Kev luam tawm kev puas tsuaj rau lub cev feem ntau yog tshwm sim los ntawm kev ua kom tsis haum nyob rau hauv tus number case, tab sis UV luam ntawv number case, tsis muaj ib hom tshuaj tsis haum. UV number case tsis muaj tshuaj lom tom qab tua.
Txawm hais tias UV number case tsis muaj tshuaj lom tom qab kho, nws tsis tuaj yeem hais tias tsis muaj kev phom sij kiag li. Vim tias UV number case tseem muaj qee yam ua voos thiab xeb rau daim tawv. Yog tias koj xaiv ntsuab UV number case, koj tuaj yeem zam qhov xwm txheej no.
UV number case yog dab tsi?
UV number case hais txog kev siv UV lub teeb ntawm lub teeb sib txawv thiab lub zog kom ua rau cov monomers hauv tus number case binder polymerize rau hauv cov ntawv polymers, kom tus number case zaj duab xis thiab ua kua qhuav. UV inks tseem yuav rau inks, raws li inks, lawv yuav tsum muaj xim zoo nkauj (tshwj tsis yog tshwj xeeb), luam ntawv zoo yoog raws, tsim nyog kho kom qhuav tus nqi. Nyob rau tib lub sijhawm, nws muaj zoo adhesion thiab hnav tsis kam, tiv thaiv corrosion thiab huab cua tsis kam.
Daim iav ntsuab yog dab tsi?
Cov number case ntsuab yog hais txog kev siv cov khoom tsis muaj teeb meem rau kev tsim cov number case, number case ntau lawm thiab luam ntawv cov txheej txheem yuav luag tsis muaj kuab paug, yuav luag tsis muaj kev phom sij rau tib neeg kev tsim khoom thiab kev nyob ib puag ncig ntawm cov number case. Tshaj tawm kev hais lus, ntsuab number case yog qhov khoom lag luam nyob ib puag ncig. Nws muaj cov hauv qab no 3 lub ntsiab lus:
(1) Cov dej tsis huv ntawm tus number case yuav tsum tau txo qis, suav nrog txo cov ntsiab lus ntawm cov roj uas muaj ntxhiab hydrocarbons thiab ketones, txo cov ntsiab lus ntawm cov hlau hnyav thiab lwm yam khoom tsis zoo rau lub cev tib neeg.
(2) Qhov kev puas tsuaj rau cov neeg ua haujlwm thiab ib puag ncig hauv kev tsim thiab siv tus number case yuav tsum tau txo qis dua, thiab qhov chaw tsim khoom ntawm thawj kab yuav tsum tau ua kom zoo dua.
(3) Los ua kom yooj yim rov ua dua thiab pov tseg ntawm cov ntim khoom pov tseg, tsis tuaj yeem tsis muaj" thiab yog li ntawd.
