Kev Txhim Kho Kev Kho Kom Zoo Rau Ib puag ncig rau Cov Tshuab Luam Ntawv: Cov Khoom Siv UV Kom Qhuav Tawm Los Ua Kev daws teeb meem tseem ceeb rau Kev Tsim Khoom Ntsuab
Thaum muaj kev nruj ntawm cov cai ib puag ncig thiab kev lag luam xav tau kev hloov pauv qis carbon, cov tuam txhab luam ntawv ntsib teeb meem xws li kev tso pa tawm VOC ntau dhau thiab kev siv hluav taws xob ntau. Ua tus kws tshaj lij muab kev pabcuam ntawm Kev ziab Uv cov khoom siv rau cov tshuab luam ntawv, peb qhov kev daws teeb meem kho kom zoo rau ib puag ncig tshiab muab kev txhawb nqa tseem ceeb rau kev txhim kho ntsuab ntawm kev lag luam.
Kev luam ntawv ib txwm siv kev ziab cua sov ntawm cov kua roj uas muaj cov kuab tshuaj, uas tsis yog tsuas yog tso tawm ntau cov tshuaj lom neeg xwb tab sis kuj raug kev txom nyem los ntawm kev siv hluav taws xob ntau thiab kev ziab qeeb. Peb cov khoom siv UV ziab siv cov mercury tsawg. Cov teeb UV thiab thev naus laus zis sib phim spectrum ntse. Los ntawm kev siv ultraviolet irradiation, nws ua tiav cov kua mem qhuav tam sim ntawd (0.1 vib nas this) nrog xoom VOC emissions thoob plaws hauv cov txheej txheem. Cov pa phem ua tau raws li cov qauv hauv tebchaws, daws cov pa phem ntawm qhov chaw.
Nruab nrog lub kaw lus tswj qhov kub thiab txias uas hloov pauv tau thiab lub module rov qab tau cua sov pov tseg, lub kaw lus no txo kev siv hluav taws xob los ntawm 30–50% piv rau cov khoom siv ziab cua sov ib txwm muaj. Nws lub peev xwm kho sai sai hloov kho rau ntau yam khoom siv - suav nrog ntawv, yas, thiab hlau - ua rau kev luam ntawv ceev dua thiab txhim kho kev ua haujlwm ntau lawm.
Ib qho kev tshawb fawb los ntawm lub Hoobkas luam ntawv ntim khoom loj qhia tau hais tias tom qab siv cov kev daws teeb meem no, lub chaw ua haujlwm:
Tau dhau kev tshuaj xyuas ib puag ncig;
Txo cov nqi kho pa tawm los ntawm 40%;
Txhim kho qhov tsis kam ntawm kev luam ntawv thiab txo qis tus nqi tsis lees txais cov neeg siv khoom los ntawm 15% vim yog qhov zoo ntawm kev kho kom zoo; Ua tiav ob qho tib si ib puag ncig thiab kev lag luam yeej.
Raws li Tuam Tshoj Printing Technology Association, Kev Siv Tshuab Kho Kom Zoo Nkauj UV tau dhau los ua qhov kev xaiv tseem ceeb rau kev kho dua tshiab ntawm kev luam ntawv uas tsis ua rau ib puag ncig puas tsuaj. Peb cov kev daws teeb meem muaj daim ntawv pov thawj CE thiab RoHS thiab txhawb kev sib koom ua ke nrog offset, flexographic, thiab lwm yam hom xovxwm. Kev kho dua tshiab ntawm cov tshuab qub txo cov nqi hloov pauv mus txog 60%.
Vim muaj kev nyuaj siab ntau ntxiv rau kev ua raws li ib puag ncig, cov khoom siv UV ziab no muab kev daws teeb meem ntsuab uas tsis muaj pa phem, siv hluav taws xob tsawg, thiab ua haujlwm tau zoo. Nws ua kom kev lag luam luam ntawv hloov mus rau yav tom ntej uas tsis muaj pa phem, ruaj khov.
