UV photopolymerization, tseem hu ua hluav taws xob kho lossis UV kho, yog kev ua si-hloov tshuab uas tau hloov pauv cov txheej txheem tsim khoom rau ze li peb lub hlis twg ntawm ib puas xyoo. Cov txheej txheem tshiab no siv lub zog ultraviolet los tsav kev sib txuas hauv UV-formulated cov ntaub ntawv, xws li inks, coatings, adhesives, thiab extrusion.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm UV kho yog nws lub peev xwm los tsim cov khoom tsim nyog nrog kev kub ceev, me me hneev taw. Qhov no txhais tau hais tias cov ntaub ntawv tuaj yeem hloov pauv los ntawm cov dej ntub dej mus rau ib qho khoom, lub xeev qhuav yuav luag tam sim ntawd. Qhov kev hloov pauv sai sai no tau ua tiav yam tsis tas yuav tsum muaj cov khoom siv ua kua, uas feem ntau yog siv hauv cov pa dej thiab cov kuab tshuaj raws li cov qauv.
Tsis zoo li cov txheej txheem ziab khaub ncaws, UV curing tsis tsuas yog evaporate lossis qhuav cov khoom. Hloov chaw, nws dhau los ua cov tshuaj tiv thaiv uas tsim muaj zog, ntev-ntev kev sib raug zoo ntawm cov molecules. Qhov no ua rau cov ntaub ntawv uas muaj zog heev, tiv taus tshuaj lom neeg puas tsuaj thiab huab cua, thiab muaj cov khoom tsim nyog xws li hardness thiab plam tsis kam.
Hauv qhov sib piv, cov dej ib txwm siv thiab cov kuab tshuaj raws li cov kuab tshuaj tso siab rau cov khoom siv ua kua los pab txhawb kev siv cov khoom siv rau qhov chaw. Thaum ua ntawv thov, cov cab kuj yuav tsum tau evaporated los yog qhuav siv lub qhov cub siv hluav taws xob thiab ziab qhov tunnels. Cov txheej txheem no tuaj yeem tawm hauv qab cov khoom seem uas ua rau khawb, sib tsoo, thiab tshuaj lom neeg puas tsuaj.
UV curing muaj ntau qhov zoo ntawm cov txheej txheem ziab khaub ncaws. Rau ib qho, nws tshem tawm qhov xav tau ntawm qhov cub siv hluav taws xob thiab ziab qhov chaw, txo kev siv hluav taws xob thiab kev cuam tshuam ib puag ncig. Tsis tas li ntawd, UV curing tshem tawm qhov kev xav tau ntawm cov khoom siv hluav taws xob tsis zoo (VOCs) thiab cov pa phem (HAPs), ua rau nws muaj kev xaiv zoo rau ib puag ncig.
Hauv cov ntsiab lus, UV kho yog qhov ua tau zoo thiab siv tau zoo uas muaj ntau yam txiaj ntsig rau cov tuam ntxhab. Nws lub peev xwm los tsim cov ntaub ntawv zoo nrog kev ceev thiab qhov tseeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev lag luam. Los ntawm kev siv lub zog ntawm UV kho, cov tuam txhab tsim khoom tuaj yeem tsim cov ntaub ntawv nrog kev ua tau zoo dua qub, zoo li qub, thiab kav ntev, thaum tseem txo lawv cov kev cuam tshuam ib puag ncig.
