UV inkjet luam ntawv thev naus laus zis tau txais txiaj ntsig thoob plaws ntau qhov chaw luam ntawv vim nws txoj kev kho sai sai, kev tsim cov xim zoo nkauj, thiab eco-phooj ywg, lub zog txuag hluav taws xob. Cov txheej txheem feem ntau suav nrog ntau theem: qauv tsim thiab kev npaj substrate, substrate pre-treatment, digital inkjet luam ntawv, UV curing, thiab tom qab ua tiav. Cov qauv tsim thiab kev npaj substrate suav nrog kev txiav txim siab lossis tsim qhov ntev ntawm cov ntawv luam tawm raws li cov qauv npaj. Thaum kho ua ntej, cov ntaub ntawv sib txawv xav tau kev npaj tshwj xeeb - piv txwv li, cov ntoo saum npoo yuav xav tau qib thiab tshem tawm plua plav, thaum iav yuav xav tau txheej txheej los tiv thaiv delamination. Nyob rau hauv lub digital inkjet luam ntawv theem, cov qauv ntaub ntawv yog loaded rau hauv lub tshuab luam ntawv, luam ntawv tsis configured, thiab lub printhead precisely deposits tus number case mus rau lub substrate nto. UV curing siv ultraviolet irradiation los ua kom muaj kev sib txuas ceev ceev thiab kev sib koom ua ke ntawm oligomers thiab monomers hauv tus cwj mem, uas ua rau muaj cov yeeb yaj kiab ntev. Cov kauj ruam tom qab ua tiav-xws li txhim kho kev hnav tsis kam lossis txiav cov khoom siv rau hauv nws cov duab kawg-yog haum rau cov khoom tshwj xeeb, nrog kev tswj xyuas nruj zoo thoob plaws tag nrho cov haujlwm.
Ntawm qib microscopic, kev npaj ntawm UV-kho tau inkjet number case sawv cev rau cov thev naus laus zis tseem ceeb. Noj UV-curable inkjet number case tsim los rau cov ntaub ntawv cov lej ua piv txwv, cov khoom siv feem ntau muaj cov xim dispersion (xim xim) thiab lub tsheb (cov kua roj vanish). Cov pigment dispersion yog tsim los ntawm qhov nruab nrab dispersion, tus neeg sawv cev dispersing, thiab pigment hmoov; Piv txwv li, UV-kho tau monomer zoo li tetrahydrofurfuryl acrylate (THFA) tuaj yeem ua qhov nruab nrab dispersion, nrog cov neeg sawv cev sib xyaw ua ke siv los cuam tshuam cov xim los ntawm cov txheej txheem milling tshwj xeeb. Lub tsheb muaj monomers, pib, thiab cov neeg ua haujlwm theem; qhov no yuav tsum tau xaiv cov monomers uas muab ceev ceev curing speeds thiab zoo heev pigment wettability, ua ke nrog ib tug blend ntawm ntau photoinitiators los txhim kho cov kev ua tau zoo. Cov txheej txheem ntawm tus number case tuaj yeem ua kom zoo dua-piv txwv li, los ntawm kev kho qhov sib piv ntawm cov neeg pib lossis koom nrog cov polyurethane prepolymers los kho qhov ziab kom qhuav, lossis los ntawm kev ntxiv cov monomers tshwj xeeb, kho qhov kub ntawm lub taub hau, thiab siv cov khoom sib xyaw ua ke los txhim kho tus cwj pwm sib kis thiab luam ntawv precision ntawm lub substrate.
