tuaj yeem luam tawm hauv lub sijhawm tsawg, ntawm qhov zoo dua thiab muaj kev tsis lees paub tsawg dua. Qhov tsis muaj VOCs tso tawm yuav luag txhais tau tias tsis muaj kev puas tsuaj rau ib puag ncig thiab kev coj ua zoo dua qub.
