Lub tshuab ua kua roj vanish yog cov cuab yeej siv hauv kev lag luam luam ntawv thiab ntim khoom, feem ntau yog siv rau kev kho deg ntawm cov ntaub ntawv tiaj tus xws li ntawv, yas, thiab hlau. Nws lub hauv paus ntsiab lus yog siv ultraviolet lub teeb irradiation los ua cov tshuaj tiv thaiv nyob rau hauv lub photosensitizer, yog li tsim ib txheej ntawm cov kua roj vanish rau ntawm cov khoom nto, pab tiv thaiv, kho kom zoo nkauj, los yog txhim khu kev ua hauj lwm nto.
Cov qauv khoom: Cov kua roj vanish txheej tshuab feem ntau muaj lub tshuab tseem ceeb, lub teeb qhov chaw, tswj txee, conveyor siv, UV teeb, thiab photosensitizer mov system. Lub tshuab tseem ceeb yog lub cev ntawm cov cuab yeej siv, uas suav nrog lub tshuab siv conveyor siv thiab UV teeb tsav system. Lub teeb ci siv lub teeb hluav taws xob siab UV, muaj peev xwm ua kom pom lub teeb ultraviolet nrog lub wavelength ntawm ib ncig ntawm 365nm. Lub txee tswj yog lub luag haujlwm rau kev tswj hwm thiab kev hloov kho ntawm cov khoom siv, tso cai rau kev hloov kho lub sijhawm irradiation thiab kev siv ntawm lub teeb ultraviolet. Txoj siv conveyor yog siv los nqa cov ntaub ntawv, ua kom lawv ruaj khov thaum lub sij hawm irradiation txheej txheem. Cov txheej txheem photosensitizer yog lub luag hauj lwm rau kev sib npaug ntawm cov photosensitizer ntawm cov khoom nto.
Yam Khoom Ua Haujlwm: Thaum cov kua roj vanish txheej tshuab ua haujlwm, cov ntaub ntawv raug xa mus rau hauv lub tshuab ntawm txoj siv conveyor thiab irradiated nrog ultraviolet lub teeb. Lub teeb UV excites lub photosensitizer molecules, ua rau lawv mus rau cov tshuaj tiv thaiv, tsim ib txheej ntawm cov kua roj vanish. Cov kua roj vanish txheej no tuaj yeem tiv thaiv cov khoom nto, txhim kho nws cov hniav zoo nkauj, lossis txhim kho qhov kev ua tau zoo, xws li hnav tsis kam thiab tiv thaiv xeb. Tom qab irradiation tiav, cov ntaub ntawv tseem raug xa tawm ntawm cov cuab yeej, ua tiav cov txheej txheem varnishing. Tag nrho cov txheej txheem yog kev kho mob tas mus li thiab tsis siv neeg, kom ntseeg tau tias muaj txiaj ntsig zoo thiab ruaj khov varnishing.
