Vim yog qhov tshwj xeeb ntawm cov txheej txheem luam ntawv digital inkjet, UV-kho tau inkjet inks yuav tsum ua kom tau raws li cov kev cai nruj thiab nruj hais txog ntau yam ntawm physicochemical zog.
Viscosity yog qhov tseem ceeb; nws yuav tsum tsis tshua muaj qis-feem ntau nyob rau hauv thaj tsam ntawm 10-30 centipoise (cP) los yog qis dua-kom paub meej tias tus number case tuaj yeem ua tau zoo los ntawm micro-nozzles ntawm lub taub hau printhead thiab tsim cov tee dej ruaj khov.
UV-kho tau inkjet inks yuav tsum tau nyob ze-instantaneous curing (ntawm qhov kev txiav txim ntawm milliseconds) los tiv thaiv cov tee los ntawm kev sib kis los yog los ntshav ntawm lub substrate, kom "ntub-rau-ntub" luam ntawv, thiab kom tsis txhob smudging los yog offsetting.
Nto nro yuav tsum tau tswj kom meej meej kom muaj kev sib npaug ntawm qhov chaw ruaj khov thiab lub davhlau trajectory, thiab zoo ntub dej ntawm cov substrate.
Pigment dispersion yog ib yam khoom tseem ceeb ntawm lub cev uas cuam tshuam rau tus number case chromaticity, opacity, viscosity, thiab tag nrho cov system stability.
Tus number case yuav tsum muaj kev ruaj ntseg ntawm thermal stability ntawm kev khiav hauj lwm kub ntawm lub printhead (feem ntau 40℃-50 degree).
Tsis tas li ntawd, UV-kho tau inkjet inks yuav tsum muaj cov theem tshwj xeeb ntawm cov hluav taws xob conductivity kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob tswj cov tshuab. Xim ceev txiav txim siab xim saturation ntawm cov duab luam tawm, thaum muaj kev xav tau ntxiv txog kev nyab xeeb ntawm ib puag ncig, huab cua tsis kam, thiab kev puas tsuaj.
Ua ke, cov khoom siv physicochemical no tsim lub hauv paus uas ua rau UV inkjet thev naus laus zis kom ua tiav kev luam ntawv zoo thiab muaj txiaj ntsig zoo.
